Presenting an economic perspective of deforestation in the Brazilan Amazon, this study utilizes economic and ecological data from 1970 to 1996. It examines the extent to which land clearing promotes economic activity and growth and analyzes policies such as road building and subsidized credit. It explores whether the economic benefits of land clearing surpass the ecological costs and considers the viability of extractivism as an alternative to deforestation.

The Internet stimulates trade. Using a gravity equation of trade among 56 countries, we find no evidence of an effect of the Internet on total trade flows in 1995 and only weak evidence of an effect in 1996. However, we find an increasing and significant impact from 1997 to 1999. Specifically, our results imply that a 10 percent increase in the relative number of web hosts in one country would have led to about 1 percent greater trade in 1998 and 1999. Surprisingly, we find that the effect of the Internet on trade has been stronger for poor countries than for rich countries, and that there is little evidence that the Internet has reduced the impact of distance on trade. The evidence is consistent with a model in which the Internet creates a global exchange for goods, thereby reducing market-specific sunk costs of exporting.
