Title: Switching Costs in Infinitely Repeated Games

Abstract: We show that small switching costs can have surprisingly dramatic effects in infinitely
repeated games if these costs are large relative to payoffs in a single period. This shows
that the results in Lipman and Wang [2000] do have analogs in the case of infinitely
repeated games. We also discuss whether the results here or those in Lipman–Wang
[2000] imply a discontinuity in the equilibrium outcome correspondence with respect to
small switching costs. We conclude that there is not a discontinuity with respect to
switching costs but that the switching costs do create a discontinuity with respect to the
length of a period.
