Market Polarization and the Phillips Curve

چکیده
The Phillips curve has flattened out over the last decades. We develop a model that rationalizes this phenomenon as result of observed increase in polarization many industries, process along which few top firms gain an increasing share their industry market. In model, compete la Bertrand and there is exit endogenous market entry, well optimal up downgrading technology. Firms with larger shares find to dampen response price changes, thus cushioning shocks marginal costs through countercyclical markups. Thus, regardless its causes (technology, competition, barriers etc.), recent industries emerges key factor explaining muted responses inflation movements output gap witnessed recently.

This result is at variance with an application of the original Phillips curve to regional data, which would predict that the change in wages ought to be related to the unemployment rate. On the other hand, there is considerable empirical support for the expectations-aug...
متن کاملSectoral Phillips curves and the aggregate Phillips curve
Sector-level Phillips curves are estimated in French data. There is considerable heterogeneity across sectors, with vastly different estimates of the backward looking component of inflation and the duration of nominal rigidities. A multi-sector model of inflation dynamics is calibrated on the basis of these sectoral estimates. Aggregate inflation, simulated on the basis of heterogeneous sectors...
