We study electoral competition among politicians who are heterogeneous both in competence and in how much they care about (what they perceive as) the public interest relative to the private rents from being in office. We show that politicians may have stronger incentives to behave...

We present a dynamic model of the interaction between interest groups and policymakers, featuring endogenous interest group formation. We show that complicated dynamic patterns in economic policies may arise once interest group formation is taken into account. <BR><BR>

We develop a simple two period model to study the importance of motivational differences among politicians in describing the role of elections and explaining policy choices. In our model, politicians differ in their motives of running public office. Good politicians care about policies while bad...

We provide an explanation why centralisation of political decision making

Democracies delegate substantial decision power to politicians. Using a model in which an incumbent can design, examine and implement public policies, we show that examination takes place in spite of, rather than thanks to, elections. Elections are needed as a carrot and a stick to motivate...

This paper examines the incentives for a party leader in office and for a parties' rank-and-file to replace a sitting member of parliament. As to the leader's decision, we show that the leader prefers to replace a critical member of parliament who votes against the leader's policy. A competent...

A firm may induce voters or elected politicians to support a policy it favors by suggesting that it is more likely to invest in a district whose voters or representatives support the policy. In equilibrium, no one vote may be decisive, and the policy may gain strong support though the majority...

We consider an oligopolistic market where firms compete in price and quality and where consumers are heterogeneous in knowledge: some consumers know both the prices and quality of the products offered, some know only the prices and some know neither. We show that two types of signalling...

This paper discusses the design, implementation and use of standards from the perspective of transaction costs economics. A proper design and implementation of standards may lead to a considerable reduction of transaction costs, which enhances trade and, consequently, economic welfare. A major...

This paper investigates the response of full service carriers (FSCs) to the entry of low-cost carriers (LCCs). We develop a model of airline competition, which accommodates various market structures, some of which include low-cost players. Using data on published airfares of Lufthansa, British...
