Can standard preferences explain the prices of out-of-the-money S&P 500 put options?
The 1987 stock market crash occurred with minimal impact on observable economic variables (e.g., consumption), yet dramatically and permanently changed the shape of the implied volatility curve for equity index options. Here, we propose a general equilibrium model that captures many salient features of the U.S. equity and options markets before, during, and after the crash. The representative agent is endowed with Epstein-Zin preferences and the aggregate dividend and consumption processes are driven by a persistent stochastic growth variable that can jump. In reaction to a market crash, the ...

Asymmetric Information, Dynamic Debt Issuance, and the Term Structure of Credit Spreads
We propose a tractable model of a firm?s dynamic debt and equity issuance policies in the presence of asymmetric information. Because ?investment-grade? firms can access debt markets, managers who observe a bad private signal can both conceal this information and shield shareholders from infusing capital into the firm by issuing new debt to service existing debt, thus avoiding default. The implication is that the ?asymmetric information channel? can generate jumps to default (from the creditors? perspective) only for those "high-yield" firms that have exhausted their ability to borrow. ...

On the Mechanics of Fiscal Inflations
The goal of this paper is twofold. First, we wish to better explain the relationship between Sargent and Wallace’s (1981) unpleasant monetarist arithmetic, the closely connected fiscal theory of the price level (FTPL), and the monetarist view of inflation. Second, we discuss how the recent inflationary episode has contributed to redistributing real resources from holders of government debt to the public purse. In particular, financial prices before the onset of the Covid pandemic suggest that investors viewed an inflationary shock such as the one we experienced as extremely unlikely, so the ...

Core and 'Crust': Consumer Prices and the Term Structure of Interest Rates
We propose a no-arbitrage model that jointly explains the dynamics of consumer prices as well as the nominal and real term structures of risk-free rates. In our framework, distinct core, food, and energy price series combine into a measure of total inflation to price nominal Treasuries. This approach captures different frequencies in inflation fluctuations: Shocks to core are more persistent and less volatile than shocks to food and, especially, energy (the 'crust'). We find that a common structure of latent factors determines and predicts the term structure of yields and inflation. The model ...

Conflict of interest and certification in the U.S. IPO market
We examine the long-run performance and valuation of IPOs underwritten by relationship banks. We find that over one- to three-year horizons these IPOs do not underperform similar stocks managed by independent institutions. Moreover, our analysis suggests that relationship banks avoid potential conflicts of interest by choosing to underwrite their best clients' IPOs. Consistent with this result, we show that investors value new issues managed by relationship banks higher than similar IPOs managed by outside banks. Our findings support the certification role of relationship banks and suggest ...

The Interplay Between Financial Conditions and Monetary Policy Shocks
We study the interplay between monetary policy and financial conditions shocks. Such shocks have a significant and similar impact on the real economy, though with different degrees of persistence. The systematic fed funds rate response to a financial shock contributes to bringing the economy back towards trend, but a zero lower bound on policy rates can prevent this from happening, with a significant cost in terms of output and investment. In a retrospective analysis of the U.S. economy over the past 20 years, we decompose the realization of economic variables into the contributions of ...

Human Capital and Long-Run Labor Income Risk
This review article examines the role of labor income risk in determining the value of a person?s human capital. We draw on the existing literature to present a model that incorporates various types of shocks to earnings. Within this framework, we highlight the implications of different assumptions about the correlation between market returns and labor income growth for the value of human capital and its riskiness. Further, the article surveys other work that applies similar ideas to assess the value and risk of pension promises. Finally, we discuss how to enrich the environment with ...

The Value and Risk of Human Capital
Human capital embodies the knowledge, skills, health and values that contribute to making people productive. These qualities, however, are hard to measure, and quantitative studies of human capital are typically based on the valuation of the lifetime income that a person generates in the labor market. This article surveys the theoretical and empirical literature that models a worker?s life-cycle earnings and identifies appropriate discount rates to translate those cash flows into a certainty equivalent of wealth. This paper begins with an overview of a stylized model of human capital ...

Why Does the Yield-Curve Slope Predict Recessions?
Why is an inverted yield-curve slope such a powerful predictor of future recessions? We show that a decomposition of the yield curve slope into its expectations and risk premia components helps disentangle the channels that connect fluctuations in Treasury rates and the future state of the economy. In particular, a change in the yield curve slope due to a monetary policy easing, measured by the current real-interest rate level and its expected path, is associated with an increase in the probability of a future recession within the next year. In contrast, a decrease in risk premia is ...
