The paper analyses the ability of a nonlinear asset pricing model suggested by Dittmar (2002) to explain the returns on international value and growth portfolios. For comparison we use some competing pricing models; such as the ICAPM, the exchange rate risk augmented ICAPM and the international...

If the preferences of the consumers are represented by utility functions that are differentiable, quasi-linear and satisfy the single-crossing condition, the characteristics of the profit maximizing nonlinear outlay schedule for a monopolist are well-known. We demonstrate that these...

The Black-Scholes formula is a well-known model for pricing and hedging derivative securities. It relies, however, on several highly questionable assumptions. This paper examines whether a neural network (MLP) can be used to find a call option pricing formula better corresponding to market...

We show in a theoretical model that the expected excess return on any asset depends on its covariance not only with the market portfolio, but also with changes in the representative agent’s estimate. In the empirical specification, this ”estimation factor” is based on realized growth in...

In this paper, we investigate the effects of cross-sectional disturbance correlation in a homogenous panel-data unit root test. As reported by other authors, the unit root test has incorrect size in the presence of cross-sectional correlation. We suggest that a previously known estimator can be...

Beliefs in signals that reveal lies or truths are widespread. These signals may lead to a truth or lie detection bias if the probability that such a signal is perceived by the receiver is contingent on the truth value of the sender’s message. Such detection biases are analyzed theoretically in...

This paper focuses on the many extreme credit default swap spread movements observed during the recent credit crisis and on how the tails of the spread (and price) change distribution significantly differ from those of the normal distribution even for diversified credit derivatives portfolios....

Vita brevis, ars longa (or: life is too short for abstracts)

This paper uses the choice experiment approach to assess people's preferences regarding road transports of hazardous materials. In a mail survey, carried out in Stockholm, the capital of Sweden, changes in exposure to hazardous materials are used as a proxy for changes in accident risk. The...

This paper studies efficiency in the provision of public education by local authorities using Data Envelopment Analysis (DEA). Viewing education as a multilevel production process the models control for differences at other levels. Most important is the students' socioeconomic backgound and a...
