Economic Interpretations of Intergenerational Correlations
从经济学角度解释代际相关性,通过一个投资与代际决策的简单模型,预测禀赋和信贷市场如何影响代际相关性,并回顾相关实证研究的成败。
Since accurate prediction ultimately determines the usefulness of theory, our paper gives the reader a taste of some predictions derived from economic theory and some empirical successes and failures. We provide only a taste, because there are a great many economic models relevant to intergenerational correlations— such as models of educational attainment, neighborhood effects in schooling, family formation and fertility choice, occupational choice and discrimination—and quite a variety of predictions that might be derived from these models. However, a simple model of investment and intergenerational decision making can be interpreted as a conceptual aggregation of many more detailed economic models. We present such a model and from it derive one class of predictions that has received substantial attention in the empirical literature—the role of endowments and credit markets in determining intergenerational correlations.
