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...

One of the reasons why workers' enterprises (WE) still represent a relevant chunk of the economy may lay in some affinities with conventional profit-maximizing firms. To provide a solid basis to this presumption, we compare the entry policies of WEs and conventional firms when size is set at...

In many cases consumers cannot observe firms' investment in quality or safety, but have only beliefs on the average quality of the industry. In addition, the outcome of the collective investment game of the firms may be stochastic since firms cannot control perfectly the technology or external...

This article studies the effects of tax competition on the provision of public goods under business risk and partial irreversibility of investment. As will be shown, the provision of public goods changes over time and also depends on the business cycle. In particular, under source-based...
