In a finite time horizon, incomplete market, continuous-time setting with dividends and investor incomes governed by arithmetic Brownian motions, we derive closed-form solutions for the equilibrium risk-free rate and stock price for an economy with a finite set of heterogeneous CARA investors...

We study implications of asymmetries in both preferences and fundamentals for put option demand across investors and the resulting market behavior. A heterogenous-agent model populated by investors with asymmetric preferences alongside standard risk-averse agents rationalizes the size and the...

Public corporations are brandishing their political identities. They are increasingly taking stands and messaging on highly charged social issues: gun control, gender and race, immigration, abortion, reproductive rights, and free speech. Corporate scholars have paid scant attention to this...

A central conjecture of behavioural finance is that arbitrage opportunities appear as a result of systematic irrational investment behaviour and persist since real-world arbitrage trades actually involve costs and risks due to market frictions and non-fundamental risk. This paper shows that the...

This study establishes the informational value of a firm’s product market competition, a measure derived from narrative disclosures in 10-K filings. Consistent with economic theory predicting faster mean reversion in earnings, we find that product market fluidity has large explanatory power...

Rational bubbles in stocks can cause increases in trading volume, even after accounting for their expansionary effect on output and consumption. Trading volume increases are not caused by speculation driven by differences in beliefs. Dividend-bearing assets used to transfer resources...

We consider a general equilibrium Lucas (1978) economy with one consumption good and two heterogeneous Epstein-Zin investors. The output is subject to rare large drops or, more generally, can have non-lognormal distribution with higher cumulants. The heterogeneity in preferences generates excess...

We study optimal portfolio choice and equilibrium asset prices induced by alpha-maxmin expected utility (alpha-MEU) models. In the standard Ellsberg framework we prove that alpha-MEU preferences are equivalent to either maxmin, maxmax or subjective expected utility (SEU). We show how ambiguity...

Not-too-tight (NTT) debt limits are endogenous restrictions on debt that prevent agents from defaulting and opting for a specified continuation utility, while allowing for maximal credit expansion. For an agent facing some fixed prices for the Arrow securities, we prove that discounted NTT debt...
