This study examines the evolution of econometric research in business cycle analysis during the 1960-90 period. It shows how the research was dominated by an assimilation of the tradition of NBER business cycle analysis by the Haavelmo-Cowles Commission approach, catalysed by time-series statisti… cal methods. Methodological consequences of the assimilation are critically evaluated in light of the meagre achievement of the research in predicting the current global recession.
