Empirical growth regressions typically include mean years of schooling as a proxy for human capital. However, empirical research often finds that the sign and significance of schooling depends on the sample of observations or the specification of the model. We use a nonparametric local-linear...

The flow of foreign direct investment (FDI) has increased the challenges governments face in carrying out their fiscal responsibilities. A country’s system of law and order enables or constrains the implementation of government policies, and consequently influences whether the size of...

We extend a recently developed generalized local polynomial estimator into a semiparametric smooth coefficient framework to estimate a generalized cost function. The advantage of the generalized local polynomial approach is that we can simultaneously choose the degree of polynomial for each...
