We consider electoral competition between two political candidates. Each can target private benefits to some groups. A candidate has an incentive to offer high benefits in the initial period, to deter the other candidate from offering yet higher benefits to the same group in a later period. We...

We consider cities which can increase the income of landowners or of capital owners by improving the quality of public services. The improvement can come from innovation or from imitation. We find that when cities aim to benefit landowners, too many cities innovate; but too few cities innovate...

Central governments often subsidize capital spending by local governments, instead of subsidizing operating expenses or labor-intensive projects. This paper offers one explanation, focusing on the incentive effects for local officials--a local official can more easily shift the cost of...

I consider the strategies that an opposition party can use against an incumbent party which controls the government. The focus is on strategies when citizens vote retrospectively (so that the incumbent's chance of winning re-election increases with his performance), and when citizens compare the...

Many mechanisms (such as auctions) efficiently allocate a good to the firm which most highly values it. But sometimes the owner of the asset or good may wish to transfer it only if it is not too valuable to potential buyers. The allocation problem becomes especially difficult when the potential...

A seller can benefit from information about the valuation a potential buyer places on the good. Under some circumstances, improved information raises social welfare. But under other circumstances, the information has private value but no social value, so that agents may spend too much on...

Given that it is difficult to monitor, and even more so to enforce, International Environmental Agreements, it is surprising that they are signed and implemented. This paper offers a theoretical model, which addresses the phenomena. The focus is on informational and coordination problems--a...

We consider a policymaker who must choose between the status quo and proposals made by lobbyists. Each lobbyist aims to maximize the tariff accorded his industry, but realizes that if he proposes too high a tariff, the policymaker may choose the proposal offered by another lobbyist which...

This paper develops a theory of consumer boycotts. Some consumers care not only about the products they buy but also about whether the firm behaves ethically. Other consumers do not care about the behavior of the firm but yet may like to give the impression of being ethical consumers....

Residents both enjoy the policies adopted in their cities, and choose those policies. If some people can better evaluate policies than can others, then the most perceptive people will be the most willing to move to the city with better policies, thereby making that city more likely to adopt good...
