In this paper, the volatility of the return generating process of the market portfolio and the slope coefficient of the market model is assumed to follow a Markov switching process of order one. The results indicate very strong evidence of volatility switching behaviour in a sample of returns in...

In this short note we show how virtual arbitrage opportunities can be modelled and included in the standard derivative pricing without changing the general framework.

Bankruptcy brings the asset pricing implications of Lucas's (1978) endowment economy in line with the data. I introduce bankruptcy into a complete markets model with a continuum of ex ante identical agents who have CRRA utility. Shares in a Lucas tree serve as collateral. The model yields a...

Asset prices are forward looking. This evidence implies that prices of financial assets are essentially determined by the traders expectations about future prices. Another evidence about asset prices is that these do not seem to follow a predictable pattern over time; we observe periods of high...

The estimation of the discount rate for an investment project in conditions of risk relies upon two crucial assumptions: market completeness and well-diversified investors. Although, these two assumptions are tenable in developed capital markets, they are not suitable in emerging markets. In...

Using a newly developed dataset of daily, value-weighted market returns we construct and analyze the monthly realized volatility of the Athens Stock Exchange (A.S.E.) from 1985 to 2003. Our analysis focuses on the distributional and time series properties of the realized volatility series and on...

We generalize the Arbitrage Pricing Theory (APT) to include the contribution of virtual arbitrage opportunities. We model the arbitrage return by a stochastic process. The latter is incorporated in the APT framework to calculate the correction to the APT due to the virtual arbitrage...

We propose a theory based on investor overconfidence and biased self- attribution to explain several of the securities returns patterns that seem anomalous from the perspective of efficient markets with rational investors. The theory is based on two premises derived from evidence in...

This paper uses factor analytic techniques for deriving factor realizations from a group of main economic indicators of both the German and the Turkish economy in order to test the effect of economic factors on asset returns in an APT framework. The factor structure of the German economy yields...

This paper decomposes the overall market beta of common stocks into four parts reflecting uncertainty related to the long-run dynamics of stock- specific and market-wide cash flows and discount rates. We employ a discrete time version of Merton�s Intertemporal CAPM to test whether these four...
