Abstract The problem of misclassification is common in epidemiological and clinical research. In some cases, misclassification may be incurred when measuring both exposure and outcome variables. It is well known that validity of analytic results (e.g. point and confidence interval estimates for...

Drawing on a random-sampling of matched employer−employee data that was collected in 2016 by the People's Republic of China Employer−Employee Survey, we first estimate returns of education for Chinese manufacturing workers. Using hourly wages as the dependent variable, we find that the estimated...

We examine self-reported productivity of home workers during lockdown using survey data from the UK. On average, workers report being as productive as at the beginning of the year, before the pandemic. However, this average masks substantial differences across sectors, by working from home...

We examine reported productivity changes of workers over the course of the Covid-19 pandemic, which we validate against external metrics. On average, workers report being at least as productive as before the pandemic's onset. However, this average masks substantial heterogeneity, which is linked...

This paper offers a new economic explanation for the observed inter-industry differences in the size distribution of firms. The empirical estimates-based on three temporal (1982, 1987, and 1992) cross-sections of the four-digit United States manufacturing industries-indicate that increased...

The phenomenon of China's rise as an emerging scientific power has been well documented, yet the development of its social science is less explored. Utilizing up-to-date Social Science Citation Index (SSCI) publication data (1978-2013), this paper probes the patterns and dynamics of China's...

In an era of energy crisis, biomass-based bioenergy research has attracted the attention of R&D managers and policy makers around the world. This study explores the structural and dynamic patterns of biomass-based bioenergy research. We measure the profile of biomass research on both macro...

This paper offers a new economic explanation for the observed inter-industry differences in the size distribution of firms. The empirical estimates--based on three temporal (1982, 1987, and 1992) cross-sections of the four-digit United States manufacturing industries--indicate that increased...

This paper addresses the puzzle of how Chinese small and medium-sized enterprises (SMEs) in the mobile handset industry overcome an environment of “structured uncertainty” and innovate. We find that a combination of the global fragmentation of production and a tacit alliance between local...
