This chapter reviews academic research on the connections between agglomeration and innovation. We first describe the conceptual distinctions between invention and innovation. We then describe how these factors are frequently measured in the data and some resulting empirical regularities....

In 2011, a reform in the United Arab Emirates allowed any employer to renew a migrant's visa upon contract expiration without written permission from the initial employer. We find that the reform increased incumbent migrants' earnings and firm retention of these workers. This occurs despite an...

The cross-national intragenerational income mobility literature assumes within-country mobility is invariant over the period measured. We argue that a great social transformation--German reunification-- abruptly and permanently altered economic mobility. Using standard measures of mobility (with...

We explore the hypothesis that high home-ownership damages the labor market. Our results are relevant to, and may be worrying for, a range of policy-makers and researchers. We find that rises in the home- ownership rate in a U.S. state are a precursor to eventual sharp rises in unemployment in...

It is often argued that informal labor markets in developing countries promote growth by reducing the impact of regulation. On the other hand informality may reduce the amount of social protection offered to workers. We extend the wage-posting framework of Burdett and Mortensen (1998) to allow...

Two facts motivate this study. (1) The United States is the world's most productive economy. (2) The US is the destination for a broad range of net factor inflows: unskilled labor, skilled labor, and capital. Indeed, these two facts may be strongly related: All factors seek to enter the US...

In this paper, we estimate matching functions using disaggregate data. We find strong support for the matching approach, with most specifications implying slightly increasing returns to scale. This finding does not appear to arise from our inclusion of additional controls or from the level of...

Shimer's calibrated version of the Mortensen-Pissarides model generates unemployment fluctuates much smaller than the data. Hagedorn and Manovskii present an alternative calibration that yields fluctuations consistent with the data, but this has been challenged by Costain and Reiter, who say it...

Using new survey data from Mexico, a dynamic econometric model is estimated to test the effect of policy changes on the flow of migrant labor from rural Mexico to the United States and test for differential effects of policy changes on male and female migration. We find that both IRCA and NAFTA...

This paper examines how the Internet has impacted job search behavior. Examining those who use the Internet for job seeking purposes, I show that the vast majority are currently employed. These employed job seekers are more likely to leave their current employer and are more likely to make an...
