Equilibrium Block Trading and Asymmetric Information
Published: 03/01/1990 | DOI: 10.1111/j.1540-6261.1990.tb05081.x
DUANE J. SEPPI
This paper investigates the existence of equilibria with information‐based block trading in a multiperiod market when no investor is constrained to block trade. Attention is restricted to equilibria in which a strategic uninformed institution (i.e., one which is forced to rebalance its portfolio but is free to choose an optimal rebalancing strategy) is willing to trade a block rather than “break up” the block into a series of smaller trades. Examples of such equilibria are found and analyzed.
Futures Manipulation with “Cash Settlement”
Published: 09/01/1992 | DOI: 10.1111/j.1540-6261.1992.tb04666.x
Praveen Kumar, DUANE J. SEPPI
This paper investigates the susceptibility of futures markets to price manipulation in a two‐period model with asymmetric information and “cash settlement” futures contracts. Without “physical delivery,” strategies based on “corners” or “squeezes” are infeasible. However, uninformed investors still earn positive expected profits by establishing a futures position and then trading in the spot market to manipulate the spot price used to compute the cash settlement at delivery. We also show that as the number of manipulators grows, profits from manipulation fall to zero. However, even in the limit, manipulation still has a nontrivial impact on market liquidity. More broadly, we interpret manipulation as a form of endogenous “noise trading” which can arise in multiperiod security markets.
Equilibrium Forward Curves for Commodities
Published: 12/17/2002 | DOI: 10.1111/0022-1082.00248
Bryan R. Routledge, Duane J. Seppi, Chester S. Spatt
We develop an equilibrium model of the term structure of forward prices for storable commodities. As a consequence of a nonnegativity constraint on inventory, the spot commodity has an embedded timing option that is absent in forward contracts. This option's value changes over time due to both endogenous inventory and exogenous transitory shocks to supply and demand. Our model makes predictions about volatilities of forward prices at different horizons and shows how conditional violations of the ‘Samuelson effect’ occur. We extend the model to incorporate a permanent second factor and calibrate the model to crude oil futures data.
