We investigate the effects of immigrants on the economy comprised of substitute and complement industries when immigrants do not have complete information about their employers．For this purpose, we assume that wages are determined according to the efficiency wage hypothesis and that immigrants are substitutes for native workers in the substitute industry and complements to native workers in the complement industry．We also assume that immigrants do not know their working hours exactly．We show that it is likely that in the substitute (complement) industry native worker utility increases (decreases) and the profit of the firms decreases (increases) as more immigrants are accepted． These results are contrasted with those derived when there is no asymmetry of information between firms and immigrants. In other words, when information is symmetric, the native worker utility becomes lower (higher) and the profit of the firms becomes larger (smaller) in the substitute (complement) industry with increases in the number of immigrants．Our results suggest that even in the case where immigrants do not have complete information, the conflicting relation of interests between native workers and firms are affected by the availability of information as well as by the relation of native workers and immigrants as factors of production.
