This paper studies groundwater management in the presence of rainwater harvesting (RWH). We propose a two-state model that takes into account the standard dynamics of the aquifer and the dynamics of the storage capacity and we assume that the collection of rainwater reduces the natural recharge....

Migrants' remittances should b e considered as one of the determinants of migration ows, since they have an economic impact on recipient economies, and can play a signaling role concerning the actual economic conditions in countries. In b oth cases, the decision to migrate may b e interpreted as...

This paper is concerned with groundwater management issues in the presence of rainwater harvesting (RWH). Namely, we propose a two-state model in order to take into account the standard dynamics of the aquifer and the dynamics of the storage capacity since the collected rainwater reduces the...

This paper tackles the increasingly significant problem of irrigation-induced soil salinity within a groundwater management model. Irrigation can result not only in heavier salt concentrations, but also in the removal of salt from the soil through return flows. Given these contradictory...

Rainwater harvesting, consisting in collecting runoff from precipitation, has been widely developed to stop groundwater declines and even raise water tables. However this expected environmental effect is not self-evident. We show in a simple setting that the success of this conjunctive use...

There are more and more industries in which firms are specialized in the production of a component of the final good. This is especially true in high-tech industries. The basic question is why don't these firms merge ? We paradoxically show that industries which are typical candidates for...

In this paper, the reaction of firms to the introduction of environmental charges in a given industry is analysed. Firms may decide either to relocate their plants abroad or to adopt a new environmental-friendly technology. The latter can be either developed by investing in R&D or obtained by...
