China is currently in a stage of high-quality economic development, but the high energy consumption and high pollution production methods of the construction industry are no longer adaptable to the country's economic development goals in the new era. As one of the important tools for the government to regulate high-quality advancement, taxation plays a vital role in the green development of the construction industry. This research uses panel data of 26 provinces in China from 2008 to 2017 and constructs a multiple intermediary effect model to conduct an empirical test on the impact of green taxes on the carbon emission efficiency of the construction industry and its mechanism. The results show that green taxation promotes carbon emission efficiency by accelerating the promotion of fixed capital investment in this industry, accelerating the flow of technological elements and technological research and development. This study further verifies that green taxation and carbon emission efficiency present an inverted U-shape relationship, and that the path mechanism of green taxation, fixed capital investment and technological progress-improving carbon emission efficiency of the construction industry has an intermediary effect. On this basis, suggestions are offered to rationally adjust the corporate tax burden, optimize the industrial structure, and actively guide the green transformation of the construction industry.

AbstractAlthough constrained by rules and regulations, informed short selling (tipping) is present before negative credit watch and certain types of rating downgrade announcements. Using entity credit rating and daily short sale data from April 2004 to December 2009, we find that preannouncement abnormal short selling significantly increases toward the announcement dates and is negatively related to postannouncement stock returns. Furthermore, short selling driven by tipping is more pronounced before more severe and more surprising rating downgrades. This study provides evidence favoring the private information hypothesis (tipping) in the ongoing debate of the informational advantage of short sellers.

This paper examines the informational role of trades in the corporate bond market. Using transaction data, we compare the temporal relation between volume and volatility of returns for both bonds and stocks issued by the same firms. We find a dramatic difference between these two securities. While there is a strong positive relation between return volatility and volume for stocks, this relation is much weaker for corporate bonds. This finding holds not only for straight bonds but also for callable and convertible bonds. Empirical evidence reveals a very different relation between volatility and volume in the corporate bond market than predicted by standard microstructure models. Results show that the role of volume and trade frequency can be quite different across asset classes.
