Price Competition in an Inflationary Environment

Peter Duersch, University of Heidelberg and Thomas Eife, University of Heidelberg discuss Price Competition in an Inflationary Environment.

ABSTRACT: We study how inflation and deflation affect firms' ability to cooperate in an experimental Bertrand duopoly with differentiated products. We find that there is significantly less cooperation in the treatments with inflation and deflation compared to the no-inflation treatments. The difficulties to cooperate affect prices and welfare: Depending on the market structure, inflation and deflation lead to significantly lower (real) prices and higher welfare.
