Religion and Economic Development - A study on Religious variables influencing GDP growth over countries

Religion is a popular topic to be considered as one of the major factors that affect people’s lifestyles. However, religion is one of the social factors that most economists are very careful in stating a connection with economic variables. Among few researchers who are keen to find how religions influence the economic growth, Barro had several publications with individual religious activities or beliefs and Montalvo and Reynal-Querol on religious diversity. In this paper, I challenge their studies by using more recent data, and test whether their arguments hold still for different data over time. In the first part of the paper, I first write down a simple macroeconomics equation from Mankiw, Romer, and Weil (1992) that explains GDP growth with several classical variables. I test Montalvo and Reynal-Querol (2003)’s variables – religious fragmentation and religious polarization – and look at them in their continents. Also, I test whether monthly attendance, beliefs in hell/heaven influence GDP growth, which Barro and McCleary (2003) used. My results demonstrate that the results from Barro’s paper that show a significant correlation between economic growth and religious activities or beliefs may not hold constant for different time period. My results also demonstrate neither religious fragmentation nor religious polarization is statistically significant with updated dataset. From these results, I suggest that religious variables do not have a significant, constant influence on economic growth.
