In the last two decades in the OECD countries there have been a raising development of firms certified as Social Responsible (CSR is the acronym of Corporate Social Responsibility). This kind of certification is assigned by private companies that guarantee that the behaviour of a certain firms...

In this paper we apply a real-option model to study how tax rate uncertainty affects a firm's decisions about both the timing and the source of finance of an investment project. We show that debt finance (i) encourages entry and (ii) mitigates the e¤ect of tax rate uncertainty on entry timing.

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...

This work is devoted to study the role of combined entry and exit strategies in the migration process. It develops a real option model in which the community of immigrants in the host country is described as a club and the immigrant’s benefits is a U-shaped function, depending on the dimension...

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...

In this paper, we present a theorethical model that tries to investigate the observable hysteresis process in the migration dynamic. In the model the migration choice depends not only on the wage differential, but also on a U-shaped benefit function of a community of homogenous ethnic...
