This paper investigates how ownership changes affect the plant performance, focusing on the cotton spinning industry in early twentieth century Japan, where many plants experienced ownership changes. Through analyses of detailed plant-level data, it is revealed that, after ownership changes, plants tended to focus on low grade and low price products and, at the same time, total factor productiv...

This paper examines productivity growth in the Indonesian manufacturing sector. We use a longitudinal data set to calculate the effects on aggregate manufacturing productivity growth from improvements within establishments, from reallocation of market shares, and from the turnover of plants. The difference between domestic and foreign owned plants is examined together with a calculation of the ...

This paper examines the impact of floods on firms’ capital accumulation, employment growth and productivity by using a difference-indifference approach and considering firms’ asset structure. We find evidence that after a flooding companies in flooded regions show on average higher growth of total assets and employment than firms in areas not affected by flooding. The positive effect prevails f...

We study the effect of outdoor air pollution on the productivity of indoor workers at a pear-packing factory. Increases in fine particulate matter (PM2.5), a pollutant that readily penetrates indoors, leads to significant decreases in productivity, with effects arising at levels below air quality standards. In contrast, pollutants that do not travel indoors, such as ozone, have little, if any, ...

This paper considers an econometric approach to measuring substitutability of three types of energy, i.e. crude oil, electricity and diesel with capital and labour in the manufacturing sector of Greek industry during the period 1970]1990. A general dynamic framework is developed under the assumption that the structure of the production process is weakly separable in capital, labour and energy a...

In the standard framework of data envelopment analysis (DEA) models, the returns to scale are fully characterized using the multiplier on the convexity constraint of inefficient decision making units (DMU) using the projection of the input-output vector on the frontier. In this note, we investigate how the returns to scale measurements in DEA models are affected by the presence of regulatory co...

We analyse the impact of ICT spillovers on productivity using company data for the U.S. We account for interand intra-industry spillovers and assess the role played by firm’s absorptive capacity. Our results show that intra-industry ICT spillovers have a contemporaneous negative effect that turns positive 5 years after the initial investment. For inter-industry spillovers both contemporaneous a...

We document the evolution of productivity in a steel mini mill with fixed capital, producing an unchanged product with Leontief technology working 24/7. Despite—almost—unchanged production conditions, output doubled within the sample period (12 years). We decompose the gains into downtime reductions, more rounds of production per time, and more output per run. After attributing productivity gai...

For a stable supply of electricity power plants are required to provide ancillary services in addition to energy production. This paper suggests a solution for optimal bidding strategy for hydroelectric units operating in markets where both energy and ancillary services are priced simultaneously. The model is illustrated on a numerical example of a hydro unit operating in such markets of New Yo...

In this paper we present new measures for the bias in an import price index due to outsourcing. The m easure is developed fi rst for a high ly simplif ied case for the purpose of conveying the rationale for the measure. It is then generalized, yielding a m eaasure that could b e used in empirical stu dies. Before taking up this bias measurement problem , however, we expl ain the m easurement co...
