The graphs below show demand for labor in two countries, A and B, and several vertical labor supply curves. Use these diagrams to answer the question about the effects of migration from one country to the other in search of a higher wage. Let the amount of migration (change in labor supply) be equal to the (identical) horizontal distance between the supply curves in both graphs. Country B Country A Se SB WB SA SA WA d PB h b a DA LB LA What is the effect of this migration on the welfare of workers who migrate? They gain area g They gain area (g+h+e) They gain area (a+b+c). O They gain area (g+h)

From the perspective of the destination economy, "Demand Pull” immigration generally results in (hint: draw a graph) more workers hired but wages could either increase or decrease with immigration. no change in wages nor workers hired. lower wages and more workers hired. higher wages and more workers hired.
