Why Cash Transfers Are Good Policy in the COVID-19 Pandemic
The COVID-19 pandemic has had an exceptionally large and negative impact on economic activity around the world. We show that cash transfers can be a useful policy tool during a pandemic. Cash transfers mitigate consumption inequality induced by the pandemic and provide incentives to individuals who are most negatively affected by lockdown policies to adhere to them.

Adverse Selection, Lemons Shocks and Business Cycles
Asymmetric information is crucial for understanding the disruption of the supply of credit. This paper studies a dynamic economy featuring asymmetric information and resulting adverse selection in credit markets. Entrepreneurs seek loans from banks for projects, but asymmetric information about entrepreneurs' riskiness causes a lemons problem: relatively safe entrepreneurs do not get funded. An increase in the riskiness of some entrepreneurs raises interest rate spreads, aggravates adverse selection, and shrinks the supply of bank credit. The model calibrated to the U.S. economy generates ...

Monetary Policy over the Life Cycle
A tighter monetary policy is generally associated with higher real interest rates on depositsand loans, weaker performance of equities and real estate, and slower growth in employment andwages. How does a household’s exposure to monetary policy vary with its age? The size andcomposition of both household income and asset portfolios exhibit large variation over the lifecycle inJapanese data. We formulate an overlapping generations model that reproduces these observationsand use it to analyze how household responses to monetary policy shocks vary over the lifecycle. Boththe signs and the ...

Asset Bubbles and Global Imbalances
What caused the housing boom and bust of the early 2000s? Capital inflows from emerging markets to developed economies can contribute to the formation of bubbles in asset prices. Those bubbles encourage the accumulation of debt, and the deleveraging of that debt exacerbates the decline in economic activity when the bubble bursts.

Asset Bubbles and Global Imbalances
We analyze the relationships between bubbles, capital flows, and economic activities in a rational bubble model with two large open economies. We establish a reinforcing relationship between global imbalances and bubbles. Capital flows from South to North facilitate the emergence and the size of bubbles in the North. Bubbles in the North in turn facilitate South-to-North capital flows. The model can simultaneously explain several stylized features of recent bubble episodes.

Why Aging Induces Deflation and Secular Stagnation
We provide a quantitative theory of deflation and secular stagnation. In our lifecycle framework, an aging population puts persistent downward pressure on the price level, real interest rates, and output. A novel feature of our theory is that it also recognizes the reactions of government policy. The central bank responds to falling prices by reducing its policy nominal interest rate, and the fiscal authority responds by allowing the public debt–gross domestic product ratio to rise.

Slow Post-Financial Crisis Recovery and Monetary Policy
Post-financial crisis recoveries tend to be slow and be accompanied by slowdowns in TFP and permanent losses in GDP. To prevent them, how should monetary policy be conducted? We address this issue by developing a model with endogenous TFP growth in which an adverse financial shock can induce a slow recovery. In the model, a welfare-maximizing monetary policy rule features a strong response to output, and the welfare gain from output stabilization is much larger than when TFP expands exogenously. Moreover, inflation stabilization results in a sizable welfare loss, while nominal GDP ...

Saving and interest rates in Japan: why they have fallen and why they will remain low
This paper quantifies the role of alternative shocks in accounting for the recent declines in Japanese saving rates and interest rates and provides some projections about their future course. We consider three distinct sources of variation in saving rates and real interest rates: changes in fertility rates, changes in survival rates, and changes in technology. The empirical relevance of these factors is explored using a computable dynamic OLG model. We find that the combined effects of demographics and slower total factor productivity growth successfully explain both the levels and the ...
