This study examines the relationships between stock fundamental ratios and idiosyncratic volatility from 1993 to 2010 for Australian Securities Exchange listed companies. The portfolio analysis results show that high idiosyncratic volatility companies tend to be small (measured by size), highly leveraged (measured by interest cover ratio), low profitability (measured by return on equity and ear...

Consider the Rational Expectations price history of an Arrow-Debreu security that matures in the money: p1; p2; :::; pT . Past information can be used to predict the return (pt+1 pt)=pt. Now consider a simple alternative performance measure: (pt+1 pt)=pt+1. It di ers from the return only in that the future price is used as basis. This variable cannot be forecasted from past information. The res...

This paper investigates the information content of the ex post overnight return for one-day-ahead equity Value-at-Risk (VaR) forecasting. To do so, we deploy a univariate VaR modeling approach that constructs the forecast at market open and, accordingly, exploits the available overnight close-to-open price variation. The benchmark is the bivariate VaR modeling approach proposed by Ahoniemi et a...

The basic model for valuation of firm is the Dividend Discount Model (DDM). When investors buy stocks, they expect to receive two types of cash flow: dividend in the period during which the stock is owned, and the expected sales price at the end of the period. In the extreme example, the investor keeps the stock until the company is liquidated; in such a case, the liquidating dividend becomes t...

Several authors have argued that because modern computing and communications technologies reduce buyer search costs and other market inefficiencies, there should be intense price competition between sellers in electronic markets. This paper examines this prediction using data on the airline ticket offerings of online travel agents (OTA). We find that different OTAs offer tickets with substantia...

This paper studies general-equilibrium e ects of government guarantees on assets in a stochastic growthmodel. It is shown that there is an inverted-U relationship between the guaranteed rate of return and price volatility. On the one hand, the initial e ect is that the capitalized value of government guarantees is larger in states with high prices that are likely to trigger bailouts, which tend...

In this paper, we investigate the multiscale cross-correlations between electricity price and trading volume in Czech market based on a newly developed algorithm, called Multifractal Cross-Correlation Analysis (MFCCA). The new algorithm is a natural multifractal generalization of the Detrended Cross-Correlation Analysis (DCCA), and is sensitive to cross-correlation structure and free from limit...

Previous research has examined whether price dispersion exists in theoretically highly efficient Internet markets. However, much of the previous work has been focused on industries with low cost and undifferentiated products. In this paper, we examine the presence of price dispersion and product differentiation using data on the airline ticket offerings of online travel agents (OTAs). We find t...

This study examines the role of pre-IPO discretionary accruals in the valuation and first day initial returns of IPOs. We find that IPO offer price is unaffected whereas market closing price is positively associated with the levels of pre-IPO discretionary accruals for issuers with aggressively reported earnings. We also find that this relative over-valuation of managed earnings by the markets ...

In order to characterize asset price and wealth dynamics arising from the interaction of heterogeneous agents with CRRA utility, a discrete time stationary model in terms of return and wealth proportions (among different types of agents) is established. When fundamentalists and chartists are the main heterogeneous agents in the model, it is found that in the presence of heterogeneous agents the...
