Unemployment, Growth and Distribution in a Goodwin-Kaldor Model -Dynamic Analysis of a Capitalist Economy-
构建古德温-卡尔多模型分析资本主义经济动态，发现投资波动导致经济内在不稳定，但足够强的财政政策可稳定经济，并给出内生持续增长周期的条件。
This paper develops a Goodwin-Kaldor model to examine the dynamic properties of a capitalist economy with the problem of effective demand. An important finding is that the economy is essentially unstable because of the volatility of investment spending. What is more, we investigate the macroeconomic activity of the government sector, which conducts stabilization policy through the use of fiscal instruments. In this case we show that the government can stabilize the unstable economy by adopting a sufficiently strong fiscal policy. In addition, we obtain an accurate condition for the emergence of endogenous and perpetual growth cycles by means of Hopf bifurcation theory.
