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...

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,...

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...

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 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...

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...

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...

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...

In a situation where agents can only observe a noisy signal of the shock to future economic fundamentals, SVAR models can still be successfully employed to estimate the shock and the associated impulse response functions. Identification is reached by means of dynamic rotations of the reduced...
