本文概述了社会互动模型背后的经济学,并简要讨论了社会互动的实证方法。我们提出了一个简单的模型,局部相互作用,类似于Glaeser,Sacerdote和Scheinkman(1996),但使用连续的行动空间,并开始优化行为。然后,我们扩展模型,包括全球和本地的相互作用。我们建议并使用一种方法,使用城市内的总量变化,以确定当地和全球的相互作用的相对大小。我们还提出了一个模型与内生的位置选择,并使用该模型的预测,以确定跨城市的差异,是由于排序和相互作用的来源。最后,我们提出了一个简短的讨论,使用时间序列来估计广泛的社会互动。
This paper presents an overview of the economics that lies behind social interaction models and briefly discusses the empirical approaches to social interactions. We present a simple model with local interactions, similar to Glaeser, Sacerdote and Scheinkman (1996) but using aa continuous action space and starting with optimizing behavior. We then extend the model to include both global and local interactions. We suggest and use a methodology for using variation of intra-city aggregates to identify the relative sizes of local and global interactions. We also present a model with endogenous location choice and use the predictions of that model to identify the sources of cross-city variance that are due to sorting and interaction. Finally, we present a brief discussion of using time-series to estimate the social interactions in broad aggregates.
