Our research aims to determine the effect of electricity distribution and energy consumption on industrial development dynamics that occur between regions in Indonesia by adding investment inflation as control variables. The analysis tools we use are static (Fixed Effect) dynamic (GMM) panel data model with a dataset 34 provinces for 2012-2019 period. results state has significant positive indu...

To what degree can labor reallocation mitigate the economic consequences of weather-driven agricultural productivity shocks? I estimate that temperature-driven reductions in demand for India are associated with increases nonagricultural employment. This suggests ability sectors to absorb workers may play a key role attenuating shocks. Exploiting firm-level variation propensity workers, relative...

Enterobacteriaceae share a common antigen (CA). This antigen exists as a powerful immunogen, when produced by Escherichia coli O14, and as a minimally effective immunogen, when present in cultures of most other smooth strains. The present study was directed toward the assessment of immunogenicity of this antigen produced by various rough mutants and their parent strains as well as that of viabl...

Using historical, ®rm-level data, this study compares the productivity of Japanese and U.S. integrated steel producers. In recent decades Japanese producers have demonstrated higher labor productivity than their U.S. counterparts, due largely to higher investment. Calculations of multifactor productivity suggest that the American ®rms, nevertheless, maintain a small advantage in overall ef®cien...

Underground coal mining is a dangerous industry where the regulatory state may impose tradeoffs between productivity and safety. We recover the marginal tradeoffs using disasters near a mine as shocks that increase future accident costs. We find that in the second year after a disaster, productivity decreases 11% and accident rates decrease 18-80% for mines in the same state, with some evidence...

We develop a multi-sector general equilibrium model in which productivity growth is driven by the production of sector-specific knowledge. In the model, we find that long run differences in total factor productivity growth across sectors are independent of the parameters of the knowledge production function except for one, which we term the fertility of knowledge. Differences in R&D intensity a...

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 micro evidence from manufacturing and services firms located in 55 African countries, this paper shows that better management practice, reflected by international management certification, helps firms to raise productivity. Larger and older firms and firms operating closer to the technological frontier are more likely to possess international management standards certification, as do firm...

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...
