We demonstrate that regression models can be estimated by working independently in a row-wise fashion. We document a … understanding the mechanics of many common regression models. These procedures can be used to speed up the computation of estimates … computed via OLS, IV, Ridge regression, LASSO, Elastic Net, and Non-linear models including probit and logit, with all common …

This paper addresses the steep learning curve in Machine Learning faced by noncomputer scientists, particularly social scientists, stemming from the absence of a primer on its fundamental principles. I adopt a pedagogical strategy inspired by the adage "once you understand OLS, you can work your...

We examine the impact of Articial Intelligence (AI) on productivity in the context of taxi drivers. The AI we study assists drivers with finding customers by suggesting routes along which the demand is predicted to be high. We find that AI improves drivers' productivity by shortening the...

The expansion of regionalism has spawned an extensive theoretical literature analysing the effects of Free Trade Agreements (FTAs) on trade flows. In this paper we focus on FTAs (also called European agreements) between the European Union (EU-15) and the Central and Eastern European countries...

This note argues that nonparametric regression not only relaxes functional form assumptions vis-a-vis parametric … regression, but that it also permits endogenous control variables. To control for selection bias or to make an exclusion … restriction in instrumental variables regression valid, additional control variables are often added to a regression. If any of …

We investigate the problem of optimal choice of the smoothing parameter (bandwidth) for the regression discontinuity … estimator. We focus on estimation by local linear regression, which was shown to be rate optimal (Porter, 2003). Investigation … selection ; local linear regression ; regression discontinuity designs …

Researchers are often interested in estimating the causal effect of some treatment on individual criminality. For example, two recent relatively prominent papers have attempted to estimate the respective direct effects of marriage and gang participation on individual criminal activity. One...
