The threat of "currency wars": A European perspective

The ‘currency war’, as it has become known, has three aspects: 1) the inflexible pegs of undervalued currencies; 2) recent attempts by floating exchange-rate countries to resist currency appreciation; 3) quantitative easing. Europe should primarily be concerned about the first issue, which relates to the renewed debate about the international monetary system. The attempts of floating exchange-rate countries to resist currency appreciation are generally justified while China retains a peg. Quantitative easing cannot be deemed a ‘beggar-thy-neighbour’ policy as long as the Fed’s policy is geared towards price stability. Current US inflationary expectations are at historically low levels. Central banks should come to an agreement about the definition of price stability at a time of deflationary pressures. The euro’s exchange rate has not been greatly impacted by the recent currency war; the euro continues to be overvalued, but less than before.

Nothing so certain as your anchors? A consumer bias that might lower prices

Anchoring is a well-known decision-making bias: original guesses for a certain question could act as anchors and could influence our final answers. Reference prices - in a similar fashion - can lead to a bias in consumer valuations, and thus consumer demand will be coherent but not one derived from a utility framework. In our paper we investigate the effect of the existence of anchoring on how oligopolistic firms might change their pricing strategy. More specifically, we analyze the effect of anchoring on pricing when differentiated firms compete in Bertrand fashion. We show that if the anchoring effect is smaller than a threshold the average price is lower compared to the no-anchoring case.
