We provide new empirical evidence concerning the contentious debate over the use of historical cost (HCA) versus mark-to-market (MTM) accounting in regulating financial institutions. These accounting rules, through their interactions with capital regulations, alter financial institutions’...

After negative shocks, investors with short trading horizons are inclined or forced to sell their holdings to a larger extent than investors with longer trading horizons. This may amplify the effects of market-wide shocks on stock prices. We test the relevance of this mechanism by exploiting the...

This paper considers the economic and political drivers of sovereign default, focusing on countries rich enough to render sovereign default a ‘won’t pay’ rather than a ‘can’t pay’ phenomenon. Unlike many private contracts, sovereign debt contracts rely almost exclusively on...

We present a simple model of systemic risk and we show that each financial institution's contribution to systemic risk can be measured as its systemic expected shortfall (SES), i.e., its propensity to be undercapitalized when the system as a whole is undercapitalized. SES increases with the...

We use survey data to study American households’ propensity to default when the value of their mortgage exceeds the value of their house even if they can afford to pay their mortgage (strategic default). We find that 26% of the existing defaults are strategic. We also find that no household...

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...

This paper argues that the U.S. financial crisis is a new type of crisis: a "financial black hole." Financial black holes are characterized by the breaking-up of credit market discipline and the large-scale financing of negative NPV projects. In a theoretical model, we explain how the...

This paper develops a micro-founded general equilibrium model of the financial system composed of ultimate borrowers, ultimate lenders and financial intermediaries. The model is used to investigate the impact of uncertainty about the likelihood of governmental bailouts on leverage, interest...

Most stock exchange regulators around the world reacted to the 2007-2009 crisis by imposing bans or regulatory constraints on short-selling. Short-selling restrictions were imposed and lifted at different dates in different countries, often applied to different sets of stocks and featured...

We show that banks' cash flow exposure to interest rate risk, or income gap, plays a crucial role in their lending behavior following monetary policy shocks. In a first step, we show that the sensitivity of bank profits to interest rates increases significantly with their income gap, even when...
