A comment on the foundations of the precautionary demand for money

The model of the precautionary demand for money presented by Plessner and Reid (1980) is critically examined. It is shown that households derive no benefit from unscheduled consumption (in the model in question) and will therefore choose not to hold precautionary balances. Positive balances were obtained only by ensuring that scheduled consumption was chosen sub-optimally. However, this note confirms the Plessner-Reid hypothesis by explicitly modelling the benefits of unscheduled consumption.
