The economic and environmental impact of trade in forest reserve obligations: a simulation analysis of options for dealing with habitat heterogeneity Rev. Econ. Sociol. Rural
Chomitz,Kenneth M.; Thomas,Timothy S.; Brandão,Antônio Salazar P..
A tradeable development rights (TDR) program focusing on biodiversity conservation faces a crucial problem: defining which areas of habitat should be considered equivalent. Restricting the trading scope to a narrow area could boost the range of biodiversity conserved but could increase the opportunity cost of conservation. The issue is relevant to Brazil, where TDR-like policies are emerging. Long-standing laws require each rural property to maintain a legal forest reserve (reserva legal) of at least 20%, but emerging policies allow some tradeability of this obligation. This paper uses a simple, spatially explicit model to simulate a hypothetical state-level program. We find that wider trading scopes drastically reduce landholder costs of complying with...

Impacts of the U.S. subsidy to soybeans on World prices, production and exports Rev. Econ. Sociol. Rural
Brandão,Antônio Salazar P.; Lima,Elcyon Caiado Rocha.
This paper specifies and estimates an econometric model of the soybean market (grain, oil and meal) to assess the effects of U.S. domestic support to soybeans on world soybean prices, production and exports. The model divides the world into five regions (modules): Argentina, Brazil, the European Union, the United States (US) and the Rest of the World (ROW). There are interactions between the modules through the international prices and the net exports of each soybean product. The international prices of grain, oil and meal are endogenous and are determined equating net exports of the first four modules (Argentina, Brazil, European Union and the U.S.) to net imports of the ROW. The analysis is conducted eliminating the U.S. domestic support to soybeans and...
