In this paper, we show that the participation by an environmental group in a permit market does not necessarily result in more investment in abatement or even less pollution. There is a U-shaped relationship between the emission per unit of output and the extra weight given by the environmental...

We examine the use of subsidies to research and development (R&D) in a mixed and a private duopoly market. We show that the socially optimal R&D subsidy is increasing in the degree of spillovers, but it is lower in the private duopoly. The optimal R&D subsidy leads to an increase in total R&D...

We examine the use of subsidies to R&D in a mixed and a private duopoly market. We show that the socially optimal R&D subsidy is increasing in the degree of spillovers but it is lower in the private duopoly. The optimal R&D subsidy leads to an increase in total R&D and production, however, it...

We model an industry that supplies intermediate goods in a growing economy. Agents can choose whether to provide labour or to become firm owners and compete in the industry. The idea that entry is determined through occupational choice has major implications for the economy’s intrinsic...

We model an oligopolistic industry that supplies intermediate goods in an overlapping generations economy. Agents can choose whether to provide labour or to become entrepreneurs and compete in the industry. The idea that entry is determined through occupational choice has major implications for...

We model a market with environmentally conscious consumers and a duopoly in which firms consider the adoption of a clean technology. We show that as pollution increases, consumers shift more resources to the environmental activities, thereby affecting negatively the demand faced by the duopoly....

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...

It is often assumed that the airlines' fares increase monotonically over time, peaking a few days before the departure. Using fares for about 650 thousand flights operated by both Low-Cost and Full Service Carriers, we show several instances in which the monotonic property does not hold. We also...
