Originally published in 1971, this book uses the famous Tinbergen/Theil approach to the theory of economic policy, demonstrating the place of fiscal policy in a realistic policy context. The volume marries analytical developments in macroeconomics to the influence on the economy of the system of public finance. Attention is given to the problem co-ordinating fiscal policy with other policy instruments, notably monetary policy. A final chapter discusses the problems encountered in applying fiscal policy models to real situations.
