We estimate how random weather fluctuations affected infant mortality across 28 African countries in the past, combining high-resolution data from retrospective fertility surveys (DHS) and climate-model reanalysis (ERA-40). We find that infants were much more likely to die when exposed in utero...

We argue exogenous random treatment is insufficient for valid inference regarding the sign and magnitude of causal effects in dynamic environments. In such settings, treatment responses must be understood as contingent upon the typically unmodeled policy generating process. With binary...

We use data from a television game show, involving elementary lotteries and substantial prize money, as a natural experiment to measure risk attitudes. We find robust evidence of substantial risk aversion. As an extension, we esimate the various models using transformations of the ‘true’...

If in general, financial deepening aids economic growth, then financial repression should be harmful. We use a natural experiment – the change in the English usury laws in 1714 – to analyse the effects of interest rate restrictions. Based on a sample of individual loan transactions, we...

Measures of urban productivity are typically positively associated with city population. But is this relationship causal? We discuss the main sources of bias in the proper identification of agglomeration effects. We also assess a variety of solutions that have been proposed in the literature to...

We study ex post information rents in sequential screening models where the agent receives private ex ante and ex post information. The principal has to pay ex post information rents for preventing the agent to coordinate lies about his ex ante and ex post information. When the agent's ex ante...

Empirical evidence suggests that most advertisements contain little direct information. Many do not mention prices. We analyse a monopoly firm’s choice of advertising content and the information disclosed to consumers. The firm advertises only product information, price information, or both;...

This paper revisits recent empirical research on buyer credulity in arts auctions and auctions for assets in general. We show that elementary results in auction theory can fully account for some stylized facts on asset returns that have been held to suggest that sellers of assets can exploit...

This paper analyses the impact of public disclosure of banks’ risk exposure on banks’ risk taking incentives and its implications in terms of soundness of the banking system. We find that, when banks have a complete control over the volatility of their loan portfolio, public disclosure...

This paper studies the impact of competition on the determination of interest rates, and on banks’ risk taking behaviour, under different assumptions about deposit insurance and the dissemination of financial information. We find that lower entry costs foster competition in deposit rates and...
