Abstract
The aim of the project is to study the effects of a program offering temporary employment to young people registered in schools in Uruguay. The program, called “Yo estudio y trabajo”, is unique because it allocates jobs through a lottery, which gives the opportunity to obtain for the first time robust estimates of the effects of working while studying. We plan to study effects on employment (formal and informal), earnings and education attainment combining both administrative and survey data. We will specifically focus on how young people manage to coordinate their work and study schedules, and on the effects of early work experience on the acquisition of non-cognitive skills.

Experiment Characteristics

Sample size: planned number of clusters
There are 5 yearly cohorts of participants (2012-2016). Each year, 600 individuals are traeted, around 20,000 are controls.
Sample size: planned number of observations
More than 100,000 individuals
Sample size (or number of clusters) by treatment arms
The administrative data will yield information on the universe of individuals going through the lottery (3,000 treated individuals and more than 100,000 controls). 1,200 individuals of the last cohort will be surveyed (600 treated and 600 controls).
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)

Abstract
Does working while in school smooth students' transition into the labor market? We provide evidence on this question by leveraging a one-year work-study program that randomized job offers among over 90,000 student applicants in Uruguay. Program rules forbade employers from employing participants in the same job after program completion, and less than 5 percent of participants ever worked in the same firm again. Two years after the program, participants had 8 percent higher earnings. Our results suggest that the program's focus on work-related skills was a key mechanism for earnings impacts
