Empirical evidence suggests that most advertisements contain little direct information. Many do not mention prices. We analyse a monopoly firm’s choice of advertising content and the information disclosed to consumers. The firm advertises only product information, price information, or both;...

We extend the persuasion game to bring it squarely into the economics of advertising. We model advertising as exciting consumer interest into learning more about the product, and determine a firm's equilibrium choice of advertising content over quality information, price information, and...

We model comparative advertising as brands pushing up own brand perception and pulling down the brand image of targeted rivals. We watched all TV advertisements for OTC analgesics 2001-2005 to construct matrices of rival targeting and estimate the structural model. These attack matrices identify...

We propose a normative theory of the number of representatives based on a stylized model of a representative democracy. We derive a simple formula, a "square-root theory" which gives the number of representatives in parliament as proportional to the square root of total population. Simple...

This paper studies management when the principal has different degrees of commitment power. In a model in which both the principal and agents are symmetrically uncertain about the agents' innate abilities, implicit incentives arise when the principal is not able to commit herself to long-term...

In this paper we propose estimates of the marginal cost of public funds (MCF) in 38 African countries. We develop a simple general equilibrium mode inspired by the “1-2-3” model of Devarajan et al. (1994) that can handle taxes on the five major tax classes, takes account of the informal...

The paper analyses governments’ trade-off between fiscal benefits and consumer surplus in privatization reforms of noncompetitive industries in developing countries. Under privatization, the control rights are transferred to private interests so that public subsidies decline. This benefit for...

The paper studies the impact of market integration on investment incentives in non-competitive industries. It distinguishes between investment in transportation and production cost-reducing technologies. Each domestic firm is controlled by a national regulator in a common market made of two...

The paper studies the impact of government budget constraint in a pure adverse selection problem of monopoly regulation. The government maximizes total surplus but incurs some cost of public funds à la Laffont and Tirole (1993). An alternative to regulation is proposed in which firms are free...

We study a class of representation mechanisms, based on reports made by a random subset of agents, called representatives, in a collective choice problem with quasi-linear utilities. We do not assume the existence of a common prior probability describing the distribution of preference types. In...
