This study theoretically investigates the economy of a small country that exports skilled labor to higher developed countries and simultaneously imports unskilled labor from lower developed countries. Compared with the free immigration case, if this country adopts an optimally controlled immigration policy by imposing income tax on immigrants to maximize national income, skills formation is negatively affected and the number of domestic unskilled workers increases. Moreover, under certain conditions, we can assert the counter-intuitive possibility that the wage rate of domestic unskilled workers may decrease but that of skilled workers may increase owing to the restriction of foreign unskilled workers.

Abstract.   In the developed countries some native workers are unemployed while there exist illegal unskilled (legal skilled) foreign workers who are complementary to (substitutable for) natives and their wages are usually lower than (equal to) that of natives. Reflecting this situation, we introduce two types of immigrant in an efficiency wage model. It is shown that domestic government should exclude illegal foreign workers but welcome legal ones if the total number of illegal immigrants is small enough and well controlled. On the other hand, legal immigration should be restricted if the flood of illegal immigration is out of control.

Differences in environmental regulation between rich and poor countries have caused a geographical relocation of polluting industry from the former to the latter. In several cases the reduction in domestic emissions is at least partly compensated by an increase in trans-boundary pollution which is detrimental to the productivity of environmental sensitive sectors (such as agriculture) industry in a developed country. Can a government in a rich country try to correct the negative consequences of trans-boundary pollution when mechanisms such as binding international agreements are difficult to implement? In this paper we build a simple North-South model of trade where the manufacturing plants are completely outsourced in a developing country and we analyze the effects of a subsidy program to pollution abatement industry located in the North. We find that, contrarily to common intuition, the subsidy to the pollution abatement equipment industry might reduce welfare in the North when the efficiency of the pollution abatement technology is already relatively high and when the wage gap between the North and South is high. In addition we find that international migration might have a positive impact on improving the environmental stock and welfare in the North and might be a more efficient and less distortive way to address the trans-boundary externality.
