What is an equilibrium generated by replication? Sorry this might be a little too rudimentary for you, but I'm not an Econ background. When I was doing exercises for MGW chapter 17 "Positive Existence of Equilibrium" I came across the following statement 


  The consumers preferences are strictly convex, this implies that there is no equilibrium in the overall economy generated by replication.


What doe equilibrium generated by replication mean? I couldn't find it in the text. 

Thanks in advance.
For each agent in the economy, create n agents with the same endowment and preferences. The result is the replication economy. Sometimes n is taken to infinity in proofs. 
Chapter 17.I in Mas-Colell explains in detail. Related material is the regularizing effects of aggregation, appendix of Chapter 4.
