在增长率是外生的模型中，政府在决定增长方面没有任何作用。在我们的模型中，增长与投资相关，通过“边看边学”产生的外部性，而不是与资本存量水平相关。假设技术进步函数具有先增加后减少的收益，这会导致多个稳态增长均衡。在设定产出税率方面，政府政策也扮演着明确的角色。由此得出的结论是，尽管增长率的平稳分布是相同的，但结构相同、税收政策随机的两个经济体在持续时期内可能表现出非常不同的增长路径。考虑到补贴投资原则的可取性，考虑了各种实用的方法。版权所有：牛津大学出版社1992年。
Models in which the growth rate is exogenous provide no role for government in determining growth. In our model, growth is associated with investment, through externalities from "learning by watching," rather than with the level of the capital stock. Presumption of a technical progress function with first increasing and then decreasing returns leads to multiple steady-state growth equilibria. There is also an explicit role of government policy in setting tax rates on output. It follows that two economies with identical structures and stochastic tax policies may exhibit very different growth paths over sustained periods, although the stationary distribution of growth rates is the same. Given the desirability in principle of subsidizing investment, various practical methods are considered. Copyright 1992 by Oxford University Press.
