My research agenda has focused upon the skills and composition of the American workforce, with an emphasis on the causes and consequences of immigration. Though my initial work adopted a macroeconomic perspective, I have increasingly borrowed insights and tools from labor economics, urban economics, international trade, and public economics.

Interests

Immigration
My work explores the causes and consequences of U.S. immigration, usually distinguishing between workers of differing levels of educational attainment. Among workers with little educational attainment, my co-authors and I have found that although short-run GDP fluctuations pull immigrants into particular states, trend GDP is more important for pushing migrants out of their home countries. Importantly, we do not find evidence that such immigration reduces wages or pushes natives to move to new states in search of better labor market opportunities. Instead, our research notes that less-educated native and foreign-born workers are employed in strikingly different occupations. Natives specialize in communication-intense work, while immigrants specialize in manual labor. This helps natives to effectively protect themselves from competition with immigrants. Immigration induces natives to increasingly specialize in higher-paying communication occupations so that wage losses from immigration are small.

In studying the market for highly educated labor, my co-authors and I have primarily concentrated on the consequences of the H-1B program, which grants temporary work permits for skilled workers. We find that by restricting temporary skilled immigration, the United States has also reduced the quality of international students considering a U.S. education. This effect is largely driven by a decline in the number of students from the top quintile of the ability distribution. In more recent work, we argue that the H-1B program has increased the productivity of the U.S. workforce and wages paid to college-educated natives without decreasing wages paid to non–college-educated workers.

Racial Diversity
Though I do not have any current projects examining the effects of racial diversity, my dissertation explored whether racial diversity has positive or negative effects on economic outcomes in the United States. My interest in this topic began in my primary field of specialization in graduate school — economic growth. I was motivated by well-known cross-country growth studies arguing that diversity impedes economic development. I felt that those papers missed an important issue — that diversity could have heterogeneous effects across economies.

My dissertation found that the U.S. experience differs from that of other countries. City-level analysis indicates that racial diversity generates economic gains in the form of higher wages. Evidence at the state level is ambiguous, however, as results depend upon the specific econometric technique used. The effects of diversity also vary across sectors of the economy. Industries employing a large number of workers responsible for creative decision making and customer service experience gain from diversity, while industries characterized by high levels of group effort suffer losses. In this sense, my research has helped reconcile two competing literatures by suggesting that diversity improves decision making and problem solving, but also encumbers common action and public goods provision.
