DESCRIPTION:In the last few years\, there have been a growing number of stu
 dies pointing to a decline in the labor share\, and this new fact has been 
 clearly confirmed by Autor et al. and Karabarbounis and Neiman\, among othe
 rs. One of their key findings is that the decline in the labor share is pri
 marily driven by reallocation among firms\, rather than the decline in the 
 weighted average labor share within firms (between-firm effect). On the oth
 er hand\, at the industry level\, the aggregate macro labor share is mainly
  affected by within-industry effects (the movement of the labor share in ea
 ch industry). To explain these facts simultaneously\, Autor et al. propose 
 the “superstar” firm theory. That is\, the aggregate labor share of an 
 industry tends to decline as the most productive firms with the lowest labo
 r share\, called “superstar” firms\, increasingly dominate the industry
 . Their theory is analyzed completely within the framework of statics\, eve
 n though it clearly has many dynamical aspects. In this study\, we propose 
 a multiple-firm optimal growth model as a benchmark model that provides a s
 olid theoretical foundation for the superstar firm theory. The multi-firm o
 ptimal growth model was intensively investigated by J. Scheinkman and L. Mc
 Kenzie\, under the title "Turnpike theory for multisector optimal growth mo
 del." The focus here is on the dynamic theory of superstar firms\, but as t
 he causes of the declining labor income share are as diverse as those repor
 ted in the McKinsey Discussion Paper\, the policies that address them must 
 also be diverse.\\n\\nContact: Ewen Gallic : ewen.gallic[at]univ-amu.frAvne
