We find that the conditional wage‐gap for non‐whites is negatively related to gross domestic product per worker across the US. To explain this, we develop a model linking unequal access to employment with the wage gap, labor misallocation, and income loss. The presence of underprivileged workers allows inefficient firms to co‐exist with efficient ones and leads to skill misallocation, higher unemployment and lower output. Calibrating the model to match the US, we find a fall in market‐based racial discrimination renders inefficient firms non‐profitable, causing reallocation of labor and a positive effect on income as high as 4 percent when discrimination is eliminated.

We investigate the effects of U.S. immigration in a comprehensive search and matching framework that allows for skill heterogeneity, imperfect substitutability between skilled and unskilled inputs, different search cost between natives and immigrants, cross‐skill matching, and imperfect transferability of foreign human capital. When we simulate the effects of the U.S. immigration that took place between the years 2000 and 2009, we find that both skilled and unskilled natives, as well as skilled and unskilled immigrants, gain in terms of income and employment. We also investigate the effects of an improvement in the transferability of human capital across borders and find that, although it has some redistributive effects, overall it benefits both immigrants and natives.

In a two-period overlapping-generations model with production, we consider the damaging impact of environmental degradation on health and consequently life expectancy. Despite the presence of social constant returns to capital, which would otherwise generate unbounded growth, when pollution is left unabated, the economy cannot achieve such a path. Instead, it converges either to a stationary level of capital per worker or to a cycle in which capital per worker oscillates permanently. The government's involvement in environmental preservation proves crucial for both short-term dynamics and long-term prospects of the economy. Particularly, an active policy of pollution abatement emerges as an important engine of long-run economic growth. Furthermore, by eliminating the occurrence of limit cycles, pollution abatement is also a powerful source of stabilization.

We analyze the impact of the U.S. skill‐biased immigration influx that took place between 2000 and 2009 within a search and matching model that allows for skill heterogeneity, differential search cost, and capital‐skill complementarity. We find that although the skill‐biased immigration raised the overall net income to natives, it had distributional effects. Specifically, unskilled native workers gained in terms of both employment and wages. Skilled native workers, however, gained in terms of employment but lost in terms of wages. Nevertheless, in an extension where skilled natives and immigrants are imperfect substitutes, even the skilled wage rises.
