The conference of Kyoto 1997 instutionalized a new and important economic instrument for environmental protection, the Joint Implementation Progran (JI). The concept of Joint Implementation involves a bilateral or multilateral deal in which countries facing high pollution abatment costs invest...

We use a version of the neoclassical growth model economy to evaluate two revenue neutral flat-tax reforms. In the less progressive flat-tax reform the households face a 22 percent integrated flat tax and a labor income tax exemption of \$16,000 per household. In the more progressive flat-tax...

We use a Computable General Equilibrium model to simulate the effects of an Environmental Tax Reform in a regional economy (Andalusia, Spain). The reform involves imposing a tax on CO2 or SO2 emissions and reducing either the Income Tax or the payroll tax of employers to Social Security, and...

This paper introduces the quest for status into the Ramsey model with endogenous labor supply. We focus our attention on relative wealth preferences. In contrast to relative consumption preferences, they allow for the possibility that agents work too little in the long run, while under both...

We investigate possible determinants of the increase of household debt and smaller consumption fluctuations since the 1980s in the US. We use a heterogeneous-agent model, in which labor income is risky and markets are incomplete. Consumers use durables not only as collateral for their debt but...

Recently David Laibson (1998) and others have argued in favor of using hyperbolic discount functions. The purpose of this paper is to investigate whether conventional wisdom, based on the standard model with exponential discounting, also holds in the case where consumers have hyperbolic discount...

In this paper we show the extent that home ownership varies over the life-cycle and differs by cohort and by education. We explain these differences in a calibrated model of life-cycle behaviour where households choose labour supply and consumption and also home-ownership status. Home-ownership...
