ABSTRACT  
This study evaluates the effect of religious distance on bilateral beef trade flows  
between 21 exporting countries and 167 importing countries from 2000 to 2021.  
The analysis examines both facilitating and hindering effects of religious factors  
on commercial flows. Religious similarity may reduce transaction costs through  
shared norms and trust networks, while religious differences may create exclu-  
sionary practices functioning as trade barriers. Using a structural gravity model,  
the results show that religious asymmetry does not impact overall beef trade  
flows, except when controlling for major Halal and Kosher-certified exporters.  
The findings reveal that religion does not systematically affect beef trade, thou-  
gh certification creates competitive advantages in specialized market segments.

RESUMO  
Este estudo avalia o efeito da distância religiosa nos fluxos de comércio bilateral de  
carne bovina entre 21 países exportadores e 167 países importadores de 2000 a 2021. A  
análise examina tanto os potenciais efeitos facilitadores quanto restritivos dos fatores  
religiosos nos fluxos comerciais. A similaridade religiosa pode reduzir custos de tran-  
sação por meio de normas compartilhadas e redes de confiança, enquanto diferenças  
religiosas podem criar práticas excludentes que funcionam como barreiras comerciais.  
Utilizando um modelo gravitacional estrutural, os resultados mostram que a assime-  
tria religiosa não afeta os fluxos comerciais gerais de carne bovina, exceto quando  
controlados os principais exportadores certificados Halal e Kosher. Os achados reve-  
lam que a religião não afeta sistematicamente o comércio de carne bovina, embora a  
certificação crie vantagens competitivas em segmentos especializados globalmente.

RESUMEN  
El estudio evalúa el efecto de la distancia religiosa en los flujos de comercio  
bilateral de carne de vacuno entre 21 países exportadores y 167 países importa-  
dores de 2000 a 2021. El análisis examina tanto los potenciales efectos facilita-  
dores como restrictivos de los factores religiosos en los flujos comerciales. La  
similitud religiosa puede reducir los costos de transacción a través de normas  
compartidas y redes de confianza, mientras que las diferencias religiosas pueden  
crear prácticas excluyentes que funcionan como barreras comerciales. Utilizan-  
do un modelo gravitacional estructural, los resultados muestran que la asimetría  
religiosa no afecta los flujos comerciales generales de carne de vacuno, excepto

1 INTRODUCTION  
International trade is necessary for ensuring food security and  
maintaining public food reserves. A 14% global supply expansion in the  
meat market is anticipated by 2030, accompanied by a 5.9% rise in beef  
availability (OECD-FAO, 2024). This growth trend is also observed on  
the demand side. The consumption of animal protein is driven by dietary  
changes resulting from urbanization and rising global average income.  
Consequently, there is an anticipated increase in international meat flo-  
ws, particularly towards Asia and the Middle East (OECD-FAO, 2024).  
Although commodity trade is generally associated with products that  
have uniform characteristics, are produced on a large scale and with homo-  
geneous physical attributes (Martins; Martinelli, 2010), products can be dif-  
ferentiated by historical, institutional and cultural factors, such as religious  
traditions and cultural ties (Ermgassen et al., 2021; Carneiro et al., 2022). This  
is especially applicable in the meat trade, which, despite being categorized  
as a commodity, may be ascribed other characterizations that are not solely  
reliant on its physical and observable characteristics (Fonseca et al., 2021).  
International negotiations have included specific provisions for  
meat products, considering unobservable quality attributes, including  
adherence to processing and slaughter methods, which are essential  
for markets influenced by religious beliefs. Regulations that define the-  
se qualities can influence market access and generate trade possibilities  
(DallAzen; Weise, 2014).  
The Halal industry, which follows processing rules following the  
Islamic religion, encompasses more than 1.8 billion consumers across 112  
countries. By 2030, the industry is expected to continue growing, given  
the forecast that the Muslim population will reach 29% of the global po-  
pulation (Daud; Lee, Ismail; 2022). Furthermore, the number of young  
Muslims with higher educational levels is rising, reflecting the growth of  
a new market segment with high purchasing power, estimated at appro-  
ximately USD 2.57 trillion by 2024 (Hossain et al., 2021).

