In aggregation theory, the admissibility condition for clustering together components to be aggregated is blockwise weak separability, which also is the condition needed to separate out sectors of the economy. Although weak separability is thereby of central importance in aggregation and index...

This paper examines the great supply shock following the pandemic and the invasion of Ukraine, using a novel suite of supply indices. The suite has indices for the euro area total economy, euro area industries, sectors and countries. The suite also computes the contributions to the indices from...

This paper analyses the growth effects of high levels of human capital at the industry level. By favouring technology adoption, human-capital-intensive industries grow faster compared to less human-capital-intensive industries in economies that have higher levels of human capital. Using data for...

The aim of this paper is to examine whether the previously observed gap between growth of R&D and economic performance, known as the ‘Swedish paradox’, is a general phenomenon across all sectors of the economy, or only occurs in specific industry segments. The dataset used for the analysis...

We use a comprehensive database of Swedish manufacturing and service firms to examine trends in aggregate and sectoral research productivity 1985-1998, defined as the ratio between patenting and R&D. Quality indices are composed of forward and backward citations, family size and opposition. In...

Using data for 51 manufacturing and service sector for the period 1970-2005 in 14 countries, this paper show that employment protection legislation has a negative and significant effect on growth of value added and hours of work in more human capital intensive sectors. We argue that labour...

We estimate Okun's law, the negative relationship between output and the unemployment rate, at the sector level for the US, the UK, Japan, and Switzerland to test several hypotheses that may explain why the aggregate Okun's coeffcients are different across countries. Specifically, we show that...
