Is the productivity effect of robotics technology another example of the modern productivity paradox? This study adds to the debate on this question by providing firm-level evidence from China and exploring the underlying mechanisms. Focusing on a recent period from 2013 to 2017, we find that...

This paper investigates the effect of robot adoption on employment adjustment at the firm level in China. Using an instrument that exploits the source of the firm-level variation in robot adoption, we find that using industrial robots increases employment within firms, especially when focusing...

Multiscale microstructure of tectonic coal evolution determines CBM storage, development and transport mechanism as well as its effect on coal and gas outburst potential. The multi-scale morphological and topological microstructure characterization of original and tectonic coals were performed...

Data envelopment analysis (DEA) has become a practicable approach to evaluate the relative efficiencies of decision-making units (DMUs) in various contexts. This paper conducted a DEA study to measure the relative efficiencies of 13 Credit Department of Farmers¡¦ Associations (CDFAs) of...

Constructed from high-frequency data, realized volatility (RV) provides an efficient estimate of the unobserved volatility of financial markets. This paper uses a Bayesian approach to investigate the evidence for structural breaks in reduced form time-series models of RV. We focus on the popular...

How to measure and model volatility is an important issue in finance. Recent research uses high frequency intraday data to construct ex post measures of daily volatility. This paper uses a Bayesian model averaging approach to forecast realized volatility. Candidate models include autoregressive...

We propose a new joint model of intraday returns and durations to study the dynamics of several Chinese stocks. We include IBM from the U.S. market for comparison purposes. Flexible innovation distributions are used for durations and returns, and the total variance of returns is decomposed into...
