We measure the consequences of asymmetric information and imperfect competition in the Italian lending market. We show that banks' optimal price response to an increase in adverse selection varies with competition. Exploiting matched data on loans and defaults, we estimate models of demand for credit, loan use, pricing, and firm default. We find evidence of adverse selection and evaluate its importance. While indeed prices rise in competitive markets and decline in concentrated ones, the former effect dominates, suggesting that while market power can mitigate the adverse effects of asymmetric information, mainstream concerns about its effects survive with imperfect competition. * We thank

We study the effects of asymmetric information and imperfect competition in the market for small business lines of credit. We estimate a structural model of credit demand, loan use, pricing, and firm default using matched firm-bank data from Italy. We find evidence of adverse selection in the form of a positive correlation between the unobserved determinants of demand for credit and default. Our counterfactual experiments show that while increases in adverse selection increase prices and defaults on average, reducing credit supply, banks’ market power can mitigate these negative effects.

Abstract:We study whether leaders influence the unethical conduct of followers. To avoid selection issues present in natural environments, we use a laboratory experiment in which we form groups and assign leadership roles at random. We study an environment in which groups compete, with dishonest behavior enhancing group earnings to the detriment of social welfare. We vary, by treatment, two instruments through which leaders can influence follower conduct-prominent statements to the group and the allocation of monetary incentives. In general, the presence of active group leaders gives rise to significantly more dishonest behavior. Moreover, appointing leaders who are likely to have acted dishonestly in a preliminary stage of the experiment yields groups with significantly more unethical conduct. The analysis of leaders' strategies reveals that leaders' statements have a stronger effect on follower behavior than the ability to distribute financial rewards, and that leaders' propensity to act dishonestly correlates with their use of statements or incentives as a means for encouraging dishonest follower conduct.

An increasing number of households installing solar panels and consuming the energy thus produced raises two challenges for regulators: network financing and vertical equity. We propose alternative tariff and subsidy designs for policymakers to incentivise solar panel adoptions and guarantee that network costs are recovered, while trading off efficiency, equity, and welfare motives. We estimate a structural model of energy demand and solar panel adoption, using a unique matched dataset on energy consumption, prices, income, wealth, solar panel installations, and building characteristics for 165,000 households in Switzerland from 2008-2014. Our counterfactuals recommend the optimal solar panel installation cost subsidies and two-part energy tariffs to achieve a solar energy target. We show that, relative to installation cost subsidies, relying on marginal prices to incentivise solar panel adoptions is more cost efficient and progressive across the income distribution, but generates a larger aggregate welfare loss.
