bunching allows the user to conduct bunching analysis in
a kink or notch setting and returns a rich set of results. Important
features of the package include functionality to control for (different
levels of) round-number bunching or other bunching masses within the
estimation bandwidth, options to split bins by placing the bunching
point as the minimum, median or maximum in its bin (for robustness
analysis), and produces estimates of both parametric and reduced-form
versions of elasticities associated with the bunching mass. It also
returns (residual-based) bootstrapped vectors of estimates of all the
main estimable parameters (bunching mass, elasticity, marginal buncher,
dominated region, fraction in dominated region in notch setting, etc.)
which can be used for further analysis, e.g. incorporation into
structural models that rely on bunching moments. The package also
provides an exploratory viusalization function to speed up pre-analysis,
and produces plots in the Chetty et al. (2011) style
with lots of options on editing the plot appearance.
