Standardized classroom experiments provide evidence about how well scientific results reproduce when nearly identical methods are used. We use a sample of around 20,000 observations to test reproducibility of behaviour in trading and ultimatum bargaining. Double-auction results are highly reproducible and are close to equilibrium predictions about prices and quantities from economic theory. Our sample also shows robust correlations between individual surplus and trading order, and autocorrelation of successive price changes, which test different theories of price dynamics. In ultimatum bargaining, the large dataset provides sufficient power to identify that equal-split offers are accepted more often and more quickly than slightly unequal offers. Our results imply a general consistency of results across a variety of different countries and cultures in two of the most commonly used designs in experimental economics.

标准化的课堂实验提供了证据，表明使用几乎相同的方法时，科学结果的再现效果如何。我们使用大约20,000个观察值的样本来测试交易和最后通bar讨价还价行为的可重复性。双重拍卖的结果具有很高的可重复性，并且接近经济理论关于价格和数量的均衡预测。我们的样本还显示了单个盈余和交易订单之间的稳健相关性，以及连续价格变化的自相关性，从而检验了不同的价格动态理论。在最后通bar的讨价还价中，大型数据集提供了足够的能力来识别比等分的不平等要约更频繁，更快速地接受均等的要约。