Similarly, the Kosher meat business offers appealing possibilities.  
The term Kosher denotes items prepared by Jewish law and is linked to  
health and hygiene due to rigorous food processing, demanding coope-  
ration and transparency from supplying companies (Hossain et al., 2021;  
Rudy et al., 2019). In 2021, the global Jewish population was predicted  
to be roughly 15.2 million, constituting about 0,195% of the total global  
population (DellaPergola, 2022). The primary slaughter requirements for  
this religious group require the animal’s vitality and awareness during  
the slaughter and the complete removal of blood, which is considered  
impure and unsuitable for consumption (Rudy et al., 2019).  
Halal and Kosher products not only represent religious symbols  
with potential for the Islamic and Jewish consumer markets, are also as-  
sociated with excellence in quality assurance, attracting non-Muslim and  
non-Jewish consumers who value quality, safety, health, and authenticity  
(Hossain et al., 2021; Abdul-Talib; Abd-Razak, 2013). To ensure these cha-  
racteristics, religious agencies must certify products which attest to com-  
pliance with technical standards and the brand’s symbol.  
In the realm of certifications, trust among the parties involved is  
important, influencing the selection of the governance framework and  
commercial partner to guarantee reliability. Implementing procedu-  
res that cultivate trust among agents is essential for alleviating uncer-  
tainty, deterring opportunistic behavior, and reducing transaction costs  
(Colares-Santos; Shanoyan; Schiavi, 2020).  
However, religious and cultural issues, when incorporated into  
contracts, can be considered trade barriers (Audu; Okorie; Orekoya, 2023).  
Companies wishing to export products in compliance with religious re-  
quirements must adapt their production processes to the standards esta-  
blished by their trading partners to ensure market access (Aguiar, 2020).  
This leads to additional costs that may reduce exporters’ competitiveness,  
with the consequences of leaving the market.  
Eventually, this is questioned. Audu; Okorie; Orekoya (2023) sta-  
te that religious asymmetries appear to have little impact on trade flo-  
ws, even when comparing the most and least religious nations globally.  
Regardless of the level of religiosity, countries do not typically form trade  
partnerships based on shared religious beliefs. Instead, trade reciprocity  
and economic considerations are more relevant in shaping trade. For ins-  
tance, countries with high levels of religiosity, such as Israel, Saudi Arabia,  
and India, continue to maintain stable trade relations with nations that do  
not share their religious traditions, indicating that religion does not di-  
rectly influence trade decisions (Audu; Okorie; Orekoya, 2023). However,  
Costa et al (2023) and Hamid et al (2022) argue that religion can affect  
positively or negatively the trade of certain products, such as cultural  
products (films) and food.  
New investigations further underscore how religious, cultural  
and economic factors shape trade patterns. Applying a gravity model to  
Indonesia’s seafood exports, Herianingrum et al. (2024) highlight how  
GDP and common language can strengthen export performance and  
bolster the Halal market. Meanwhile, Muchtar et al (2025) employ a com-  
putable general equilibrium approach to show that free trade agreements  
11  
estudos internacionais • Belo Horizonte, ISSN 2317-773X, v. 13, n. 2, (jun. 2025), p. 9-33  
with countries members of the Organization of Islamic Cooperation  
(OIC) can boost welfare and real GDP for Indonesia’s halal food sector,  
though some product segments may face export declines.  
From a different angle, Zhang; Saghaian; Reed (2023) use a stochas-  
tic frontier gravity model to analyze U.S. bourbon whisky exports, de-  
monstrating that economic size, common language, and policy measures  
can promote trade, again indicating how specialized product attributes,  
religious or otherwise, interact with classical trade drivers. Within the  
European Union, Zaninovi (2025) further confirms that factor producti-  
vity, resource endowments and the ability to meet evolving standards are  
key determinants of agricultural trade flows. These more recent studies  
show that production attributes (e.g., Halal compliance, resource use and  
geographical indication) intertwine with broader economic variables to  
shape the contours of trade, reinforcing the importance of analyzing reli-  
gious and cultural distance alongside conventional drivers.  
This study adopts an agnostic stance regarding religion’s role in  
beef trade, recognizing that cultural factors can both facilitate and hin-  
der commercial flows. Religion may reduce transaction costs by fostering  
trust among members sharing religious traditions, while religious diffe-  
rences can create exclusionary practices that function as trade barriers  
(Lewer; Van Den Berg, 2007; Lee; Park, 2016).  
This analysis contributes to International Relations by examining  
how informal institutions shape trade patterns beyond formal agree-  
ments and tariffs. While traditional international trade literature focuses  
on state policies and formal arrangements, this study addresses how cul-  
tural norms influence economic decisions between states, enriching un-  
derstanding of how identity factors affect countries’ integration into the  
global economy. Based on expansion opportunities in this market seg-  
ment and different possibilities of trade effects (positive, negative, or non-  
-significant), the question arises: what is the effect of religious distance on  
global beef trade? This study evaluates, through a statistical model, the  
effect of religious asymmetry on beef trade flows between 2000 and 2021.  
2 THEORETICAL FRAMEWORK  
2.1 Religious institutions in international relations  
International relations theory provides some frameworks for un-  
derstanding how cultural factors influence interstate economic beha-  
vior. Liberal institutionalism suggests that shared norms and values re-  
duce transaction costs in international cooperation by creating predic-  
table behavioral patterns and common standards (Keohane; Nye, 2011).  
Constructivist approaches emphasize how cultural identities shape state  
preferences and interests beyond material calculations, arguing that ac-  
tors’ understanding of their interests is socially constructed through cul-  
tural practices and shared meanings (Wendt, 1999).  
Religious institutions operate within these theoretical framewor-  
ks as informal constraints that create both opportunities for cooperation  
12  
Michelle Márcia Viana Martins Effects of religious heterogeneity on global beef trade  
and potential conflicts in trade relations. Unlike formal institutions such  
as trade agreements or international organizations, religious norms are  
embedded in social practices and cultural traditions that persist across  
political changes, making them stable but potentially rigid factors in in-  
ternational economic relations.  
When religious backgrounds align between trading partners, facili-  
tative mechanisms emerge. Shared religious practices establish common  
products, production, and business conduct expectations, reducing the  
need for strict monitoring and verification procedures. Religious networ-  
ks provide information channels about market conditions and regulatory  
requirements that complement formal commercial information systems.  
Additionally, transnational religious communities maintain social capital  
that enables reputation-based contract enforcement, reducing dependen-  
ce on formal legal mechanisms for dispute resolution.  
The diaspora literature offers perspectives into these dynamics.  
Graham (2014) demonstrates how ethnic and religious networks reduce  
information asymmetries in international trade, while Cruz (2013) shows  
that diaspora connections help overcome formal trade barriers through  
relationship networks. This is because these communities sustain shared  
norms, repeated interactions, and reputational mechanisms that lower  
transaction costs and improve information flow. Religious communities  
function similarly, creating bridges between geographically separated  
markets through shared cultural understanding and trust.  
However, religious differences can generate exclusionary practices  
that function as non-tariff barriers. Religious dietary restrictions create  
market segmentation requiring specialized certification procedures, se-  
parate supply chains, and costly production adaptations. This segmen-  
tation can exclude countries lacking appropriate religious or conformity  
infrastructure while providing preferential access to those with establi-  
shed certification systems.  
The dual nature of religious influence reflects broader dynamics  
between cultural preservation and economic integration in the interna-  
tional political economy. States must balance domestic religious consti-  
tuencies’ demands for cultural authenticity with international market ac-  
cess requirements, creating policy choices that extend beyond traditional  
economic considerations.  
2.2 Transaction costs and institutional economics  
Classical international trade theories, which focus on productivity  
and factor endowment, did not initially highlight trade costs. However,  
Anderson and van Wincoop (2004) observe that, as trade expands, tran-  
saction costs may surpass transportation costs and tariffs. These transac-  
tion costs encompass all stages of international business, from negotia-  
tions to final delivery (Maragno; Kalatziz; Paulillo, 2006).  
Transaction Cost Theory (TCT) underscores key assumptions  
such as bounded rationality, which refers to limited decision-ma-  
king capacity; uncertainty, which addresses information asymmetry;  
opportunism, which involves exploiting these asymmetries; and asset  
13  
estudos internacionais • Belo Horizonte, ISSN 2317-773X, v. 13, n. 2, (jun. 2025), p. 9-33  
specificity, which concerns exclusive features in transactions (DallAzen;  
Weise, 2014). Economic agents, mindful of these costs, choose gover-  
nance structures that minimize them (Mendes; Figueiredo; Michels,  
2008). In this regard, institutions arise as governance solutions for pro-  
duction and trade (Dasilva-Glasgow, 2020; Cabarello; Soto-Oñate, 2016;  
Acemoglu; Antràs; Helpman, 2007), establishing norms and mechanis-  
ms that reduce risks and foster trust (DallAzen; Weise, 2014).  
North (1993) defines institutions as the “rules of the game” that  
direct economic behavior, whether formal (laws, regulations, con-  
tracts) or informal (traditions, customs, religion). When informal prac-  
tices become formalized, they promote predictable market behavior  
(DallAzen; Weise, 2014; Mendes; Figueiredo; Michels, 2008). Consistent  
with New Institutional Economics, these rules reduce uncertainty, tran-  
saction costs, and opportunities for fraud (Bueno, 2004). By implemen-  
ting regulations, institutions encourage trust and cooperation, limiting  
deceptive conduct and enhancing transparency (Mendes; Figueiredo;  
Michels, 2008). Religion, as an informal institution, shapes norms re-  
garding acceptable meat products, slaughter practices, and labeling,  
thus influencing supply and demand in the meat trade. Importers’ qua-  
lity requirements reinforce consumer confidence in suppliers (Thomé;  
Reis; Paiva, 2003).  
Yet, if producers fail to meet certain religious guidelines, they  
may face barriers in entering specific markets (DallAzen; Weise, 2014).  
Studies indicate that shared religious culture can strengthen bilateral  
trade by reducing transaction costs (Lewer; Van Den Berg, 2007; Bonne;  
Vermeir; Verbeke, 2008; Lee; Park, 2016; Irshad et al, 2018), fostering trust  
and minimizing the need for costly adaptations (Czelusniak; Ribeiro;  
Dergin, 2018).  
Conversely, divergent cultural norms can act like tariffs (Lee; Park,  
2016). Meeting religious requirements often entails additional invest-  
ments in specialized slaughter procedures, certifications, or training, all  
of which can limit access to specific markets (DallAzen; Weise, 2014).  
Similarly, cultural factors such as language, colonial heritage, labor re-  
lations, and religion tend to remain unchanged over time, reinforcing  
consumption patterns and challenging exporters’ efforts to reach certain  
markets (Lopez; Gama, 2010).  
As a result, the historical, religious, and institutional characteristics  
of each region influence trade patterns. When religions and cultural cus-  
toms differ, mistrust generally increases transaction costs and constrains  
bilateral trade. Therefore, the economic burden associated with reduced  
trade flows can become relevant for key markets.. In light of this, it is  
important to examine cultural aspects, particularly religion, as a possib-  
le determinant of export performance. This consideration is vital in the  
meat industry, which faces strict regulations and anticipates growth in  
both consumption and numbers of Jewish and Muslim consumers. The  
following section explains the methodology employed in this study.

