This study uses factor analysis to simplify the complex relationships among stock markets and to reduce the number of markets required for portfolio construction. Our sample consists of the US and 11 Asia-Pacific stock markets. We find that the reduced portfolio obtained from factor analysis has...

This research addresses an important problem in finance, which is the portfolio selection and management problem. Modern portfolio theory and Markowitz efficient frontier start with a set of assets (securities) and generate an optimal weight combination for the optimal risky portfolio that lies...

This paper addresses the problem of portfolio selection under a multifactor asset return model, using Bayesian analysis to deal with uncertainties in parameter estimation and model specification. These sources of error are ignored in the classical mean-variance method. We apply two approaches:...

In Anbetracht zunehmender Einkommensschwankungen aufgrund von Witterungsextremen und höherer Volatilitäten an den Agrarrohstoffmärkten fordert der Deutsche Bauernverband im Ertragsteuerrecht die Einführung einer Risikoausgleichsrücklage für landwirtschaftliche Einkünfte....

We compare the alternative approaches for regulating genetic information in the health insurance market when prevention measures are available. In the model, firms offer insurance contracts to consumers who are initially uninformed of their risk type but can obtain such information by performing...

Many public goods like dams, fire departments, and lighthouses do not provide direct utility but act more as insurance devices against floods, fire, and shipwreck. They either diminish the probability or the size of the loss. We extend the public good model with this insurance aspect and...

In this paper, we study the optimal self-insurance or insurance activities for a private forest owner against natural hazards. The specificities of natural risks, especially in forest, make indispensable to adjust the standard models of self-insurance and insurance. We develop such a model in...

This article presents the results of an experiment designed to test theoretical predictions about the impact of public compensation schemes and ambiguity on insurance and self-insurance decisions. Consistent with theory, we find that government assistance significantly reduces willingness to pay...
