FinTech Lending, Social Networks and the Transmission of Monetary Policy
One of the main channels through which monetary policy stimulus affects the real economy is mortgage borrowing. This channel, however, is weakened by frictions in the mortgage market. The rapid growth of financial technology-based (FinTech) lending tends to ease these frictions, given the higher quality services provided under this new lending model. This paper establishes that the role of FinTech lending in the monetary policy transmission is further amplified by consumers’ social networks. I provide empirical evidence for this network effect using county-level data and novel ...

Oil Prices, Exchange Rates and Interest Rates
There has been much interest in the relationship between the price of crude oil, the value of the U.S. dollar, and the U.S. interest rate since the 1980s. For example, the sustained surge in the real price of oil in the 2000s is often attributed to the declining real value of the U.S. dollar as well as low U.S. real interest rates, along with a surge in global real economic activity. Quantifying these effects one at a time is difficult not only because of the close relationship between the interest rate and the exchange rate, but also because demand and supply shocks in the oil market in turn ...

A Broader Perspective on the Inflationary Effects of Energy Price Shocks
Consumers purchase energy in many forms. Sometimes energy goods are consumed directly, for instance, in the form of gasoline used to operate a vehicle, electricity to light a home or natural gas to heat a home. At other times, the cost of energy is embodied in the prices of goods and services that consumers buy, say when purchasing an airline ticket or when buying online garden furniture made from plastic to be delivered by mail. Previous research has focused on quantifying the pass-through of the price of crude oil or the price of motor gasoline to U.S. inflation. Neither approach accounts ...

Refining the Workhorse Oil Market Model
The Kilian and Murphy (2014) structural vector autoregressive model has become the workhorse model for the analysis of oil markets. I explore various refinements and extensions of this model, including the effects of (1) correcting an error in the measure of global real economic activity, (2) explicitly incorporating narrative sign restrictions into the estimation, (3) relaxing the upper bound on the impact price elasticity of oil supply, (4) evaluating the implied posterior distribution of the structural models, and (5) extending the sample. I demonstrate that the substantive conclusions of ...
Surging House Prices Expected to Propel Rent Increases, Push Up Inflation
The inflation rates of rent and owners’ equivalent rent (OER)—the amount of rent equivalent to the cost of ownership—have declined sharply since the COVID-19 pandemic began in February 2020. However, we expect rent inflation and OER inflation to accelerate in the years to come.
U.S. 30-Year mortgage predominance doesn’t seem to delay impact of Fed rate hikes
After comparing economic data of the U.S. and other major advanced economies, we find tentative evidence that the slow adjustment of the outstanding mortgage rate in the U.S. has not played an important role in delaying the intended effects of the monetary tightening.

Wealth Inequality and Return Heterogeneity During the COVID-19 Pandemic
Wealth inequality in the U.S., measured by the top 1% wealth share, experienced dramatic changes in the first year of the COVID-19 pandemic. Economic theory suggests that the key to understanding wealth inequality is heterogeneity in the return to net worth across households. To understand the dynamics of wealth inequality during the COVID-19 pandemic, we develop a novel methodology that allows us to estimate the returns to net worth for different groups of households at relatively high frequency. We show that portfolio heterogeneity and asset price movements are the main determinants of ...
A New View of the Relationship Between Oil Prices, Gasoline Prices and Inflation Expectations
It has been considered self-evident until recently that oil prices drive inflation expectations, but new evidence calls into question this conclusion.

Mortgage Borrowing and the Boom-Bust Cycle in Consumption and Residential Investment
This paper studies the transmission of the major shocks in the U.S. housing market in the 2000s to consumption and residential investment. Using geographically disaggregated data, I show that residential investment is more responsive to these shocks than consumption, as measured by elasticities and the implied contributions to GDP growth. I develop a structural life-cycle model featuring multiple types of housing investment to understand the large responses of residential investment. Consistent with the microdata, the model generates lumpy debt accumulation, lumpy housing investment and a ...
CARES Act Likely to Blunt Mortgage Delinquency Rate Increase
Household survey data and recent unemployment forecasts provide a basis for estimating the share of mortgage borrowers that—absent the CARES Act—would have missed a mortgage payment due to the economic shutdown.
