School Breaks and Crime: Quasi-Experimental Evidence from Sweden
摘要
We estimate the causal effect of school holidays on crime by exploiting the staggered timing of the Swedish winter sports break (sportlov) across municipalities.
Methods:We use a difference-in-differences design with municipality and year-by-week fixed effects on panel data covering 290 municipalities over 208 weeks (2021–2024). Poisson pseudo-maximum-likelihood (PPML) is the primary specification, with county-level cluster inference and Romano-Wolf step-down adjusted p-values for family-wise correction.
Results:The break reduces recorded assault by about 13 percent (PPML), concentrated among children of compulsory-school age (7–14:
The school environment concentrates youth in ways that produce interpersonal-conflict opportunities; the break disperses that concentration for one week and assault drops. Aggregate effects on total and property crime are suggestive but sensitive to specification.
