We define a model of peer effects where the intra-group externality is rooted on the network of bilateral influences in the population, rather than consisting on an average effect. Using game theory, we then map the geometric intricacies of this network structure to the distribution of...

We propose a new theory for downsizing, based on strategic reasons, rather than technological ones. A crisis may lead to a decrease in the willingness to cooperate in an organization, and therefore to a bad equilibrium. A consensual downsizing episode may signal credibly that survivors are...

We study the earning structure and the equilibrium assignment of workers to firms in a model in which workers have social preferences and skills are perfectly substitutable in production. We allow firms to offer long terms contracts and for frictions in the labour market in the form of mobility...

It is often alleged that high auction prices inhibit build-out. We investigate this claim under the extreme case of budget-constrained bidders. Low prices maximize overall the gains from trade. If there are n licenses, the price where the budget constraint just binds maximizes consumer surplus...

This paper evaluates new evidence on price setting practices and inflation persistence in the euro area with respect to its implications for macro modelling. It argues that several of the most commonly used assumptions in micro-founded macro models are seriously challenged by the new findings.

In monetary unions, monetary policy is typically made by delegates of the member countries. This procedure raises the possibility of strategic delegation- that countries may choose the types of delegates to influence outcomes in their favor. We show that without commitment in monetary policy,...

A generalized rise in unemployment rates for both college and high-school graduates, a widening education wage premium, and a sharp increase in college education participation are characteristic features of the transformations observed in the U.S. labor market between 1970 and 1990. This paper...

Finance is important for development, yet the onset of modern economic growth in Britain lagged the British financial revolution by over a century. We present evidence from a new West-End London private bank to explain this delay. Hoare's Bank loaned primarily to a highly select and well-born...

This paper presents a stylized model of economic growth with bubbles. This model views asset price bubbles as a market-generated device to moderate the effects of frictions in financial markets, improving the allocation of investments and raising the capital stock and welfare. The model...
