Performance measures for evaluating the financial benefits of state term commodity

A common justification for state term commodity contracts is that they are beneficial to taxpayers because of savings that result from the price concessions expected from volume purchasing. With the growing popularity of performance based budgeting in state legislatures, there is a clear need for performance measures to document these taxpayer benefits. Based on a survey of state purchasing offices and a review of the major purchasing associations and the academic literature, this paper develops guidelines and a set of performance measures for evaluating the financial benefits of state term commodity contracts.
