Identifying permanent and transitory risks in the Chinese property insurance market

This paper develops a theoretical model to identify various risks in the Chinese property insurance market. Consequently, we apply a structural VAR model to quantify the magnitude, historical timing of these risks, and their dynamic impacts on the permanent and transitory components of the insurance premiums. The results indicate that the enormous amount of speculative funds flowing into China has aggravated insurance premiums as well as helped accelerate market volatilities due to its uncertain nature to the domestic economy and its short-term characteristic of investing. In particular, the speculative shock is shown to be the primary factor responsible for the transitory fluctuation of insurance premiums while the supply shock explains the preponderance of insurance premiums’ permanent growth in recent years.     

Alternative beta applied—an introduction to hedge fund replication

Motivated by the surge in popularity of passive hedge fund investments, the present article discusses the concept of “alternative beta” and its implications for the hedge fund industry. The article covers a variety of topics, ranging from the basic rationale for hedge fund replication to replication methodologies and products to the academic and financial market environment. We find that with their radical departure from the hedge fund hallmark of alpha delivery, passive replication products represent the next generation of hedge fund investing, and offer the catalyst for further development of the matured hedge fund industry. Further, we show how the alternative beta concept contributes to a proper separation of alpha, and thus enhances the overall efficiency and quality of hedge fund returns. The article also demonstrates that hedge fund replication can take several different forms. In conclusion, we believe that passive hedge fund products have the potential to consistently outperform mediocre (funds of) hedge funds on an after-fee basis.

THE INCENTIVES OF HEDGE FUND FEES AND HIGH‐WATER MARKS

Hedge fund managers receive a large fraction of their funds' profits, paid when funds exceed their high‐water marks. We study the incentives of such performance fees. A manager with long‐horizon, constant investment opportunities and relative risk aversion, chooses a constant Merton portfolio. However, the effective risk aversion shrinks toward one in proportion to performance fees. Risk shifting implications are ambiguous and depend on the manager's own risk aversion. Managers with equal investment opportunities but different performance fees and risk aversions may coexist in a competitive equilibrium. The resulting leverage increases with performance fees—a prediction that we confirm empirically.

基于波动率指数的期权对冲策略研究

波动率指数反映了期权投资者对未来市场波动性的预期,被用作衡量市场风险的重要依据。试图应用波动率指数来构建一种风险收益特性类似于债券的期权投资策略,即寻找市场中隐含波动率较相应的波动率指数高估或低估的期权品种并进行建仓,再用标的现货使组合保持delta中性。最后采用香港恒生指数期权数据进行了实证分析,结果显示该策略具有一定的实用价值,对期权投资具有一定的参考意义。     

A rational asset pricing model for premiums and discounts on closed‐end funds: The bubble theory

This paper provides a new explanation for closed‐end fund (CEF) discounts and premiums using the local martingale theory of asset price bubbles. This is a rational asset pricing model that is shown to be consistent with the existing empirical evidence on CEF discounts/premiums. Additional testable implications of the model are derived, which await subsequent research for their resolution. This bubble theory also applies equally well to understanding discounts and premiums on exchange traded funds.     

PROFIT SHARING IN HEDGE FUNDS

In a new scheme for hedge fund managerial compensation known as the first‐loss scheme, a fund manager uses her investment in the fund to cover any fund losses first; by contrast, in the traditional scheme currently used in most US funds, the manager does not cover investors' losses in the fund. We propose a framework based on cumulative prospect theory to compute and compare the trading strategies, fund risk, and managers' and investors' utilities in these two schemes analytically. The model is calibrated to the historical attrition rates of US hedge funds. We find that with reasonable parameter values, both fund managers' and investors' utilities can be improved and fund risk can be reduced simultaneously by replacing the traditional scheme (with 10% internal capital and 20% performance fee) with a first‐loss scheme (with 10% first‐loss capital and 30% performance fee). When the performance fee in the first‐loss scheme is 40% (a current market practice), however, such substitution renders investors worse off.     

The Changing Asymmetric Information Component of REIT Spreads: A Study of Anticipated Announcements

This study examines the risk-compensating behavior of REIT market makers. The bid-ask spread is hypothesized to compensate market makers for three costs: asymmetric information, order processing, and inventory. As the market makers perceived likelihood of transacting with a better-informed individual increases (decreases), the percentage of the spread that is attributed to asymmetric information will increase (decrease). This study examines the asymmetric information component of the bid-ask spread immediately prior to and following REIT dividend announcements and REIT funds from operations announcements during 1995 and 1996. The asymmetric information component increases the day before and then declines subsequent to dividend announcements of small and equity REITs. Asymmetric information costs increase following funds from operations announcements.
