We evaluate the properties of mean reversion and mean aversion in asset prices and returns as commonly characterized in the finance literature. The study is undertaken within a class of well-known dynamic stochastic general equilibrium models and shows that the mean reversion/aversion...

In modern monetary economies, most payments are made with inside money provided by payment intermediaries. This paper studies interest rate dynamics when payment intermediaries value short bonds as collateral to back inside money. We estimate intermediary Euler equations that relate the short...

Academic finance has grown and evolved in the 46 years since the Journal of Financial Economics (JFE) began publishing papers. This paper uses detailed data on the 2,858 papers written by 3,152 different authors published in the JFE from 1974-2019. Cumulatively, these papers have received...

I review the literature on financial speculation driven by belief disagreements from a macro- economics perspective. To highlight unifying themes, I develop a stylized macroeconomic model that embeds several mechanisms. With short-selling constraints, speculation can generate over- valuation and...

We present a model to study the dynamics of risk premia during crises in asset markets where the marginal investor is a financial intermediary. Intermediaries face a constraint on raising equity capital. When the constraint binds, so that intermediaries' equity capital is scarce, risk premia...

Credit market imperfections provide the key to understanding many important issues in business cycles, growth and development, and international economics. Recent progress in these areas, however, has left in its wake a bewildering array of individual models with seemingly conflicting results....

After a survey of alternative theoretical approaches to modeling financial markets, the domestic and international financial linkages of major multicountry models are examined and assessed. The properties of these models are compared by calculating the slopes of their UI and BP curves for the...

"Intermediary asset pricing'' understands asset prices and risk premia through the lens of frictions in financial intermediation. Perhaps motivated by phenomena in the financial crisis, intermediary asset pricing has been one of the fastest growing areas of research in finance. This article...

We propose a theory of intermediation as rent extraction, and explore its implications for the extent of intermediation, welfare and policy. A frictional asset market is populated by agents who are heterogeneous with respect to their bargaining skills, as some can commit to take-it-or-leave-it...

We develop a dynamic equilibrium model of complex asset markets with endogenous entry and exit in which the investment technology of investors with more expertise is subject to less asset-specific risk. The joint equilibrium distribution of financial expertise and wealth then determines risk...
