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....

In a model where seignorage provides the financing instrument for the government’s budget, public spending volatility has an adverse effect on long-run growth. This negative relationship arises because the incidence of volatility in this type of public policy is responsible for higher average...

In a monetary growth model, I show that average inflation inhibits growth while inflation volatility enhances it. The effect of nominal volatility on human capital accumulation depends on the response of money demand and the corresponding extent of transactions costs rather than from a direct,...

We present evidence on the effects of aid transfers and their degree of volatility on economic growth and show that these effects can be categorised in relation to the allocation of foreign aid between productive and non-productive purposes. Using a stochastic endogenous growth model, we provide...
