| New advances in biotechnology have enhanced production of maize, soybeans, and cotton. Consumer reactions to the new technology have been mixed. Both the supply shock, from an increase in productivity or a reduction in input use, and the demand shock, which is determined by the consumer response to consuming GM foods, affect production, trade, and prices of GM foods. In this paper, we survey models that analyze the market effects of GM technology. The results depend on a number of important issues such as the cost of market segmentation and labeling, the nature of the productivity shock to producers of GM products, and the extent of any adverse reaction to GM products by consumers. The results from global trade models indicate that, if costs of labelling... |

| This paper analyzes price, production and trade consequences of changing consumer preferences regarding the use of genetically modified organisms (GMOs) in food production. The analytical framework used is an empirical global general equilibrium model, in which the entire food processing chain – from primary crops through livestock feed to processed foods – is segregated into genetically modified (GM) and non-GM lines of production. This model is used to analyze the implications of widespread use of genetically engineered crops in some regions whilst consumers in Western Europe and High- income Asia adopt a critical attitude toward GM foods. Two different representations of consumer preference changes are illustrated: (1) a change in price sensitivity:... |

| This paper documents the construction of social accounting matrices (SAMs) for Vietnam for 1996 and 1997. The data sources used to construct the SAMs include national accounts statistics, government budget data, the official 1996 input-output table, the 19 97/98 Vietnam Living Standards Survey (VLSS), and COMTRADE trade data. The agri-food sectors are particularly well represented in the SAMs: the resulting VIETSAM includes 97 producing sectors with eight agricultural sectors, two agricultural service sectors and 13 food processing industries. In terms of institutional detail, the SAMs include five factors of production (three types of labor distinguished by skill level, one type of capital and one type of land), six household types (distinguished by... |
