We report on research that concerns the education and training people receive, the amount that they work, what they do, and what they earn. The specific topics are too many to list. Here are a few.

• Unemployment
• The wage and employment response to unemployment insurance, disability insurance, and income taxes and transfers
• School quality, educational attainment, and economic outcomes
• Regulations governing minimum wages, overtime pay, hiring and firing, and collective bargaining
• Discrimination in employment and pay
• The labour market effects of immigration
• The decision to retire
• Inequality and intergenerational mobility
• Marriage, fertility, and labour market behavior

How tax rates influence the migration of superstar inventors

This paper shows that taxes affect the international location decisions of the best “superstar” inventors. Higher tax rates lead to a significantly lower share of superstar inventors remaining in their home country and a lower share of foreign superstar inventors who move to the country. This may have significant fiscal and innovation costs for a country that should be taken into account when setting tax policy.

Does welfare inhibit success? The long-term effects of removing low-income youth from the disability rolls

Despite the controversy surrounding welfare programs, there is little empirical evidence about the long-term effects of these programs on recipients. In a recent paper, Deshpande (2016), I study the long-term effects of removing low-income youth from a large cash welfare program, using a policy change from the 1996 welfare reform law. I find that youth who are removed from welfare have low earnings and minimal earnings growth in adulthood. The results indicate that this welfare program does not substantially inhibit success and self-sufficiency among youth.

Studying advanced mathematics: the potential boost to women’s career prospects

Why are there so few women in highly paid careers as chief executives and, more generally, in finance, business, science, technology, engineering and mathematics? Analysing Danish data on young people whose educational and professional lives have been tracked over two decades since they started high school, this research suggests that part of the reason lies in restrictive bundling of courses, which deters talented young women from acquiring advanced mathematical skills. Changing the learning environment and designing the curriculum to identify and foster young women with high mathematical abilities would attract more of them and help to reduce the gender pay gap.

Why small isn’t always beautiful: labor regulations and firm growth

Regulations often have unintended costs as well as intended benefits. France has a large number of labor market regulations that bind when a firm has 50 or more employees. These regulations are intended to help workers, but they also act as a tax on large firms. This discourages firms near the threshold from growing larger and producing more output. We calculate that these French labor regulations depress overall economic output by over 3%.

The gender wage gap: how firms influence women’s pay relative to men

Employers’ pay policies can contribute to the gender wage gap if women are less likely to work at high-paying firms or if women negotiate worse wage bargains then men. Analysing data from Portugal’s labour market, this research finds that differences among firms can explain up to 20% of the gender wage gap. Women tend to be employed at less productive firms that offer lower wages to their employees. Moreover, when women are hired by better-paying firms, their wages rise less than men, possibly because they are less effective negotiators. These findings call for renewed attention to equal pay and fair hiring laws.

Reducing the cost of living: how global retailers improve household welfare in Mexico

Big-box retail stores arriving from foreign countries have transformed the way Mexican households shop for goods, sparking a “supermarket revolution”. Traditionally, consumers in developing countries have shopped at street markets and small, independent stores. However, consumers have switched to shopping at foreign retailers, who offer a larger variety of products at cheaper prices. Despite concerns that foreign retailers might adversely affect local employment and household incomes, our evidence shows that allowing them to operate their businesses in Mexico has generated substantial welfare gains for households across the income spectrum by lowering the cost of living, while having limited impacts on total employment, incomes, and local businesses closing.

How much work can the long-term disabled do?

[intro]The number of people who receive long-term disability payments has grown rapidly in many countries, raising the question of whether it is possible for some of them to return to gainful employment. Analysing the impact of a major disability reform in the Netherlands, this research finds that long-term recipients of disability insurance were on average able to replace about 60% of lost benefits with labour income. This is evidence of substantial remaining work capacity among recipients and it suggests that there is scope for disability insurance reform to tap into this capacity.

The causes and consequences of US workers’ diverging locations by skill

The increase in spatial sorting of college and non-college workers into very different cities calls into question whether the large increases in wage inequality over the past three decades truly represents a similar increase in inequality in economic well-being. Since college graduates are paying much higher housing costs than lower skill workers, it is possible […]

Financial incentives and disability rates

Can financial incentives encourage disability program participants to work? Due to a lack of randomized experiments with well-defined treatment and control groups, there is little evidence on this question. This paper helps to fill the void by exploiting a policy change in the Norwegian disability system that approximates a well-controlled policy experiment. The results show that financial incentives induce many disability recipients to work, enough so that overall program costs fall in spite of the added financial incentives. The analysis points to the possibility that incorporating financial incentives into the U.S. disability system could achieve similar results.

Did welfare reform lead some American families to work less?

The landmark US welfare reform of 1996 provided strong incentives for poor women to work while receiving assistance – but it also provided incentives for some women to reduce their earnings to qualify for benefits. This research develops a new approach to detecting this ‘welfare opt-in’ effect and uses it to analyze data from a large randomized evaluation of welfare reform in Connecticut: the “Jobs First” program.
