Working Paper
Macrofinancial History and the New Business Cycle Facts
In advanced economies, a century-long near-stable ratio of credit to GDP gave way to rapid financialization and surging leverage in the last forty years. This ?financial hockey stick? coincides with shifts in foundational macroeconomic relationships beyond the widely-noted return of macroeconomic fragility and crisis risk. Leverage is correlated with central business cycle moments, which we can document thanks to a decade-long international and historical data collection effort. More financialized economies exhibit somewhat less real volatility, but also lower growth, more tail risk, as well ...

The Time for Austerity: Estimating the Average Treatment Effect of Fiscal Policy
Elevated government debt levels in advanced economies have risen rapidly as sovereigns absorbed private sector losses and cyclical deficits blew up in the Global Financial Crisis and subsequent slump. A rush to fiscal austerity followed but its justifications and impacts have been heavily debated. Research on the effects of austerity on macroeconomic aggregates remains unsettled, mired by the difficulty of identifying multipliers from observational data. This paper reconciles seemingly disparate estimates of multipliers within a unified framework. We do this by first evaluating the validity ...

Mortgaging the future?
In the six decades following World War II, bank lending measured as a ratio to GDP has quadrupled in advanced economies. To a great extent, this unprecedented expansion of credit was driven by a dramatic growth in mortgage loans. Lending backed by real estate has allowed households to leverage up and has changed the traditional business of banking in fundamental ways. This ?Great Mortgaging? has had a profound influence on the dynamics of business cycles.

Private credit and public debt in financial crises
Recovery from a recession triggered by a financial crisis is greatly influenced by the government?s fiscal position. A financial crisis puts considerable stress on the government?s budget, sometimes triggering attacks on public debt. Historical analysis shows that a private credit boom raises the odds of a financial crisis. Entering such a crisis with a swollen public debt may limit the government?s ability to respond and can result in a considerably slower recovery.

Sovereigns versus Banks: Credit, Crises, and Consequences
Two separate narratives have emerged in the wake of the Global Financial Crisis. One speaks of private financial excess and the key role of the banking system in leveraging and deleveraging the economy. The other emphasizes the public sector balance sheet over the private and worries about the risks of lax fiscal policies. However, the two may interact in important and understudied ways. This paper studies the co-evolution of public and private sector debt in advanced countries since 1870. We find that in advanced economies financial stability risks have come from private sector credit booms ...

Labor markets in the global financial crisis
The impact of the global financial crisis on labor markets varied widely from country to country. In the United States, the unemployment rate nearly doubled from its pre-recession level. The rate rose much less in the United Kingdom and barely changed in Germany, despite larger declines in gross domestic product. Institutional and technological changes since the 1970s had previously made relationships between output and unemployment more homogeneous across countries. But the global financial crisis undid much of this convergence as countries adopted different labor market policies to adjust ...

The Total Risk Premium Puzzle?
The risk premium puzzle is worse than you think. Using a new database for the U.S. and 15 other advanced economies from 1870 to the present that includes housing as well as equity returns (to capture the full risky capital portfolio of the representative agent), standard calculations using returns to total wealth and consumption show that: housing returns in the long run are comparable to those of equities, and yet housing returns have lower volatility and lower covariance with consumption growth than equities. The same applies to a weighted total-wealth portfolio, and over a range of ...

Global Financial Cycles and Risk Premiums
This paper studies the synchronization of financial cycles across 17 advanced economies over the past 150 years. The comovement in credit, house prices, and equity prices has reached historical highs in the past three decades. The sharp increase in the comovement of global equity markets is particularly notable. We demonstrate that fluctuations in risk premiums, and not risk-free rates and dividends, account for a large part of the observed equity price synchronization after 1990. We also show that U.S. monetary policy has come to play an important role as a source of fluctuations in risk ...

Monetary policy when the spyglass is smudged
An accurate measure of economic slack is key to properly calibrating monetary policy. Two traditional gauges of slack have become harder to interpret since the Great Recession: the gap between output and its potential level, and the deviation of the unemployment rate from its natural rate. As a consequence, conventional policy rules based on these measures of slack generate wide-ranging policy rate recommendations. This variability highlights one of the challenges policymakers currently face.

A chronology of international business cycles through non-parametric decoding
This paper introduces a new empirical strategy for the characterization of business cycles. It combines non-parametric decoding methods that classify a series into expansions and recessions but does not require specification of the underlying stochastic process generating the data. It then uses network analysis to combine the signals obtained from different economic indicators to generate a unique chronology. These methods generate a record of peak and trough dates comparable, and in one sense superior, to the NBER's own chronology. The methods are then applied to 22 OECD countries to obtain ...
