Theorizing about public expenditure decision-making: (as) if wishes were horses ...

There have been several attempts to compare different approaches to modelling public expenditure decision-making. This paper is an extended comment on one such attempt: Fred Thompson and Richard Williams, A Horse Race Around a Möbius Strip: A Review and a Test of Utility Maximizing and Organizational-Process Models of Public Expenditure Decisions. In a commentary mode, we: (a) examine why tests of the sort that Thompson and Williams offer are neither definitive in choosing between models nor very useful in improving models; (b) outline a more meaningful test procedure; and (c) offer a somewhat more critical view than Thompson and Williams of the utility-maximizing approach to modelling public expenditure decisions.A comment on Fred Thompson and Richard Williams, A Horse Race Around a Möbius Strip: A Review and A Test of Utility-Maximizing and Organizational-Process Models of Public Expenditure Decisions, in this issue of Policy Sciences.
