This paper presents theoretical models and their empirical results for the return and variance dynamics of German stocks. A factor structure is used in order to allow for a parsimonious modeling of the first two moments of returns. Dynamic factor models with GARCH dynamics (GARCH(1,1)-M,...

In this paper we examine the difference between T-Bill returns and common stock returns in Turkey. We observe that there is a bond premium in Turkey unlike the equity premia in developed countries. As an attempt to explain this surprising observation, we incorporate inflation risk and default...

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...
