We discuss the quota system by which Iceland’s fisheries have been managed since 1984, and explore its implications for economic efficiency as well as fairness. We argue that the shortcomings of the Icelandic quota system are inherent in any type of quota system applied to high-seas fishing....

This paper examines how the distribution of prices and consumer welfare change with the number of competitors in a model where consumers di¤er in the amount of price information they have. We only assume that an increase in the number of competitors results in an increase in the probability...

Protectionism enjoys surprising popular support, in spite of deadweight losses. At the same time, trade barriers appear to decline with public information about protection. This paper develops an electoral model with heterogeneously informed voters which explains both facts and predicts the...

Uncertainty about the riskiness of a new financial environment was an important factor behind the U.S. credit crisis. We show that a boom-bust cycle in debt, asset prices and consumption characterizes the equilibrium dynamics of a model with a collateral constraint in which agents learn "by...

This paper analyses the impact of inequality on growth when technical progress is driven by innovations. It is assumed that consumers have hierarchic preferences. As a result inequality affects demand and therefore the incentive to innovate. Whether more inequality is harmful or beneficial for...

It is often argued that a mandatory minimum wage is binding only if the wage density displays a spike at it. In this Paper we analyse a model with search frictions and heterogeneous production technologies, in which imposition of a minimum wage affects wages even though, after imposition, the...

In markets with imperfect information and heterogeneity, the information technology affects the rate at which agents meet, which in turn affects the distribution of production technologies across firms. We show that in models for such markets there are typically multiple equilibria because...

Imperfect information has played a prominent role in modern business cycle theory. This paper assesses its importance by estimating the New Keynesian (NK) model under alternative informational assumptions. One version focuses on confusion between temporary and persistent disturbances. Another,...

We analyse competition among banks when banks can use creditworthiness tests that generate (imperfect) information about borrowers. When banks can strategically adjust the test characteristics by investing resources in the screening technology, we show that credit markets are not easily...

Floating exchange rates display substantial short-run volatility causing a nontrivial information problem in disentangling temporary from permanent changes. Although agents observe current market signals they are imperfectly informed about the future, but they accumulate information and learn...
