Estimation of Bunching in Distributions
bunch_count.ado calculates the degree of bunching at exogenously specified points in a distribution. This ado file was used to calculate the statistics in Chetty, Friedman, Olsen, and Pistaferri (2011) to quantify the degree of bunching in income at kink points in the tax system and to plot histograms in a computationally efficient manner. bunch_count.ado was written by Tore Olsen.
