Low-probability insurance decisions : the role of concern
Schade, Christian D.; Kunreuther, Howard; Kaas, Klaus Peter - 2002
On the basis of a real high stakes insurance experiment with small probabilities of losses, we demonstrate that concern … is a more important driver of WTP for insurance than subjective probability estimates when there is ambiguity surrounding … probability insurance "puzzle" well known from the literature, where a part of individuals pays too much and a part nothing for …

Fractional cointegration and real exchange rates
Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2000
This paper uses fractional integration and cointegration in order to model the DM/dollar and the yen/dollar real exchange rates in terms of both monetary and real factors, more specifically real interest rate and labour productivity differentials. We find that whilst the individual series may be...

Multivariate volatility models
Fengler, Matthias R.; Herwartz, Helmut - 2001
Multivariate Volatility Models belong to the class of nonlinear models for financial data. Here we want to focus on multivariate GARCH models. These models assume that the variance of the innovation distribution follows a time dependent process conditional on information which is generated by...

Fractional integration and the dynamics of UK unemployment
Gil-Alaña, Luis A.; Henry, S. G. B. - 2000
This article is concerned with the dynamic behaviour of UK unemployment. However, instead of using traditional approaches based on I(0) stationary or I(1) (integrated and/or cointegrated) models, we use the fractional integration framework. In doing so, we allow for a more careful study of the...

A fractionally integrated model with a mean shift for the US and the UK real oil prices
Gil-Alaña, Luis A. - 2000
In this article we model the log of the U.S. and the U.K. real oil prices in terms of fractionally integrated processes with a mean shift. We use different versions of the tests of Robinson (1994), which have standard null and local limit distributions. The results indicate that if we model the...

A fractionally integrated exponential model for UK unemployment
Gil-Alaña, Luis A. - 2000
Fractionally integrated models with the disturbances following a Bloomfield (1973) exponential spectral model are proposed in this article for modelling the U.K. unemployment. This enables us a better understanding of the low-frequency dynamics affecting the series, without relying on any...

Fractional integration and business cycle features
Candelon, Bertrand; Gil-Alaña, Luis A. - 2001
We show in this article that fractionally integrated univariate models for GDP may lead to a better replication of business cycle characteristics. We firstly show that the business cycle features are clearly affected by the degree of integration as well as by the other short run components of...

Quantile hedging
Föllmer, Hans; Leukert, Peter - 1998
In a complete financial market every contingent claim can be hedged perfectly. In an incomplete market it is possible to stay on the safe side by superhedging. But such strategies may require a large amount of initial capital. Here we study the question what an investor can do who is unwilling...

On model based seasonal adjustment procedures
Breitung, Jörg - 1998
In this note the unobserved component approach underlying the software package SEATS is compared with the Beveridge-Nelson type of decomposition for seasonal time series. The main strength of the SEATS approach lies in the appealing model formulation and the careful specification and adjustment...
