Experimental Markets and Chamberlin's Excess Trading Conjecture
Ted Bergstrom, University of California, Santa Barbara
ABSTRACT: Edward Chamberlin conjectured that the number of
trades in realistic trading systems is likely to exceed that
predicted by competitive equilibrium theory. He supported this
conjecture by data from a large number of classroom experiments
and with a plausible argument based on a numerical example. This
paper states and proves a theorem that supports and illuminates
Chamberlin's intuition, supplies examples of trading processes
that lead to excess trading, and presents some additional
experimental evidence.
