We solve the optimal saving/portfolio-choice problem in an intertemporal recursive utility framework. Our solution to this problem is sufficiently general to allow (i) risk aversion to vary independently of intertemporal substitution, (ii) many risky assets, (iii) stochastic labor income that...

International capital flows have increased dramatically since the 1980s, with much of the increase being due to trade in equity and debt markets. Such developments are often attributed to the increased integration of world financial markets. We present a model that allows us to examine how...

This paper discusses calibration and numerical solution of a wide range of household portfolio models. We illustrate the main conceptual, technical, and computational issues that arise in the context of household portfolio choice, and explore the implications of alternative modeling choices. We...

This paper explores how the introduction of Rational Inattention (RI) affects optimal consumption and portfolio rules and asset pricing in the consumption-based CAPM framework. I first solve an otherwise standard portfolio choice and asset pricing model with RI explicitly and show that RI can...

We calibrate a life-cycle model with uninsurable labor income risk and borrowing constraints to match wealth accumulation and portfolio allocation profiles of direct and indirect stockholders in both taxable and tax-deferred accounts. Tax-deferred accounts generate an increase in wealth...

We show how applications in computational economics can take advantage of modern parallel architectures to reduce the computation time in a wide array of models that have been, to date, computationally intractable. The specific application comes from solving a portfolio choice model over the...

This paper solves numerically for the optimal consumption and portfolio choice of an infinitely lived investor facing short-sales and borrowing constraints, undiversifiable labor income risk and a predictable time varying equity premium. The investor aggressively times the market while positive...

This paper introduces the quest for status into the Ramsey model with endogenous labor supply. We focus our attention on relative wealth preferences. In contrast to relative consumption preferences, they allow for the possibility that agents work too little in the long run, while under both...

We investigate possible determinants of the increase of household debt and smaller consumption fluctuations since the 1980s in the US. We use a heterogeneous-agent model, in which labor income is risky and markets are incomplete. Consumers use durables not only as collateral for their debt but...
