Trade and Labor Market Dynamics: General Equilibrium Analysis of the China Trade Shock
We develop a dynamic trade model with spatially distinct labor markets facing varying exposure to international trade. The model captures the role of labor mobility frictions, goods mobility frictions, geographic factors, and input-output linkages in determining equilibrium allocations. We show how to solve the equilibrium of the model and take the model to the data without assuming that the economy is at a steady state and without estimating productivities, migration frictions, or trade costs, which can be difficult to identify. We calibrate the model to 22 sectors, 38 countries, and 50 U.S. ...

Incorporating Diagnostic Expectations into the New Keynesian Framework
Diagnostic expectations constitute a realistic behavioral model of inference. This paper shows that this approach to expectation formation can be productively integrated into the New Keynesian framework. Diagnostic expectations generate endogenous extrapolation in general equilibrium. We show that diagnostic expectations generate extra amplification in the presence of nominal frictions; a fall in aggregate supply generates a Keynesian recession; fiscal policy is more effective at stimulating the economy. We perform Bayesian estimation of a rich medium-scale model that incorporates consensus ...

Housing Wealth and Consumption: The Role of Heterogeneous Credit Constraints
We quantify the role of heterogeneity in households’ financial constraints in explaining the large decline in consumption between 2006 and 2009. Using household-level data, we show that in addition to a direct effect of changes in house prices, there are sizable indirect effects from general equilibrium feedback and bank health. About 60% of the aggregate response of consumption to changes in house prices is explained by ex-ante and ex-post financial constraints, where only a specific set of households face binding ex-post financial constraints as a result of declining house prices. We find ...

Uncertainty, Financial Frictions, and Investment Dynamics
Micro- and macro-level evidence indicates that fluctuations in idiosyncratic uncertainty have a large effect on investment; the impact of uncertainty on investment occurs primarily through changes in credit spreads; and innovations in credit spreads have a strong effect on investment, irrespective of the level of uncertainty. These findings raise a question regarding the economic significance of the traditional "wait-and-see" effect of uncertainty shocks and point to financial distortions as the main mechanism through which fluctuations in uncertainty affect macroeconomic outcomes. The ...

Institutional Housing Investors and the Great Recession
Before the Great Recession, residential institutional investors predominantly bought and rented out condos, but then they increased their market share of rental houses from 17 percent in 2001 to 28 percent in 2018. Along with this change, rental survey data show that the annual house operating-cost premium of institutional investors relative to homeowners fell from 44 percent in 2001 to 28 percent in 2015. To measure how these reduced costs affected the housing bust of 2007–2011, I build a heterogeneous agent model of the housing market featuring corporate investors and two types of ...

Debt Limits and Credit Bubbles in General Equilibrium
We provide a novel characterization of self-enforcing debt limits in a general equilibrium framework of risk sharing with limited commitment, where defaulters are subject to recourse (a fractional loss of current and future endowments) and exclusion from future credit. We show that debt limits are exactly equal to the present value of recourse plus a credit bubble component. We provide applications to models of sovereign debt, private collateralized debt, and domestic public debt. Implications include an original equivalence mapping among distinct institutional arrangements, thereby ...

How Big is the Wealth Effect? Decomposing the Response of Consumption to House Prices
We investigate the effect of declining house prices on household consumption behavior during 2006-2009. We use an individual-level dataset that has detailed information on borrower characteristics, mortgages and credit risk. Proxying consumption by individual-level auto loan originations, we decompose the effect of declining house prices on consumption into three main channels: wealth effect, household financial constraints, and bank health. We find a negligible wealth effect. Tightening householdlevel financial constraints can explain 40-45 percent of the response of consumption to declining ...

Mortgages and Monetary Policy
Mortgages are long-term loans with nominal payments. Consequently, under incomplete asset markets, monetary policy can affect housing investment and the economy through the cost of new mortgage borrowing and real payments on outstanding debt. These channels, distinct from traditional real rate channels, are embedded in a general equilibrium model. The transmission mechanism is found to be stronger under adjustable- than fixed-rate mortgages. Further, monetary policy shocks affecting the level of the nominal yield curve have larger real effects than transitory shocks, affecting its slope. ...

Occupation Mobility, Human Capital and the Aggregate Consequences of Task-Biased Innovations
We construct a dynamic general equilibrium model with occupation mobility, human capital accumulation and endogenous assignment of workers to tasks to quantitatively assess the aggregate impact of automation and other task-biased technological innovations. We extend recent quantitative general equilibrium Roy models to a setting with dynamic occupational choices and human capital accumulation. We provide a set of conditions for the problem of workers to be written in recursive form and provide a sharp characterization for the optimal mobility of individual workers and for the aggregate supply ...

Discount Shock, Price-Rent Dynamics, and the Business Cycle
The price-rent ratio in commercial real estate is highly volatile, and its variation comoves with the business cycle. To account for these two facts, we develop a dynamic general equilibrium model that explicitly introduces a rental market and incorporates the liquidity constraint on an individual firm's production as a key ingredient. Our estimation identifies the discount shock as the most important factor in driving price-rent dynamics and linking the dynamics in the real estate market to those in the real economy. We illustrate the importance of the liquidity premium and endogenous total ...
