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...

We examine the pricing of financial crash insurance during the 2007-2009 financial crisis in U.S. option markets. A large amount of aggregate tail risk is missing from the price of financial sector crash insurance during the financial crisis. The difference in costs of out-of-the-money put...

Since the 2008 global financial crisis, and after decades of relative neglect, the importance of the financial system and its episodic crises as drivers of macroeconomic outcomes has attracted fresh scrutiny from academics, policy makers, and practitioners. Theoretical advances are following a...

We study interventions to restore efficient lending and investment when financial markets fail because of adverse selection. We solve a design problem where the decision to participate in a program offered by the government can be a signal for private information. We charac terize optimal...

We explore a view of the crisis as a shock to investor sentiment that led to the collapse of a bubble or pyramid scheme in financial markets. We embed this view in a standard model of the financial accelerator and explore its empirical and policy implications. In particular, we show how the...

This paper makes a case that the global imbalances of the 2000s and the recent global financial crisis are intimately connected. Both have their origins in economic policies followed in a number of countries in the 2000s and in distortions that influenced the transmission of these policies...

This paper builds a dynamic general equilibrium macro-finance model with two types of borrowers: entrepreneurs who want to produce and gamblers who want to play a lottery. It links central bank's interest rate policy to expected cash flows of both types. This link enables us to study how the...

We study a model where a capital provider learns from the price of a firm’s security in deciding how much capital to provide for new investment. This feedback effect from the financial market to the investment decision gives rise to trading frenzies, where speculators all wish to trade like...

We measure the amount of income insurance and cross-sectional consumption smoothing (lending and borrowing) achieved within subgroups of states, such as regions or clubs, e.g. the club of rich states. We find that there is as much income insurance between, as well as within, regions. By...

This paper is based on presentation given at the June 2011 Conference of the Centre for Growth and Business Cycle Research at the University of Manchester. It reviews key features of the 2007-08 financial crisis, the subsequent 'great recession' and the European public debt problems; in the...
