Our objective is to identify the trading strategy that would allow an investor to take advantage of excessive stock price volatility and sentiment fluctuations. We construct a general-equilibrium model of sentiment. In it, there are two classes of agents and stock prices are excessively volatile...

This paper studies the effects of heterogeneity in planning propensity on wealth inequality and asset prices. I consider an economy populated by attentive and inattentive agents. Attentive agents plan their consumption period by period, while inattentive agents plan every other period....

In a Lucas orchard with heterogeneous beliefs, we study the link between market-wide uncertainty, difference of opinionsand co-movement of stock returns. We show that this link plays an important role in explaining the dynamics of equilibriumvolatility and correlation risk premia. In our...

We study how the interaction of agents with different beliefs about a firm’s future cash flows determines the jointbehavior of credit spreads, option implied volatilities, and stock returns. Beliefs heterogeneity influences the pricing kernelin a way that supports more realistic credit spreads...

This paper studies the effects of heterogeneity in planning propensity on wealth inequality and asset prices. I consider an economy populated by "attentive" and "inattentive" agents. Attentive agents plan their consumption period by period, while inattentive agents plan every other period....

Many governments have tried to stabilize commodity prices based on the widespread belief that households in developing countries – especially poorer ones – value price stability, defined here as the lack of fluctuations around a mean price level. We derive a measure of multivariate price...

This paper shows that in asset pricing the information environment gives rise to a systematic risk factor when the informativeness of future news events varies with their content (i.e., bad news and good news are not equally informative). The paper further shows that in such cases (cross) serial...

Many commentators argue that uncertainty about tax, spending, monetary and regulatory policy slowed the recovery from the 2007-2009 recession. To investigate this we develop a new index of economic policy uncertainty (EPU), built on three components: the frequency of newspaper references to...

This paper estimates a bivariate HEAVY system including daily and intra-daily volatility equations and its macro-augmented asymmetric power extension. It focuses on economic factors that exacerbate stock market volatility and represent major threats to financial stability. In particular, it...

This paper investigates the time-varying dynamics of global stock volatility, commodity prices, and domestic output and consumer prices. The main empirical findings of this papers are: (i) stock volatility and commodity price shocks impact each other and the economy in a gradual and endogenous...