3 METHODOLOGY  
3.1 Theoretical gravity model  
Tinbergen (1962) was the first to propose a gravity model to ex-  
plain international trade flows, suggesting that trade volume between  
countries is influenced by their economic size and the distance between  
them. His model laid the groundwork for quantifying deviations bet-  
ween observed and expected trade in the absence of barriers. However,  
despite its empirical success, the gravity model lacked a solid theoretical  
foundation for decades. This gap was addressed by Anderson and van  
Wincoop (2003), who developed a micro-founded version of the gravity  
model based on a constant elasticity of substitution (CES) utility function  
and market-clearing conditions. Their framework provided the necessary  
theoretical consistency, enabling more accurate estimations of bilateral  
trade flows, following the 1 equation:  
where the variable is the exports of product from country to im-  
porter in year; is the expenditures of country on products in year; and  
are, respectively, the quantity of produced in country and the aggregate  
international production of such products in the world, in; and are multi-  
lateral resistance terms of trade in; is the elasticity of substitution among  
products, represent the bilateral trade costs betweenand countries in year  
for product.  
The major contribution of Anderson and van Wincoop (2003) was  
the consolidation of the multilateral resistance terms. The variables and  
were formally defined to show that bilateral trade flows are influenced  
not only by the trade costs between two countries but also by costs in-  
curred with other trading partners. In other words, trade between coun-  
tries i and j is affected not only by their direct costs but also by the costs  
between country j and a third country. Mathematically, these indices are  
represented by the following equations:  
represents external multilateral resistance, indicating that exports  
from country i to country j depend on the trade costs between country j  
and all potential export markets. denotes internal multilateral resistance  
and reflects how country j imports depend on trade costs with all possible  
supplier countries for products k. The inclusion of these terms marked an  
advancement in the gravity model, allowing for more accurate estimates.  
According to Carneiro et al (2022), omitting these terms is a major econo-  
metric issue that leads to biased estimates due to omitted variable bias. A  
15

