A new algorithm is developed to solve models with heterogeneous agents and aggregate uncertainty. Projection methods are the main building blocks of the algorithm and – in contrast to the most popular solution procedure – simulations only play a very minor role. The paper also develops a new...

This paper reconsiders the welfare benefit of unemployment insurance when individuals might self−insure through private savings but face aggregate fluctuations. We conclude that previous studies have under−estimated by half the average welfare gain from unemployment benefit by ignoring...

A new algorithm is developed to solve models with heterogeneous agents and aggregate uncertainty that avoids some disadvantages of the prevailing algorithm that strongly relies on simulation techniques and is easier to implement than existing algorithms. A key aspect of the algorithm is a new...
