The seminal study by Fama and MacBeth (1973) initiated a stream of papers testing for the cross-sectional relation between return and risk. The debate wether beta is a valid measure of risk has been renimated by Fama and French (1992) and subsequent studies.(...)

This paper develops a real options framework to analyze the behavior of stock returns in mergers and acquisitions. In this framework, the timing and terms of takeovers are endogenous and result from value-maximizing decisions. The implications of the model for abnormal announcement returns are...

Measuring and modeling financial volatility is the key to derivative pricing, asset allocation and risk management. The recent availability of high-frequency data allows for refined methods in this field. In particular, more precise measures for the daily or lower frequency volatility can be...

Wird vor Gericht über den Wert eines Unternehmens gestritten, so stehen fast immerdie Kapitalkosten im Vordergrund. Wie man diese für die Bewertung äußerst wichtigeGröße bestimmt, wird sowohl von Wissenschaftlern als auch von Praktikern diskutiert.Im Interesse des Dialogs zwischen beiden...

This study evaluated the relationship between inflation and infrastructure sector stock returns in emerging markets in the long and short run. It employed a panel autoregressive distributed lag (PARDL) model applying the mean group (MG), pooled mean group (PMG) and dynamic fixed effects (DFE)...

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...

This paper examines the time-varying behaviour of beta risk and degree of volatility persistence in the daily stock returns of 30 industry portfolios consisting of firms from the NYSE, AMEX and NASDAQ stock exchanges. Using an exponential ARCH (EGARCH) for this purpose, it further examines the...
