The short-run Phillips curve of the current spanish economy

Some economists have advocated an expansionary demand policy to reduce unemployment in Spain. This means accepting a negatively sloped short-run Phillips curve that would allow the exploitation of the celebratred trade-off between inflation and unemployment. This paper gives a qualitative characterization of the Spanish short-run Phillips curve. We argue that this curve is currently vertical and the apparent trade-off shown by the data is misleading, as it is caused by an increase in the equilibrium rate of unemployment. Consequently, the effects of an expansionary demand policy would mainly go into prices and the reduction of unemployment would be small.
