This paper presents a framework to determine optimal resource allocation over time for the production of a good by heterogeneous producers who generate a stock externality. We analyze the optimal intertemporal and quality-specific combination of abatement strategies at the source given by a...

In 2010 implementation of the European Higher Education Area in European universities will imply a rethinking of the structure of subjects taught and a likely reduction in the content of many current teaching programmes. This will be the case in quot;Mathematics for Economistsquot; and will...

Different regulatory bodies tend to develop environmental policies not recognizing the interdependencies between externalities. For example, one authority may regulate a stock pollution and another a flow pollution that result from the same activity. This study introduces a two-phase...

The Escalator Boxcar Train method is used to solve the distributed optimal control problems of forest management numerically. It takes into account intraspecific competition for scarce resources such as light, space, and nutrients during reproduction, growth, and mortality. It provides an...

We derive optimal input taxes to control stock pollution problems generated by heterogeneous agents. The taxes vary over time and in response to differences of asset quality and technology choice. We also derive second-best policies and compare them to the efficient policy and also among...

In addition to exacerbating water scarcity, climate change is expected to lead to an increase in the frequency and magnitude of droughts. During an extreme water shortage, economic agents may find it difficult to modify their production structure immediately, and will therefore try to maintain...
