We propose a set of new algorithms based on stochastic localization methods for large-scale discrete simulation optimization problems with convexity structure. All proposed algorithms, with the general idea of "localizing" potential good solutions to an adaptively shrinking subset, are...

Multivariate panel count data arise in event history studies on recurrent events if there exist several related events and study subjects can be examined or observed only at discrete time points instead of over continuous periods. In these situations, a complicated issue that may arise is that...

The two roles of a dealer in over-the-counter markets, immediacy provision and matchmaking, create a conflict of interest--the dealer prioritizes inventory turnover for immediacy provision, rather than making matches between customer flows. Compared to a counterfactual scenario without this...
