Wage inequality between education groups in the United States has increased substantially since the early 1980s. The relative quantity of college-educated workers has also increased dramatically in the postwar period. This paper presents a unified framework where the dynamics of both skill...

This note shows that the assumptions about the abatement technology modify the impact of the environmental taxation (both the size and the “direction”) on the long-run growth driven by human capital accumulation à la Lucas (1988), when the source of pollution is private consumption and...

This paper investigates the impact of alternative environmental policy instruments on technological innovations aiming to improve energy-efficiency in buildings. The empirical analysis focuses on three main types of policy instruments, namely regulatory energy standards in buildings codes,...

This paper studies countries' incentives to develop advanced pollution abatement technology when technology may spillover across countries and pollution abatement is a global public good. We are motivated in part by the problem of global warming: a solution to this involves providing a global...

This paper analyses whether and how a climate policy designed to stabilize greenhouse gases in the atmosphere is likely to change the direction and pace of technical progress. The analysis is performed using an upgraded version of WITCH, a dynamic integrated regional model of the world economy....

WITCH is an energy-economy-climate model developed by the climate change group at FEEM. The model has been extensively used in the past 3 years for the economic analysis of climate change policies. WITCH is a hybrid top-down economic model with a representation of the energy sector of medium...
