String theories with topologically complex compactification manifolds suggest the simultaneous presence of many unbroken U(1)’s without any light matter charged under them. The gauge bosons associated with these U(1)’s do not have direct observational consequences. However, in the presence of low energy supersymmetry the gauge fermions associated with these U(1)’s, the “photini”, mix with the B...
We give a memoryless scale-invariant randomized algorithm Mix-R for buffer management with bounded delay that is e/(e − 1)-competitive against an adaptive adversary, together with better performance guarantees for many restricted variants, including the s-bounded instances. In particular, Mix-R attains the optimum competitive ratio of 4/3 on 2-bounded instances. Both Mix-R and its analysis are ...
This paper presents new estimates of scale and product mix economies for U.S. commercial banks. We compare estimates derived from fitting a translog function to bank costs with estimates derived from nonparametric methods. We refine measures of scale and product mix economies introduced by Berger et al. (J. Monet. Econ. 20 (1987) 501) to accommodate nonparametric estimation, and estimate confid...
Firms use a rich set of incentives including fixed wages, bonuses, threat of firing and promise of promotion. Yet, we do not have a theoretical understanding of how such a mix of incentives can arise. This paper aims to build a theoretical model which describes the incentive mix as the solution to an optimal contracting problem and provides broader testable implications. The basic model has a p...
