Determinants of Firm Internal Labor Markets in Large Law Firms
研究发现，在大型律师事务所中，晋升比外部招聘更常见，四分之三的合伙人职位来自内部晋升；律所增长、大客户数量及新增大客户会促进晋升，而前期晋升会减少当前晋升。
Douglas R. Wholey Professional labor markets, such as law, are often thought to be highly open occupational internal labor markets, in which promotion is rare and lateral entry is common. In the law firms analyzed in this study, however, promotion was much more common than lateral entry: three out of four partnership positions in law firms were staffed through promotion rather than lateral entry. Law firm growth, the number of major clients, and addition of major clients increased promotion, while promotions in prior periods decreased current promotion. Addition of major clients and promotions in prior periods led to lateral entry.
