We evaluate the effects of climate change on Vietnam's rice market. Results suggest that under a low-emission scenario and without interventions, rice production would drop by as much as 18% by 2030 relative to the 1980–1999 average. Farm and wholesale prices would increase by 1.86%, causing domestic demand to fall by 0.38%. The export sector would experience a rise of 6.94% in export free-on-board prices and a drop of 55.36% in export quantities. Farmers would experience a sales loss of 16.02%, whereas wholesalers would see a sales gain of 1.48%. For exporters, their sales loss would amount to 48.42%.

There is often a need to respond quickly to assess the likely implications of policy changes. Here, an equilibrium displacement model is adapted to study international bans on U.S. beef. An equilibrium displacement model offers a convenient way of quickly predicting the effects of supply and demand shocks. The equilibrium displacement model used here has an international sector, which allows the study of issues that past models with only a domestic sector could not. The estimated welfare loss of U.S. beef producers, due to both Japanese and South Korean bans after the discovery of bovine spongiform encephalopathy (BSE) in the United States, is $565.31 million.
