This paper concerns the distributional assumptions made on stock returns in the myopic loss aversion (MLA) proposed explanation to the equity premium puzzle. While Benartzi and Thaler (1995) assume temporal independence in these returns, we introduce a more realistic assumption incorporating...

The stock price is assumed to follow a jump-diffusion process which may exhibit time-varying volatilities. An econometric technique is then developed for this model and applied to high-frequency time series of stock prices that are subject to microstructure noises. Our method is based on first...

More and more firms tend nowadays to adopt environment-friendly attitudes. Their motivation originates in local environmental regulations or requirements of foreign markets to which firms export (both induced by consumers and investors' valuation of pro-environment initiatives). There is a...

Se estudió el comportamiento de los activos del mercado argentino en relación al mercado estadounidense (probablemente el más desarrollado del mundo en cuanto a legislación, volumen y liquidez). Se llega a la conclusión de que los retornos de los activos no se distribuyen normamente. Para...

We estimate the Dollar exposure of German DAX corporations. Our results are based on a new time-variant, APT-based and panel econometric extension of the exchange-rate exposure model in the tradition of Adler and Dumas (1984) and Jorion (1990). Our stock market data consist of 28 performance...

This article analyses value changes of German stock market companies in response to movements of the US dollar. The approach followed in this work extends the standard means of measuring exchange rate exposure in several ways (e.g. by using multi-factor modelling instead of augmented CAPM,...

Der vorliegende Beitrag quantifiziert anhand eines Marktmikrostruktur-Modells mit asymmetrischer Information den Einfluss der Anwender praktischer Entscheidungsregeln auf die Aktienkurse. Letztere werden als unvollständig informierte Anleger betrachtet. Neben diesen Anlegern agieren auf dem...

We estimate the impact of dollar changes on the value of German DAX corporations, using APT-modelling for the period 1977 - 1995. Several macroeconomic risk factors, including the dollar and a residual market factor representing the general market risk, are specified. The general notion is that...

In this paper, a model of bounded rational investors investing their portfolio in a passive investment vehicle (e.g., an Exchange Traded Fund replicating a broad index) or an actively managed fund is presented. The model proposes that the quick reswitching of these short-term oriented investors...

This paper considers simultaneous modelling of seasonality, slowly changing un- conditional variance and conditional heteroskedasticity in high-frequency fiancial returns. A new approach, called a seasonal SEMIGARCH model, is proposed to perform this by introducing multiplicative seasonal and...
