Until the 1970s, there was a consensus in applied macroeconometrics, both regarding the theoretical foundation and the empirical specification of macroeconometric modelling, commonly known as the Cowles Commission approach. This is no longer the case: the Cowles Commission approach broke down
in the 1970s, replaced by three prominent competing methods of empirical research: the LSE (London School of Economics) approach, the VAR approach, and the intertemporal optimization/Real Business Cycle approach. This book discusses and illustrates the empirical research strategy of these three
alternative approaches by interpreting them as different proposals to solve problems observed in the Cowles Commission approach.
