We consider processes in which norms of behavior are transmetted through social of geographic networks.Agents adopt behaviors based on a combination of their inherent payoff and their local popularity (the number of neighbors who have adopted them) subject to some random error. Extending work of...

Power and conflict play virtually no role in mainstream economics, the main reason being the pervasive influence of the competitive model and the difficulty in incorporating quantitavely in formal models. Following some preliminary remarks on power, we proceed to an historical explanation of the...

We examine a model in which two politicians compete for office and for wages. Their remunerations are either set by the public or are offered competitively by the candidates during campaigns. Our main finding shows that competitive wage offers by candidates lead to lower social welfare than...

We examine whether the central bank council of a monetary union should publish its voting records when members are appointed by national politicians. We show that the publication of voting records lowers overall welfare if the private benefits of holding office are sufficiently low. High private...

It is widely recognized that active media can play a role in enhancing political competition by informing voters. Collusion between government and media can, however, undermine this role. We extend the political accountability model to include the presence of media outlets and the possibility...

Economists who believe that government is essentially benevolent tend to regard inter-governmental competition as a source of negative externalities that lower welfare. In contrast the public choice perspective, particularly that motivated by the Leviathan model, sees such competition as...

Donald Wittman's "Why Democracies Produce Efficient Results," argues that the "markets work, democracy fails" outlook typical of many economists rests on bad economics. After summarizing Wittman's main arguments, I maintain that Wittman too hastily accepts the assumption of voter rationality....

Traditionally, economic theory has by and large been a theory of markets or, more precisely, about market prices. However, there are at least two reasons why economic science should extend beyond price theory. First, markets do not function properly unless suitable contracts can be formulated...

We study the effect of team decision-making on bubbles and crashes in experimental asset markets of the kind introduced by Smith, Suchanek and Williams (1988). We find that populating such markets with teams of size two instead of individuals significantly reduces the severity of mispricing. In...
