Previously developed methods to compute equilibria for stochastic overlapping generations economies where agents live a large number of periods will be applied to address several questions. Among them are the behavior of asset prices and the distribution of risks across agents in these type of economies. Another application is to investigate the implications of changes in the age structure of the population on intertemporal prices, and on the rate of capital accumulation. Finally, a quantitative assessment of the patterns of international borrowing and lending due to differences in the demographic structure of nations will allow an evaluation of the nature of the external deficit. The study will also develop a method suitable to quantitatively address heterogeneous, infinitely lived agents economies with capital, ideosyncratic and economy-wide shocks to productivity, and liquidity constraints. The development of this method will allow explicit consideration of many issues. Among them are: checking the robustness of the findings of real business cycle research to environments with pervasive liquidity constraints, and studying the behavior of different wealth and income groups during the business cycle, and the differential volatility of hours worked across skill groups. This project addresses many important issues regarding computable general equilibrium models that need to be better understood. The methods developed can be used to explore issues related to aging and savings, and the distribution of workers. This work will provide the crucial base upon which important policy issues can be addressed in the future.

先前开发的方法是针对代理人居住的随机重叠世代经济体计算平衡的方法，以解决几个问题。 其中包括资产价格的行为和这类经济体中代理商​​之间风险的分配。 另一个应用是研究人口年龄结构的变化对跨乘客价格的变化以及资本积累率的含义。 最后，由于国家人口结构的差异，对国际借贷和贷款模式的定量评估将允许评估外部赤字的性质。 该研究还将开发一种适用于定量解决非均质，无限寿命的经济体，具有资本，iDeosyncratic和经济范围内的经济体经济，以及生产力和流动性限制。 这种方法的开发将允许明确考虑许多问题。 其中包括：检查真实商业周期研究结果的鲁棒性，对具有普遍流动性限制的环境，并研究商业周期中不同财富和收入群体的行为，以及跨技能群体工作时间的不同小时波动。 该项目解决了需要更好地理解的可计算一般平衡模型的许多重要问题。 开发的方法可用于探索与衰老和储蓄以及工人分配有关的问题。 这项工作将为将来可以解决重要的政策问题提供至关重要的基础。
