This paper provides examples of both parametric and non-parametric tests for economies of scale in the control of non-point pollution. Because field-level control costs and control effectiveness are uncertain from the regulator's perspective (due to the existence of asymmetric information), we...

We present a numerical version of the factor proportions (Heckscher-Ohlin-Samuelson) model of production 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...

This paper was presented at the INTERNATIONAL TRADE IN LIVESTOCK PRODUCTS SYMPOSIUM in Auckland, New Zealand, January 18-19, 2001. The Symposium was sponsored by: the International Agricultural Trade Research Consortium, the Venture Trust, Massey University, New Zealand, and the Centre for...

Although the overall economic performance of economies in South Asia in recent years has been impressive, there is concern that an aging and increasingly inadequate infrastructure may limit the potential for further growth and economic development. A critical infrastructure component is the...

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...

A handbook for trade indices and indicators

We present a simple simulation model, implemented in Excel, that can be used to develop the concept of optimal tariffs, and as the basis of an experimental assignment on the effects of tariff retaliation. By exploring the simulation, students are able to discover for themselves the potentially...

Using information from on-line graded assignments in an intermediate microeconomics course, we find that non-procrastinators (both early-starters and front-loaders) obtain higher scores than their dillydallying counterparts. We also find that while busier students tend to start their assignments...

In the past twenty years the growth of China's economy and agriculture has been extraordinary. However it seems unlikely that, without substantial interventions, China will attain self-sufficiency in agriculture by 2005. We build a CGE model to examine the main trade policy options available to...
