"Find a Job Now, Start Working Later: Does Unemployment Insurance Subsidize Leisure?"
Distorting incentives is a major concern when implementing Unemployment Insurance (UI).
In particular, UI benefits tend to decrease job search and increase the reservation wage. Yet,
UI could also be prone to moral hazard through another unexplored channel: postponing
job start upon finding a job. This paper develops a theoretical job search model that allows
for a delayed job start. Then, the extent to which unemployed individuals delay job start after
finding a job is assessed using the Canadian Survey of Labour and Income Dynamics. I find
that the benefits received while delaying job start accounts for 17% of all benefits paid. I find
that individuals who accepted an offer before benefit exhaustion delay job start by 3.9 weeks
on average, whereas the average delay is respectively 1.8 and 2.3 weeks for those who accepted
an offer after exhaustion and for non-recipients. The survival analysis confirms that the delay
between job offer and job start is longer when receiving UI benefits after accepting a job, and this
finding is robust to controlling for the time of job acceptance as well as personal and job
characteristics. It suggests that some individuals take advantage of the availability of UI benefits
to postpone job start.
Hunt, Jennifer, and Marjolaine Gauthier-Loiselle. 2010. "How Much Does Immigration Boost Innovation?"
American Economic Journal: Macroeconomics, 2(2): 31–56.
We measure the extent to which skilled immigrants increase innovation in the United States.
The 2003 National Survey of College Graduates shows that immigrants patent at double the
native rate, due to their disproportionately holding science and engineering degrees. Using
a 1940-2000 state panel, we show that a 1 percentage point increase in immigrant college
graduates' population share increases patents per capita by 9-18 percent. Our instrument for
the change in the skilled immigrant share is based on the 1940 distribution across states of
immigrants from various source regions and the subsequent national increase in skilled
immigration from these regions.
"Wage Effects of Parental Leave in Canada"
This paper estimates the incidence of extended maternity leave benefits on relative wages. I use
the 25 weeks increase in paid parental leave in Canada in 2000 to compute a differences-in-
differences estimator of the change in the relative average hourly wage of women of childbearing age.
Using the Survey of Labour and Income Dynamics (SLID), I compute estimates with and without
correction for sample selection and individual heterogeneity. In line with previous research, I find
no statistically significant effects in ordinary least squares specifications. However, using a method
that corrects for sample selection and unobserved heterogeneity, I find evidence that the extension of
parental leave benefits decreased the relative hourly wage of women of childbearing age by approximately
1% compare to older women. However, this decrease in the relative hourly wage doesn't translate into a
statistically significant effect on the relative annual earnings of women of childbearing age.
