What factors determine whether it is optimal with one or more technologies in a decarbonized road transport sector, and what policies should governments choose? We investigate these questions theoretically and numerically through a static, partial equilibrium model for the road transport market....

This paper examines stability of international climate agreements for carbon abatement under an optimal transfer rule and renegotiations. The optimal transfer rule suggested to stabilise international environmental agreements (Weikard 2005, Carraro, Eyckmans and Finus 2006) is no longer optimal...

Cost-benefit analyses require comparing costs and benefits that occur at different points in time. Doing so, however, creates conflicts between short-term considerations a discounting scheme has to be consistent with observed behaviours and long-term ethical issues a discounting scheme must not...

In this paper we investigate the effects of tax competition in a simple endogenous growth model with elastic labor supply. Our analysis focuses on two issues. First, we show that all taxes, i.e. on capital, labor, and consumption, are harmful for growth. Second, we derive the optimal tax policy....

We develop a model of education where individuals face educational risk. Successfully entering the skilled labor sector depends on individual effort in education and public resources, but educational risk still causes (income) inequality. We show that an optimal public policy consists of...
