A Model of Positive Self-Image in Subjective Assessments
提出一个机制，描述个体在主观评估自身相对能力时如何产生积极自我形象。该机制假设个体具有异质性生产函数，并基于自身函数进行能力比较，分析了任务难度、所需技能数量和人口中生产技术差异对积极自我形象的影响。
This paper suggests a mechanism that describes individuals' positive self-image in subjective assessments of their relative abilities. The mechanism assumes individuals have heterogeneous production functions that determine ability as a function of multiple skills; make skill-enhancing investments with the goal of maximizing their ability; and make ability comparisons using their own production function. Within this framework, the paper provides conditions under which there is positive self-image. Positive self-image is increasing in the ease of the task, the number of different skills needed for the task, and the variability of production technologies in the population.
