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....

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...

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...

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,...

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...

This paper views authority as the right to undertake decisions that impose externalities on other members of the organization. When only decision rights can be contractually assigned to one of the organization's stakeholders, the optimal assignment minimizes the resulting inefficiencies by...

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...

This paper provides a brief, non-technical survey of the major theories about why people remain unemployed. The aim is to provide a macroeconomic perspective on the microeconomic problem of why people don't find work. The first section deals with market-clearing theories: the natural rate...

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...
