We study a general equilibrium model where agents' preferences, productivity and labour endowments depend on their health status, and occupational choices affect individual health distributions. Efficiency typically requires agents of the same type to obtain different expected utilities if...

I study how savers allocate funds between boundedly rational firms which follow simple pricing rules. Firms need cash to pay their inputs in advance, and savers-shareholders allocate cash between them so as to maximize their rate of return. When the rate of return on each firm is observed, there...

We consider a pure exchange economy, where for each good several trading institutions are available, only one of which is market-clearing. The other feasible trading institutions lead to rationing. To learn on which trading institutions to coordinate, traders follow behavioural rules of thumb...

We propose a formal concept of the power of voice in the context of a simple model where individuals form groups and trade in competitive markets. Individuals use outside options in two different ways. Actual outside options reflect the possibility to exit or to join other existing groups....

We use a North-South model with property right differences and resource dynamics to study the effects of trade on resource use and welfare. Autarky is likely to Pareto-dominate free trade in the long run when the environment is quite fragile, and the result is reversed when the environment is...

We propose a rational theory of momentum and reversal based on delegated portfolio management. A competitive investor can invest through an index fund or an active fund run by a manager with unknown ability. Following a negative cashflow shock to assets held by the active fund, the investor...

We study a dynamic general equilibrium model in which firms choose their investment level and their capital structure, trading off the tax advantages of debt against the risk of costly default. The costs of bankruptcy are endogenously determined, as bankrupt firms are forced to liquidate their...

The aim of the paper is to present a review of the fiscal imbalances and debt crisis in Greece and identify the possible links with the recent developments in the Greek property market. We follow a non-technical approach to discuss a number of factors that have contributed to the fiscal crisis...

We study competitive market outcomes in economies where agents have other-regarding preferences. We identify a separability condition on monotone preferences that is necessary and sufficient for one's own demand to be independent of the allocations and characteristics of other agents in the...

We build an occupational-choice general-equilibrium model of an economy with the non-profit sector financed through private warm-glow donations. Lack of monitoring on the use of funds implies that an increase of funds of the non-profit sector (because of a higher income in the for-profit sector,...
