I introduce an external habit for each consumption good, known as deep habits, into an otherwise standard international equilibrium model with multiple consumption goods and multiple countries. I show that deep habits coupled with consumption home bias account for a wide range of asset pricing...

We consider the welfare consequences of nudges to encourage exercise habit formation. We analyze a randomized trial of nudged exercise commitment contracts using a time-inconsistent intertemporal utility maximization model of the demand for exercise. Our empirical analysis shows that people who...

We study whether stocks are riskier or safer in the long run from the perspective of Bayesian investors who employ the long-run risk, habit formation, or prospect theory models to form prior beliefs about return dynamics. Economic theory delivers important guidance for long-run investment...

Following Part 1 of this article, which reviews late-1970s to 1990s classic derivations and tests of the consumption capital asset pricing model, here in Part 2 we review more recent developments, some of which are based on utility functions with non-time-separable preferences. Important...

This paper presents estimates for the consumption Euler equation for Russia. The estimation is based on micro-level panel data and accounts for the preference heterogeneity, measurement errors, and the impact of macroeconomic shocks. The presence of multiplicative habits is checked with the...

We consider the welfare consequences of nudges and other behavioral economic devices to encourage exercise habit formation. We analyze a randomized trial of nudged exercise commitment contracts in the context of a time-inconsistent intertemporal utility maximization model of the demand for...
