We estimate the importance of teachers in Chicago public high schools using matched student-teacher administrative data. A one standard deviation, one semester improvement in math teacher quality raises student math scores by 0.13 grade equivalents or, over 1 year, roughly one-fifth of average yearly gains. Estimates are relatively stable over time, reasonably impervious to a variety of conditioning variables, and do not appear to be driven by classroom sorting or selective score reporting. Also, teacher quality is particularly important for lower-ability students. Finally, traditional human capital measures—including those determining compensation—explain little of the variation in estimated quality.

This paper tests a textbook consequence of competitive markets: that an industry-wide increase in the price of labor is passed on to consumers through an increase in prices. Using several data sources on restaurant prices, I explore the price impact of minimum-wage hikes in Canada and the United States. Particular attention is paid to the timing of these price responses to gauge the "stickiness" of minimum-wage cost shocks. I find that restaurant prices generally rise with changes in the wage bill and that this response is concentrated in the quarter surrounding the month during which the legislation is enacted.

This brief note adds to recent work that attempts to identify externalities associated with homeownership. The results suggest that some of the homeownership effect found in Green and White [5] is driven by family characteristics associated with homeownership, especially residential stability. However, as much as homeownership increases residential stability, it appears to be correlated with higher school attainment. Attempts to control for endogeneity cannot eliminate this finding.

This study uses a boundary design and propensity score methods to study the effects of the 1930s-era Home Owners Loan Corporation (HOLC) “redlining” maps on the long-run trajectories of urban neighborhoods. The maps led to reduced home ownership rates, house values, and rents and increased racial segregation in later decades. A comparison on either side of a city-level population cutoff that determined whether maps were drawn finds broadly similar conclusions. These results suggest the HOLC maps had meaningful and lasting effects on the development of urban neighborhoods through reduced credit access and subsequent disinvestment.