common method to address this issue involves using fixed effects, which  
account for any variables representing potential trade frictions.  
is a function of all bilateral barriers that affect trade. Literature of-  
ten approximates this using a set of variables representing costs, which  
may be geographic or historical-institutional, such as distance, conti-  
guity, common language, cultural ties, or religious differences. Also, it  
can incorporate measures of trade policy, including tariffs and non-tariff  
barriers.  
Building on this theoretical development, the gravity model has  
become a widely used tool in empirical studies involving trade volumes.  
Given that trade flows are a key element in economic relations and the  
necessary data for estimating the model is easily accessible, many studies  
have adopted the gravity model, solidifying it as one of the most utilized  
methods in the field of international economics (Baldwin; Taglioni, 2006;  
Carneiro et al, 2022).  
The evolution of the model, as well as improvements in estimation  
techniques, as discussed by Yotov et al (2016), has enabled the use of gra-  
vity equations to contrast the influence of trade preferences against other  
determinants of trade, such as distance between countries, income levels,  
language, borders, trade agreements, religion, among others Anderson;  
Larch; Yotov (2020), Carneiro et al (2022) and Costa et al (2023) employed  
the gravity model approach to estimate trade determinants.  
3.2 Empirical model  
The analysis of the relationship between beef exports and bilate-  
2
ral religious disparity covered the years 2000 to 2021 . The trade flow  
occurred between 21 major beef exporters and 164 trading partners, re-  
presenting 95% of the global exports of the product during this period.  
The selection of exporters was based on countries responsible for 95% of  
global beef imports, similar to the methodology employed by Peci and  
Sanjuan (2020), who identified 40 importing countries that accounted for  
80% of global pork imports.  
The estimates utilized a panel data framework, analyzing infor-  
mation from individuals (countries) across several time points. This data  
structure improves estimator efficiency and parameter inference accu-  
racy, as panel data offers increased degrees of freedom (Hsiao, 2005).  
Various beef products were incorporated into the panel alongside the na-  
tion and year measurements. The products were categorized at the six-di-  
git level following the Harmonized Commodity Description and Coding  
3
System (HS).  
The model is estimated to be using the Poisson Pseudo-Maximum  
Likelihood (PPML) estimator, which is appropriate for analyzing trade  
flows as it addresses the issue of bilateral flows equal to zero in dependent  
2. The period from 2000 to 2021 was selected due to the availability of consistent and standardized data,  
enabling long-term analysis of cyclical and structural patterns in beef trade. More recent data remain under  
revision, making this time frame the most reliable for cross-country comparisons.

(fresh/frozen) and edible offal (tongue, liver, etc.), encompassing whole carcasses or bone-in/boneless portions.

variable, indicating the absence of trade for certain country pairs, year  
and the product, or data missing. Around 94% of the sample contains  
zero or missing data. The PPML surpasses the Ordinary Least Squares  
(OLS) estimator, omitting observations with zero trade flows, resulting  
in selection bias and the loss of significant information from null flows.  
Besides addressing this issue, the PPML can estimate the model despite  
the heteroscedasticity (Santos Silva; Tenreyro, 2006). The functional spe-  
cification for the estimated equation is articulated as:

