Abstract

The study reports on the ability of competing models of market information integration and dissemination to explain the behavior of simple laboratory markets for a one-period security. Returns to the security depended upon a randomly drawn state of nature. Some agents (insiders), whose identity was unknown to other agents, knew the state before the markets opened. With replication of market conditions the predictions of a fully revealing rational-expectations model are relatively accurate. Prices adjusted immediately to near rational-expectations prices; profits of insiders were virtually indistinguishable from noninsiders; and efficiency levels converged to near 100 percent.

Asset Valuation in an Experimental Market

Robert Forsythe, Thomas R. Palfrey and Charles R. Plott (1982) “Asset Valuation in an Experimental Market." Econometrica, Vol. 50, No. 3 (May, 1982), pp. 537-567. JSTOR |via CYCU

==original abstract==

The time path of asset prices is studied within a stationary experimental environment. After several replications prices converge to a perfect foresight equilibrium. A sequential market having an “informational trap" and a futures market are also studied.

實驗簡述:

對 certificate 雙邊喊價 (double-auction), 每人一開始持有若干 (2或3) 張 certificates
持有股票, 可得股利;
- 股利每年分兩期, A 和 B 期給付;
- 但實驗中共有三種 type 的人; 每人在A、B期可獲之股利並不相同 (如 Table I 所示)
  原文:
  Because of these differences, there are gains from exchange with one individual selling the certificate to
  another. (註: 這樣設定也是為了形成負斜率的需求線, 見下圖)
不能 short-sale
可多次喊價
共進行 5 場實驗 (Experiment 1-5); 每次 8-9 人
