Rethinking the Gains from Immigration: Theory and Evidence from the U.S.

Recent influential empirical work has emphasized the negative impact immigrants have on the wages of U.S.-born workers, arguing that immigration harms less educated American workers in particular and all U.S.-born workers in general. Because U.S. and foreign born workers belong to different skill groups that are imperfectly substitutable, one needs to articulate a production function that aggregates different types of labor (and accounts for complementarity and substitution effects) in order to calculate the various effects of immigrant labor on U.S.-born labor. We introduce such a production function, making the crucial assumption that U.S. and foreign-born workers with similar education and experience levels may nevertheless be imperfectly substitutable, and allowing for endogenous capital accumulation. This function successfully accounts for the negative impact of the relative skill levels of immigrants on the relative wages of U.S. workers. However, contrary to the findings of previous literature, overall immigration generates a large positive effect on the average wages of U.S.-born workers. We show evidence of this positive effect by estimating the impact of immigration on both average wages and housing values across U.S. metropolitan areas (1970-2000). We also reproduce this positive effect by simulating the behavior of average wages and housing prices in an open city-economy, with optimizing U.S.-born agents who respond to an inflow of foreign-born workers of the size and composition comparable to the immigration of the 1990s

Does Religiosity Promote Property Rights and the Rule of Law?

Social and cultural determinants of economic institutions and outcomes have come to the forefront of economic research. We introduce religiosity, measured as the share for which religion is important in daily life, to explain institutional quality in the form of property rights and the rule of law. Previous studies have only measured the impact of membership shares of different religions, with mixed results. We find, in a cross-country regression analysis comprising up to 112 countries, that religiosity is negatively related to our institutional outcome variables. This only holds in democracies (not autocracies), which suggests that religiosity affects the way institutions work through the political process. Individual religions are not related to our measure of institutional quality

Technology Transfer Through Trade

This paper examines the role that trade plays in economic development through the channel of technology transfer, approximated by total factor productivity. Three strains of factors influence the process of technology transfer; direct effort that is taken to transfer technologies, the capacity to adopt technologies, and differences in the underlying conditions between donor- and receiving countries. In this context, trade in (capital) goods allows technology import and improved input decisions. Second, trade opens export markets, allowing learning-by-doing. Third and most importantly, trade increases the set of accessible technologies, increasing the scope for imitation. The theoretical insights are compared to the empirical literature that deals with trade and technology transfer. Not surprisingly, it turns out that openness and human capital have a positive influence on the transfer of technology. Yet methodological problems with the data weaken the practical significance of the results, especially as the precise and fundamental mechanism of spillovers and the factors that condition the degree of technology transfer are not profoundly illuminated. These underlying processes have to be better understood in order to be able to give valuable policy recommendations that will go beyond the general advice of increasing openness and human capital formation
