Prohibition and the Supply of Brazilian Mahogany
利用独特数据集研究巴西桃花心木采伐和贸易禁令的经济后果，发现禁令反而增加了供给并降低了非法商品价格，对毒品和濒危物种制品等非法市场有启示。
We use a unique data set to investigate the economic consequences of banning the harvest and trade of Brazilian mahogany. Because we find strong evidence that mahogany is smuggled out of Brazil as “other tropical species” through formal export mechanisms, we are able to construct a time series of quantities and implicit export prices covering both the periods before and after prohibition. Our finding suggests that a trade ban increases supply and makes the illegal good more affordable. Our analysis can offer important insights into other illegal markets, such as those for narcotics and products manufactured from endangered animal species. <i></i>
