Notes: Estimates at selected percentiles are based on unconditional quantile regressions. Standard errors (not reported for brevity) are obtained using 500 bootstrap replications. Each estimate is obtained from a separate regression using model 3. Estimates for other variables (test states, test years, urban, local socio-economic background variables, and survey quarters) are not reported for brevity
Significance at the *10% level, **5% level, and ***1% level
