Title: Are Experimental Asset Markets Arbitrage-Free?

Abstract: Much of the experimental finance literature seeks to test the conditions under which asset bubbles occur in the laboratory. But if these experiments are to give us information about real-world markets, they should resemble real-world markets in some basic ways. We create an experimental asset market with a complete set of (two) state-contingent assets, whose setup is similar to the type normally employed in "bubble experiments," and compare the order book prices and realized transaction prices to similar real-world markets. We find that although opportunities for true arbitrage are rare, transaction prices differ persistently from no-arbitrage prices. This raises doubts as to whether experimental markets of this type are sufficiently liquid to serve as good proxies for real-world markets.
