In this paper we consider a simple intertemporal economy in which immigrants, if admitted, bring heterogeneous amounts of capital. We show that under certain conditions there is a level of immigration which maximizes the economy's capital-labor ratio, and that this level of immigration is the...

We study economies where improving the quality of institutions – modeled as improving contract enforcement – requires resources, but enables trade that raises output by reducing the dispersion of marginal products of capital. We find that in this type of environment it is optimal to combine...

Previous research has reached mixed conclusions about whether higher levels of immigration reduce the wages of natives. This paper reexamines this question using data from the Current Population Survey and the Immigration and Naturalization Service and focuses on differential effects by skill...

Conventional VAR estimation and forecasting ignores the fact that economic data are often subject to revision many months or years after their initial release. This paper shows how VAR analysis can be modified to account for such revisions. The proposed approach assumes that government...

The nature of yield curve dynamics and the determinants of the integration order of yields are investigated using a benchmark economy in which the logarithmic expectations theory holds and the regularity condition of a limiting yield and limiting term premium is satisfied. By considering a...

Since the early 1990s, NAIRU estimates have declined and unemployment duration has risen relative to the unemployment rate. These developments may have arisen from the aging of the workforce or practices reducing job turnover. We assess the internal consistency of these hypotheses using...

Border crime rates lie consistently below the national average. In the 1990s, however, while there as a large decline in property-related crime along the U.S.-Mexico border, violent crime rates began to converge to the national average. At the same time, legal and illegal immigration from Mexico...

Lower mutual fund loads have plausibly boosted the stock wealth elasticity of U.S. consumption by enhancing stock liquidity and arguably by inducing stock ownership among middle-income families, consistent with theory and cross-section data (Guiso, Haliassios, and Jappelli (2003), Haliassios...
