Nitrate pollution from agriculture is an important environmental problem, caused bythe excessive use of inorganic fertilizers. The internalization of this externality, via a tax onmineral nitrogen, could lead to a second best solution, reducing nitrate emissions. Severalauthors suggest that a...

We analyze the current state and future requirements of an agricultural income stabilization mechanism in a transition country – namely, the crop insurance system in Kazakhstan. Three objectives will be pursued: First, factors influencing the development of the crop insurance market will be...

A mathematical programming model is developed and associated to a spatial pattern index (Ripley L function) to analyse the optimal reserve design and implementation for the Little Bustard conservation in Plaine de Niort. The model structure corresponds to three spatial levels, fields, farm and...

The biological nature of agricultural production processes induce a higher degree ofuncertainty surrounding the economic performance of farm enterprises. This has contributedto the development and acceptance of forms of public intervention aimed at reducing incomevariability that have no...

A water-crop simulation/mathematical programming model of irrigation water demand in northeastern Colorado is formulated to develop an original concept of derived demand for consumptive use of water. Conventional demand functions for water deliveries are also developed, and the effect of...

Recently, Branzei, Dimitrov, and Tijs (2003) introduced cooperative interval-valued games. Among other insights, the notion of an interval core has been coined and proposed as a solution concept for interval-valued games. In this paper we will present a general mathematical programming algorithm...

"The common-property literature has often focused on the question of efficiency. Here we consider distributional issues instead. How should the benefits of the commons (say, a fishery) be distributed? We approach the question from the viewpoint of ownership rather than income redistribution. "A...

"Institutional approaches to social dilemmas have so far focused on how to create incentive structures that channel individuals' behavior into socially desirable outcomes assuming that everyone is selfish. However, the presumption of universal selfishness is not only empirically invalid but may...
