Few states and counties have a sense of the return on investment they are getting from their criminal and juvenile justice system expenditures. Money is spent and assumptions are made about outcomes, financial and substantive, without much notion of the real costs or benefits incurred. Yet this information is highly relevant to the decisions policymakers need to make, particularly in this fiscal climate. Within the past five years, cost-benefit analysis for justice policymaking and planning has become of more interest to state and local governments, with some jurisdictions taking steps to integrate CBA into decision making. This presentation will provide an overview and assessment of how governments are approaching the use of CBA in justice.
