Sascha O. Becker of Monash University and University of Warwick reviews “The Divine Economy: How Religions Compete for Wealth, Power, and People” by Paul Seabright. The Econlit abstract of this book begins: “Presents a platform model of religious movements, discussing how the competition for members and resources between such movements shapes what is possible for them and their political backers.”

How large is entrepreneurs’ personal importance to startups? We use the death of nearly 1,500 entrepreneurs as a source of exogenous variation, and find large and sustained negative effects on growth and profitability. For small startups, the effects go mainly via firm survival, while for larger startups the effects are mainly on firm growth. For larger startups, the mean effect on sales is about 60%. The effects appear to be driven by entrepreneur specialness rather than leadership transition; the effects of death of entrepreneur managers are economically and statistically stronger than the death of managers that are not entrepreneurs.

Max Weber attributed the higher economic prosperity of Protestant regions to a Protestant work ethic. We provide an alternative theory: Protestant economies prospered because instruction in reading the Bible generated the human capital crucial to economic prosperity. We test the theory using county-level data from late-nineteenth-century Prussia, exploiting the initial concentric dispersion of the Reformation to use distance to Wittenberg as an instrument for Protestantism. We find that Protestantism indeed led to higher economic prosperity, but also to better education. Our results are consistent with Protestants' higher literacy accounting for most of the gap in economic prosperity.

We explore the link between portfolio home bias and consumption risk sharing among Italian regions using household-level information on consumption, income and portfolio holdings. Since equity funds are typically diversified at the national or international level, we use data on equity fund ownership to proxy for regional home bias. Cross-regional patterns of equity fund ownership are qualitatively consistent with simple portfolio theory: regions with more asymmetric business cycles are more diversified because they have higher fund participation rates (the extensive margin of diversification) and higher average holdings of equity funds (diversification’s intensive margin). Also, fund holdings increase with the exposure of non-tradable income components (such as labor or entrepreneurial income) to regional shocks. Finally, interregional consumption risk sharing increases with fund holdings and this effect seems strongest when participation is widespread. Increased equity market participation could substantially improve interregional risk sharing.

In an economic theory of suicide, we model social cohesion of the religious community and religious beliefs about afterlife as two mechanisms by which Protestantism increases suicide propensity. We build a unique microregional data set of 452 Prussian counties for 1816 to 1821 and 1869 to 1871, when religiousness was still pervasive. Exploiting the concentric dispersion of Protestantism around Wittenberg, our instrumental variable model finds that Protestantism had a substantial positive effect on suicide. Results are corroborated in first-difference models. Tests relating to the two mechanisms based on historical church attendance data and modern suicide data suggest that the sociological channel plays the more important role.

We study the role of economic incentives in shaping the coexistence of Jews, Catholics, and Protestants, using novel data from Germany for 1,000+ cities. The Catholic usury ban and higher literacy rates gave Jews a specific advantage in the moneylending sector. Following the Protestant Reformation (1517), the Jews lost these advantages in regions that became Protestant. We show (i) a change in the geography of anti-Semitism with persecutions of Jews and anti-Jewish publications becoming more common in Protestant areas relative to Catholic areas; (ii) a more pronounced change in cities where Jews had already established themselves as moneylenders. These findings are consistent with the interpretation that, following the Protestant Reformation, Jews living in Protestant regions were exposed to competition with the Christian majority, especially in moneylending, leading to an increase in anti-Semitism.

The interplay between religion and the economy has long occupied social scientists. We construct a unique panel of income and Protestant church attendance using 175 Prussian counties, presented in six waves from 1886 to 1911. The data reveal a marked decline in church attendance coinciding with increasing income. The cross-section also shows a negative association between income and church attendance. The associations disappear in panel analyses, including first-differenced models of the 1886 to 1911 change, panel models with county and time fixed effects, and panel Granger-causality tests. The results cast doubt on causal interpretations of the religion-economy nexus in Prussian secularization.

Employment at multinational enterprises (MNEs) responds to wages at the extensive margin, when an MNE enters a foreign location, and at the intensive margin, when an MNE operates existing affiliates.

We use the elements of a macroeconomic production function—physical capital, human capital, labor, and technology—together with standard growth models to frame the role of religion in economic growth. Unifying a growing literature, we argue that religion can enhance or impinge upon economic growth through all four elements because it shapes individual preferences, societal norms, and institutions. Religion affects physical capital accumulation by influencing thrift and financial development. It affects human capital through both religious and secular education. It affects population and labor by influencing work effort, fertility, and the demographic transition. And it affects total factor productivity by constraining or unleashing technological change and through rituals, legal institutions, political economy, and conflict. Synthesizing a disjoint literature in this way opens many interesting directions for future research. (JEL E22, I25, J10, N30, O33, O43, Z12)

We study the long-run effects of forced migration on investment in education. After World War II, millions of Poles were forcibly uprooted from the Kresy territories of eastern Poland and resettled (primarily) in the newly acquired Western Territories, from which the Germans were expelled. We combine historical censuses with newly collected survey data to show that, while there were no pre-WWII differences in educational attainment, Poles with a family history of forced migration are significantly more educated today than other Poles. These results are driven by a shift in preferences away from material possessions toward investment in human capital. (JEL I25, I26, J24, N34, R23)
