Using a framework akin to portfolio theory in asset pricing, we introduce the concept of “political beta” to model firm-level export diversification in response to global political risk. The main implication of our model is that a firm is less responsive to changes in political relations...

Fama's (1970) efficient market hypothesis (EMH) and the capital asset pricing model (CAPM) jointly ascribed to Markowitz (1952), Treynor (1961), Sharpe (1964), Lintner (1965) and Mossin (1966) remain the foundation of most finance and investment courses. This is surprising, given the sustained...

This paper uses the illiquidity measure of Amihud (2002) in forming illiquidity estimates for South Africa, Kenya, Morocco, Egypt and London. These are used within an augmented CAPM framework to form risk firm illiquidity premiums in addition to premiums attributable to firm size. The evidence...

This paper examines the evidence regarding predictability in the market risk premium using artificial neural networks (ANNs), namely the Elman Network (EN) and the Higher Order Neural network (HONN), univariate ARMA and exponential smoothing techniques, such as Single Exponential Smoothing (SES)...

The study adopts the instrumental variables (IV) and Shanken’s (1992) bias-adjusted estimator to mitigate the inherent errors-in-variables bias in Fama-MacBeth (FM, 1972) regression while allowing the use of individual stocks as test assets to avoid the shortcomings of using portfolios....

Der deutsche Aktienmarkt sah sich in den letzten 15 Jahren substantiellen Veränderungen gegenüber, welche unter anderem in eine zunehmende Internationalisierung und deutlich erhöhten Streubesitz mündeten. In der vorliegenden Arbeit untersuchen wir, inwieweit dies die aus klassischen...

This paper is an empirical investigation into the role of credit history in determining the spread on sovereign bank loans. It employs an error-in-variables approach used in rational-expectations-macro-econometrics to set up a structural model that links sovereign loan spreads to realized...

Asset pricing in its essence is a very controversial topic. Despite numerous research papers criticising traditional approaches, such as linear factor models, practitioners as well as academics repeatedly return to the milestone models such as the Capital Asset Pricing Model (CAPM), mainly due...

This study aims to investigate the market timing strategy in different market conditions (i.e. up, down, normal and in-financial-crisis situation) in the emerging market of Pakistan over the period 1995 to 2015. Furthermore, this study tests the validity of the capital asset pricing model (CAPM)...
