Volume 4 in this research series contains nine papers. Following the tradition of the earlier volumes, it is similar in style to the first three volumes and illustrates ongoing research thrusts on a variety of financial economics issues that are germane to working capital management. The papers have been logically divided into three parts.The first part of the volume focuses on the issues covering short-term interest rates, short-term financial management, and a cash balance model. Part two contains papers that examine the issue of trade credit analysis under a competitive pricing situation and an environment in which the level of sales fluctuates. Finally Part 3 departs from the traditional discussions on working capital management in that it explores dividend payouts and tax environment changes as a source of concern to treasury (and financial) managers.This fourth volume presents a rich variety of papers that address an expanding facet of working capital management. It is hoped that the papers are found to be informative and act to stimulate research and practice in the area of treasury/financial management.
