Closing Large Open Economy Models
A large class of international business cycle models admits multiple locally isolated deterministic steady states, if the elasticity of substitution between traded goods is sufficiently low. I explore the conditions under which such multiplicity occurs and characterize the dynamic properties in the neighborhood of each steady state. Models with standard incomplete markets, portfolio costs, a debt-elastic interest rate, or an overlapping generations framework allow for multiple steady states, if the model features multiple steady states under financial autarchy. If the excess demand for the ...

What to expect from the lower bound on interest rates: evidence from derivatives prices
This paper analyzes the effects of the lower bound for interest rates on the distributions of inflation and interest rates. We study a stylized New Keynesian model where the policy instrument is subject to a lower bound to motivate the empirical analysis. Two equilibria emerge: In the “target equilibrium,” policy is unconstrained most or all of the time, whereas in the “liquidity trap equilibrium,” policy is mostly or always constrained. We use options data on future interest rates and inflation to study whether the decrease in the natural real rate of interest leads to forecast ...

Interest Rate Dynamics, Variable-Rate Loan Contracts, and the Business Cycle
The interest rate at which US firms borrow funds has two features: (i) it moves in a countercyclical fashion and (ii) it is an inverted leading indicator of real economic activity: low interest rates forecast booms in GDP, consumption, investment, and employment. We show that a Kiyotaki-Moore model accounts for both properties when business-cycle movements are driven, in a significant way, by animal spirit shocks to credit-financed investment demand. The credit-based nature of such self-fulfilling equilibria is shown to be essential: the dynamic correlation between current loanable funds rate ...

The 2012 Eurozone Crisis and the ECB’s OMT Program: A Debt-Overhang Banking and Sovereign Crisis Interpretation
This paper develops a model to interpret the 2012 eurozone crisis and the ECB?s policy response. In the model, bank lending is distorted by debt overhang, banks hold sovereign bonds, and the government guarantees the bailout of bank creditors. A self-fulfilling pessimistic view of the economy can trigger a banking and sovereign crisis: with pessimistic economic expectations, the value of sovereign bonds declines, the bank risk of default rises, and the debt overhang distortion worsens; this leads to a contraction in bank lending and to a decline in economic activity, which confi rms the ...

Self-Fulfilling Debt Dilution: Maturity and Multiplicity in Debt Models
We establish that creditor beliefs regarding future borrowing can be self-fulfilling, leading to multiple equilibria with markedly different debt accumulation patterns. We characterize such indeterminacy in the Eaton-Gersovitz sovereign debt model augmented with long maturity bonds. Two necessary conditions for the multiplicity are: (i) the government is more impatient than foreign creditors, and (ii) there are deadweight losses from default; both are realistic and standard assumptions in the quantitative literature. The multiplicity is dynamic and stems from the self-fulfilling beliefs of ...

Debt-Overhang Banking Crises
This paper studies how a worsening of the debt overhang distortion on bank lending can explain banking solvency crises that are accompanied by a plunge of bank asset values and by a severe contraction of lending and economic activity. Since the value of bank assets depends on economic prospects, a pessimistic view of the economy can be self-fulfilling and can trigger a financial crisis: If economic prospects are poor, bank asset values decline, the bank risk of default rises, and the associated debt overhang distortion worsens. The worsening of the distortion leads to a contraction in bank ...

Wealth and Volatility
Periods of low household wealth in United States macroeconomic history have also been periods of high business cycle volatility. This paper develops a simple model that can exhibit self-fulfilling fluctuations in the expected path for unemployment. The novel feature is that the scope for sunspot-driven volatility depends on the level of household wealth. When wealth is high, consumer demand is largely insensitive to unemployment expectations and the economy is robust to confidence crises. When wealth is low, a stronger precautionary motive makes demand more sensitive to unemployment ...

Collateral Reuse and Financial Stability
The isolated effects of collateral reuse on financial stability are ambiguous and understudied. While greater collateral reuse can guarantee more payments with fewer assets, it can also increase the exposure to potential drops in collateral price. To analyze these tradeoffs, we develop a financial network model with endogenous asset pricing, multiple equilibria, and equilibrium selection. We find that more collateral reuse decreases the likelihood of the worst equilibrium (crisis), with varying effects depending on the network structure. Therefore, collateral reuse can unambiguously improve ...

Natural amenities, neighborhood dynamics, and persistence in the spatial distribution of income
We present theory and evidence highlighting the role of natural amenities in neighborhood dynamics, suburbanization, and variation across cities in the persistence of the spatial distribution of income. Our model generates three predictions that we confirm using a novel database of consistent-boundary neighborhoods in U.S. metropolitan areas, 1880{2010, and spatial data for natural features such as coastlines and hills. First, persistent natural amenities anchor neighborhoods to high incomes over time. Second, downtown neighborhoods in coastal cities were less susceptible to the ...

Sovereign Default: The Role of Expectations
We study a variation of the standard model of sovereign default, as in Aguiar and Gopinath (2006) or Arellano (2008), and show that this variation is consistent with multiple interest rate equilibria. Some of those equilibria correspond to the ones identified by Calvo (1988), where default is likely because rates are high, and rates are high because default is likely. The model is used to simulate equilibrium movements in sovereign bond spreads that resemble sovereign debt crises. It is also used to discuss lending policies similar to the ones announced by the European Central Bank in 2012.
