In the Name of God! Religiosity and the Transition to Modern Growth
écrit avec With Lars Harhoff Andersen
We document the impact of religiosity on the development of science and education during the past millennium. We measure historic religiosity - or the intensity of religious upbringing - by exploiting that given names reveal the preferences and identities of parents, including their religious identity. We confirm that individuals who share first name with a major religious figure engage in more religious behaviors, reflected in their choice of studies, loyalty towards the church, and authors' writing topics, as well as response to natural disasters. We do so using data for more than 40.000 university students throughout the Holy Roman Empire and 330.000 authors writing during the past millennium. We proceed to document that knowledge production was slower in areas across Europe with more intense religious upbringing. To establish causality, we compare individuals that are very similar (university students or authors), born in the same area, and exploit that religiosity is measured at the parental level, while outcomes are measured at the level of the child. Our results contribute to a growing literature on the societal impact of differences in religious intensity

Non-Random Exposure to Exogenous Shocks: Theory and Applications
écrit avec Peter Hull
We develop new tools for estimating the causal effects of treatments or instruments that combine multiple sources of variation according to a known formula. Examples include treatments capturing spillovers in social and transportation networks, simulated instruments for policy eligibility, and shift-share instruments. We show how exogenous shocks to some, but not all, determinants of such variables can be leveraged while avoiding omitted variables bias. Our solution involves specifying counterfactual shocks that may as well have been realized and adjusting for a summary measure of non-randomness in shock exposure: the average treatment (or instrument) across such counterfactuals. We further show how to use shock counterfactuals for valid finite-sample inference, and characterize the valid instruments that are asymptotically efficient. We apply this framework to address bias when estimating employment effects of market access growth from Chinese high-speed rail construction, and to boost power when estimating coverage effects of expanded Medicaid eligibility.

The Winner-Take-All dilemma
We consider collective decision making when the society consists of groups endowed with voting weights. Each group chooses an internal rule that specifies the allocation of its weight to the alternatives as a function of its members' preferences. Under fairly general conditions, we show that the winner-take-all rule is a dominant strategy, while the equilibrium is Pareto dominated, highlighting the dilemma structure between optimality for each group and for the whole society. We also develop a technique for asymptotic analysis and show Pareto dominance of the proportional rule. Our numerical computation for the US Electoral College verifies its sensibility.
