Using a formal political economy model with incomplete information regarding the accident preventing activities chosen by the firm (moral hazard) under limited liability, we illustrate different conditions under which an environmental protection system based on extending liability to private...

We characterize the distortions in environmental liability sharing between firms and banks that the imperfect implementation of government policies implies. These distortions stem from three factors: the presence of moral hazard, the use of objective functions by firms and banks that differs...

Using a structural model of the interactions between governments, firms and insurance companies, we characterise the distortions in environmental liability sharing between firms and insurance companies that the imperfect implementation of government policies implies. These distortions stem from...

We focus in this paper on the effects of court errors on the optimal sharing of liability between firms and financiers, as an environmental policy instrument. Using a structural model of the interactions between firms, financial institutions, governments and courts we show, through numerical...

I provide a complete characterization of Nash implementable allocations of spending in prevention by judgement-proof injurers. This characterization is used to identify the optimal rule that allows for the maximum total spending in prevention. The optimal rule amounts to apply the negligence...

In this paper, we study specialty physician decisions using several unique data sets which include information on almost all Canadian physicians who practiced in Canada between 1989 and 1998. Unlike previous studies, we use a truly exogenous measure of potential income across general and...

In this paper, we address the dynamics associated with living-arrangement decisions of sick, elderly individuals. Using data from the Panel Study of Income Dynamics and its Parental Health Supplement, we construct the complete living-arrangement histories of elderly individuals in need of care....

There is a strong negative relationship between economic development and HIV/AIDS prevalence throughout the world. However in Sub-Saharan Africa where the epidemic is worst, this relationship does not hold. Some of the wealthier countries in this region have some of the highest rates of HIV/AIDS...

We analyse how physicians respond to contractual changes and incentives within a multitasking environment. In 1999 the Quebec government (Canada) introduced an optional mixed compensation (MC) system, combining a fixed per diem with a partial (relative to the traditional fee-for-service system)...

We develop and estimate a generalized labour supply model that incorporates work effort into the standard consumption-leisure trade-off. We allow workers a choice between two contracts: a piece rate contract, wherein he is paid per unit of service provided, and a mixed contract, wherein he...
