The Social Experiment Market
基于143个社会实验的信息和电话访谈，分析了社会实验市场的买卖双方，包括目标人群、干预类型、设计趋势、资金来源、行业集中度及经济学家的角色。
In social experiments, individuals, households, or organizations are randomly assigned to two or more policy interventions. Elsewhere, we have summarized 143 experiments completed by autumn 1996. Here, we use the information we have gathered on these experiments and findings from informal telephone interviews to investigate the social experiment market--the buyers and sellers in the market that governs the production of experiments. We discuss target populations, types of interventions tested, trends in design, funding sources, industry concentration, the role of economists in social experimentation, the reasons few social experiments have been conducted outside the United States, and the future of the social experiment market.
