Evaluating the Rationality of Fixed-Event Forecasts.
A Test of forecasts rationality based on the weak efficiency of fixed-event forecasts has recently been proposed by Nordhauss (1987). This paper considers the scope for pooling fixed-event forecasts across 'events' to deliver more powerful tests of the weak-efficiency hypothesis. In an empirial illustration we demonstrate the usefulness of this approach when only a small number of forecasts are available.