Where represents beef imports from to importing countries of in  
year; is the constant;, are fixed effects of exporter-year-product and im-  
porter-year-product; is an index variable; is the bilateral distance between  
countries of origin and destination, a proxy for transportation costs; is a  
dummy that takes the value 1 if and countries share a common border  
and 0 otherwise; is a dummy that takes the value 1 if and countries have  
a trade agreement in year and 0 otherwise; is a dummy indicating colo-  
nial ties between countries, with value 1 if there are colonial ties and 0  
otherwise; is a dummy indicating whether the countries have the same  
official language, assuming value equal to 1 if so and 0 otherwise; is the  
error term.  
The Religious Distance variable ( refers to the religious proximity  
index (comrelig) developed by the Centre d’Études Prospectives et d’Infor-  
mations Internationales (CEPII). It is a bilateral similarity measure in built  
from country-level shares of three denominations, Catholic, Protestant,  
and Muslim, sourced from La Porta et al (1999, 2008). Formally, where  
is the share of denomination in country Values near 1 indicate highly  
similar compositions; values near 0 indicate little or no overlap. The va-  
riable is symmetric, time-invariant in CEPII’s Gravity dataset, and cap-  
tures a narrow but tractable dimension of cultural proximity that can  
affect trade by shaping information flows and trust. A limitation is that  
it aggregates only three traditions and omits others, so it should be read  
as a coarse proxy rather than an exhaustive religious landscape (Mayer;  
Zignago, 2011).  
To provide greater robustness to the model, some alternative es-  
timations were carried out to verify whether the effect of the religious  
variable remains. Firstly, the estimations were categorized by product  
5
type: chilled beef, frozen beef and offal . This distinction is interesting  
because the trade of offal may be influenced by cultural factors, such  
as the prohibition against consuming residues and blood in Jewish and  
4. Although the analysis is based on export data, import data is used for reliability. Customs authorities have  
greater control over import data because it is on this data that customs duties are levied.  
5. Chilled beef is fresh meat preserved at 0-4°C with limited shelf life, requiring fast transportation and  
serving premium markets. Frozen beef has extended shelf life enabling long-distance trade and representing  
53.5% of beef trade during the analyzed period. Offal includes organ meats and by-products that face distinct  
religious restrictions, as certain traditions prohibit consumption of blood-containing organs, making this  
category potentially more sensitive to religious differences between trading partners.  
17  
estudos internacionais • Belo Horizonte, ISSN 2317-773X, v. 13, n. 2, (jun. 2025), p. 9-33  
Muslim religions. Additionally, there is a distinction for chilled pro-  
ducts, as their trade is less frequent than that of frozen beef due to their  
perishability and the transportation costs associated with maintaining  
refrigeration. These categories may respond differently to religious dis-  
tance because frozen beef dominates trade volumes where cultural trust  
matters more, while religious similarity may actually reduce offal trade  
when shared dietary restrictions prohibit organ meat consumption.  
The second robustness strategy was to control the main exporters  
of Halal and Kosher-certified meat. To this, a dummy variable was im-  
6
plemented for the principal global exporters of these products in 2022 ()  
(Equation 5), and an interaction between this variable and religion was  
analyzed (Equation 6). Also, there was an interaction between this varia-  
ble and the religion variable to analyze (Equation 6). Religious slaughter  
involves costs associated with modifying manufacturing techniques. If  
these countries maintain access to consumer markets, it indicates that  
they have not only borne these costs but also remained competitive in  
international markets.  
Still to test the robustness of the estimates, the population of each  
exporter allocated across various religions was included in the model.  
The latest data for this information is from 2010 and was applied to all  
years of the panel as a proxy for religious representation. While the num-  
ber of devotees may fluctuate over time, no significant variation in the  
proportion of adherents to religions is expected. Consequently, utilizing  
lagged data is not anticipated to pose an issue.  
, refer to the number of individuals in the exporting country (i)  
who adhered to Christianity, Judaism and Islam (Muslims) in 2010, res-  
pectively. To estimate these variables, exporter-year-product fixed effects  
were removed because their inclusion would lead to the omission of tho-  
se variables due to multicollinearity. Importer-year-product fixed effects  
were maintained.  
Another strategy to test the robustness of the results is to insert the  
importer and exporter Gross Domestic Product [GDP] on the gravity mo-  
del, replacing the time-varying unilateral fixed effects, which are replaced  
by fixed effects of importer, exporter, year and product (Capoani; Barlese,  
2021; Nijkamp; Ratajczak, 2021; Ribeiro et al, 2019). The GDP variables  
are proxies for the importer’s demand capacity and the exporter’s supply  
capacity, respectively.  
6. This data is a proxy for the largest exporters between 2001 and 2021. No time series were found to indicate  
which countries held the largest market shares for these goods. However, the inclusion of this variable allows  
us to associate the largest suppliers of beef with a comparative advantage in exports of meat with religious  
certificates.

and represent the GDP of the exporter and the importer in year,  
respectively. Both variables were absorbed in equation (4) by the fixed  
effects importer-year-product and exporter-year-product.  
The religion variable did not change for the evaluated years, as it  
varies only between countries. For this reason, bilateral fixed effects to  
country pairs are not included, as their inclusion would omit the variable  
of interest due to multicollinearity issues. The use of time-varying uni-  
lateral fixed effects (importer-year, exporter-year) controls multilateral  
resistance terms in the theoretical model (Feenstra, 2015; Head; Mayer,  
2014). Fally (2015) notes that estimates containing these fixed effects cor-  
respond to the structural gravity terms, which differ from the traditional  
gravity model. In the structural model, the time-varying unilateral fi-  
xed effects determine the expenditures and output adjusted to the actual  
values of production and expenditures, represented as and in the theore-  
tical model.  
One particularly useful feature of the structural gravity model for  
empirical applications is its separability, allowing it to be applied to dif-  
ferent product categories. This enables the study of bilateral flows for a  
specific product independently. Consequently, the unilateral fixed effects  
become importer-time-product and exporter-time-product fixed effects  
(Carneiro et al., 2022). Secondly, from a practical perspective, adding fixed  
effects ensures a consistent consideration of bilateral trade costs, which  
can be achieved in three simple steps: (i) estimating the gravity equa-  
tion using PPML; (ii) constructing bilateral trade costs for each country  
pair, which this study did not address due to multicollinearity issues with  
the variable of interest; and (iii) aggregating bilateral trade costs at the  
desired level using the estimates of importer and exporter fixed effects  
(Yotov; Piemartini, 2016).  
To address step (ii), standard variables commonly used in gravity  
models were included. Anderson and van Wincoop (2003) highlight tra-  
ditional variables used as proxies for costs in gravity models, such as bi-  
lateral distance, shared borders, language, and colonial ties—factors that  
represent time-invariant bilateral costs. Additionally, Yotov et al (2016)  
recommend estimating the gravity model with spaced intervals, sugges-  
ting gaps of 3 to 5 years to capture adjustments in trade flows to trade  
policies. However, since this study does not aim to evaluate trade policies  
such as tariffs or non-tariff measures, the model was estimated without  
incorporating time gaps.

