Using the Panel Study of Income Dynamics, this paper studies household stock market participation and trading behavior in 2007–09, a period that saw a major stock market downswing. The stock market participation rate fell after the market crash. We find evidence that less-educated households,...

This article provides new evidence on household asset location decisions using the latest Survey of Consumer Finances (SCF). The authors find that the difference between the equity share in tax-deferred accounts (TDAs) and the equity share in taxable accounts (TAs), a measure of asset location...

We consider a class of nonsmooth convex optimization problems where the objective function is the composition of a strongly convex differentiable function with a linear mapping, regularized by the group reproducing kernel norm. This class of problems arise naturally from applications in group...

In many longitudinal studies, repeated measures are often correlated with observation times. Also, there may exist a dependent terminal event such as death that stops the follow-up. In this article, we propose a new joint model for the analysis of longitudinal data in the presence of both...

We investigate the effect of reaction-time delay of drivers upon traffic flow analytically and numerically. We extend the optimal velocity difference model by taking reaction-time delay of drivers into account. The stability condition is obtained. The Burgers, Korteweg–de Vries (KdV) and...
