Selection Effects with Heterogeneous Firms

  • Peter Neary
  • Monika Mrazova

We provide a general characterization of which firms will select alternative ways of serving a market.� If and only if firms' maximum profits are supermodular in production and market-access costs, more efficient firms will select into the activity with lower market-access costs.� Our result applies in a range of models and under a variety of assumptions about market structure.� We show that supermodularity holds in many cases but not in all.� Exceptions include FDI (both horizontal and vertical) when demands are "sub-convex" (i.e., less convex than CES), fixed costs that vary with access mode, and R&D with threshold effects.