4 RESULTS  
Before presenting the econometric results, Figure 1 presents infor-  
mation about the international beef market from 2000 to 2021, indicating  
the largest producers, importers, exporters, and consumers. The U.S. is  
the largest beef producer worldwide, with a cumulative production of  
275,052 thousand metric tons (MT), underscoring its pivotal position in  
the global supply chain. Brazil (207,593 thousand MT) and the European  
Union (EU) (176,897 thousand MT) are the next largest producers. Brazil,  
with its vast agricultural land and favorable conditions for livestock far-  
ming, stands out as the leading producer in Latin America, while China  
and India are the major producers in Asia, accounting for 140,121 thou-  
sand MT and 72,949 thousand MT, respectively. Despite being the largest  
producer, the U.S. is also the top importer of beef, with 30,966 thousand  
MT of imports over the period, highlighting strong domestic demand.  
China, driven by rapid economic growth and shifting consumption pat-  
terns, imported 16,183 thousand MT. Other key markets include Japan  
(17,385 thousand MT) and the European Union (10,463 thousand MT),  
reflecting the global appetite for beef in both developed and expanding

Estimates7.  
On the export side, Brazil leads with 39,318 thousand MT of beef  
exported, consolidating its position as one of the world’s major suppliers.  
Australia (32,580 thousand MT), the U.S. (24,429 thousand MT), and  
India (24,844 thousand MT) also stand out as key suppliers to internatio-  
nal markets. Domestic consumption trends reflect production and im-  
port patterns. The U.S., with total consumption of 281,449 thousand MT,  
leads the world in beef consumption, highlighting the role of domestic  
demand in influencing the global market. Brazil, with 169,451 thousand  
MT, and China, with 155,285 thousand MT, respectively, also emerge as  
consumers.  
The data indicates that a few key players largely dominate the glo-  
bal beef trade. The U.S., Brazil, China, and the EU are major actors in  
both production and consumption, while Brazil, Australia, and India lead  
as top exporters. The growing demand in Asian markets, especially in  
China and Japan, suggests a shift in global consumption trends that were  
previously more concentrated in the U.S. and EU, with beef becoming a  
more important part of diets in these regions.

The territorial distribution of the Christian, Muslim, and Jewish  
religions is presented in Figure 2. Predominantly Christian countries are  
located in the Americas, Europe, southern Africa, and Oceania. Muslim  
populations are primarily concentrated in northern Africa, the Middle  
East, and parts of Asia. Israel is the country with the largest Jewish po-  
pulation, holding 75.6% of the world’s Jewish population (Pew Research  
Center, 2024). The primary exporters of beef are predominantly Christian  
countries.

Table 2 presents the descriptive analysis of the variables. The reli-  
gious index measures religious similarity between country pairs, whe-  
re values equal to or closer to 0 indicate lower religious similarity, and  
values closer to 1 represent greater similarity in the religions of the po-  
pulations of two countries. The mean value of 0.204103 suggests that, on  
average, religious similarity between country pairs is low, indicating dif-  
ferences in religious practices among most pairs. The standard deviation  
of 0.261002 reflects considerable variation in the data, indicating a wide  
variation in similarity among countries. The minimum value of 0 indica-  
tes that some country pairs have no religious similarity at all, while the  
maximum value of 0.960284 suggests that the most similar country pair  
shares 96% religious proximity.

Based on descriptive analyses and the observation that some of the  
main importers consider the religious aspect as a determinant of beef  
consumption, this study estimates the average effect of religious simi-  
larity on trade volume. The econometric results are presented in Table  
3, with each column representing the results of a different econometric  
equation.

