The success of such a market-based climate policy at minimizing overall abatement cost and fostering low-carbon investment and innovation depends on participants fully understanding the trade-offs between using, selling or banking a permit. This paper provides the first empirical evidence on how management quality moderates responses to carbon pricing, by focusing on firms that participated in two of Chinas regional pilot emissions trading schemes (ETS), located in the city of Beijing and Hubei province. We collect new data by interviewing plant managers or lead engineers at 216 randomly selected firms, and combine them with financial, patent and energy consumption data for each firm. First we find, as in similar studies for other countries, that well-managed firms have on average higher productivity. In addition, low-carbon innovation measures elicited from managers are strongly positively associated with green patenting. These results strengthen the credibility of our interview data. Second, we investigate whether carbon trading affects energy use of regulated firms. We estimate that the launch of the pilot ETS in Beijing has reduced consumption of coal and electricity by treated firms relative to control firms, but this effect is statistically significant only for well-managed firms. Our estimates imply that the overall reduction in coal use following the introduction of the pilot ETS would have been four times smaller if firms with above-median managers had been managed by below-median managers.

Speaker: Dr. HE Zilin is an associate professor in the Management Department at Tilburg University. His research interests include ambidextrous organization, behavioral theory of the firm, and innovation. He is also interested in research methods, especially U-shaped relationships and 3-way interactions. He has published in journals such as Organization Science, Strategic Management Journal, Research Policy, Journal of Economics and Management Strategy, Scientific Data, among others, receiving over 2500 citations in the Web of Science and over 6500 in Google Scholar. Venue: A623, Administration Building, Zijingang CampusAbstract:Without much loss of nuance, statistical significance asks this question: Is there an effect? Substantive significance is concerned with a more important question: How much of the effect is there?  Likewise, we sometimes want to know whether and to what extent we have a U-shaped relationship. To rephrase it, do I think about U and how much do I think about U? In this workshop, after a brief introduction to statistical vs. substantive significance and two general approaches to evaluate effect size, Dr. He will explain his ideas and procedures to assess the effect size or magnitude of a) a quadratic X-Y relationship, b) turning point shift, and c) flattening/steepening. Besides linear moderation of a quadratic X-Y relationship as the above, Dr. He will also explore with the workshop participants how to establish the magnitude of quadratic moderation of a linear X-Y relationship.

Speaker: HUANG Yiqi, Chinese University of HongkongVenue: Tencent meeting, meeting ID: 147-301-130Abstract:Consider sequences of C^2 Riemannian metrics which converge to a C^2 metric in C^0 sense. We show that if the scalar curvature of the sequence is almost non-negative in the integral sense, then the limiting metric has non-negative scalar curvature in the point-wise sense.
