We show how the rootogram - a graphical tool associated with the work of J. W. Tukey and originally used for assessing goodness of fit of univariate distributions - can help to diagnose and treat issues such as overdispersion and/or excess zeros in regression models for count data. Two empirical...

The rootogram is a graphical tool associated with the work of J. W. Tukey that was originally used for assessing goodness of t of univariate distributions. Here we show that rootograms are also useful for diagnosing and treating issues such as overdispersion and/or excess zeros in regression...

Chinese employers practice extensive personal screening of job applicants. This study identifies four manifestations of this practice by motive – statistical, customer taste-based, employer taste-based, and regulatory – and evaluates their prevalence, economic determinants and implications...

This paper examines the impact of gravity on outsourcing. We derive a gravity equation from the classical spatial supply problem in which firms purchase some of their inputs from other firms paying the required transport costs. We also allow for different levels of productivity of the firms and...

Exploiting a large panel with an exhaustive coverage of cross-border acquisitions across more than 30 countries over more than a decade, this paper provides a comprehensive view of the eect of taxation on the desire of multinational enterprises to invest abroad. By considering the dierences...

Policies and interventions involving the built environment have become a promising opportunity for the promotion of walking as a sustainable transportation mode. Among voluminous literature, few studies were found that examined the association between the built environment and walking among the...

Count data regressions are an important tool for empirical analyses ranging from analyses of patent counts to measures of health and unemployment. Along with negative binomial, Poisson panel regressions are a preferred method of analysis because the Poisson conditional fixed effects maximum...
