Econometric techniques have turned macroeconomics into an empirical discipline. Yet, once the core concepts are examined, the empirical statements can neither invalidate nor select between the various theoretical proposals. Furthermore, the Dynamic Stochastic General Equilibrium method (DSGE) relies on a whole series of hypothesis that give precedence to theory. Empirical validation as a criterion for the evaluation both of the content of those models and of their progress is therefore excluded.Suite à l’essor de l’application des techniques économétriques, la macroéconomie est considérée comme une discipline empirique. Cette conjecture est discutable à l’examen de l’équation de Phillips, la règle de Taylor et la critique de Lucas. Les énon...
