This paper proposes a pure-exchange economy with three key ingredients: habit formation, stochastic moments of aggregate consumption, and a small degree of heterogeneity in risk aversion consistent with empirical data. We obtain closed formulas for many equilibrium quantities, including the...

In models with recursive preferences, endogenous variation in Pareto weights would be interpreted as wedges from the perspective of a frictionless model with additive preferences. We describe the behavior of the (relative) Pareto weight in a two-country world and explore its interaction with...

This paper investigates the degree of risk sharing across households in China with heterogeneous risk and time preferences from the late 1990s to early 2010s. Standard tests assume homogeneous preferences across households, which may bias the true risk sharing degree if, in reality, preferences...
