Value

plot_bunching returns a plot with the frequency, counterfactual and bunching region demarcated. Can also include the bunching and elasticity estimate if specified.

Arguments

z_vector

a numeric vector of (unbinned) data.

binned_data

binned data with frequency and estimated counterfactual.

cf

the counterfactual to be plotted.

zstar

a numeric value for the the bunching point.

binwidth

a numeric value for the width of each bin.

bins_excl_l

number of bins to left of zstar to include in bunching region. Default is 0.

bins_excl_r

number of bins to right of zstar to include in bunching region. Default is 0.

p_title

plot's title. Default is empty.

p_xtitle

plot's x_axis label. Default is the name of z_vector.

p_ytitle

plot's y_axis label. Default is "Count".

p_miny

plot's minimum y_axis value. Default is 0.

p_maxy

plot's maximum y_axis value. Default is optimized internally.

p_ybreaks

a numeric vector of y-axis values at which to add horizontal line markers in plot. Default is optimized internally.

p_title_size

size of plot's title. Default is 11.

p_axis_title_size

size of plot's axes' title labels. Default is 10.

p_axis_val_size

size of plot's axes' numeric labels. Default is 8.5.

p_freq_color

plot's frequency line color. Default is "black".

p_cf_color

plot's counterfactual line color. Default is "maroon".

p_zstar_color

plot's bunching region marker lines color. Default is "red".

p_grid_major_y_color

plot's y-axis major grid line color. Default is "lightgrey".

p_freq_size

plot's frequency line thickness. Default is 0.5.

p_freq_msize

plot's frequency line marker size. Default is 1.

p_cf_size

plot's counterfactual line thickness. Default is 0.5.

p_zstar_size

plot's bunching region marker line thickness. Default is 0.5.

p_b

whether plot should also include the bunching estimate. Default is FALSE.

b

normalized bunching estimate.

b_sd

standard deviation of the normalized bunching estimate.

p_e

whether plot should also include the elasticity estimate. Only shown if p_b is TRUE. Default is FALSE.

e

elasticity estimate.

e_sd

standard deviation of the elasticity estimate.

p_b_e_xpos

plot's x-axis coordinate of bunching/elasticity estimate. Default is set internally.

p_b_e_ypos

plot's y-axis coordinate of bunching/elasticity estimate. Default is set internally.

p_b_e_size

size of plot's printed bunching/elasticity estimate. Default is 3.

t0

numeric value setting the marginal (average) tax rate below zstar in a kink (notch) setting.

t1

numeric value setting the marginal (average) tax rate above zstar in a kink (notch) setting.

notch

whether analysis is for a kink or notch. Default is FALSE (kink).

p_domregion_color

plot's dominated region marker line color in notch setting. Default is "blue".

p_domregion_ltype

line type for the vertical line type marking the dominated region (zD) in the plot for notch settings. Default is "longdash".
