This book deals with international growth, featuring the dynamics of foreign debt and domestic capital. It proves useful to consider the Solow model, the overlapping generations model and the infinite horizon model. Phase diagrams serve to trace out the processes of adjustment induced by various shocks. Take for instance an increase in the saving rate, a rise in the rate of labour growth, or a one-time technical progress. What will be the effects on the balance of payments, the foreign position, the sk of capital, and consumption? The first chapter is concerned with the small open economy, chapter II is on large countries. In chapter III capital mobility is restricted, in chapter IV labour mobility is introduced, in chapter V wages are fixed, and in chapter VI growth becomes endogenous.
