This paper examines the impact of macroeconomic and financial sector policy announcements in the United States, the United Kingdom, the euro area, and Japan during the recent crisis on interbank credit and liquidity risk premia. Announcements of interest rate cuts, liquidity support, liability...

The global economy has a chronic shortage of safe assets which lies behind many recent macroeconomic imbalances. This paper provides a simple model of the Safe Asset Mechanism (SAM), its recessionary safety traps, and its policy antidotes. Safety traps share many common features with...

We analyze how changes in government policy affect stock prices. Our general equilibrium model features uncertainty about government policy and a government that has both economic and non-economic motives. The government tends to change its policy after performance downturns in the private...

We present a model in which banks trade toxic assets to raise funds for investment. The toxic assets generate an adverse selection problem and, as a consequence, the interbank asset market provides insufficient liquidity to finance investment. While the best investments are fully funded,...

This paper analyzes prudential controls on capital flows to emerging markets from the perspective of a Pigouvian tax that addresses externalities associated with the deleveraging cycle. It presents a model in which restricting capital inflows during boom times reduces the potential outflows...

We develop a general equilibrium model of government policy choice in which stock prices respond to political news. The model implies that political uncertainty commands a risk premium whose magnitude is larger in weaker economic conditions. Political uncertainty reduces the value of the...

We evaluate the effect of the Federal Reserve's purchase of long-term Treasuries and other long-term bonds ("QE1" in 2008-2009 and "QE2" in 2010-2011) on interest rates. Using an event-study methodology we reach two main conclusions. First, it is inappropriate to focus only on Treasury rates as...

Derivatives exposures across large financial institutions often contribute to - if not necessarily create - systemic risk. Current reporting standards for derivatives exposures are nevertheless inadequate for assessing these systemic risk contributions. In this paper, I explain how a...

This paper examines what transformed a significant, but relatively mild, financial disruption into a full-fledged financial crisis. It discusses why, although the Lehman Brothers bankruptcy was a key trigger for the global financial crisis, three other events were at least as important: the AIG...

Commercial banks are subject to regulation that restricts their investments. When banks are concerned for their reputation, however, they could self-regulate and invest more efficiently. Hence, a shadow banking that arises to avoid regulation has the potential to improve welfare. Still,...
