Fig. A.1.

Event study of nationwide search intensity for learning resources. Notes: The figure above shows event study coefficients estimating the difference in the logarithm of nationwide weekly search intensity relative to the same weeks in prior years. The regressions are weighted by DMA population and include fixed effects for week of year (1–52), school year (2015–2020), and weeks containing major school holidays. Also shown are 95 percent confidence intervals calculated with heteroskedasticity robust standard errors. Panel A shows search intensity for school-centered resources and panel B for parent-centered resources. The sample contains search data from June 2015 through May 2020, excluding weeks with major school holidays.
