本文提出了一个具有邻域效应的个体决策模型。邻里效应指的是在一个共同的邻里中，个人决策与其他人的决策和特征之间的相互依赖关系。因此，邻里效应是社会互动的形式;事实上，这些术语在许多情况下似乎是可以互换的。在经济学中，人们越来越认识到邻里效应在解释一系列个人行为中可能发挥重要作用;丰富的经验和理论文献已经发展。这方面工作的一个缺点是理论和数学之间缺乏强有力的联系。本文针对这一局限性，提供了一个模型的多项式选择与邻域效应。该模型代表了William Brock和Steven Durlauf（2001 a，B）的二元选择模型的推广。该模型是计量经济学上可实现的，因此有可能允许结构估计的邻域效应。第一节概述了一个基本的选择模型与邻里效应。第二节专门使用多项logit框架的结构。第三节考虑计量经济学的实施。第四节讨论了该框架的局限性，并提出了一些研究方向。所有定理的证明可以在Brock和Durlauf（2001 c）中找到。
This paper provides a model of individual decisionmaking in the presence of neighborhood effects. By neighborhood effects, we refer to interdependencies between individual decisions and the decisions and characteristics of others within a common neighborhood. As such, neighborhood effects are forms of social interactions; in fact the terms would seem to be interchangeable in many contexts. Within economics, there has developed an increasing recognition that neighborhood effects play a possibly major role in explaining a range of individual behaviors; rich empirical and theoretical literatures have developed. A failing of much of this work is the absence of strong connections between theory and empirics. This paper addresses this limitation by providing a model of multinomial choice with neighborhood effects. The model represents a generalization of the binary choice model of William Brock and Steven Durlauf (2001a,b). The model is econometrically implementable and so has the potential of allowing for structural estimation of neighborhood effects. Section I outlines a basic choice model with neighborhood effects. Section II specializes the structure using a multinomial logit framework. Section III considers econometric implementation. Section IV discusses some limitations of the framework and proposes some research directions. Proofs of all theorems may be found in Brock and Durlauf (2001c).
