An extant body of literature covering both intra- and inter-country settings has shown that trade openness tends to accelerate economic growth (see, among others, Yanikkaya, 2003; Manole & Spatareanu, 2010 ). While various socioeconomic and political determinants have been shown to moderate the dynamic long-term effects of openness on growth, countries’ affine nature in religiosity could be a potential driver of growth and openness relationships. In particular, one may ask, does the persistence of certain types of religious beliefs shape growth and trade-openness relationships? In earlier work, Barro and McCleary (2003) and Durlauf et al. (2012) have explored the macroeconomic effects of religious beliefs on aggregate economic outcomes. Moreover, Barro and McCleary (2003) have identified the two dimensions of religion, i.e., religious beliefs and participation in religious activities. The key findings from their study indicate that some aspects of religious beliefs positively correlated with economic growth, while religious activities measured through participation in church attendance negatively correlated with economic growth. Besides, they also suggest that higher levels of church attendance depress economic growth because attendance in the church could use a larger share of resources by the religious sector, while fewer resources could be used for the primary output sector. Therefore, they find a reverse relationship between religious belief and economic growth, indicating that less attendance in church generates more output and facilitates the economy to grow faster.

Previous literature examined the relationship between religious affiliations and economic growth in the context of economic growth determinants. For instance, Fernandez et al. (2001) find that Confucianism is one of the most determinants of economic growth. Moreover, they find that any historical or cultural explanations which are not necessarily related to religion have a heterogeneous impact on growth experiences. Nevertheless, Barro and McCleary’s (2003) findings that religion matters for economic growth are an important insight which lies outside the domain of the canonical neoclassical model. Several scholars have given importance to various parameters for economic growth. The well-known works in this line of thought include Sachs (2003) , finding that economic growth and other economic and demographic dimensions strongly correlate with geographical and ecological variables. Other prominent scholars also explain several valuable factors in cross-country differences, including Institutions (Acemoglu et al., 2001, 2002; Acemoglu & Johnson, 2005) and ethnic heterogeneity (Easterly & Levine, 1997; Alesina et al., 2003) . The neoclassical models explained by several prominent scholars prove that religion has a specific role in economic growth, which represents the beginning of a new research direction in international economics, incorporating the growth models.

Nevertheless, in a related work focusing on nations’ cultural characteristics, Inglehart and Baker (2000) and Deneulin and Rakodi (2011) argue that nations’ culture determines the movement of economic growth. However, in these and similar studies, a cultural dimension is envisaged in the form of honesty and work ethics, among others. Religion is one of the critical dimensions of a country’s culture. This can influence the extent of “trade dynamics” by controlling the type of import and export (reflecting religion-driven taste and preferences). Therefore, this paper investigates religion’s role in the growth and trade-openness relationship. North (1990) argues that informal institutions’ religious freedom, customs, ideology, and code of conduct have essential growth consequences in earlier work.

Similarly, previous studies like Woodberry (2012) argue that religious freedom, like modernity, has played a significant role in developing financial and political institutions leading to changes in growth dynamics in a country. More recently, the empirical work by Rasoanomenjanahary et al. (2022) finds that trade openness has an adverse effect on economic growth in Madagascar. Similarly, Oppong-Baah et al. (2022) find that trade openness and the real exchange rate substantially affect economic growth in Ghana and Nigeria. Further, Mallick and Behera (2020) find evidence of asymmetric cointegration between economic growth and trade openness in India during the pre-trade reforms period 1960-1990 and the post-trade reforms period 1991-2018. Goldar et al. (2020) examine the impact of trade liberalization in India during the late 1990s and 2000s on the productivity of manufacturing firms and find that the lowering of output tariff had a more significant impact on the productivity of Indian manufacturing firms than the lowering of tariff on intermediate inputs. Further, Behera (2014) found that after trade liberalisation in India, industries which experienced a decline in the tariff cost exhibited more substantial growth in domestic firms’ productivity.

