It is known that the effectiveness of macro policies depends on the exchange-rate regime. Pertinent models have typically considered either fixed or floating rates rather than mixed regimes. In recent years, however, the dollar has floated against most currencies, while being fixed against the yuan. This paper argues that a flex-price, dual-rate model consisting of the U.S., China and the Eurozone, combined with distinct adjustment patterns in tradables and non-tradables sectors and a tendency for policy makers to treat inflation in housing as pure asset inflation, provides a plausible explanation of the great moderation and its aftermath.
