Abstract
Rival theoretical explanations of events and phenomena are common in economics, of which the Keynesian versus the monetarist debate is perhaps the best known. The traditional empirical procedure in economics has been to formulate a model from each theoretical framework and test each model's restrictions against observed data, rejecting or corroborating the specific model accordingly as the evidence is adverse or favourable. Although such an approach seems objective and scientific, it has two serious drawbacks: in practice neither rejection nor corroboration are definitive.
