The Home Affordable Modification Program (HAMP) was a loan modification program introduced in 2009, in the U.S., to assist highly indebted homeowners with avoiding foreclosure. This program also encouraged private lenders to offer more sustainable modifications. This paper studies the role of...

Shared-appreciation mortgage (SAM) contracts, which display payments indexed to a local house price, have been proposed as an alternative to alleviate the costs of recessions. Using a heterogeneous agent model with two types of agents (Borrowers and Savers), uninsurable idiosyncratic income...

We study the implications of regional heterogeneity within a currency union for monetary policy. We ask, first, does monetary policy mitigate or exacerbate ex-post regional dispersion over the business cycle? And second, does ex-ante regional heterogeneity increase or dampen the aggregate...

What role does stock investment play in the transmission of monetary policy to the real economy? We study this question using a New Keynesian model with heterogeneous households. Following a monetary tightening, stock market participants rebalance their investments away from stocks, in line with...

We argue that the time-varying regional distribution of housing equity influences the aggregate consequences of monetary policy through its effects on mortgage refinancing. Using detailed loan-level data, we show that regional differences in housing equity affect refinancing and spending...

We use quasi-random access to the Home Affordable Refinance Program (HARP) to identify the causal effect of refinancing a mortgage on borrower balance sheet outcomes. We find that on average, refinancing into a lower-rate mortgage reduced borrowers' default rates on mortgages and nonmortgage...

We study optimal monetary policy in a heterogeneous agent new Keynesian economy. A utilitarian planner seeks to reduce consumption inequality, in addition to stabilizing output gaps and inflation. The planner does so both by reducing income risk faced by households, and by reducing the...

Does market incompleteness radically transform the properties of monetary economies? Using an analytically tractable heterogeneous agent New Keynesian (HANK) model, we show that whether incomplete markets resolve "policy paradoxes" in the representative agent New Keynesian model (RANK) depends...

This work is based on a new Keynesian theoretical model for an advanced economy, which incorporates overlapping generations to analyze a channel through which fluctuations in household financial wealth influence aggregate demand. The optimal monetary policy, corresponding to that of a central...

We construct a theoretical model of labor markets with human capital accumulation to understand and quantify the earnings losses for young workers generated by unemployment: unemployment represents time forgone in terms of human capital accumulation, which adversely affects long-term income...
