We comment on four aspects of Albers' [1] model of ecological constraints on tropical forest management. Albers structures her model in a highly asymmetric manner, with strong, uniform biases against development and in favor of preservation. Despite Albers' repeated claims that her model is...

There is general agreement that global warming is occurring and that the main contributor to this probably is the buildup of green house gases, 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 use GIS and econometric methods to estimate the marginal implicit values of environmental amenities associated with residential land parcels in the mountain town of Logan, Utah. Amenities include proximity to open spaces (such as parks, golf courses and lakes), commercial zones, major roads,...

We present a numerical version of the specific factors model of production/trade in a small economy, built in Excel. The model features the most common graphical devices used to explain the model properties. It differs from earlier work in that the solution is embedded in the sheet, making the...

We use computable general equilibrium methods to examine the impact that agricultural trade reform under the Doha agreement would have on the Indian economy, in particular on household level welfare. The GTAP model is used to simulate the effect of the latest proposed modalities on the global...

This paper presents a series of topics in international trade theory and how they can be implemented using GAMS. The paper will be updated periodically as new topics are completed.

This paper examines how a regulatory authority might subsidize (i.e., cost share) the partici- pation of associations (or teams) of agents in a surplus-generating economic activity, and how the agents might in turn cooperatively share the surplus. Toward this end, a subgame-perfect equilibrium...

This paper applies two recently developed trading algorithms to a water quality trading (WQT) market located in the Cub River sub-basin of Utah; a market that includes both point and nonpoint sources. The algorithms account for three complications that naturally arise in WQT markets: (1)...
