Distribution and Dynamics in a Simple Tax Regime Transition
We examine transitions between excise tax and license fee regimes in the laboratory. The regimes have matched equilibrium Marshallian surplus, but license fees generate more tax revenue. The license fees are large “avoidable costs,” known to hamper competitive equilibrium convergence. With moderately experienced subjects, the prolonged transition to the license fee equilibrium has these features: (1) Prices below equilibrium levels, resulting in firm losses; (2) Marshallian surplus above equilibrium levels; and (3) transitional windfalls for the tax authority. With highly experienced subjects, license fees lead to the instability and lower seller profits and efficiency observed in past avoidable cost markets.Tax Regime Transitions, Avoidable Costs, Double Auctions, Experimental Methods.

Avoidable Cost: Ride a Double Auction Roller Coaster.
The double auction trading institution has been highly efficient across diverse marginal-cost market structures, whether human subjects or 'zero-intelligence' robots populated those markets. Accordingly, many researchers suspect that double auction performance transcends market structure and agent strategy. But the authors show that large avoidable costs undermine the efficiency and stability of human subject double auctions and these low human efficiencies are simultaneously well above zero-intelligence efficiencies. Their results dramatically illustrate the potential havoc wrought by highly competitive institutions when they must cope with nonconvex technologies. Copyright 1996 by American Economic Association.
A Limit of Bilateral Contracting Institutions
Nonconvexities undermine the efficiency of the usually robust "double auction" or DA market institution. We experimentally examine two modified DAs that allow for particularly rich bilateral contracting such as arbitrarily nonlinear pricing. The first allows for arbitrarily nonlinear pricing but should not necessarily promote it; the second should promote efficient nonlinear pricing. Experiments support predictions on the emergence of nonlinear pricing, but not those concerning efficiency. Coordination problems are the culprit. We conclude that institutions capable of dealing with some nonconvexities must frequently provide multilateral contracting possibilities not permitted by DA rules and other market-like bilateral contracting institutions.
