Resumen de Cartels and regulation: effects on prices and real sales in sweden (1976–1990)

Aitor Ciarreta Antuñano

• We estimate the effects of competition and regulatory policies on prices and real sales in Sweden during the period 1976–1990. We find evidence supporting the hypothesis that prices were higher on average in those markets affected by horizontal collusion, and therefore lower real sales. Market concentration and lower foreign trade are significantly associated with higher prices. We also observe how prices (output) tend to rise (fall) around cartel formations and fall (rise) around cartel termination as theories of cartels suggest.
