Fig. 1.
Differences in log gun homicide rates between states that did versus did not change waiting periods due to the Brady Act, by year before or after Brady. Source: Figure generously provided by Luca et al. and from reestimating their main equation with log gun homicide rate as the dependent variable, but replacing the binary indicator for whether a waiting period is in effect with a series of indicator variables for whether the state–year observation is X years before or after adoption of a waiting period (X from −4 to +4, shown along the x axis). The figure plots the estimates and 95% confidence intervals for the coefficients on these indicator variables, so the y axis is percentage change divided by 100.
