We compare economic and environmental outcomes under mixed and private oligopolies, in order to examine the effects of privatization when firms invest in abatement and emissions are taxed. We show that the number of competing firms in the market is an important factor in the determination of...

We study firms' adoption of flexible versus dedicated technologies in the context of a mixed versus a private duopoly with product differentiation. The flexible technology allows a firm to become multiproduct or multimarket without bearing additional costs. We find that a configuration where...

We construct a simple model of education and growth in which young adults (children) spend a fraction of their time and old adults (parents) spend a fraction of their income on education. Both a strategic complementarity and an intergener- ational externality in the creation of human capital are...

We construct an overlapping generations model in which parents vote on the tax rate that determines publicly provided education and offspring choose their effort in learning activities. The technology governing the accumulation of human capital allows these decisions to be strategic complements....

The effort to reduce pollution entails economic benefits because improved environmental quality advances the health status of the population and reduces mortality. Yet, there are also economic costs accruing from this effort because activities towards environmental improvement require resources...

I construct an overlapping generations model in which (the endogenous) longevity is impeded by the stock of pollution and promoted by public health spending. I provide an alternative explanation for the so-called environmental Kuznets curve – an explanation which gives an active role to...
