“Realized Volatility Forecasting and Volatility Spillovers: Evidence from Chinese Non-Ferrous Metals Futures”

We study the prediction of realized volatility of non-ferrous metals futures traded on the Shanghai Futures Exchange from March 2011 to December 2017. A dynamic model averaging model is employed to combine multiple prediction models using time-varying weights based on individual model performance. Empirical results also reveal that models incorporating volatility spillovers across metals are important for forecast combinations, and short-term spillovers have a stronger impact than long-term spillovers. This approach offers the best forecasting performance and allows users to identify the most dominant model at any given time and demonstrate when and how volatility transmission from another metal is valuable for forecasting. We also find evidence of distinct trading behaviors in emerging and developed markets.

“Reconsidering Price Limit Effectiveness”

Most stock exchanges around the world impose daily price limits on stock prices. However, China is the only market that has experienced trading with and without price limits. We study China’s experience with price limits by comparing a subperiod with price limits to a subperiod without price limits. We provide three major sets of findings. First, we find price limits moderate transitory volatility and mitigates abnormal trading activity. Second, for poor performing stocks, a tighter price limit also appears helpful in moderating volatility and not hurtful. Finally, we find some evidence that price limits can facilitate market recovery following crashes. Many prior studies criticize price limits. Our study shows benefits of price limits.

“Redefining and Regulating the New Sharing Economy”

While proponents of regulating the sharing economy suggest a need to protect public health, workers, and incumbent businesses, to ensure localities are made whole for the use of public services, opponents of regulation argue that government intervention will stifle innovation and undermine economic and community benefits. The problem with both sides of this argument is that advocates and detractors alike often fail to address the wide differences among the practices and business entities that currently fall under the same umbrella. To address this inappropriate conflation and the resulting confusion among consumers and regulators alike, the goal of this article is to define the sharing economy as it now stands and to create a taxonomy that distinguishes and differentiates the various types of business entities that have been lumped into it. This article then proposes regulatory responses to the differing categories in the taxonomy based on the risks they present.

“Redefining Corporate Social Responsibility in an Era of Globalization and Regulatory Hardening”

Through our analysis of corporate trends, regulations, and case law from the United States, European Union, China, and India, we argue that the process of legalization and redefinition of CSR through a shareholder primacy lens may, troublingly, undermine the very notion of corporate social responsibility. In the face of these trends, this article redefines CSR with a reference to a fresh commitment to corporations’ social and ethical responsibility to society.