the absence of bilateral trade for the country-sector-year pair combination.  
For total beef exports, the variable wasn’t statistically significant in  
trade across all regressions, except in 2 column. Various functional forms  
were employed to test the robustness of the effects of religious distance  
on trade flows, and in almost all estimations, beef trade wasn’t affected  
by religious heterogeneity between parties. This finding is consistent  
with Iannaccone (1998) and Audu; Okorie; Orekoya (2023), who suggest  
that there is no relationship between religion and economic activity.  
Furthermore, the sample includes all types of meat, and there may be  
hidden heterogeneity among the beef modality heterogeneity that affects  
the average results.  
Since the sample of countries considered in the study is quite he-  
terogeneous, it is important to highlight specific characteristics of the  
exporters. When the analysis incorporates the dummy (column 2), it con-  
trols for the main exporting countries of Islamic and Jewish products. In  
this case, religion has a positive and significant effect on trade flows, that  
is, the impact of religious symmetry on trade when the main exporters  
of Halal and Kosher certified meat are not considered. When isolating  
from estimates, countries with appropriate certifications to foster trust  
among Halal and Kosher meat consumers, the religious proximity posi-  
tively affects trade flows, suggesting that the greater the religious simi-  
larity, the higher the trade flows are likely to be. On the other hand, the  
interaction term (column 3) reinforces the previous finding that, for the  
24  
Michelle Márcia Viana Martins Effects of religious heterogeneity on global beef trade  
main exporters of meat subject to religious requirements, does not have  
significant trade effects.  
To understand the effect of religion on beef trade, columns 4, 6, 7,  
and 8 include the proportion of religious people from different religions  
in the exporter country population in the estimations. In all cases, con-  
sidering the religious population did not alter the non-significant effect  
of religious symmetry between country pairs on trade volume. To test  
the robustness of these estimates, the fixed effects for exporter-year-pro-  
duct were removed. Without any additional control variables, the results  
indicate that the number of Christians in the exporting country has no  
statistically significant relationship with trade. However, the larger the  
Jewish population in the exporting country, the stronger the positive re-  
lationship with beef exports, while the larger the Muslim population, the  
more negative the relationship with beef trade.  
The results are robust when controls for the economic size of the  
countries are added, which includes the importer and exporter GDP (co-  
lumn 6), the dummy variable (column 7), and the interaction term (co-  
lumn 8). In the inclusion of these last variables, the Christian population,  
represented by ln, showed a negative statistical relationship with trade  
flows, suggesting that the larger the Christian population in the expor-  
ting country, the lower trade. In 8 column, populations were re-estimated  
one by one. In this case, the relationship between the Christian popula-  
tion and trade remained non-significant, while the Jewish population (p  
< 0.01) and Muslim population (p < 0.001) maintained their significance  
and sign.  
The population size can have two distinct interpretations concer-  
ning trade in the context of religious differences. First, when most of a  
country’s population follows religions different from those in another  
country, this may lead to a reduction in trade transactions due to the  
religious requirements imposed by consumers in importing countries,  
which limits meat exports from countries with religiously distinct po-  
pulations. A second explanation concerns countries with predominantly  
religious populations that follow traditional practices. In such markets,  
much of the meat produced is likely for domestic consumption or trade  
with countries sharing similar religions. This argument is supported by  
Irshad et al (2018), who suggest that countries with similar religions tend  
to engage in more trade with one another.  
The positive coefficient for Jewish populations may reflect the con-  
centration of Jewish communities in developed countries with advanced  
meat processing capabilities and established export networks. Jewish  
dietary laws (Kosher) require extensive supervision and certification  
infrastructure, which may signal higher quality standards that benefit  
overall meat exports beyond religious markets. Conversely, the negative  
coefficient for Muslim populations may reflect supply-side constraints in  
countries with large Muslim populations. Many Muslim-majority coun-  
tries may prioritize domestic consumption or have production systems  
less oriented toward international export markets. Additionally, Halal  
certification requirements may involve different production adaptations  
that create trade-offs between serving domestic religious populations and  
25  
estudos internacionais • Belo Horizonte, ISSN 2317-773X, v. 13, n. 2, (jun. 2025), p. 9-33  
competing in broader international markets.  
The expectation that religion might matter in beef markets stems  
from the dominance of Christian-majority countries as major exporters,  
which creates an apparent puzzle. If comparative advantage based on  
land endowments and production costs primarily determines beef export  
patterns, religious factors should be irrelevant. However, the presence  
of religious minorities within exporting countries may create speciali-  
zed production capacities that serve global religious markets. Countries  
like Australia and Brazil, while predominantly Christian, have developed  
Halal and Kosher certification infrastructure that enables access to rapi-  
dly growing Muslim and Jewish consumer populations, suggesting that  
religious considerations operate alongside rather than against traditional  
comparative advantage factors.  
The analysis for disaggregated products (Table 4) shows that frozen  
meat trade (column 2) and offal (column 9) are significantly influenced by  
the variable in some particular cases. Religious proximity between coun-  
try pairs indicates a positive relationship with trade flows for frozen meat  
and a negative relationship for offal.

