This paper studies the relationship between three measures of relative earnings and firm performance based on data of 664 listed manufacturing companies in China over the period 2005-2012. It finds that (1) capital earnings relative to labor earnings and the overall average wage level relative to a firm’s average wage level had negative effects on firm performance; (2) the earnings of high-leve...
Three dimensions of the performance of firms in Ghana’s manufacturing sector are investigated in this paper: their technology and the importance of technical and allocative efficiency. We show that the diversity of factor choices in not due to a non-homothetic technology. Observable skills are not quantitatively important as determinants of productivity. Technical inefficiency is not lower in f...
This paper measures the productivity impact of shop-floor employee involvement. On the basis of a representative German establishment data set, the study finds that the introduction of team-work and autonomous work groups, and a reduction of hierarchies in 1996/97 significantly increased average establishment productivity in 1997 – 2000. The estimation strategy controls for unobserved invariant...
This paper investigates the relationship between telecommunications infrastructure competition, investment and productivity. Using econometric modelling and input-output economics, the analysis examines and measures the extent to which telecommunications has contributed to national and sectoral productivity performance. The main findings from this paper suggests that most industries have benefi...
Some multi-sector endogenous growth models make strong predictions about productivity differences across sectors in the form of a distribution or density function. In this paper it is demonstrated that this distribution is left-skewed for a wide range of plausible parameter values. This stands in strong contrast to the right-skewed shape of the respective empirical distribution estimated by ker...
Nonalcoholic fatty liver disease (NAFLD) can develop into end-stage disease that includes cryptogenic cirrhosis and hepatocellular carcinoma. Bacterial endotoxin, for example lipopolysaccharide (LPS), plays an important role in the pathogenesis of NAFLD. The aim of this study was to assess the role of LPS in the development of NAFLD. Twenty-one male Zucker (fa/fa) rats were divided into three g...
Sarcomas are a relatively rare cancer, but often incurable at the late metastatic stage. Oncolytic immunotherapy has gained attention over the past years, and a wide range of oncolytic viruses have been delivered via intratumoral injection with positive safety and promising efficacy data. Here, we report preclinical and clinical results from treatment of sarcoma with oncolytic adenovirus Ad5/3-...
We implement an endogeneous switching-regression model for labour productivity and firms’ decision to use business–to–business (B2B) e–commerce. Our approach allows B2B usage to affect any parameter of the labour productivity equation and to properly take account of strategic complementarities between the input factors and B2B usage. Empirical evidence from 1,394 German firms shows that firms u...
Using company account data for the US and four European countries this paper analyses the impact of ICT spillovers on companies’ performance. We use different definitions of spillovers to account for inter and intra-industry spillover effects, as well as assessing the presence of spillovers from the US to Europe. We also look at the possibility that spillovers might take some time to materialis...
This paper explores the issue of efficiency in English higher education using data envelopment analysis and stochastic frontier analysis to estimate an output distance function (which incorporates measures of both quantity and quality of teaching and research inputs and outputs) over a thirteen-year period. The study compares the efficiency estimates derived from various estimation methods, and...
