Article dans une revue: This paper examines the effects of stricter environmental regulation on income distribution and welfare for an open economy with inbound tourism. The pollution input is considered as a mobile factor between sectors, and a decrease in it lowers wages of skilled labor in the traded sector but can increase the wages of unskilled labor in the non-traded sector. A stricter policy on environmental controls can narrow wage inequality and increase welfare if the tourism terms-of-trade effect dominates. These results are confirmed by simulations.
