We construct a model in which a number of equally powerful ethnic groups compete for power by engaging in civil war. In non-redistributive equilibrium, ethnically homogeneous and ethnically diverse countries face a lower probability of civil war than countries with a moderate degree of ethnic...

We present a growth model where agents divide time between rent seeking in the form of resource competition; and working in a human capital sector, interpreted as trade or manufacturing. Rent seeking exerts negative externalities on the productivity of human capital, generating multiple steady...

This paper analyses simultaneous regulation of cost and quality when firms have private, correlated information about productivity and the regulator receives a signal about quality. It is shown that managerial effort and expenditures on quality are positively correlated in the optimal contract....

We analyse network competition in a market with international calls. National regulatory agencies (NRAs) have incentives to set regulated termination rates above marginal cost to extract rent from international call termination. International network ownership and deregulation are alternatives...

We analyse in a theoretical framework the link between real-time and day-ahead market performance in a hydro-based and imperfectly competitive wholesale electricity market. Theoretical predictions of the model are tested on data from the Nordic power exchange, Nord Pool Spot (NPS).We reject the...

An increasing reliance on solar and wind power has raised concern about system ability to consistently satisfy electricity demand. This paper examines countries' unilateral incentives to achieve supply security through capacity reserves and market integration in a multinational electricity...

Horizontal shifts in bid curves observed in wholesale electricity markets are consistent with Cournot competition. Quantity competition reduces the informational requirements associated with evaluating market performance because the markups of all producers then depend on the same inverse...

We consider an economy with two language groups, where only agents who share a language can produce together. Schooling enhances the productivity of students and may modify their language endowment. Under a unilingual system, the language of the politically dominant group is the only language of...

We study commercialization of personal data through personalized advertising by a content platform. Content consumption generates productive data about consumer preferences. The firm invests in artificial intelligence (AI) to improve analytical power and in quality to stimulate content...

In a 'smart' electricity distribution network, flexible distribution resources (FDRs) can be coordinated to improve efficiency. But coordination enables whoever controls such resources to exercise market power. The paper establishes the following efficiency rankings of market structures:...
