This paper develops a framework for testing discrete complementarities in innovation policy using European data on obstacles to innovation. We propose a discrete test of supermodularity in innovation policy leading to a number of inequality constraints. We apply our test to two types of...

We provide a continuum of subsidy rules based on a performance indicator that induce a monopoly to choose the socially optimal production level. These subsidy rules result in a reduction of the amount of subsidy paid to the monopolist compared to the standard case where a constant subsidy rate...

This paper makes some steps toward a formal political economy of environmental policy. Economists' quasi-unanimous preferences for sophisticated incentive regulation is reconsidered. First, we recast the question of instrument choice in the general mechanism literature and provide an incomplete...

We analyze duopolistic competition between horizontally differentiated firms selling durable goods or services subject to congestion. At each point of time, new customers buy one unit of the commodity from one of the firms, by comparing present prices and future congestion rates. We study the...

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...

In the United States and most industrialized countries, regulatory policies and decision-making pertaining to food safety, occupational health and environmental protection are science-based. The actual pace and complexity of technological innovation, however, make it increasingly necessary to...

We address in this paper the problem of comparing and choosing among different policy instruments to implement the incentive objective of an efficient deterrence of environmental degradation and the remedy objective of an efficient clean-up of damages and a proper compensation of victims. Two...

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...
