Empirical Evidence: Bound-Parsons Debate<br />

Criticizes Parsons for using an endogenous variable on RHS<br />

Econometric problem: DIreprate = f (wage(−); law) with no variation<br />

in law<br />

Identification assumption: LFP rates equal across wage groups<br />

Potential solution: “control” for wage on RHS. Does not make sense.<br />

DI and obtains a similar elasticity<br />
