Cross-Stock Comparisons of the Relative Contribution of Jumps to Total Price Variance
By Vivek Bhattacharya This paper uses high-frequency price data to study the relative contribution of jumps to the total volatility of an equity. In particular, it systematically compares the relative contribution of jumps across a panel of stocks from three different industries by computing the cross-correlation of this statistic for pairs of stocks. We identify […]
Relative Contribution of Common Jumps in Realized Correlation
By Kyu Won Choi This paper studies common intraday jumps and relative contribution of these common jumps in realized correlation between individual stocks and market index, using high-frequency price data. We find that the common jumps significantly contribute in realized correlation at different threshold cut-offs and both common jumps and realized correlation are relatively consistent […]
Volatility and Correlation Modeling for Sector Allocation in International Equity Markets
By Melanie Fan and Kate Yuan Reliable estimates of volatility and correlation are crucial in asset allocation and risk management. This paper investigates Static, RiskMetrics, and Dynamic Conditional Correlation (DCC) models for estimating volatility and correlation by testing them in an asset allocation context. Optimal allocation weights for one year found using estimates from each […]
Beta Estimation Using High Frequency Data
By Angela Ryu Using high frequency stock price data in estimating nancial measures often causes serious distortion. It is due to the existence of the market microstructure noise, the lag of the observed price to the underlying value due to market friction. The adverse eect of the noise can be avoided by choosing an appropriate […]
Time-Varying Beta: The Heterogeneous Autoregressive Beta Model
By Kunal Jain Conventional models of volatility estimation do not capture the persistence in high-frequency market data and are not able to limit the impact of market micro-structure noise present at very finely sampled intervals. In an attempt to incorporate these two elements, we use the beta-metric as a proxy for equity-specific volatility and use […]
Collusion with Three Bidders at First-Price Auctions
By Andrew Born Lopomo, Marx, & Sun (2009) show that, given a speci fied environment, pro table collusion is not possible for a two-person bidding ring operating at a fi rst-price sealed-bid auction. This research investigates the rigor of their result by expanding the theoretical framework to the case of a three-bidder cartel. The output generated from the […]
Strategic Behavior in Online Auctions: An Analysis of Sniping
by Claudia Lai Abstract Sniping is a prevalent phenomenon in eBay auctions, which have a fixed end time. Such practice seems apparently inconsistent with standard auction theory – last minute bids are received with reduced probability, and should rationally be submitted earlier – yet previous literature has shown that bidders typically do not engage in […]
Analysis of Auction Price Risk: An Empirical Study of the Australian Aboriginal Art Market
by Ilya Voytov Abstract Auction theory economists have shown that auctions can be structured to maximize the expected revenue to the seller. In this thesis, I show that they can also be optimized to minimize the sellers’ risk through an understanding of the driving factors behind seller’s auction price risk. I derive a general form […]
