We study social comparisons and status seeking in an interconnected society. Individuals take costly actions that have direct benefits and also confer social status. A new measure of interconnectedness—cohesion—captures the intensity of incentives for seeking status. Equilibria stratify players into social classes, with each class’s action pinned down by cohesion. A network decomposition algori...

This paper develops an informative column generation and decomposition method for a capacitated multi-item lot sizing and facility location problem with backlogging. The method hybridizes column generation to achieve a relaxed linear solution and a decomposition method (i.e., relax-and-fix) to achieve a feasible solution. The two solutions are used for a neighborhood search procedure that fixes...

We collect novel representative survey data examine separately whether interactions with inner outer social circles influence return perceptions, expectations, exposure widely known financial instrument in developed economy multiple information sources. find that respondent’s connectedness, proxied by perceived pr...

A holonomic function is a differentiable or generalized function which satisfies a holonomic system of linear partial or ordinary differential equations with polynomial coefficients. The main purpose of this paper is to present algorithms for computing a holonomic system for the definite integral of a holonomic function with parameters over a domain defined by polynomial inequalities. If the in...
