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...

We propose a 2-country asset-pricing model where agents' preferences change endogenously as a function of the popularity of internationally traded goods. We determine the effect of the time-variation of preferences on equity markets, consumption and portfolio choices. When agents are more...

We develop a general equilibrium model of interest rates based on a continuous-time production economy populated by heterogeneous shareholders with logarithmic preferences. It allows us to study the impact of belief heterogeneity on bonds, the risk-free rate, and the yield curve. In particular,...

I study a parsimonious model of a time-varying market risk premium. State pricing is dominated by time preference shocks that may be independent of the consumption process. The model resolves several asset pricing puzzles and provides predictions for how the risk premium varies with measurable...

In this paper, I consider an exchange economy with complete markets where agents have heterogeneous beliefs and, possibly, preferences, and investigate the Market Selection Hypothesis that speculation rewards the agent with the most accurate beliefs. First, on the methodological level, I derive...

The construction of the original HML portfolio (Fama and French, 1993) includes six seemingly innocuous decisions that could easily have been replaced with alternatives that are just as reasonable. I propose such alternatives and construct HML portfolios. In sample, the average estimate of the...

The low beta anomaly is well documented for equity markets. However, the existence of such a factor in corporate bond markets is less explored. I find that European corporate bonds of firms with a low equity beta have higher risk-adjusted returns, on average, than European corporate bonds of...

We study a rational expectations' competitive equilibrium in a production economy, i.e., a system of prices at which firms' profit maximizing production decisions and individuals' preferred affordable consumption choices equate supply and demand in every market. We derive the equilibrium price...

We study the Epstein-Zin model with recursive utility. Recognizing that recursive preferences implies that the underlying model is not Markovian, we use methods not depending upon the Markov property to solve the model. We work with the returns directly, which we approximate by Taylor series...
