Is there a minimum wage biting in Puerto Rico? Updating the debate
研究了2007至2009年波多黎各最低工资上调至7.25美元对就业的影响，发现仅少数小行业就业受负面冲击，且产出对就业影响更大。
Abstract This research evaluates the repercussions on employment in Puerto Rico of the latest increases in the minimum wage (made between 2007 and 2009). We find that the increases in the minimum wage to $7.25 had a negative impact on employment in a few small sectors only, and that employment was significantly more affected by output.
