Abstract: We performed a cross-sectional, "bottom-up" observational study of resource consumption and quality of life of patients with multiple sclerosis (MS) in the United Kingdom. Three centers participated in the study. Patients received a questionnaire either by mail or during a clinic...

Bernardo and Ledoit (2000) develop a very appealing framework to compute pricing bounds based on the so-called gain-loss ratio. Their method has many advantages and very interesting properties and so far one important drawback: the complexity of the numerical computation of the pricing bounds....

Walter Korpi argues in a previous issue of Challenge (March/April 2000) that Swedish economists’ claim that Sweden’s growth performance has been inferior to that of other industrialized countries is at odds with the facts. Since Sweden has not grown slowly relative to other countries, there...

In an internal capital market, individual departments may compete for a share of the firm´s budget by engaging in wasteful influence activities. We show that firms with more levels of hierarchy may experience lower influence costs than less hierarchical firms, even though the former provide...

Gender inequality in educational attainment remains a salient feature of contemporary Japanese society. This inequality lies not at the high school level but at the university level. Equal numbers of men and women advance to high school, but a significantly lower proportion of women advance to...

We investigate the term structure of forward and futures prices for models where the price processes are allowed to be driven by a general marked point process as well as by a multidimensional Wiener process. Within an infinite dimensional HJM-type model for futures and forwards we study the...

The purpose of this paper is to provide an explanation for relative pricing of futures contracts with respect to underlying stocks based on short sales constraints and informational lags between the two markets. In this model stocks and futures are perfect substitutes, except that short sales...

We consider interest rate models of Heath-Jarrow-Morton type where the forward rates are driven by a multidimensional Wiener process, and where the volatility structure is allowed to be a smooth functional of the present forward rate curve. <p> In a recent paper (to appear in "Mathematical Finance"...</p>

This paper shows that there exists a close relation between the net benefit and Fieller's methods for calculation of confidence intervals and performing hypothesis testing in cost-effectiveness analysis. The prices at which the net benefit confidence interval limits are equal to zero are...

The panel cointegration test of Larsson et al (1998) test for the maximum number of cointegrating relations in a dynamic panel given the assumption of a common cointegrating rank. This paper presents a test for this assumption. The test is based on the test statistic of Larsson et al (1998) and...
