Social Distance and Social Decisions
构建了一个社会距离模型，用于理解社会决策。模型显示，初始社会位置相近的个体互动频繁，而社会距离远的个体互动很少，社会阶层在其中起主导作用，并讨论了该模型对教育选择和生育决策等社会决策的启示。
A model of social distance is presented that is useful for understanding social decisions. Status and conformity in previous models are discussed, and then a generalization is described. In this generalization agents have inherited positions in social space and an expected value of trade between two individuals as a function of the difference in their initial positions. An example of this system is constructed in which there is class stability. Agents who are initially close interact strongly while those who are socially distant have little interaction. In this example inherited social position, which may be interpreted as social class, plays a dominant role. The relevance of this model to social decisions such as the choice of educational attainment and childbearing is discussed in the context of specific ethnographic examples. Class position may play a dominant role in these decisions.
