This paper introduces endogenous preference evolution into a Lucas-type economy and explores its consequences for investors' trading strategy and the dynamics of asset prices. In equilibrium, investors herd and hold the same portfolio of risky assets which is biased toward stocks of sectors that...

We develop a model that reproduces the return and volatility spread between sin and non-sin stocks, where investors trade off dividends with the ethical assessment of companies. We relax the assumption of boycott behaviour and investigate the role played by the dividend share of sin stocks on...

We develop a model that reproduces the average return and volatility spread between sin and non-sin stocks. Our investors do not necessarily boycott sin companies. Rather, they are open to invest in any company while trading off dividends against ethicalness. We show that when dividends and...

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...

This paper considers a general-equilibrium model with loss-aversion in consumption and heterogeneity: there is a continuum of agents, with s-shaped utility, who differ in the time-varying reference level of consumption. Heterogeneity in the reference level is crucial for the existence of the...

This paper analyzes the link between herd behavior and asset prices in a multi-good pure-exchange economy where investors' preferences evolve over time in response to the consumption decisions of other investors. More precisely, the rule of updating preferences incorporates a bandwagon effect,...

I propose a consumption-based asset pricing model that jointly explains the high equity premium, the counter-cyclical behaviour of stock returns, the upward sloping term structure of interest rates and the downward sloping term structure of equity. The driving forces behind these results are...

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 decompose total disagreement about macro variables into the disagreement among optimists (i.e., forecasters whose forecast exceeds a certain threshold) and pessimists. Optimistic (pessimistic) forecasters tend to disagree more in good (bad) times. Pessimistic (optimistic) disagreement...
