This paper decomposes OECD convergence into contributions from sectoral productivity growth and contributions from employment shift across sectors. While productivity growth in services and agriculture contributed significantly to convergence, the contributions from employment shift and productivity growth in manufacturing are statistically insignificant.

Regional Economic Growth and Human Capital: The Role of Overeducation The paper analyses the link between human capital and regional economic growth in the European Union. Using various indicators of human capital calculated from census microdata, we conclude that the recent economic performance of European regions is associated with an increase in overeducation. In fact, measures of educationa...

When we allow capital depreciation to be endogenous, the acceleration of investment-specific technological progress can distort the measurement of the aggregate capital stock. Our quantitative exercise shows that this effect may cause a substantial bias in the measurement of total factor productivity and can account for a large portion of the observed productivity slowdown since the 1970s. 2006...

Using a new dataset on imports of technology and total factor productivity (TFP) over more than a century for the OECD countries, this paper tests for international technological transmission through trade. The empirical estimates suggest that imports of knowledge have been responsible for an almost 200% increase in TFP over the past century, but that the spillover effect has been highly uneven...

Abstract Introduction There is substantial evidence linking NF-κB and cancer-related processes. The aim of this study was to investigate the role IKKα, main catalytic component non-canonical pathway in colorectal cancer (CRC). Method Immunohistochemistry immunofluorescence used examine expression IKKα 1030 patients undergoing resection for stage I-III CRC. To assess inhibition, organoids were p...

Researchers of regional and international productivity comparisons are increasingly adopting various frontier approaches to examine convergence and the possible causes of productivity differences. We argue that economy-wide technology frontiers estimated with aggregate measures of output are downward biased. This bias extends not only to estimates of the technology frontier, but also produces i...
