Managing inventory with proportional transaction costs

Semyon Malamud

We solve the problem of optimal inventory management for a CARA market-maker who faces proportional transaction costs and marking to market. Our model accommodates inventory shocks following an arbitrary compound Poisson process. We show that the no-tradin ...

Frictional Intermediation in Over-the-Counter Markets

Julien Hugonnier

We extend Duffie et al.'s (2005) search-theoretic model of over-the-counter (OTC) asset markets, allowing for a decentralized inter-dealer market with arbitrary heterogeneity in dealers' valuations (or, equivalently, inventory costs). We develop a solution ...

A test of inventory models with permissible delay in payment

Ralf Seifert, Olov Isaksson, Daniel Seifert

Contrary to the long-standing view in the finance literature that firms should maximise payment delays, research in operations management suggests that long payment delays can be suboptimal. In this study, we reconcile these two views by applying a seconda ...
