Although investment is regarded as a key force of China’s economic growth, little study has been done to measure China’s investment efficiency. The present paper applies the data envelopment analysis (DEA) to Chinese provincial panel data from the year 2003 to 2008 for measuring the investment efficiencies and identifying their trends of Chinese 30 provinces and autonomous regions. A cross-effi...

This paper provides empirical evidence on the link between piracy and software protection, taking piracy determinants in cross–country regressions as basic reference. For that purpose, we use a panel data set for 24 countries over three years, 1994, 1997 and 2000, relating piracy rates to an index of software protection, per capita income and a set of country fixed effects. Results display that...

It has been argued that the most likely explanation for the result that earnings rise with firm size is that large firms employ high-ability individuals. In this paper we use matched employer-employee panel data from Ghana and Kenya and test for firm size effects in earnings regressions whilst controlling for unobserved ability in the form of worker fixed effects. For both countries we obtain a...

INTRODUCTION During the last few decades, healthcare expenditures (HCEs) have increased significantly in Iran and throughout the world. Understanding the determinants of such increases is essential to health policymakers in finding the best policies to manage healthcare costs. This study aimed to determine the impact of some of the key explanatory variables on household healthcare expenditures ...

PURPOSE Investigate the efficacy and pharmacodynamic effects of MK-1775, a potent Wee1 inhibitor, in both monotherapy and in combination with gemcitabine (GEM) using a panel of p53-deficient and p53 wild-type human pancreatic cancer xenografts. EXPERIMENTAL DESIGN Nine individual patient-derived pancreatic cancer xenografts (6 with p53-deficient and 3 with p53 wild-type status) from the PancX...

Two regression methods can be interpreted as based on Gini's mean difference (GMD). One relies on a weighted average of slopes defined between adjacent observations and the other is based on minimization of the GMD of the errors. The properties of the former approach are investigated in a multiple regression framework. These estimators have representations that resemble the OLS estimators, and ...
