Models and methods for economic policy; 60 years of evolution at CPB

The Netherlands Bureau for Economic Policy Analysis (CPB) has been involved in econometric model building since its foundation in 1945. During the 60 years of model building and use reviewed in this Discussion Paper, CPB's models have evolved significantly. Over this period, a shift of emphasis can be observed from econometrics and empiricism to economic theory. New questions from policymakers and new features in the national economy have guided research, while new developments in econometrics and economic theory were taken on board wherever they helped to improve the quality and scope of the analysis. Although considerable progress has been achieved in several spheres, the models continue to be riddled with some long-standing limitations and weaknesses which the model users should take into account.
