An economy with clean and dirty intermediate inputs may fall into a trap characterized by low environmental quality and low life expectancy, while the others converge to opposite steady states. We propose new strategies towards sustainable growth. They include: (i) taxes (subsidies) imposed on...

In this paper, we study a two-country dynamic setup with environmental externalities and potential model misspecification in relation to this public good. Under model uncertainty, robust policies help to correct the inefficiencies associated with free riding on public good provision, implying...

This paper explores how a principal with time-inconsistent preferences invests optimally in technology or capital. If the current principal prefers her future self to save more, she can increase current investments complementary to future savings and decrease investments in the strategic...

This paper develops a general-equilibrium model of skill-biased technological change that approximates the observed shifts in the shares of wage and non-wage income going to the top decile of U.S. households since 1980. Under realistic assumptions, we find that all agents can benefit from the...

Conventional wisdom argues that environmental policy is less costly if environmental policy induces the development of cleaner technologies. In contrast to this argument, we show that the cost of environmental policy (a reduction in emissions) may be larger with induced technical change than...

When providing public goods through voluntary contributions, a donor may introduce unilateral matching in order to reduce underprovision of the public good and thus inefficiency. By itself, however, matching benefits the donor but harms the recipient. We apply Cornes and Hartley’s aggregative...

In our analytical general equilibrium model where two polluting inputs can be substitutes or complements in production, we study the effects of a tax on one pollutant in two cases: one where both pollutants face taxes and the second where the other pollutant is subject to a permit policy. In...

This paper analyzes the implications of potential offenders caring about their relative status. We establish that subjects' status concerns can result in multiple-equilibrium crime rates and may modify the standard comparative-statics results regarding how the crime rate changes in response to a...

We consider environmental regulation in a context where firms invest in abatement technology under conditions of uncertainty about subsequent abatement cost, but can subsequently adjust output in the light of true marginal abatement cost. Where an emission tax is the only available instrument,...
