We study the competition to operate an infrastructure service by developing a model where firms must report a two-dimensional sealed bid: the price to consumers and the concession fee paid to the government. Two bidding rules are considered in this paper. One rule consists of awarding the...

In this article we study the long-run average rate of forest conversion in Brazil. Deforestation results from the following trade-off: on the one hand, the uncertain value of benefits associated with forest conservation (biodiversity, carbon sequestration and other ecosystem services), on the...

In Italy and in many EU countries, the last decade was characterized by a large development of distributed generation power plants. Their presence determined new critical issues for the design and management of the overall energy system and the electric grid due to the presence of discontinuous...

In this paper the climate change effect is an unforeseen earth temperature level above which a negative externality on technology and hence on society's welfare is exerted. We use a dynamic overlapping generations model to develop a positive analysis of the growth path of an economy with the...

At the start of the transition process in previously centrally planned economies the inflow of foreign capital was considered one of the main factors that allows the reduction of the economic and social costs of transformation. However, in practice, the role of foreign capital has appeared to be...

We deal with efficient allocation of the shut-down decision of a firm in which there is profit sharing. The paper can be considered as a complement to the literature on the endogenous ownership structure of the firm. We examine a variety of cases according to both different schemes of layoff...

Ecolabel award schemes have become increasingly popular. Their rationale is to enable (concerned) consumers to identify "green" products. By so doing, ecolabelling should stimulate environmental innovation, and induce firms to reduce the supply of conventional (polluting) products. Our analysis...

The paper studies the effect of scale economies on the optimal capacity adjustment of a mutiplant firm. It is shown that with increasing economies of scale plants are ranked in decreasing order, after which the optimal choice is to scrap the largest one. On the contrary, if there are decreasing...

The main issue is the organisation of firms when different degrees of labour participation are taken into account. We start reviewing the literature on the LM firm. We then consider a less radical labour participation, i.e. the Aoki firm. We survey extensions of the Aoki's firm to the case of...

When economic agents decide their optimal environmental behavior, they have to take into account non continuos evolutionary trends and irreversible changes characterising environmental phenomena. Given the still non perfect biophysical and economic knowledge, decisions have to be taken in an...