In our work, we ask a broad question: does religious freedom (have a heterogeneous) effect on economic growth and the trade-openness relationship? We contribute to the literature on economic growth and trade-openness literature by investigating the instrumental role of religious freedom. To explore the religious freedom heterogeneous impact on trade openness-economic growth nexus, we have selected panel data covering 117 countries consisting of developed and developing economies. Besides, following the World Development Indicators database of the World Bank and based on World Bank gross national income (GNI) per capita in current USD, our sample of 117 countries comprises high-income, upper-middle-income, and lower-middle-income countries. A robust empirical assessment of panel data covering 117 countries (comprising high-income, upper-middle-income, and lower-middle-income countries) reveals that religious freedom (like less liberal, moderate liberal, and high liberal) has a significant effect on economic growth-trade openness interdependence. However, the impact of religious freedom on the dynamic nexus between economic growth and trade openness is heterogeneous.¹

Figures 1-4 portray the relationship between religious freedom and economic growth (GDP per capita) across different groups of countries through a scatter-fitted line. Figure 1 explains the relationship between religious freedom and economic growth in the case of a full panel of 117 countries consisting of developed and developing economies. It seems that the relationship between religious freedom and economic growth is positive (see Figure 1). Besides, the fitted line is not highly positive, indicating that highly liberal religious beliefs and practices have a specific impact on economic growth. However, the impact of religious

freedom on economic growth is not substantially more decisive in the case of highly liberal groups of countries (see Figure 1).

Similarly, Figure 2 explains the relationship between religious freedom and economic growth in the case of highly liberal religious groups of countries. The fitted line between freedom of religious faith and practices and countries’ economic growth reveals a positive and upward movement relationship. Therefore, it shows that religious freedom significantly raises economic growth across groups of highly liberal religious countries. Nevertheless, the impact of religious beliefs, faith and practices on economic growth in other groups of countries is contrary to the previously fitted line and estimated results. Results reveal that the effects of religious belief and practices on economic growth are adverse in the case of moderate-liberal group countries (see Figure 3). In contrast, the impact of freedom of religious belief and practices on economic growth is relatively stagnant. Besides, the fitted line seems to be a horizontal straight line across countries with less liberal religious belief and practices (see Figure 4). Therefore, it is pretty inconclusive to arrive at a particular inference that freedom to religious belief and practices has any significant impact on economic growth across the countries with less liberal in religious practices and beliefs.

Descriptive statistics are presented in Table 1. Table 2 shows quantile regression results for the total sample and sub-samples based on religious freedom (less liberal, moderate liberal, and high liberal). We find that the signs and magnitudes of the coefficients of trade openness vary across quantiles. This suggests that higher openness does not necessarily facilitate higher economic growth. More specifically, in the case of a full sample of 117 countries, the estimated coefficients of trade openness are negative and significantly different from zero at the 75th and 90th quantiles (see Columns 1 and 2, Table 2). This suggests that trade openness significantly dampens economic growth in mixed groups of countries, including developed and developing countries. Therefore, results exhibit that trade share as a percentage of GDP (representing trade openness) in certain circumstances during the phase of low financial development and macroeconomic instability dampens the economic growth of developing countries.

Further, the results of other groups of countries following the religious freedom index are quite contrary, and the empirical consequences are inconclusive. Moreover, results exhibit that trade openness significantly enhances economic growth across the less-liberal and moderate-liberal religious beliefs countries. In contrast, empirical results demonstrate that at 90th quantiles, trade openness significantly dampens economic growth across high-liberal religious beliefs and practices groups countries (see Column 8, Table 2). This suggests that high-liberal in religious beliefs and practices does not facilitate economic growth. This is consistent with the findings of Barro and McCleary (2003) , indicating that high-liberal religious beliefs and practices and more extensive participation in church during working hours sometimes become impractical use of public resources, which harms the country’s production and economic growth.

The effects of democratic regimes across most countries are negative and significantly different from zero. However, the coefficients of autocratic regimes in highly liberal religious belief countries are positive and significantly different from zero. This suggests that countries with highly liberal religious beliefs with a highly authoritarian system have higher economic growth.

