Designing Incentives for Heterogeneous Researchers
研究委托人(如政府)如何与成本未知的研究者(如疫苗开发者)签订合同,以激励其进行昂贵实验。通过贝叶斯劝说模型刻画实验形式与结果强度的差异,发现最优合同会扭曲实验以筛选研究者,且基于实验结果签约与基于实验本身签约无效率损失。
A principal (e.g., the US government) contracts with a researcher with unknown costs (e.g., a vaccine developer) to conduct a costly experiment. This contracting problem has a novel feature that captures the difference between the form of an experiment and the strength of its results: researchers face a problem of information design rather than optimal effort. Using a novel comparative static for Bayesian persuasion settings, I characterize the optimal contract and show how experimentation is distorted by the need to screen researchers. Moreover, I show that there is no loss from contracting on the experiment’s result rather than the experiment itself.
