A quantitative analysis of the u.s. housing and mortgage markets and the foreclosure crisis
We present a model of long-duration collateralized debt with risk of default. Applied to the housing market, it can match the homeownership rate, the average foreclosure rate, and the lower tail of the distribution of home-equity ratios across homeowners prior to the recent crisis. We stress the role of favorable tax treatment of housing in matching these facts. We then use the model to account for the foreclosure crisis in terms of three shocks: overbuilding, financial frictions, and foreclosure delays. The financial friction shock accounts for much of the decline in house prices, while the ...

Financial Stability Considerations for Monetary Policy: Theoretical Mechanisms
This paper reviews the theoretical literature at the intersection of macroeconomics and finance to draw lessons on the connection between vulnerabilities in the financial system and the macroeconomy, and on how monetary policy affects that connection. This literature finds that financial vulnerabilities are inherent to financial systems and tend to be procyclical. Moreover, financial vulnerabilities amplify the effects of adverse shocks to the economy, so that even a small shock to fundamentals or a small revision of beliefs can create a self-reinforcing feedback loop that impairs credit ...

The transmission of financial shocks and leverage of financial institutions: An endogenous regime switching framework
We conduct a novel empirical analysis of the role of leverage of financial institutions for the transmission of financial shocks to the macroeconomy. For that purpose we develop an endogenous regime-switching structural vector autoregressive model with time-varying transition probabilities that depend on the state of the economy. We propose new identification techniques for regime switching models. Recently developed theoretical models emphasize the role of bank balance sheets for the build-up of financial instabilities and the amplification of financial shocks. We build a market-based ...

Financial Stability Considerations for Monetary Policy: Empirical Evidence and Challenges
This paper reviews literature on the empirical relationship between vulnerabilities in the financial system and the macroeconomy, and how monetary policy affects that connection. Financial vulnerabilities build up over time, with both risk appetite and risk taking rising during economic expansions. To some extent, financial crises are predictable and have severe real economic consequences when they occur. Empirically it is difficult to link monetary policy to financial vulnerabilities, in part because financial cycles have long durations, making it difficult to separate effects of changes in ...

The Cost of Financial Frictions for Life Insurers
During the financial crisis, life insurers sold long-term policies at deep discounts relative to actuarial value. The average markup was as low as ?19 percent for annuities and ?57 percent for life insurance. This extraordinary pricing behavior was due to financial and product market frictions, interacting with statutory reserve regulation that allowed life insurers to record far less than a dollar of reserve per dollar of future insurance liability. We identify the shadow cost of capital through exogenous variation in required reserves across different types of policies. The shadow cost was ...

Levered Returns and Capital Structure Imbalances
We revisit the relation between equity returns and financial leverage through the lens of a dynamic trade-off model with costly capital structure rebalancing. The model predicts that expected equity returns depend on whether a firm's leverage is above or below its target leverage. We provide empirical evidence in support of the model predictions. Controlling for leverage, overlevered (underlevered) firms earn higher (lower) returns. A quantitative version of our model reproduces key facts about capital structure rebalancing and equity returns for U.S. corporations. Overall, our results ...

Revisiting Gertler-Gilchrist Evidence on the Behavior of Small and Large Firms
Gertler and Gilchrist (1994) provide evidence for the prevailing view that adverse shocks are propagated via credit constraints of small firms. We revisit the behavior of small versus large firms during the episodes of credit disruption and recessions in the sample extended to cover the 2007-09 economic crisis. We find that large firms'' short-term debt and sales contracted relatively more than those of small firms during the 2007-09 episode. Furthermore, the short-term debt of large firms also contracted relatively more in the previous tight money episodes if one takes into account the ...

Housing Wealth Effects: The Long View
We provide new time-varying estimates of the housing wealth effect back to the 1980s. We use three identification strategies: OLS with a rich set of controls, the Saiz housing supply elasticity instrument, and a new instrument that exploits systematic differences in city-level exposure to regional house price cycles. All three identification strategies indicate that housing wealth elasticities were if anything slightly smaller in the 2000s than in earlier time periods. This implies that the important role housing played in the boom and bust of the 2000s was due to larger price movements ...

Financial Stability and Optimal Interest-Rate Policy
We study optimal interest-rate policy in a New Keynesian model in which the economy can experience financial crises and the probability of a crisis depends on credit conditions. The optimal adjustment to interest rates in response to credit conditions is (very) small in the model calibrated to match the historical relationship between credit conditions, output, inflation, and likelihood of financial crises. Given the imprecise estimates of key parameters, we also study optimal policy under parameter uncertainty. We find that Bayesian and robust central banks will respond more aggressively to ...

Understanding Bank and Nonbank Credit Cycles: A Structural Exploration
We explore the structural drivers of bank and nonbank credit cycles using an estimated medium-scale macro model that allows for bank and nonbank financial intermediation. We posit economy-wide aggregate and sectoral disturbances to potentially drive bank and nonbank credit growth. We find that sectoral shocks affecting the balance sheets of entrepreneurs who borrow from the financial sector are important for the business cycle frequency fluctuations in bank and nonbank credit growth. Economy-wide entrepreneurial risk shocks gain predominance for explaining the longer-horizon comovement ...