Notwithstanding, religious belief plays a vital role in economic growth in highly liberal countries. However, religious freedom negatively affects the economic growth of moderately liberal countries. We then account for macroeconomic and specific control variables’ effects on economic growth across different countries. Results reveal that social and political globalization substantially affects the economic growth of the sets of different countries. Further, results indicate that, like social openness, financial globalization is a relevant driver of economic growth across different sub-sets of religious openness countries. Figures 5-7 portray the quantile plot of explanatory variables’ effect on economic growth in groups like less, moderate and high-liberal countries. In the case of less-liberal groups of countries, Figure 5 portrays that the quantile plot of the total population, social globalization, autocratic regimes, and religious freedom positively impact economic growth. The trade openness’s impact on economic growth is pretty downward, which shows a declining trend at an early stage and later, its impact on economic growth is positive. The quantile plot shows economic policy uncertainty and external debt (% GDP), indicating that the financial stability parameters are swinging upwards and downwards, and fluctuating trends and these effects on economic growth fluctuate. In comparison, the quantile plot shows that political globalization and the rate of inflation adversely affect economic growth in the less-liberal religious freedom countries.

Nevertheless, Figure 6 portrays that the effect of HDI, autocratic regimes and religious freedom on economic growth seems negative across moderate-liberal groups in religious beliefs and practices countries. However, the quantile plot shows that the effect of trade openness on economic growth seems positive and has upward trends. This is consistent with the empirical evidence obtained from the quantile regression results. Besides, the quantile plot shows the impact of economic policy uncertainty, social and financial globalization, total population (indicating the market size of a country), and inflation rate oscillating. This suggests that macroeconomic price instability, abrupt changes and uncertainty in

economic policy adversely affect economic growth. This is possible because many emerging markets and developed countries passed through the phase of global financial shocks, oil price shocks, and the east Asian financial crisis during the 1990s and after the 2000s. As the financial markets are interrelated, and to overcome these shocks and to revamp the economy from these shocks, policy planners of many countries have taken unstable policies. Therefore, erratic changes in the economics and financial policies and macroeconomic price instability facilitated an adverse effect on economic growth.

Figure 7 indicates that the quantile plot of trade openness shows a declining and rising trend during the study period. However, the quantile plot of religious freedom, democratic regimes, social and financial globalization, and the inflation rate seems to be declining. This indicates that a high and consistent inflation rate dampens economic growth across high-liberal countries. In contrast, economic policy uncertainty’s effect on economic growth fluctuates. However, it appears to be a positive impact on economic growth across the groups of highly liberal religious beliefs and practices countries. Although the quantile plot shows decreasing trend at an early period, after a certain period, the trend shows rising, indicating that economic policy uncertainty even positively affects economic growth.

Across quantiles and for all countries, financial sector stability measured by the external debt coefficients is negative and significantly different from zero. Therefore, this result complies with the argument that greater financial instability would decrease countries’ economic growth. Alternatively, as we discussed before, we re-estimate the empirical model using the MM-QR technique to avoid endogeneity bias. The MM-QR estimated results are reported in Table 3. The trade openness variable remains negative and significant in highly liberal means

high openness religious belief groups of countries. This confirms our previous findings that high liberal religious belief does not necessarily facilitate the countries’ economic growth. Instead, results demonstrate that other institutional and macroeconomic variables like autocratic regimes and social and financial globalization substantially affect countries’ economic growth. Our results provide considerable evidence for the hypothesis that countries with highly liberal religious beliefs can promote growth, which goes beyond the existing findings on the association between economic growth and trade policy.

Further, results reveal that economic uncertainty across countries adversely affects the economic growth of various countries. This suggests that countries with a high volatility of uncertainty in democratic regimes and high economic uncertainty reversely affect economic growth. Nevertheless, external effects like expenditure on human capital, an essential element in the growth of knowledge and skills of the labour, argued that the population with human capital has a similar role in enhancing economic growth. Hence, we can say that HDI promotes growth through higher trade flows.

This study attempts to differentiate the heterogeneous role of trade openness in growth acceleration among countries under various categories of religious freedom. Further, by introducing a political set-up (democratic-autocratic governance) within our model alongside religious freedom, we conclude that countries endowed with high liberals in religious belief experience more significant growth in income per capita. Our results are robust in accounting for institutional, macroeconomic, and specific control variables and correcting possible endogeneity in estimation. Further, improved social openness, increased human development, and increased religious tolerance could accelerate economic growth. Empirical results reveal that the relationship between openness to trade and economic growth across developing countries is subject to the institutional environment.
