A growing literature (i.e. Jaffee, Lynch, Richardson, and Van Nieuwerburgh, 2009, Acharya and Schnabl, 2009) argues that securitization improves financial stability if the securitized assets are held by capital market participants, rather than financial intermediaries. I construct a quantitative...

One of the roots of the recent global financial crisis has been seen in the design of subprime mortgage contract leading to high sensitivity of such type of loans to house price changes. The market of subprime loans, especially in the last years preceding the crisis, has been highly financed by...

The confluence of three trends in the U.S. residential housing market - rising home prices, declining interest rates, and near-frictionless refinancing opportunities - led to vastly increased systemic risk in the financial system. Individually, each of these trends is benign, but when they occur...

Can inflation cure mortgage debt overhang and mitigate the severity of housing busts? Focusing on the Great Recession, I address this question through the lens of a quantitative macroeconomic model of illiquid housing, endogenous mortgage pricing, and equilibrium default. First, I show that an...

We provide empirical evidence of the causal effects of changes in financial intermediaries' net worth on the aggregate economy. Our strategy identifies financial shocks as high-frequency changes in the market value of intermediaries' net worth in a narrow window around their earnings...

After the global financial crisis, there is greater awareness of the need to understand the interactions between the financial sector and the real economy and hence the potential for financial instability.  Data from the financial flow of funds, previously relatively neglected, are now seen as...

Short-term collateralized debt, such as demand deposits and money market instruments - private money, is efficient if agents are willing to lend without producing costly information about the collateral backing the debt. When the economy relies on such informationally-insensitive debt, firms...

The global fall in interest rates in recent decades has raised the possibility of a negative natural rate of interest. The secular stagnation hypothesis argues that a negative natural rate of interest is the underlying cause of the Great Recession. In this paper I demonstrate the role of bubbles...

Pecuniary externalities in models with financial friction justify macroprudential policies for preventing economic agents' excessive risk taking. We extend the Diamond and Rajan (2012) model of banks with the production factors and explore how a pecuniary externality affects a bank's leverage....
