This paper considers the problem of pet overpopulation. It develops a tractable dynamic model whose positive predictions square well with key features of the current U.S. market for pets. The model is used to understand, from a welfare economic perspective, the sense in which there is...

This paper computes welfare-maximizing monetary and fiscal policy rules in a real business cycle model augmented with sticky prices, a demand for money, taxation, and stochastic government consumption. We consider simple feedback rules whereby the nominal interest rate is set as a function of...

This paper presents a characterization of a welfare index for the evaluation of primary goods (to be understood as those goods that all agents should enjoy equally). The welfare associated with a given distribution of n primary goods among m agents is measured as the sum of n real-valued...

This paper extends Che and Gale (1998) by allowing the incumbent politician to have a preference for the policy position of one of the lobbyists. The effect of a contribution cap is analyzed where two lobbyists contest for a political prize. The cap always helps the lobbyist whose policy...

We show that the effects of tariff changes on welfare and import volume can be fully characterised by their effects on the generalised mean and variance of the tariff distribution. Using these tools, we derive new results for welfare- and market-access-improving tariff changes, which imply two...

A theory is developed of labor migration that is prompted by a desire to avoid social humiliation. In a general equilibrium framework it is shown that as long as migration can reduce humiliation sufficiently, migration will occur even between two identical economies. Migration increases the...

Conventional banking practices do not easily accommodate the financial needs of poor persons. Group-lending, on the other hand, has found several advantages in the context of poor borrowers with no collateral to offer. An important advantage is that the bank’s losses due to unsuccessful...

Performance budgeting schemes in the public sector have to operate with imperfect performance measures. We argue that these imperfections lead to wasteful fund-seeking (window dressing and lobbying) by the administrative units that produce public services. We develop a game-theoretical model to...

The study evaluates the efficiency of government intervention using a vertical structured model including imperfectly competitive agricultural input markets, the bread grain market, and the imperfectly competitive food industry. To test for policy efficiency the actually observed bread grain...
