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...

This paper presents two arguments in favor of the sole use of an income tax for redistribution purposes. The first is that most findings on nonlinear commodity taxation such as Mirrlees's formulae for Pareto efficiency, Seade's results on zero tax rates at the endpoints of the scale, and 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...

What is the effect of ambiguity aversion on trade? Although in a Bewley's model ambiguity aversion always lead to less trade, in other models this is not always true. However, we show that if the endowments are unambiguous then more ambiguity aversion implies less trade, for a very general class...

Willig (1976) argues that the change in consumer's surplus is often a good approximation to the willingness to pay for a price change: if the income elasticity of demand is small, or the price change is small, then the percentage error from using consumer's surplus is small. If the price of a...

This paper argues that the Kyoto Protocol to the 1992 Framework Convention on Climate Change was doomed to face difficulties ab initio. It explains why this is the case by analyzing the Kyoto Protocol’s shortcomings and deficiencies. Moving the climate change agenda forward multilaterally...

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...

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...

The optimal income tax model under the threat of migration is extended to include both indirect taxes and public goods. This has enabled us to check that: 1) optimal income tax rates are higher than in the absence of indirect taxes and, at the top of the skills distribution, may be positive; 2)...
