“…Those are the backward induction procedure, referred to as BInduc throughout this paper, developed in Reiter (2009b), the parameterized distribution procedure, referred to as Param, of Algan et al (2009), and the explicit aggregation algorithm, referred to as Xpa, developed in den Haan and Rendahl (2009). These algorithms are summarized in the subsections on projection methods.…”

“…The algorithm iterates on this procedure until the information provided by the simulation is consistent with the assumptions made about the shape of the cross-sectional distribution. The philosophy that underlies our algorithm is similar to the one in Reiter (2009). The differences are mainly in terms of implementation, which is less cumbersome for our algorithm.…”
a b s t r a c tThis note describes how the incomplete markets model with aggregate uncertainty in Den Haan et al. [Comparison of solutions to the incomplete markets model with aggregate uncertainty. Journal of Economic Dynamics and Control, this issue] is solved using standard quadrature and projection methods. This is made possible by linking the aggregate state variables to a parameterized density that describes the cross-sectional distribution. A simulation procedure is used to find the best shape of the density within the class of approximating densities considered. This note compares several simulation procedures in which there is-as in the model-no cross-sectional sampling variation.
“…First, it illustrates the simplicity of our algorithm and brings to light the advantages relative to alternative algorithms. Second, we want to make clear why our algorithm can solve models with heterogeneous agents without generating a complete cross-sectional distribution by simulating a panel as is done by Krusell and Smith (1998) and without parameterizing the distribution as is done by Algan et al (2008Algan et al ( , 2009) and Reiter (2009).…”

“…The individual policy rules describe optimal behavior conditional on the aggregate laws of motions and the aggregate laws of motion provide a close fit for the behavior of the aggregates in a simulated panel that is generated using the individual policy rules. Algan et al (2008Algan et al ( , 2009) and Reiter (2009) parameterize the cross-sectional distribution, which is used to calculate next period's aggregate moments by numerically integrating over the individual choices. These algorithms have in common that (i) an additional function related to an aggregate variable, like a moment or the distribution, is separately parameterized and (ii) information about the crosssectional distribution-obtained by simulating a panel or by parameterizing the distribution-is used to establish a link between the individual and aggregate behavior.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
