Assuming a small open economy where wages are determined by the efficiency wage hypothesis, we investigate how the changes in the foreign worker quota affect native worker employment, wage and expected lifetime utility. For this purpose, we assume that the foreign worker quota is smaller than the number of foreign workers who are willing to migrate to the small open economy. We also assume that the per capita effective labor force of native workers is larger than that offoreign workers. We show that even if the foreign worker quota is small, increases in the quota reduce native worker employment, since increases in labor demand are smaller than those in the quota. On the other hand, increases in the foreign worker quota have ambiguous effects on native worker wage. This is because native worker wages increase with increases in labor demand, whereas unemployed native workers become less likely to be employed, leading to lower native worker wage that satisfies their non-shirk condition. The sum of the native worker expected lifetime utilities decreases with increases in the quota, since increases in the quota reduce the per capita expected lifetime utility of native workers and the per capita expected lifetime utility of employed native workers is larger than that of unemployed native workers.
