Payments for eco-system services and nature (words are used synonymously) cannot be treated independently from spatial outlays. We adopt a modified "von Thünen" framework and ask for optimal land allocation in space in case of land rent change and regional preference. Yet, our approach is not...

This paper introduces a method for solving numerical dynamic stochastic optimization problems that avoids rootfinding operations. The idea is applicable to many microeconomic and macroeconomic problems, including life cycle, buffer-stock, and stochastic growth problems. Software is provided.

This paper aims to analyze the increasing issue of overcongestion affecting the immigration hosting facilities of many Italian municipalities, as well as the heterogeneity in immigration regulatory behavior emerging among the latter. Since 2014, the immigration rate in Italy has tripled and the...

It is well known that the forestry sector is sensitive to climate change but most studies have examined impacts only through 2100 and warming of less than 4°C. This is the first timber analysis to consider possible climate change impacts out to 2250 and warming up to 11°C above 1900 levels....

This paper addresses the spatial evolution of countries accounting for economics, geography and (military) force. Economic activity is spatially distributed following the AK model with the output being split into consumption, investment, transport costs and military (for defense and expansion)....

Our paper explores the optimal investment in integrative technologies (such as command and control systems), which are a major part of defense R&D at the beginning of the 21st century. Employing a dynamic optimization framework, we find that under linear development costs, it may be optimal or...

A dynamic model is developed to analyze farmers' irrigation investment and crop choice decisions under alternative water quality protection policies. The model is applied to an empirical example in the Oklahoma High Plains. The choices of crops and irrigation systems and the resulting levels of...
