In this paper I focus on some important biological aspects of the forest management problem. I model a stochastically developing forest as a multidimensional, continuous-time Markov chain. Next, I pose three questions concerning the long-run characteristics of a stationary forest, the stochastic...

Economic models are meant to provide a framework to describe real-world economic activities. In principle, how well a model performs this task can be evaluated by how close the model’s simulated activities track the observed ones. A necessary .rst step in simulating a model is to choose values...

It is now recognized that the growth rate of per capita real income is not the only indicator of development. Development is a multidimensional oncept that focuses on development of human beings through removal of poverty, ill health, illiteracy, and other social deprivations. The observed...

I analyze the problem faced by an asymmetrically informed supranational governmental authority (SNGA) with limited financial resources who wishes to design an International Environmental Agreement (IEA). The SNGA cannot contract directly with polluting firms in the various LDCs, but he must deal...

There is general agreement that global warming is occurring and that the main contributor to this probably is the buildup of green house gasses, GHG, in the atmosphere. Two main contributors are the utilization of fossil fuels and the deforestation of many regions of the world. This paper...

We first review the literature pertaining to the protection of the modern sector in developing countries (DCs). We then discuss the nexuses between protection, economic dualism, and optimal environmental policy in DCs. Next, in the theoretical part of the paper, we construct a dynamic model of...

A multivariate technique called principal component analysis is used to combine measures of human development. The first principal component index is the linear combination of component indexes with maximal information content. This multivariate technique accounts for differences in the...

In this paper, we present a nonrenewable resource model including environmental pollution stock as a state variable to analyze the dynamic structure of an optimal tax. Based on the optimality conditions of our model, we showed that the optimal time path of the shadow cost of environmental...

The notion of a reservation value is a key feature of most contemporary dynamic and stochastic models of land development. It is clear that the magnitude of the reservation value has a fundamental bearing on the decision to develop or preserve land. This notwithstanding, many papers that analyze...

This paper builds a dynamic rational expectations model describing the supply of cattle. The theoretical model improves on existing models by allowing cow-calf operators to make period-by-period investment decisions on both the cow and calf margins, separates the markets for fed and unfed beef,...
