From 1997 to 2001 we observe in the Usa a faster growth in the number of Nonemploye firms (NF) vis à vis Employer firms (EF). The diverse speed of net entry may be due to particular internal organisation of the two types of firms and the effect that this has on the reactions to market...

In this paper stochastic dynamic programming is used to investigate land conversion decisions taken by a multitude of landholders under uncertainty about the value of environmental services and irreversible development. We study land conversion under competition on the market for agricultural...

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 paper stochastic dynamic programming is used to investigate habitat conservation by a multitude of landholders under uncertainty about the value of environmental services and irreversible development. We study land conversion under competition on the market for agricultural products when...

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...

In a stochastic dynamic frame, we study the technology choice problem of a continuous co- digestion biogas plant where input factors are substitute but need to be mixed together to provide output. Given any initial rule for the composition of the feedstock, we consider the possibility of...
