Family and partner interpersonal violence among American Indians/Alaska Natives

Family and partner interpersonal violence are common among American Indian/Alaska Native (AI/AN) populations. AI/AN women have the second highest prevalence of violence against women among all racial/ethnic groups in the United States, and child abuse prevalence rates in AI/AN populations are among the highest. Elder abuse in AI/AN is also an important concern, although data on this are sparse. This review describes the epidemiology of child abuse, violence against women, and elder abuse among AI/AN, including prevalence and associated risk factors. The authors discuss potential reasons for the high burden of interpersonal violence among AI/AN, including common risk factors. Important limitations in existing literature are also highlighted, along with recommendations for future research on this topic

Trading and investing in volatility products

Since the banking crisis the market for volatility exchange-traded products has developed rapidly as it opens to clients beyond the large institutional investor pool. Speculation is driven by increasingly complex leveraged and inverse exposures including those that attempt to trade on significant roll costs in volatility futures curves. Longer-term investors use these products for the purposes of equity diversification, driven by fears of an ongoing Eurozone crisis. We survey the burgeoning academic literature in this area and present a comprehensive and up-to-date comparison of the market and statistical characteristics of European and US exchange-traded volatility products

QE and the UK stock market: Does the Bank of England information dissemination strategy matter?

We use intraday aggregate stock market data and an event-study framework to assess the UK’s equity market reaction to the unexpected element of the Bank of England Monetary Policy Committee's asset purchase announcements for the 2009-2017 period. We assess the reactions of equity returns and their volatility over various time frames, both preceding and following the MPC announcements. Our results show that the UK unconventional monetary policy shocks have a significant impact on domestic equity returns and volatilities. The strength of this impact depends on the Bank’s information dissemination through inflation reports and the publication of the MPC's voting records

Interest Rate Volatility and Risk Management: Evidence from CBOE Treasury Options

This paper investigates US Treasury market volatility and develops new ways of dealing with the underlying interest rate volatility risk. We adopt an innovative approach which is based on a class of model-free interest rate volatility (VXI) indices we derive from options traded on the CBOE. The empirical analysis indicates substantial interest rate volatility risk for medium-term instruments which declines to the levels of the equity market only as the tenor increases to 30 years. We show that this risk appears to be priced in the market and has a significant time-varying relationship with equity volatility risk. US Treasury market volatility is appealing from an investment diversification perspective since the VXI indices are negatively correlated with the levels of interest rates and of equity market implied volatility indices, respectively. Although VXI indices are affected by macroeconomic and monetary news, they are only partially spanned by information contained in the yield curve. Motivated by our results on the magnitude and the nature of interest rate volatility risk and by the phenomenal recent growth of the equity volatility derivative market, we propose the use of our VXI indices as benchmarks for monitoring, securitizing, managing and trading interest rate volatility risk. As a first step in this direction, we describe a framework of one-factor equilibrium models for pricing VXI futures and options on the basis of empirically favored mean-reverting jump-diffusions

Equity trading volume and volatility: Latent information arrivals and common long-run dependencies

This article examines the behavior of equity trading volume and volatility for the individual firms composing the Standard and Poor's 100 composite index. Using multivariate spectral methods, we find that fractionally integrated processes best describe the long-run temporal dependencies in both series. Consistent with a stylized mixture-of-distributions hypothesis model in which the aggregate “news”-arrival process possesses long-memory characteristics, the long-run hyperbolic decay rates appear to be common across each volume-volatility pair. © 1999 Taylor & Francis Group, LLC
