A model intervenes: the many faces of moral hazard
基于社会本体论，提出分析模型如何干预社会的新框架，识别特异性、可移植性和形式精确性三个关键特征，并用道德风险模型在工人补偿、银行监管和欧元主权债务危机中的应用加以说明。
This article builds on advances in social ontology to develop a new understanding of how mainstream economic modelling affects reality. We propose a new framework for analysing and describing how models intervene in the social sphere. This framework allows us to identify and articulate three key epistemic features of models as interventions: specificity, portability and formal precision. The second part of the article uses our framework to demonstrate how specificity, portability and formal precision explain the use of moral hazard models in a variety of different policy contexts, including worker compensation schemes, bank regulation and the euro-sovereign debt crisis.
