We consider a partially linear regression model with multivariate covariates and with responses that are allowed to be missing at random. This covers the usual settings with fully observed data and the nonparametric regression model as special cases. We first develop a test for additivity of the...

The paper investigates how entrepreneurial activity depends on economic development, measured by GDP per capita. The empirical analysis is based on GEM yearly data on 65 countries for the period from 2001 to 2011. We use nonparametric approach to show that variation in entrepreneurial activity...

This paper considers a linear triangular simultaneous equations model with conditional quantile restrictions. The paper adjusts for endogeneity by adopting a control function approach and presents a simple two-step estimator that exploits the partially linear structure of the model. The first...

In this paper, we attempt to determine whether the life-cycle income (LCI) hypothesis can explain movements in the national savings rate using the panel data of countries and the semi-nonparametric approach. While relating movements in the population density function to movements in the national...
