Housing affordability is the main policy challenge for many large cities in the world. Zoning changes, rent control, housing vouchers, and tax credits are the main levers employed by policy makers. But how effective are they at combatting the affordability crisis? We build a new framework to...

How does one's childhood neighborhood shape political engagement later in life? We leverage a natural experiment that moved children out of disadvantaged neighborhoods to study effects on their voting behavior more than a decade later. Using linked administrative data, we find that children who...

We use variation in mortgage modifications to disentangle the impact of reducing long-term obligations with no change in short-term payments ("wealth"), and reducing short-term payments with approximately no change in long-term obligations ("liquidity"). Using regression discontinuity and...

The United States government devotes about $40 billion each year to means-tested housing programs, plus another $6 billion or so in tax expenditures on the Low Income Housing Tax Credit (LIHTC). What exactly do we spend this money on, why, and what does it accomplish? We focus on these...

After the collapse of housing markets during the Great Depression, the U.S. government played a large role in shaping the future of housing finance and policy. Soon thereafter, housing markets witnessed the largest boom in recent history. The objective in this paper is to quantify the...

Should the national government undertake policies aimed at strengthening the economies of particular localities or regions? Agglomeration economies and human capital spillovers suggest that such policies could enhance welfare. However, the mere existence of agglomeration externalities does not...

We show that the Federal Housing Administration (FHA), from its inception in the 1930s, did not insure mortgages in low income urban neighborhoods where the vast majority of urban Black Americans lived. The agency evaluated neighborhoods using block-level information collected by New Deal relief...

In many recent location choice models, households randomly vary with respect to their utility of living in a location. We demonstrate that the distribution generating this randomness is fundamentally not identifiable from location choice data and as a result the optimal allocation as chosen by a...

This paper surveys the effects of two of the most important federal policies toward housing: the "implicit subsidy" for owner-occupied housing in the income tax code, and the provision of housing for low income families at rents below cost. Emphasis is placed on the methodological problems that...

Low-income families in the United States tend to live in neighborhoods that offer limited opportunities for upward income mobility. One potential explanation for this pattern is that families prefer such neighborhoods for other reasons, such as affordability or proximity to family and jobs. An...
