Rowell and Connelly offer a detailed description of the genesis of the term moral hazard, by identifying salient changes in economic thought, which are identified within the medieval theological and probability literature. Their paper compares and contrasts the predominantly normative conception of moral hazard found within the insurance-industry literature with the largely positive interpretations found within the economic literature. Often what is described as "moral hazard" in the insurance literature is upon closer reading, a description of the closely related concept, adverse selection.
