This paper extends the research about the impact of an increase in background risk from cases with one decision variable to those with two decision variables. We apply the results of Eeckhoudt and Kimball (1992) to examine the comparative statics of an increase in background risk on demand for loss reduction that depends on market insurance and self-insurance together. We find that individuals ...

We prove that Bat her's odd-even (m;n)-merging networks are exa tly optimal for (m;n) = (3; 4k + 2) and (4; 4k + 2) for k 0 in terms of the number of omparators used. For other ases...

We are concerned with some conditions such as the trivial solution of a planar system of differential equations (including the Liénard system) that is globally attractive but not stable. We emphasize the connection with some nonoscillatory conditions. The results are related to the previous ones obtained by Hara in 1993. 2000 Mathematics Subject Classification. 34D45.

Let u; v be distin t verti es of a multigraph G with degrees d u and d v , respe tively. The number of edge-disjoint u; v-paths in G is bounded above by minfd u ; d v g. A multigraph G is optimally edgeonne ted if for all pairs of distin t verti es u and v this upper bound is a hieved. If G is a multigraph with degree sequen e D, then we say G is a realisation of D. We hara terize degree sequen...

Abstra t. A hara ter-based en oding method is presented for naturallanguage texts and geneti data. Exa t string mat hing from the en oded text is faster than from the original text, with medium and longer patterns. A ompression ratio of about 50% is a hieved as a by-produ t. The method en odes hara ters with variable-length odewords of 2-bit base symbols. An advan ed variant is ontext-dependent...

Kuriki and Fuji-Hara (1994) introduced an (r, 2)-design with mutually balanced nested subdesigns ((r, 2)-design with MBN), which is equivalent to a balanced array of strength 2 with s symbols, and gave some constructions of such (r, 2)-designs. In this paper, we consider cyclic orthogonal and balanced arrays, and we give a cyclic version of the results obtained by them. Furthermore, we give a c...

This paper examines the two-fund separation paradigm in the context of an infinite-horizon general equilibrium model with dynamically complete markets and heterogeneous consumers with timeand state-separable utility functions. With the exception of the dynamic structure, we maintain the assumptions of the classical static models that exhibit two-fund separation with a riskless security. Agents ...

INTRODUCTION Clinical trial data can be presented in ways that exaggerate treatment effectiveness. Physicians consider therapy more effective, and may be more likely to make inappropriate practice changes, when data are presented in relative terms such as relative risk reduction rather than in absolute terms such as absolute risk reduction and number needed to treat. Our purpose was to determin...

Physicians, patients and policy-makers are influenced not only by the results of studies but also by how authors present the results. Depending on which measures of effect authors choose, the impact of an intervention may appear very large or quite small, even though the underlying data are the same. In this article we present 3 measures of effect — relative risk reduction, absolute risk reduct...
