An index of macroeconomic performance

This article develops a composite index of macroeconomic performance (IMP) and uses this index to ask: did the macroeconomic performance of the US economy improve during the 1990s relative to its own past performance; and has US macroeconomic performance been superior to that of other advanced capitalist economies during the post-war period as a whole? It is demonstrated that by studying the behaviour of an IMP, it is possible to draw conclusions about these comparative macroeconomic performance puzzles that are robust with respect to changes between multiple index weighting schemes.
