How the Market Solves an Assignment Problem: The Matching of Lawyers with Legal Claims
用律师市场的晋升和离职数据，说明律师与法律索赔存在正向匹配，高质律师处理大额索赔，律所的终身制起到筛选作用。
In the market for lawyers, observable data on promotion and turnover can be explained by reference to the idea that there is positive assortative mating of lawyers and legal claim s. There is a scale-of-resources effect, under which it is optimal to assign larger claims to lawyers of higher quality. In a law firm, th e institution of "tenure" performs a sorting function. Lawyers foun d to be of high quality are given tenured positions and the rest leav e. The value of legal claims handled by a firm determines its sorting problem, which in turn determines its promotion ladder and turnover. Copyright 1987 by University of Chicago Press.
