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 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,...

We develop a framework for optimal taxation when agents can earn their income both in traditional activities, where private and social products coincide, and in rent-seeking activities, where private returns exceed social returns either because they involve the capture of pre-existing rents or...

The fundamentals of an exchange economy, the preferences of individuals, can be identified from the competitive equilibrium correspondence, which associates equilibrium prices of commodities to allocations of endowments; the argument extends to production economies. The essential step is the...

The main thrust of the paper is the design and the numerical analysis of new cap- and-trade schemes for the control and the reduction of atmospheric pollution. The tools developed are intended to help policy makers and regulators understand the pros and the cons of the emissions markets. We...

In this article, we extend Brouwer's fixed point theorem – which states that every continuous mapping f :B→B (a closed ball of Rn ) must have a fixed point – by allowing discontinuities of f, and we apply this extension to equilibrium theory in Economics.

The starting point of this paper is given by country situations where trade liberalization is expected to be poverty and inequality alleviating in the long run while inducing a short run increase in poverty or in inequality. The question we ask is what are the distributive aspects of trade which...

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...
