The size-wage effect is well documented in the empirical literature, and typical attempts of explanation center on the supply side, using variations of the human capital approach, perhaps combined with institutional theories. With conclusive evidence of its source yet to emerge, an alternative...

There are few studies investigating the consequences of osteoporotic (low bone density) fractures in terms of costs and health outcomes. The purpose of this Swedish pilot study is to assess the costs and quality of life related to fractures of the hip, spine, wrist and shoulder and further to...

We consider an incomplete market in the form of a multidimensional Markovian factor model, driven by a general marked point process (representing discrete jump events) as well as by a standard multidimensional Wiener process. Within this framework we study arbitrage free good deal pricing bounds...

This paper presents a number of approaches to estimate returns to scale properties of general multiple-input muliple-output technologies. Both qualitative scale efficiency-properties and quantitative scale elasticity-properties are covered. The estimation approaches considered are based on data...

Empirical analyses for the US suggest that stronger people’s control over the school budget is deleterious to student performance. Using Swiss data on ninth graders in mathematics, reading and natural science collected jointly with the PISA study 2000, this paper tests this hypothesis for...

The paper investigates the redistributive effects of the Swedish health care financing system in 1980 and 1990 for four different financial sources: County council taxes, payroll taxes, direct payments oand state grants. The redistributive effects are decomposed into vertical, horizontal and...

The paper explores the question of whether markets under laissez-faire will be able to insulate an economy from bad government money. Some recent proposals favour freezing the monetary base, by abandoning central bank operations. This requires active participation by the monetary authorities,...

Casual observation suggests that people are more generous with their time than with their money. In this paper we present experimental evidence supporting the hypothesis. A third of our subjects demand no compensation for non-monetary investments, whereas almost all subjects demand compensation...

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...

In this paper, which is a substantial extension of the earlier essay Björk (2001), we give an overview of some recent work on the geometric properties of the evolution of the forward rate curve in an arbitrage free bond market. The main problems to be discussed are as follows. <p> 1. When is a...</p>
