We build an equilibrium model of commodity markets in which speculators are capital constrained, and commodity producers have hedging demands for commodity futures. Increases in producers' hedging demand or speculators' capital constraints increase hedging costs via price-pressure on futures....

We explore the design of climate stress tests to assess and manage macro-prudential risks from climate change in the financial sector. We review the climate stress scenarios currently employed by regulators, highlighting the need to (i) consider many transition risks as dynamic policy choices;...

We examine the dynamics of a country’s growth, consumption, and sovereign debt, assuming that the government is myopic and wants to maximize short-term, self-interested spending. Surprisingly, government myopia can increase a country’s access to external borrowing. In turn, access to...

We study interbank lending and asset sales markets in which banks with surplus liquidity have market power vis-à-vis banks needing liquidity, frictions arise in lending due to moral hazard, and assets are bank-specific. Surplus banks ration lending and instead purchase assets from needy banks,...

The headline numbers appear to show that even as banks and financial intermediaries suffered large credit losses in the financial crisis of 2007-09, they raised substantial amounts of new capital, both from private investors and through government-funded capital injections. However, on closer...

The global imbalance explanation of the financial crisis of 2007-09 suggests that demand for riskless assets from countries with current account surpluses created fragility in countries with current account deficits, most notably, in the United States. We examine this explanation by analyzing...

We show that financial sector bailouts and sovereign credit risk are intimately linked. A bailout benefits the economy by ameliorating the under-investment problem of the financial sector. However, increasing taxation of the non-financial sector to fund the bailout may be inefficient since it...
