What are the welfare effects of the information contained in macroeconomic statistics, central-bank communications, or news in the media? We address this question in a business-cycle framework that nests the neoclassical core of modern DSGE models. Earlier lessons that were based on "beauty...

Forecasting electricity demand for future years is an essential step in resource planning. A common approach is for the system operator to predict future demand from the estimates of individual distribution companies. However, the predictions thus obtained may be of poor quality, since the...

This paper provides a rational choice-based analysis of the causes and consequences of surprise events. The paper argues that ignorance may be rational, but nonetheless produce systematic mistakes, inconsistent behavior, and both pleasant and unpleasant surprises. If ignorance and unpleasant...

Ranking have become increasingly popular on markets for study programs, restaurants, wines, cars, etc. This paper analyses the welfare implication of such rankings. Consumers have to make a choice between two goods of unknown quality with exogenous presence or absence of an informative ranking....

Myopic consumers underestimate the likelihood with which they will require follow-on services for products they purchase. Firms have an incentive to exploit this behavioral bias by skewing their price structure toward high add-on charges. Inadvertently, this skewed price structure provides...

the well-known Atkinson and Stiglitz (1976, section 5) theorem on the superiority of nonlinear direct taxation over nonlinear indirect taxation is proved to hold under the second order approach, even on intervals where the monotonicity constraint is binding. this confirms for the nonlinear case...

We consider a monopolistic firm producing a good while polluting. This firm can adopt a cleaner technology within a finite time by incurring an investment cost decreasing exponentially with the adoption date. The firm is induced to adopt the cleaner technology at the socially optimal date by an...

We survey theoretical developments in the literature on the limits of arbitrage. This literature investigates how costs faced by arbitrageurs can prevent them from eliminating mispricings and providing liquidity to other investors. Research in this area is currently evolving into a broader...

This paper analyses the problem of natural resource scarcity and its implications for economic development and international cooperation. We examine the meaning and measurement of resource “scarcity” and its implications for economic growth and development. The paper describes the conditions...

This paper incorporates mobility between the legal and black economies into a model of tax evasion with endogenous labor supply in which underreporting is possible in one sector but impossible in the other. We have found that the results of the effects along the extensive margin (number of...
