We exploit a discontinuity in the New York Stock Exchange Designated Market Maker (DMM) contract to identify causal effects of DMM participation on equilibrium market outcomes. We document that contractual features that enhance DMM participation are associated with increased depth, narrower...

We examine the effects of secondary market liquidity on firm value and the decision to conduct an Initial Public Offering (IPO). Competitive liquidity provision can lead to market failure as the IPO either does not occur or the IPO price is discounted to reflect that some welfare-enhancing...

Price pressure induced by the short-seller's systematic unwinding and rewinding short positions around the weekend allegedly contributes to the weekend effect. On the Hong Kong Stock Exchange, short-selling was prohibited before 1994 and was allowed only for some stocks after 1994. Exploiting...

We examine the behavior of call options during the ex-dividend period of their underlying stocks. The evidence is inconsistent with the predictions of rational exercise policy; a significant fraction of the open interest remains unexercised. The potential profits to the option writers trigger a...

We survey empirical studies on the development and effects of increased computerization across equity, foreign exchange, derivatives, and fixed-income markets. While the changes in the trading process due to computerization in less liquid markets such as the corporate bond market have been...

Contest functions (alternatively, contest success functions) determine probabilities of winning and losing as a function of contestants’ eort. They are used widely in many areas of economics that employ contest games, from tournaments and rent-seeking to conflict and sports. We first examine...

We explore theoretical foundations and issues in the empirical estimation of conflict technologies. Such technologies are probabilistic choice functions that depend on the military capacities of adversaries, where the military capacities themselves depend on economic inputs via ordinary...

Voltage sag state estimation based on a limited number of accessible monitors is essential to assessing the cost balance between investments in mitigation device and disruption cost saved. In this paper, a deep learning method based on Bidirectional WaveNet for voltage sag state estimation via...

Much empirical research has been conducted concerning the effect of short-selling on market quality and volatility. However, the evidence is inconclusive and still a matter of debate. Using intraday data in a pure order-driven market we show that allowing for short-selling decreases the adverse...
