We study complexity in the market for securitized products, a market at the heart of the financial crisis of 2007-2009. The complexity of these products rose substantially in the years preceding the financial crisis. We find that securities in more complex deals default more and have lower...

This paper reviews recent literature on how households make decisions regarding residential mortgages. We focus on recent publications in Real Estate Economics that are related to households' mortgage choices. The paper covers four areas: (1) the role of intermediaries such as mortgage brokers;...

We analyze the entry of new credit rating agencies into structured finance products. Our setting is unique as we study a period in which the incumbents' reputation was extremely poor and the benefit of more fee income from inflating ratings was low. We find entrants cater to issuers by issuing...

We document economically important correlations between children's future credit outcomes and their parents' credit risk scores, default, and the extent of credit constraints - intergenerational linkages in household credit. Using observations on siblings, we find that the linkages are due to...

What makes an asset institutional-quality? This paper proposes that one reason is the existing concentration of delegated investors in a market through a liquidity channel. Consistent with this intuition, it documents differences in investor composition across US cities and shows that delegated...

We survey the properties of commercial real estate (CRE) as an asset class. We first illustrate its importance relative to the US economy and to other asset classes. We then discuss CRE ownership patterns over time. While the academic literature has emphasized Real Estate Investment Trusts...

I examine tenure and mortgage choice in an equilibrium model in which households make decisions as if they discount hyperbolically rather than exponentially. Overall, hyperbolic discounting does not seem to explain the high rates of home ownership or portfolio concentration in housing in the...

We provide an analytic valuation framework to value second mortgages and first lien mortgages when owners can take out a second lien. We then use the framework to value mortgage-backed securities (MBS) and, in particular, quantify the greater risk associated with MBS backed by first liens that...

We propose that financial institutions can act as asset insulators, holding assets for the long run to protect their valuations from consequences of exposure to financial markets. We illustrate the empirical relevance of this theory for the balance sheet behavior of a large class of...

We document what fraction of the housing stock in US cities is affordable to different family types. Rather than looking at what fraction of their income people actually pay in rent in each city, we look at the extent to which the housing stock is affordable using discrete housing expenditure...
