This paper explores semi-monotonicity constraints in the distribution of potential outcomes, first, conditional on an instrument, and second, in terms of the response function. The imposed assumptions are strictly weaker than traditional instrumental variables assumptions and can be gainfully...

Advertisements provide consumers with knowledge about private products, whereas political information is required to provide voters with knowledge of public issues. Modern information technologies and globalisation are increasing the exposure of individuals to information. Goods advertising is...

This paper investigates the design of incentives in a dynamic adverse selection framework when agents' production technologies display learning effects and agents' rate of learning is private knowledge. In a simple two-period model with full commitment available to the principal, we show that...

We examine how globalization affects firms incentives to train workers. In our model, firms invest in productivity-enhancing worker training before Cournot competition takes place. When two separated product markets become integrated and are thus replaced with a market with greater demand and...

We analyze the determinants of environmental policy when two firms engage in two types of lobbying against a restriction on allowed pollution: General lobbying increases the total amount of allowed pollution, which is beneficial for both firms. Private lobbying increases the individual pollution...

This paper analyzes the identifying power of weak convexity assumptions in treatment effect models with endogenous selection. The counterfactual distributions are constrained either in terms of the response function, or conditional on the realized treatment, and sharp bounds on the potential...

Under certain conditions the optimal insurance policy will offer full coverage above a deductible, as Arrow and others have shown long time ago. Interestingly, the same design of insurance policies applies in case of a single loss and ex-ante moral hazard. However, many insurance policies...

We consider a setting in which two potential merger partners each possess private information pertaining both to the profitability of the merged entity and to stand-alone profits, and we investigate the extent to which this private information makes ex-post regret an unavoidable phenomenon in...

This paper examines the role of simplified heuristics in the formation of preferences for public goods. Political scientists have suggested that voters use simplified heuristics based on the positions of familiar parties to infer how a proposed policy will affect them and to cast a vote in line...
