January 2023 North America Newsletter
Today, we write with the news that Lawrence Katz is stepping down as co-scientific director of J-PAL North America after nearly ten years of leadership, having worked to launch the office in 2013. His wisdom has been invaluable in shaping the organization. We anticipate many future collaborations with Larry to advance rigorous research across key policy areas, such as workforce development, housing and homelessness, and education.
As we celebrate Larry and the past ten years of J-PAL North America, we are honored to provide key scientific direction to the next phase of the organization and to guide new projects and priorities, such as building career pathways for economic students from diverse backgrounds, expanding mentorship opportunities to junior researchers, scaling up programs found to be effective, and bolstering a research portfolio on important understudied topics such as racial equity.
We also want to take this time to thank you, our partners and supporters, for your continued commitment to the mission of improving lives through evidence. We look forward to future collaborations.

Dependence Duration and Labor Market Conditions
Researchers Matt Notowidigdo (University of Chicago), Kory Kroft (University of Toronto), and Fabian Lange (McGill University) assessed whether a longer period of unemployment negatively affected employment prospects by sending fictitious resumes to real job postings that randomly varied the length of an applicant’s unemployment spell. The results found that at eight months of unemployment, the likelihood of a callback for an interview was 45 percent lower than at one month of unemployment.
