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...

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 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...

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 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,...

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 provide an analytical overview of the distortionary effects of some common forms of taxes faced by the nonrenewable resources sector of the economy. In the category of taxes meant specifically to capture the resource rent, we look at a specific severance tax, an ad valorem severance tax, a...

This paper investigates the negotiation over bribe and tax payments during the tax collection process in poor countries. We build a simple model where tax officials and firms bargain over bribes to let firms evade part of their taxes. Using a unique dataset on Ugandan firms we test the...

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...
