This paper analyses the decision to invest to reduce the emissions of a stock pollutant under environmental uncertainty. It shows that this decision depends on the type and level of uncertainty. When uncertainty is small, there is no simple irreversibility effect because of the tension between...

We study the welfare effects of government-backed FDIs in Africa’s farmlands. We build an occupational choice model featuring four mechanisms driving these effects. First, local farming is subject to social arrangements prescribing that farmers share their crop surplus with kin. Second,...

The key element in the tension between those who believe climate change is an issue and those who do not is essentially the question of whether we are merely in a long period of shock-induced above average temperatures or if we have led to this increase in temperatures by anthropogenic carbon...

Using an extension of Lucas' model of endogenous growth with education externality, we show that an environmental tax may increase growth. This is because the tax makes physical capital accumulation less attractive, thereby correcting for the underinvestment by agents in human capital.

The Porter hypothesis predicts that environmental regulations (ER) should have a positive impact on the productivity of the regulated firms. In this paper, we review the theoretical and empirical arguments surrounding this hypothesis. We show that there are relatively few formal theoretical...

Selon l'hypothèse de Porter, des réglementations environnementales (RE) strictes doivent avoir un impact positif sur la productivité des firmes touchées. Dans ce papier, nous revoyons les arguments théoriques et empiriques entourant cette hypothèse. Nous montrons qu'il existe peu de...

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...

We compute the optimal non-linear tax policy for a dynastic economy with uninsurable risk, where generations are linked by dynastic wealth accumulation and correlated incomes. Unlike earlier studies, we find that the optimal long-run tax policy is moderately regressive. Regressive taxes lead to...

This article draws up a portrait of effective marginal tax rates (EMTRs) on labour income in Quebec. It aims at allowing a better understanding of the impact of tax policy on the behavior of economic agents. Using an accounting microsimulation model that reproduces the system of taxes and...
