Moreover, trade liberalization helps developing countries gain access to foreign markets in advanced countries, as illustrated by the fact that the United States, through free-trade agreements, has been more willing to lower tariffs for countries such as Mexico and Chile if they do the same for the United States.
Empirical evidence indicates that trade liberalization has positive effects on productivity and economic growth for both importing and exporting countries: It has even been found to be associated with morerapid increases in life expectancy and a reduction in infant mortality.
