growth of all sectors and regions of an economy at the same proportional rate. This is unlikely ever to be observed in any actual economy, and it is hard to understand why it should ever have been thought to be desirable. It is true that if growth is so unbalanced that some sectors or regions of an economy actually decline, this may give rise to problems of adjustment. A very wide variety of patterns of growth is still possible, however, even if sharp declines are avoided. Most economies will find that at any given time, for various reasons of geography, technical change and market prospects, optimal growth involves some degree of imbalance between sectors and regions.
