We develop a theory of financial intermediary leverage cycles in the context of a dynamic model of the macroeconomy. The interaction between a production sector, a financial intermediation sector, and a household sector gives rise to amplification of fundamental shocks that affect real economic...

In the conduct of monetary policy, there exists a risk-return trade-off between financial conditions and financial stability, which complements monetary policy's traditional trade-off between inflation and real activity. The trade-off exists even if monetary policy does not target financial...

The concentration of risk within financial system is considered to be a source of systemic instability. We propose a theory to explain the structure of the financial system and show how it alters the risk taking incentives of financial institutions. We build a model of portfolio choice and...

We construct a new systemic risk measure that quantifies vulnerability to fire-sale spillovers using detailed regulatory balance sheet data for U.S. commercial banks and repo market data for broker-dealers. Even for moderate shocks in normal times, fire-sale externalities can be substantial. For...

This paper develops a model of financial institutions that borrow short term and invest in longterm assets that can be traded in frictionless markets. Because these financial intermediaries perform maturity transformation, they are subject to potential runs. We derive distinct liquidity,...

This paper explores financial stability policies for the shadow banking system. I tie policy options to economic mechanisms for shadow banking that have been documented in the literature. I then illustrate the role of shadow bank policies using three examples: agency mortgage real estate...

In standard Walrasian macro-finance models, pecuniary externalities such as fire sales lead to overinvestment in illiquid assets or underprovision of liquidity. We investigate whether imperfect competition (Cournot) improves welfare through internalizing the externality and find that this is far...

Global liquidity refers to the volumes of financial flows—largely intermediated through global banks and non-bank financial institutions—that can move at relatively high frequencies across borders. The amplitude of responses to global conditions like risk sentiment, discussed in the context...

A 2012 paper by Goodhart, Kashyap, Tsomocos, and Vardoulakis (GKTV) proposes a dynamic general equilibrium framework that provides a conceptual - and to some extent quantitative - framework for the analysis of macroprudential policies. The distinguishing feature of GKTV's paper relative to any...

We summarize and evaluate Fannie Mae and Freddie Mac's credit risk transfer (CRT) programs, which have been used since 2013 to shift a portion of credit risk on more than $1.8 trillion of mortgages to private sector investors. We argue that the CRT programs have been successful in reducing the...
