This paper performs a welfare analysis of economies with private information when public information is endogenously generated and agents can condition on noisy public statistics in the rational expectations tradition. We find that equilibrium is not (restricted) efficient even when feasible...

We develop a simple theory which formally describes how charities can resolve the information asymmetry problems faced by small donors by working with large donors to generate quality signals. To test the model, we conducted two large-scale natural field experiments. In the first experiment, a...

An agent can make an observable but non-contractible investment. A principal then offers to collaborate with the agent to provide a public good. Private information of the agent about his valuation may either decrease or increase his investment incentives, depending on whether he learns his type...

We re-address the tradeoff between centralized and decentralized decision making of local policies when policymakers are subject to capture by special interest groups. In particular, we consider the case where lobbies have private information about their ability to exert influence. We find a new...

An autocoherent model is a model which is validated by the data if people use it to form their expectations. A structural model may be incorrect but autocoherent, thus supporting a self-confirming equilibrium. This paper explores some mathematical properties of autocoherent models. The first...

The banking crisis has caused a resurgence of interest in behavioural models of expectations in macroeconomics. Here we evaluate behavioural and rational expectations econometrically in a New Keynesian framework, using US post-war data and the method of indirect inference. We find that after...

From a theory viewpoint, the use of auctions with zero public reserve prices also called absolute auctions, or the use of auctions with secret reserve prices is somehow puzzling despite being common. By allowing that buyers differ in their processing of past data regarding how the participation...
