Estimation of production functions by the Olley-Pakes, Levinsohn-Petrin and Wooldridge methodologies. The package aims to reproduce the results obtained with the Stata's user written opreg and levpet commands. The first was originally proposed by Olley, G.S. and Pakes, A. (1996) doi:10.2307/2171831. The second by Levinsohn, J. and Petrin, A. (2003) doi:10.1111/1467-937X.00246. And the third by Wooldridge (2009) doi:10.1016/j.econlet.2009.04.026.
