Most of the literature on how immigration affects the labor market focuses on the outcomes of natives in direct competition with immigrants. This paper reviews a growing literature on an alternative channel. Immigrants, particularly low-skilled women, are disproportionately represented in the household services sector, a global phenomenon that is seen to some extent in most regions. A simple time-use model suggests that by lowering the price of market-provided household services, immigrant workers allow high-skilled native women to reduce their unpaid household production and increase their participation in the labor market. I review existing evidence that the presence of foreign domestic workers has increased the labor supply of high-skilled native women, has helped narrow the gender earnings gap in high-paying powered occupations, and that these advances have not come at the cost of native women investing less time in their children or having lower birth rates. I discuss the policy implications of these results, as well as some ethical considerations.

In the last decade, Gulf countries have imposed hiring quotas to promote the participation of natives in the private sector and address high levels of unemployment, particularly among women and the youth. This paper explores how one such policy, Nitaqat in Saudi Arabia, affected the outcomes of exporting firms, the most productive sector of the non-oil economy. We find that whereas the policy was successful in increasing the employment of Saudi nationals by these firms, it came at a high cost. In the year following the announcement of the policy, relative to firms above the quota, firms below the quota were 1.5 percentage points more likely to exit the market, 7 percentage points less likely to export, and conditional on exporting, the value of their exports fell by 14 percent. Additionally, surviving treated firms reduced their labor force by 10 percent. We find that to comply with the policy, firms hired mostly lower-wage, low-skilled Saudis. The policy doubled the share of women in treated firms. Importantly, we find that these short-term effects persisted for at least three years after the policy's implementation.

This paper investigates gender differences in the job search process, both in the field and lab. First, we collect rich information on initial job offers and acceptances from undergraduates of Boston University's Questrom School of Business. We document two novel empirical facts: (1) there is a clear gender difference in the timing of job offer acceptance, with women accepting jobs substantially earlier than men, and (2) there is a clear gender earnings gap in accepted offers, which narrows in favor of women over the course of the job search period. To rationalize these patterns, we develop a job search model that incorporates gender differences in risk aversion and over-optimism about prospective offers. We validate the model's assumptions and predictions using the survey data, and present empirical evidence that the job search patterns in the field can be partly explained by the greater risk aversion displayed by women and the higher levels of over-optimism displayed by men. Next, we replicate the findings from the field in a specially-designed laboratory experiment that features sequential job search, and provide direct evidence on the purported mechanisms. Our findings highlight the importance of risk preferences and beliefs for gender differences in job-finding behavior, and consequently, early-career wage gaps among the highly-skilled.
