This paper investigates the role of stochastic volatility and return jumps in reproducing the volatility dynamics and the
shape characteristics of the Korean Composite Stock Price Index (KOSPI) 200 returns distribution. Using efficient method of
moments and reprojection analysis, we find that stochastic volatility models, both with and without return jumps, capture
return dynamics surprisingly well. The stochastic volatility model without return jumps, however, cannot fully reproduce the
conditional kurtosis implied by the data. Return jumps successfully complement this gap. We also find that return jumps are
essential in capturing the volatility smirk effects observed in short-term options.

This paper proposes an extension of the minimal Hellinger martingale measure (MHM hereafter) concept to any order q≠1 and to the general semimartingale framework. This extension allows us to provide a unified formulation for many optimal martingale measures, including the minimal martingale measure of Föllmer and Schweizer (here q=2). Under some mild conditions of integrability and the absence of arbitrage, we show the existence of the MHM measure of order q and describe it explicitly in terms of pointwise equations in ? d . Applications to the maximization of expected power utility at stopping times are given. We prove that, for an agent to be indifferent with respect to the liquidation time of her assets (which is the market’s exit time, supposed to be a stopping time, not any general random time), she is forced to consider a habit formation utility function instead of the original utility, or equivalently she is forced to consider a time-separable preference with a stochastic discount factor. 相似文献

The literature has suggested that earnings and earnings forecasts provide stronger signals than dividends about future performance
of a firm. We test the information effects of simultaneous announcement of earnings and dividends in the Hong Kong market,
distinguished by three interesting features (concentrated family-shareholdings, low corporate transparency, and no tax on
dividends). Our results show significant share price reactions to unexpected earnings and dividend changes, but dividends
appear to play a dominant role over earnings in pricing, a result contrary to findings in the literature. The signaling hypothesis
works primarily for firms with earning increases, while the maturity hypothesis works mainly for firms with earnings declines.

The contextual nature of the predictive power of statistically-based quarterly earnings models 总被引:2,自引:2,他引:0
We present new empirical evidence on the contextual nature of the predictive power of five statistically-based quarterly earnings
expectation models evaluated on a holdout period spanning the twelve quarters from 2000–2002. In marked contrast to extant
time-series work, the random walk with drift (RWD) model provides significantly more accurate pooled, one-step-ahead quarterly
earnings predictions for a sample of high-technology firms (n = 202). In similar predictive comparisons, the Griffin-Watts (GW) ARIMA model provides significantly more accurate quarterly
earnings predictions for a sample of regulated firms (n = 218). Finally, the RWD and GW ARIMA models jointly dominate the other expectation models (i.e., seasonal random walk with
drift, the Brown-Rozeff (BR) and Foster (F) ARIMA models) for a default sample of firms (n = 796). We provide supplementary analyses that document the: (1) increased frequency of the number of loss quarters experienced
by our sample firms in the holdout period (2000–2002) vis-à-vis the identification period (1990–1999); (2) reduced levels
of earnings persistence for our sample firms relative to earnings persistence factors computed by Baginski et al. (2003) during earlier time periods (1970s–1980s); (3) relative impact on the predictive ability of the five expectation models
conditioned upon the extent of analyst coverage of sample firms (i.e., no coverage, moderate coverage, and extensive coverage);
and (4) sensitivity of predictive performance across subsets of regulated firms with the BR ARIMA model providing the most
accurate predictions for utilities (n = 87) while the RWD model is superior for financial institutions (n = 131).

Firm management typically claims that voluntary accounting method changes (VACs) are made to enhance the informativeness of
earnings by better matching accounting practices with economic reality. In contrast, skeptics argue that managers adopt new
accounting procedures to opportunistically manage earnings and influence their firm’s stock price. In this paper, we investigate
these alternative motives for VACs. Specifically, we investigate whether VACs cause equity prices to deviate from their fundamental
values in the short-term by studying the long-run stock-price performance for a sample of firms that voluntarily change accounting
methods. In addition, we investigate changes in earnings informativeness by examining the behavior of earning response coefficients
and the relationship between earnings and future cash flows in years surrounding the VAC event. In contrast to prior research,
we find little evidence that a strategy based solely on the earnings effect of a VAC can generate abnormal returns. While
we find weak evidence of post-VAC abnormal returns for extreme VACs, this result appears to be driven by the accruals anomaly
documented in Sloan [Sloan, R. G. (1996). The Accounting Review, 71, 289–315]. Our evidence further suggests that earnings informativeness is not significantly altered by voluntary changes
in accounting methods. Taken together, our evidence suggests the market recognizes the financial statement effects of alternative
acceptable accounting methods and efficiently processes the valuation implications of VACs.

Disclosure and the cost of equity in international cross-listing 总被引:1,自引:1,他引:0
Tim V. Eaton John R. Nofsinger Daniel G. Weaver 《Review of Quantitative Finance and Accounting》2007,29(1):1-24
In this paper, we examine the relationship between disclosure level and the cost of equity capital for a sample of international
firms cross-listing on the New York Stock Exchange. Increased disclosure has the potential to reduce information asymmetry,
reduce the cost of financing and increase analyst following. Using an international asset pricing model, we find that listing
firms experience a decrease in both disclosure risk and systematic risk while matching firms do not. Further, we find that
the magnitude of the decrease is related to three types of disclosure: accounting standards; analyst following; and exchange/regulatory
investor protection. Our results suggest that increased disclosure through accounting standards is beneficial to investors
and that disclosure can be accomplished through information intermediaries, e.g., analyst following. For firms with the lowest
levels of disclosure prior to cross-listing, all three types of disclosure appear to be valuable.

This paper identifies and corrects a typographical error in Black and Cox (J Finance 31:351–367, 1976). While the typographical error is seemingly trivial, the magnitude of the pricing error that it generates can be substantial.

This study examines how individual agents affect house selling prices and time on the market while controlling for brokerage
firm-specific effects as well as supply and demand conditions that vary by neighborhood. Firm size effects disappear once
firm specialization and agent characteristics are taken into account but geographic concentration by firms leads to higher
selling prices. For individual agents, neither sex nor selling own listings affects price or selling time, but there are gains
from partnering transactions across firms. Agents who specialize in listing properties obtain higher prices for their sellers
while those who specialize in selling obtain lower prices for their buyers. Houses nearer to other transactions of an agent
sell for higher prices. Finally, greater scale of listing and selling activity by an agent tends to lower selling price or
lengthen the time on the market.

U.S. banking regulators have proposed a bifurcated system of capital regulation where the largest, internationally active
banking organizations would be subject to significantly more risk sensitive regulatory capital requirements than are currently
in place, while most others would remain subject to the current rules. The proposed new capital regime has the potential to
affect the competitive landscape among banking institutions, particularly in the area of residential mortgage lending. We
analyze the potential competitive effects of the proposed, bifurcated regulatory capital system on competition in the residential
mortgage market from the perspective of the theory of regulatory capital arbitrage. We then apply the theory and available
evidence to perform some benchmark calculations that suggest a significant, potential shift of market share and income to
the largest banking institutions in the mortgage market.

Dynamic financial analysis (DFA) has become an important tool in analyzing the financial situation of insurance companies. Constant development and documentation of DFA tools has occurred during the last years. However, several questions concerning the implementation of DFA systems have not been answered in the DFA literature to date. One such important issue is the consideration of management strategies in the DFA context. The aim of this paper is to study the effects of different management strategies on a non-life insurer’s risk and return profile. Therefore, we extend the results of a recent working paper by Eling / Parnitzke / Schmeiser (2007) with two variants and test these variants numerically within a DFA simulation study. 相似文献
