We develop a new partial equilibrium, four-region world trade model for the soybean complex comprising soybeans, soybean oil, and soybean meal. In the model, some consumers view genetically modified Roundup Ready (RR) soybeans and products as weakly inferior to conventional ones; the RR seed is...

Planned introductions of genetically modified crop varieties can be troublesome to model. Estimation of demand and supply equations is not feasible due to lack of data. Further, specifying demand and supply equations requires calibration to a presumed equilibrium. Depending on the point chosen,...

Despite the clear influence of European Union biotechnology restrictions on trade patterns, very little work has been done to model these influences or their long-run effects. This paper presents an economic trade theory model of biotechnology, biotechnology research and development (R&D), and...

Non-price competition is increasingly important in world food markets. Recently, the expression export sophistication has been introduced in the economic literature to refer to a wide set of attributes that increase product value. An index has been proposed to measure sophistication in an...

The global market for agri-food products has been divided for a decade. The division arose over the approval of biotechnology-based innovations – with the European Union temporarily suspending approvals and imports until it could devise a new approval mechanism. Other countries chose between...

The article discusses processes of validating structural forecasting models It summarizes methods of evaluating the goodness of fit of model Simulations over historical periods and methods of comparing the forecasting behavior of structural models with that of Simple time series models The net...

Convergence in per capita income turns on whether technological knowledge spillovers are global or local. Global spillovers favor convergence, while a geographically limited scope of knowledge diffusion can lead to regional clusters of countries with persistently different levels of income per...

Member nations of the World Trade Organization are permitted to develop regulations that might restrict trade if they do so for the purpose of protecting human, animal or plant life or health. The regulations, under both the Sanitary/Phytosanitary and Technical Barriers to Trade agreements, must...
