Rehypothecation refers to the practice of reusing (selling or pledging as collateral) an asset that has already been pledged as collateral for a cash loan. In high inflation economies, rehypothecation improves economic welfare, but there is generally too much of it. We find that regulatory...

Rehypothecation refers to the practice of re-using (selling or pledging as collateral) an asset that has already been pledged as collateral for a loan. We develop a dynamic general equilibrium monetary model where an “asset shortage” motivates the rehypothecation of assets. We find that in...

Conventional theory suggests that fiat money will have value in capitalpoor economies. We demonstrate that fiat money may also have value in capital-rich economies, if the price of capital is excessively volatile. Excess asset-price volatility is generated by news; information that has no social...

When commitment is lacking, intertemporal trade is facilitated with the use of exchange media--interpreted broadly to include monetary and collateral assets. We study the properties of a model commonly used to motivate monetary exchange, extended to include a physical asset whose expected...

We modify the Diamond-Dybvig model studied in Green and Lin to incorporate a self-interested banker who has a private record-keeping technology. A public record-keeping device does not exist. We find that there is a trade-off between sophisticated contracts that possess relatively good...

We show that the dispersion of private valuation reduces market liquidity and allocative efficiency of a dynamic OTC market. In this decentralized market, traders have time varying and heterogeneous private value over the asset and dealers act as competing mechanism designers. We characterize...

We develop a model of monetary exchange in over-the-counter (OTC) markets and use it to study the effects of inflation on asset prices, as well as on standard measures of financial liquidity, such as the size of bid-ask spreads, trade volume, and the incentives of dealers to supply immediacy,...

I build a dynamic model of the shadow banking system that intermediates funds through the interbank repo market to understand its efficiency and stability. The model emphasizes a key friction: the maturity mismatch between the short-term repo and the long-term investment that banks need to...

This study explores the relationship between external dependent economic structure, surplus monetary liquidity and real estate bubbles in China. Employing monthly data from 28 Chinese provinces over the period 2004-2005, we test whether real estate bubbles are caused by structural surplus...

In this paper we use micro data on both trade and production for a sample of large Chinese manufacturing firms in the footwear industry from 2002-2006 to estimate an empirical model of export demand, pricing, and market participation by destination market. We use the model to construct indexes...
