We analyze financial market data in order to produce an ex-ante assessment of the economic consequences of war with Iraq. The novel feature of our analysis derives from the existence of a market for Saddam Securities,' a new future traded on an online betting exchange that pays only if Saddam...

We analyze how a wealth shift to emerging countries may lead to instability in developed countries. Investors exposed to expropriation risk are willing to pay a safety premium to invest in countries with good property rights. Domestic intermediaries compete for such cheap funding by carving out...

This paper presents a general equilibrium model with endogenous collateral constraints to study the relationship between financial development and business cycle fluctuations in a cross-section of economies with different sizes of their financial sector. The financial sector can amplify or...

We model the behavior of dealers in Over-the-Counter (OTC) derivatives markets where a small number of dealers trade with a continuum of heterogeneous clients (hedgers). Imperfect competition and (endogenous) default induce a familiar trade-off between competition and risk. Increasing the number...

We present CoMargin, a new methodology to estimate collateral requirements for central counterparties (CCPs) in derivatives markets. CoMargin depends on both the tail risk of a given market participant and its interdependence with other participants. Our approach internalizes market...

Commodity-equity and cross-commodity return co-movements rose dramatically after the 2008 financial crisis. This development took place following what has been dubbed the 'financialization' of commodity markets. We first document changes since 2000 in the intensity of speculative activity in...

This paper shows that banks that rely heavily on short-term funding engage less in maturity transformation in an attempt to decrease their exposure to rollover risk. These banks shorten both the maturity of their portfolio of loans as well as the maturity of newly issued loans. We find that the...

This paper quantifies the effects of improving public equity markets on macroeconomic aggregates and welfare. I use an open-economy extension of Angeletos (2007), where entrepreneurs face idiosyncratic productivity risk in privately held firms. They can diversify by investing in publicly traded...

This paper studies how banks simultaneously manage the two sides of their balance sheet and its implications for bank risk taking and real economic activity. First, we analyze how changes in funding affect the supply of bank loans. We then examine how the supply of credit by banks that rely more...
