We shed light on the function, properties and optimal size of austerity using the standard sovereign model augmented to include incomplete information about credit risk. Austerity is defined as the shortfall of consumption from the level desired by a country and supported by its repayment...

Two well-known, but seemingly contradictory, features of exchange rates are that they are close to a random walk while at the same time exchange rate changes are predictable by interest rate differentials. In this paper we investigate whether these two features of the data may in fact be...

The harshest criticism of econometrically based policy evaluation is undoubtedly the sensitivity of its conclusions to assumptions concerning the information available to policy-makers or to misspecification of the econometric models used in the evaluation. Economists appear to have accepted...

This Paper studies a principal-agent model of the relationship between officeholder and an electorate, where everyone is initially uninformed about the officeholder’s ability. If office-holder effort and ability interact in the determination of performance in office, then an office-holder has...

A firm must decide whether to launch a new product. A launch implies considerable fixed costs, so the firm would like to assess downstream demand before it decides. We study under which conditions a potential buyer would be willing to reveal his willingness to pay under different pricing...

A student's future log-wage is given by the sum of a skill premium and a random personal ‘ability’ term. Students observe only a private, noisy signal of their ability, and universities can condition admission decisions on the results of noisy tests. We assume first that universities are...

Firms' incentives to form research joint ventures (RJVs) are analysed in an incomplete information framework when technological know-how is private information. Firms first decide on cooperation and information revelation and then compete for a patent. Provided that spillovers exist in the case...

Economic decisions such as occupational and entrepreneurial choices may violate true comparative advantage when economic agents are uncertain about which activity best matches their talents. If relative performance varies over the business cycle (for instance, if downturns affect...

We study a class of representation mechanisms, based on reports made by a random subset of agents, called representatives, in a collective choice problem with quasi-linear utilities. We do not assume the existence of a common prior probability describing the distribution of preference types. In...

This paper shows that delegation of monetary policy to a weight-conservative central banker is optimal, although the government can also use an inflation contract, an employment target, an inflation target, or any combination of these, to control the central banker. The key feature of our model...
