The model also predicts that
—The growth rate will be high when the capital per worker is low and it will slow down as it gets higher.
—A low value of capital per worker also implies that MPK will be high meaning that real interest rate will be high.
—Real interest rate falls as capital’s marginal product declines as an economy develops.


索洛模型可以推导出以下结论：
1，当每工人的平均资本较低时，增长率高


这里的增长率是K(社会总资本）的增长率吧？另外，为什么当“每工人的平均资本较低时，增长率高”?
