  1. *Significant at 10%; **significant at 5%; ***significant at 1%. Coefficient standard errors are noted in parentheses.
  2. Regressions use an autoregressive-moving-average model with 2 lags and robust standard errors. We control for the month of the year in all regressions to account for seasonal correlations. Period 2004–2008 variable is a dummy variable that takes on a value of 1 for the years 2004–2008, and 0 otherwise.
