Volatility in Home Sales and Prices: Supply or Demand?
We use a housing search model and data on individual home listings to decompose fluctuations in home sales and price growth into supply or demand factors. Simulations of the estimated model show that housing demand drives short-run fluctuations in home sales and prices, while variation in supply plays only a limited role. We consider two implications of these results. First, we show that reduction of supply was a minor factor relative to increased demand in the tightening of housing markets during COVID-19. New for-sale listings would have had to expand 30 percent to keep the rate of price ...

On the Geographic Scope of Retail Mortgage Markets
In this note, we first discuss why markets for mortgage originations are likely to be national in scope. We then show that even if mortgage markets were local, they would be unconcentrated. Finally, we test for an empirical relationship between the local concentration of mortgage lending and changes in mortgage rates and find essentially no correlation of concentration and rates.

Measuring Mortgage Credit Availability : A Frontier Estimation Approach
We construct a new measure of mortgage credit availability that describes the maximum amount obtainable by a borrower of given characteristics. We estimate this "loan frontier" using mortgage originations data from 2001 to 2014 and show that it reflects a binding borrowing constraint. Our estimates reveal that the expansion of mortgage credit during the housing boom was substantial for all borrowers, not only for low-score or low-income borrowers. The contraction was most pronounced for low-score borrowers. Using variation in the frontier across metropolitan areas over time, we show that ...

The Effect of Mortgage Forbearance on House Prices During COVID-19
The contrast between the labor market and house prices during the pandemic has been stark. In this note, we document a strong positive relationship between forbearance takeup and house price growth at the county level, controlling for the unemployment rate and other factors.

Can More Housing Supply Solve the Affordability Crisis? Evidence from a Neighborhood Choice Model
We estimate a neighborhood choice model using 2014 American Community Survey data to investigate the degree to which new housing supply can improve housing affordability. In the model, equilibrium rental rates are determined so that the number of households choosing each neighborhood is equal to the number of housing units in each neighborhood. We use the estimated model to simulate how rental rates would respond to an exogenous increase in the number of housing units in a neighborhood. We find that the rent elasticity is low, and thus marginal reductions in supply constraints alone are ...

The Propagation of Demand Shocks Through Housing Markets
Housing demand stimulus produces a multiplier effect by freeing up owners attempting to sell their current home, allowing them to re-enter the market as buyers and triggering a chain of further transactions. Exploiting a shock to first-time home buyer demand caused by the 2015 surprise cut in Federal Housing Administration mortgage insurance premiums, we find that homeowners buy their next home sooner when the probability of their current home selling increases. This effect is especially pronounced in cold housing markets, in which homes take a long time to sell. We build and calibrate a ...
