绿色经济发展中政府介入时机与政策选择——基于技术采用均衡时间的比较静态分析

发展绿色经济推进经济转型是实现科学发展的核心。市场自身转型的滞后是影响绿色经济发展的重要因素。转型具有公共物品的性质,公共财政的本质意味着政府介入从而消除滞后的合意性。绿色新技术采用的滞后是造成转型滞后的关键,新技术采用路径的均衡时间受多种因素影响从而滞后的程度也就不同;但均衡时间的比较静态分析结果表明,新技术创新的强度、市场需求、贴现率、技术采用成本、既有生产成本以及企业行为等因素的改变都会影响均衡的采用时间,这些都为政府的介入提供了基础。     

风险投资对风险企业IPO功效研究——以我国深市中小板为例

Dual class shares – is India ready for it?

Market evidence suggest that a class of common stock with superior voting rights trades at systematically higher prices than an identical class of stock with inferior voting rights, as control over the firm grants the promoters some opportunity to receive a higher payoff. Differential voting rights class of shares may attract a certain class of investors who are only interested in the economic benefits of a company. It assists management in deterring potential rivals from winning a control and allows raising fresh capital for growth without giving up control. The value of controlling a firm derives from the fact that you believe that you or someone else would operate the firm differently from the way it is being run currently. Differential voting rights shares in different countries have indicated that voting rights are generally worth between 10% and 20% of the value of common stock. This article intends to create awareness about differential voting rights shares, to study the international as well as domestic experience and tries to examine the various factors that affect differential voting rights share prices.

Estimating liquidity premia in the Spanish government securities market

This paper investigates the presence of liquidity premia in the relative pricing of assets traded on the Spanish government securities market. First, a classification of bonds into four different categories based on their degree of liquidity is proposed. Second, liquidity premia are estimated introducing liquidity parameters in the estimation of the zero-coupon yield curve. Results suggest the existence of a liquidity premium for post-benchmark bonds (both strippable and non-strippable). The size of this premium is relatively small. In the case of pre-benchmark bonds, the lack of liquidity does not seem to be priced. It is also shown that these pricing discrepancies are robust to the impact of taxes on bonds.     

Recent evidence on the performance and riskiness of contrarian portfolios

The paper assesses the most recent performance, persistence and riskiness of contrarian portfolios. Evidence from the major world and European market of France shows that such portfolios appear profitable on average, but their performance is not persistent from one holding period to the next; hence there exist inherent risks, especially for investors that remain in markets for up to two consecutive investment periods. These risks, as measured by the CAPM (traditional, and less traditional versions that are meant to capture timing) and the Fama–French model, are not systematic and they are not related to market timing. Overall, taking only long positions in normal markets and hedged positions following market shocks seems to be the most promising route for contrarians in France.     

A mean/variance approach to long-term fixed-income portfolio allocation

Abstract

Long-term investments in bonds offer known returns, but with risks corresponding to defaults of the underwriters. The excess return for a risky bond is measured by the spread between the expected yield and the risk-free rate. Similarly, the risk can be expressed in the form of a default spread, measuring the difference between the yield when no default occurs and the expected yield. For zero-coupon bonds and for actual market data, the default spread is proportional to the probability of default per year. The analysis of market data shows that the yield spread scales as the square root of the default spread. This relation expresses the risk premium over the risk-free rate that the bond market offers, similarly to the risk premium for equities. With these measures for risk and return, an optimal bond allocation scheme can be built following a mean/variance utility function. Straightforward computations allow us to obtain the optimal portfolio, depending on a pre-set risk-aversion level. As for equities, the optimal portfolio is a linear combination of one risk-free bond and a risky portfolio. Using the scaling law for the default spread allows us to obtain simple expressions for the value, yield and risk of the optimal portfolio.     

Assessing Selectivity and Market Timing Performance of Mutual Funds for an Emerging Market: The Case of Turkey

This paper derives and analyzes the selectivity and market timing performance of the mutual funds for the Turkish economy for the financial crisis period by employing high-frequency data. The determinants of these derived abilities are investigated within a regression analysis. The results suggest weak evidence about selection ability and some evidence about superior market timing quality. They also indicate that management fees are negatively correlated with the ability measure, which is quite surprising. Experience emerges as an important factor, especially for market timing ability.     

An Empirical Analysis of the Volatility in the Open-End Fund Market: Evidence from China

This paper applies a set of GARCH models to investigate the three characteristics, including time persistence, leverage effect, and risk premium, of the volatilities of the four China Securities Index (CSI) fund indices. This study made the following four findings: (1) a strong ARCH effect exists in the returns; (2) time persistence is significant in all the CSI fund indices, namely, "stock index," "hybrid index," and "bond index" in descending order of significance; (3) the leverage effect is not statistically significant, yet there may be a positive leverage effect on the bond funds; (4) a risk premium effect exists in the open-end fund market, especially in the bond fund market.     

Growth to value: Option exercise and the cross section of equity returns

We propose a general equilibrium model to study the link between the cross section of expected returns and book-to-market characteristics. We model two primitive assets: value assets and growth assets that are options on assets in place. The cost of option exercise, which is endogenously determined in equilibrium, is highly procyclical and acts as a hedge against risks in assets in place. Consequently, growth options are less risky than value assets, and the model features a value premium. Our model incorporates long-run risks in aggregate consumption and replicates the empirical failure of the conditional capital asset pricing model (CAPM) prediction. The model also quantitatively accounts for the pattern in mean returns on book-to-market sorted portfolios, the magnitude of the CAPM-alphas, and other stylized features of the cross-sectional data.
