Suppose labor demand for low-skilled workers in the United States is w = 24 - 0.1L where L is the number of workers (in millions) and w is the hourly wage. There are 120 million domestic U.S. low-skilled workers who supply labor inelastically. If the U.S. opened its borders to immigration, 20 million low-skilled immigrants would enter the U.S. and supply labor inelastically. Draw a clearly labeled graph showing the equilibrium before immigration and the effect of opening the borders....
