Motivated by the recent reversal in labor productivity growth, this paper is analyzing the relationship between R&D expenditures and productivity. Time series data of the German manufacturing industry is used to estimate a variable cost function, with the stock of knowledge being modeled as a...

Efficiency measurement naturally requires the definition of a frontier as a benchmark indicating efficiency. Usually a measure reflecting the distance of a data point to the frontier indicates the level of efficiency. One of the crucial characteristics to distinguish efficiency measurement tools...

It is argued that the observed return rates on capital at firm-level have an upward bias if firms are producing with unobserved intangible capital. Using EUKLEED, a comprehensive firm level data base for Germany, this theoretical preposition is proved empirically. Furthermore, making unobserved...

It is standard in the literature on training to use wages as a sufficient statistic for productivity. This paper examines the effects of work-related training on direct measures of productivity. Using a new panel of British industries 1983-1996 and a variety of estimation techniques we find that...

Cobb Douglas production function parameters are not identified from cross-section variation when inputs are perfectly flexible and chosen optimally, and input prices are common to all firms. We consider the role of adjustment costs for inputs in identifying these parameters in this context. The...

This study measures productivity growth using the Metafrontier Malmquist-Luenberger productivity growth index (MML index) method and decomposes the index. The results are compared with those obtained from the conventional Malmquist-Luenberger (ML) productivity growth index. MML has two...

This paper analyzes the impact of load factor, facility and generator types on the productivity of Korean electric power plants. In order to capture important differences in the effect of load policy on power output, we use a semiparametric smooth coefficient (SPSC) model that allows us to model...

This paper examines the impact of floods on firms' capital accumulation, employment growth and productivity by using a difference-in-difference approach and considering firms' asset structure. We find evidence that companies in flooding regions show higher growth of total assets and employment...

The purpose of this paper is to develop a model that integrates inventory and labor decisions We extend a model of inventory behavior to include a detailed specification of the role of labor input in the production process and of the costs associated with it In particular we distinguish between...
