This book is essentially a report on a series of analyses of the determinants of growth, democracy, civil liberties, and inflation. As a statistical analysis with interpretation, it is excellent. If you want to know what factors really affect these variables, you will find answers here. However, the utility for modelers is limited, because the author inexplicably omits to report the extimated constant terms in any of his regressions. One hopes that succeeding publications will provide more help to those who are trying to construct dynamic models of economic growth.
