Downloadable! weakiv calculates weak-instrument-robust tests of the coefficients on the endogenous regressors in instrumental variables (IV) estimation of models with any number of endogenous regressors. In the probit model, the inverse standard normal distribution of the probability is modeled as a linear combination of the predictors. We exploit differences in the spatial distribution of industrial and liberal occupations in the years 1872 and 1920 to instrument for today's concentration of interpersonal and analytical skills in Brazil.

Fortunately, the authors of the popular xtabond2 and weakiv routines in Stata have recently added options that make it very easy to perform instrument strength diagnostics and generate weak instrument‐consistent confidence sets in the context of SYS‐GMM estimation.
