Global Trends in Interest Rates
The trend in the world real interest rate for safe and liquid assets fluctuated close to 2 percent for more than a century, but has dropped significantly over the past three decades. This decline has been common among advanced economies, as trends in real interest rates across countries have converged over this period. It was driven by an increase in the convenience yield for safety and liquidity and by lower global economic growth.

The housing drag on core inflation
Some analysts have raised the question of whether the unprecedented declines in house values, which have been the hallmark of the recent recession, might be artificially dampening core inflation readings. However, a close examination of recent inflation data shows that the weakness in housing costs is representative of a broad pattern of subdued price increases across most consumption goods and services and is not distorting the broad downward trend in core inflation measures.

Has U.S. Monetary Policy Tracked the Efficient Interest Rate?
Interest rate decisions by central banks are universally discussed in terms of Taylor rules, which describe policy rates as responding to inflation and some measure of the output gap. We show that an alternative specification of the monetary policy reaction function, in which the interest rate tracks the evolution of a Wicksellian efficient rate of return as the primary indicator of real activity, fits the U.S. data better than otherwise identical Taylor rules. This surprising result holds for a wide variety of specifications of the other ingredients of the policy rule and of approaches to ...

CONDI: A Cost-Of-Nominal-Distortions Index
We construct a price index with weights on the prices of different PCE goods chosen to minimize the welfare costs of nominal distortions: a cost-of-nominal-distortions index (CONDI). We compute these weights in a multisector New Keynesian model with time-dependent price setting, calibrated using U.S. data on the dispersion of price stickiness and labor shares across sectors. We find that the CONDI weights mostly depend on price stickiness and are less affected by the dispersion in labor shares. Moreover, CONDI stabilization leads to negligible welfare losses compared to the optimal policy and ...

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 Mortgage Rate Conundrum
We document the emergence of a disconnect between mortgage and Treasury interest rates in the summer of 2003. Following the end of the Federal Reserve expansionary cycle in June 2003, mortgage rates failed to rise according to their historical relationship with Treasury yields, leading to significantly and persistently easier mortgage credit conditions. We uncover this phenomenon by analyzing a large dataset with millions of loan-level observations, which allows us to control for the impact of varying loan, borrower and geographic characteristics. These detailed data also reveal that ...

Investment shocks and business cycles
Shocks to the marginal efficiency of investment are the most important drivers of business cycle fluctuations in US output and hours. Moreover, these disturbances drive prices higher in expansions, like a textbook demand shock. We reach these conclusions by estimating a DSGE model with several shocks and frictions. We also find that neutral technology shocks are not negligible, but their share in the variance of output is only around 25 percent, and even lower for hours. Labor supply shocks explain a large fraction of the variation of hours at very low frequencies, but not over the business ...

Credit Supply and the Housing Boom
The housing boom that preceded the Great Recession was due to an increase in credit supply driven by looser lending constraints in the mortgage market. This view on the fundamental drivers of the boom is consistent with four empirical observations: the unprecedented rise in home prices and household debt, the stability of debt relative to house values, and the fall in mortgage rates. These facts are difficult to reconcile with the popular view that attributes the housing boom to looser borrowing constraints associated with lower collateral requirements. In fact, a slackening of collateral ...

The Effects of the Saving and Banking Glut on the U.S. Economy
We use a quantitative equilibrium model with houses, collateralized debt and foreign borrowing to study the impact of global imbalances on the U.S. economy in the 2000s. Our results suggest that the dynamics of foreign capital flows account for between one fourth and one third of the increase in U.S. house prices and household debt that preceded the financial crisis. The key to these findings is that the model generates the sustained low level of interest rates observed over that period.

Inequality, Risk, and Business Cycles
We quantify the connection between inequality, risk, and business cycles in a medium-scale New Keynesian model with tractable household heterogeneity, estimated with aggregate and cross-sectional data. We find that inequality and risk substantially amplify cyclical fluctuations. Most of this amplification operates through cyclical precautionary saving induced by countercyclical idiosyncratic risk. Savers reduce their consumption to insure themselves against large income drops, whose likelihood rises in recessions. Independent evidence supports both the magnitude and broad incidence of this ...
