Title: A Note on 'Strategic Choices of Flexible Production Technologies and Welfare Implications'
Author(s): Sudheer Gupta
Volume: 46 (3)
Issue: September 1998
Pages: 403
Abstract: This note corrects certain errors in welfare calculations and graphs of a paper by Röller and Tombak [1990]. The corrections necessitate a reinterpretation of some of their results. Contrary to authors' assertion (proposition 1), consumer surplus is not always the highest in (FMS, FMS) state. Producing in both markets imposes a negative externality that grows as products become more substitutable, leading to a reduction in output levels. Secondly, corrected graphs reveal that the difference in producers' and total surplus between (DE, DE) and (FMS, FMS) states is not as large as depicted by the authors.
