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...

We provide a general framework in which to determine the optimal penalty fee inducing the contractor to respect the contracted delivery date in public procurement contracts (PPCs). We do this by developing a real option model that enables us to investigate the contractor’s value of investment...

This paper tries to explain why most migration flows show some observable jumps in their processes, a phenomenon that seems to be sympathetic with the characteristic of irreversibility of migration. We present a real option model where the choice to migrate depends on both the differential wage...

Recent European Legislation on immigration has revealed a particular paradox on migration policies. On one hand, the trend of recent legislation points to the increasing closure of frontiers (OECD 1999, 2001, 2004), also by using immigration quotas. On the other hand, there is an increase of...

The paper analyses the timing of spontaneous environmental innovation when second-mover advantages, arising from the expectation of declining investment costs, increase the option value of waiting created by investment irreversibility and uncertainty about private payoffs. We then focus on the...

To avoid the extremely high profit levels found in recent experiences with price cap regulation, some regulators have applied a profit-sharing (PS) rule that revises prices to the benefit of consumers. This paper investigates the conditions under which a regulator can implement such a PS scheme,...

When assigning a concession contract, the regulator faces the issue of setting the concession length. Another key issue is whether or not the concessionare should be allowed to set the timing of new invest- ments. In this paper we investigate the impact of concession length and investment timing...

We analyse the effects of different regulatory schemes (price cap and profit sharing) on a firm's investment of endogenous size. Using a real option approach in continuous time, we show that profit sharing does not delay a firm's start-up investment relative to a pure price cap scheme. Profit...

Il presente lavoro propone uno strumento di valutazione degli inves- timenti nel servizio idrico integrato (Legge 36/94) in grado di rendere esplicita la dimensione strategica dei progetti in espansione di capac- ità produttiva. In un contesto contrattuale in cui il Piano d'Ambito preveda una...