In the frozen meat trade, the significant results occur only in the  
general model, the results are not consistent with the inclusion of the va-  
riable, the interaction term (column 5), and the proportion of adherents  
to religions variables (column 8). For offal beef, the results were only sig-  
nificant when the controls, the interaction term, and the religious sha-  
re were included. Sharing religious norms reduces compliance costs and  
increases competitiveness for exporters with similar traditions as their  
trading partners. Stronger cultural and social ties facilitate trade and the  
formation of partnerships. These ties establish a greater degree of trust  
and mutual compliance in meat production and trade practices, easing  
trade transactions between partners. The frozen beef trade was particu-  
larly affected because transactions in this type of meat are more frequent  
than in other categories. Of the beef trade during the investigated period,  
53.5% was frozen, 36.3% was chilled meat, and 10.2% was offal.  
Countries with similar traditions tend to have similar food prefe-  
rences. Some religions impose specific dietary restrictions that prohibit  
the consumption of certain foods, such as offal, which may be considered  
impure or associated with specific ritual practices. Therefore, countries  
with similar religious traditions are negatively correlated with the trade  
of this type of meat, as they avoid consuming offal to prevent impurity  
and demonstrate religious respect.  
The variable was positive and significant in regressions (8) and (9) for  
frozen meat and offal, respectively. This dummy variable represents the  
largest exporters of Halal and Kosher meat and reflects the characteristics  
27  
estudos internacionais • Belo Horizonte, ISSN 2317-773X, v. 13, n. 2, (jun. 2025), p. 9-33  
and competitive advantages of these countries, making them more likely  
to engage in large-scale trade transactions for meats that meet religious  
requirements.  
For the other variables, the trade elasticity of distance, represented  
by the estimated logarithmic variable, is negative and statistically signi-  
ficant, demonstrating its relevance as a trade resistance factor. More spe-  
cifically, distance serves as a proxy for transportation costs, which may  
involve the need for specialized transportation, such as refrigerated con-  
tainers, increasing logistical expenses over longer distances. This result  
aligns with Gani (2021), who argues that a 1% increase in the distance  
between a pair of countries causes a 0.71% decline in trade between them.  
The binary variable measuring the colonial relationship between  
countries is not significant. This finding is consistent with Bampi; Zago  
de Azevedo; dos Reis (2020), who argue that global integration and the  
evolution of trade have made colonial trade relations irrelevant. Similarly,  
the coefficient for contiguity is also not significant. Junior, Massuquetti;  
Azevedo (2017) suggest that the establishment of trade agreements can  
enhance logistical development through the incorporation of transport  
technology, and therefore, sharing a common border may indeed be in-  
significant in explaining trade.  
The language variable reveals statistical significance and a positive  
coefficient, indicating the advantage that a common language provides  
in increasing trade levels (Majeed et al, 2019). A common language fa-  
cilitates communication and negotiation, reducing the language barrier  
and associated costs of translating packaging and labels. Moreover, it can  
also serve as a cultural link between countries that speak the same native  
language.  
Membership in trade agreements, represented by the RTA variable,  
shows statistical significance with a positive effect on trade flows. Trade  
agreements facilitate trade between countries by establishing common  
terms and implementing less restrictive tariff policies. Majeed et al (2019),  
citing the case of Halal markets, discuss how commercial gains could be  
achieved if countries with similar cultural backgrounds developed a con-  
solidated beef market, including a common certification body for Halal  
products. Such preferential agreements could enhance trade between re-  
ligious countries while potentially limiting trade opportunities for non-  
-member markets.  
The GDP of importers and exporters countries also exhibited sig-  
nificance with positive parameters. The exporter’s GDP indicates produc-  
tion capacity, while the importer’s GDP reflects consumption capacity.  
In the context of trade influenced by religious considerations, exporting  
countries must adapt their production and marketing strategies to meet  
the cultural demands of the importing countries. These importers are  
expected to pay a premium for meat produced under religious certifica-  
tion. This aligns with the predictions of the gravity model, as noted by  
Gani (2021).

5 FINAL CONSIDERATIONS  
Although the global beef trade is concentrated among a few expor-  
ting countries, the question arose whether this trade could be influenced  
by religion as a cultural factor. Some studies have demonstrated that sha-  
red religious beliefs favor shipments from economies with similar reli-  
gious practices. To broaden the analysis, this study investigated whether  
this effect persisted across a larger sample that included all beef-impor-  
ting countries.  
The expansion of global supply chains and the increase in inter-  
national shipments require countries to adapt to the demands of foreign  
markets. In the beef sector, this involves navigating a complex industry  
where slaughtering and processing practices are often dictated by reli-  
gious specifications. Emphasizing the religious aspect underscores the  
need to examine the various barriers to exports, as trade with speciali-  
zed markets necessitates suppliers adapt their practices and obtain the  
appropriate certifications. This study explored beef exports through the  
lens of different religious beliefs, focusing on the stringent requirements  
imposed by Halal and Kosher consumer markets.  
The results show that bilateral beef trade is influenced by factors  
such as distance, importer and exporter income, common language, and  
trade agreements. However, no statistically significant relationships were  
found between religion and trade flows in the analysis that includes all  
types of beef, particularly without specific controls for major Halal and  
Kosher beef exporters. This result indicates that, for a broader group of  
countries, not just those with specific religious requirements, cultural va-  
riables were not a determinant of trade. This finding could be consistent  
with two key arguments: First, not all countries strictly enforce laws on  
beef slaughter based on religious beliefs like those of Islam and Judaism.  
While these religions profoundly influence the culture and lifestyles of  
their followers, affecting their dietary patterns. Second, the institutions  
in exporting countries may be sufficiently adapted to minimize transac-  
tion costs related to religious slaughter requirements.  
However, when controlling for the major exporters of Halal- and  
Kosher-certified beef, religion emerges as a factor in determining the beef  
trade. The statistical significance of religion variable indicates that reli-  
gious similarity between countries influences animal protein shipments.  
Nevertheless, countries that do not share similar religious practices with  
their trading partners can still establish successful international nego-  
tiations by understanding the institutions that shape market behavior,  
including cultural customs, laws, and religious considerations of the im-  
porting country.  
The results suggest that trade effects operate primarily through  
religious population composition in exporting countries rather than bila-  
teral religious distance per se. The significant coefficients for Jewish and  
Muslim population shares, combined with the generally non-significant  
religious distance variable, indicate that domestic religious demogra-  
phics matter more for export performance than cultural similarity with  
trading partners. This pattern suggests that religious minorities within  
29  
estudos internacionais • Belo Horizonte, ISSN 2317-773X, v. 13, n. 2, (jun. 2025), p. 9-33  
exporting countries may drive specialized production capabilities that  
serve global markets, rather than religious proximity facilitating trade  
through reduced transaction costs between similar countries.  
Religious culture can influence the international beef trade in se-  
veral ways, as it shapes dietary preferences and consumption practices  
regarding animal protein. Specifically, religion plays a relevant role in  
determining beef imports for predominantly Islamic or Jewish countries  
in their trade with the global market. The procedures required for Halal  
and Kosher certification exemplify the specific standards that beef must  
meet to enter these markets.
