Abstract:
A simple framework is constructed and extended to consider the theory of investment. It shows that there exists in industrialized economies a certain structure that determines the balance curve, which relates the rates of inflation and capital accumulation if demand and productive capacity are to be balanced as a whole at the initial stage of the next period. The balance curve, together with the modified short-period Phillips curve, governs the behavior of industrialized economies. In other words, they make it possible to recognize coherently the mechanism of chief economic phenomena such as growth, business cycles, creeping inflation and stagflation, and accordingly to prescribe for "diseases."
