Economists forecast economic growth, but always missed economic crisis. Policymakers talked about sustainable growth, but never knew what is required for “sustained growth.” Commentators discussed about economic crisis, but don’t seem to know the anatomy of economic crisis. People speak of economic shock, but no one seems to have any idea of how to measure the impact of the shock. This book fills these gaps. This book is intended for a wide audience. Policymakers will find this book useful for the analysis of economic growth, sustained growth, and the analysis of economic crisis. Economists will also find the new econometric models in this book useful. The critical mass function gives an alternative modeling approach to look at the requisite for sustained economic growth. The shock equation allows the prediction of the impact of the shock. Industry leaders contemplating to enter the ASEAN Economic Community (AEC) in 2015 will find this book to be a useful tool in determining the competitiveness of the AEC countries. University students studying economics will find this book to be a good introduction to econometrics.
