This paper considers the information systems induced by auditing policies in a principal- agent model with moral hazard. We point out that two such information systems A and B are seldom comparable using the customary mean-preserving spread relation between their respective likelihood ratio...

In this paper we estimate density functions for positive multivariate data. We propose a semiparametric approach. The estimator combines gamma kernels or local linear kernels, also called boundary kernels, for the estimation of the marginal densities with semiparametric copulas to model the...

Risk management is now present in many economic sectors. This paper investigates the role of risk management in creating value for financial institutions by analyzing U.S. property-liability insurers. Property-liability insurers are financial intermediaries whose primary role in the economy is...

In this article, we highlight the factors which influence governments in their decision to implement environmental policies of varying degrees of severity. We substantiate our arguments with analytical evidence from public interest theory and the economic theory of regulation (“interest group...

Several papers have tested the empirical validity of the migration models proposed by Borjas (1987) and Borjas, Bronars, and Trejo (1992). However, to our knowledge, none has been able to disentangle the separate impact of observable and unobservable individual characteristics, and their...

This paper examines the impact of the devaluation of the CFA franc in 1994 and of trade and fiscal reforms on enterprise development in Chad and Gabon. These reforms provide a natural experiment to assess the impact of trade liberalisation in countries with a small and backward manufacturing...

We propose a model of climate change consistent with four principal stylized facts. First, the benefits and costs of climate change mitigation policies are not evenly distributed across generations. Second, capital accumulation is not determined jointly with emissions policy, but rather as a...

The paper investigates the conflict that arises between the government, its bureaucrats and businesses in the tax collection process. We examine the effect of fiscal policy and corruption control mechanisms on the prevalence of tax evasion and corruption behaviour, and their impact on firm...

The 13-year American episode of the prohibition of alcohol (1919-1933) is so notorious and has been so extensively studied that there would not seem to be much to add. However, very little of this work has been done in a comparative and international perspective. Yet, the prohibition movement...

Cost-benefit analysts involved in evaluating projects influencing the risk of death and injury have access to a wide group of studies that provide a large range of estimates of the value of a statistical life (VOSL). It is of course a difficult task to pick the right estimate. This paper...
