(1) Graphically illustrate the difference between sharp RD and fuzzy RD (Note: the running variable is X. The treatment is only possible when X2 c. Y is outcome.) (7 points) X-c (2) Suppose we use local linear regression estimate the RD setting in part (1). Please graphically illustrate how the bandwidth parameter h affects the estimation result in the case of sharp RD (you only need to use two values of the parameter h).
