The Calvo contract Phillips Curve is widely indexed for general inflation, using either core inflation or other backward-looking formulae. Such a Phillips Curve implies a high and persistent degree of nominal rigidity. It is argued here that optimal indexation would by contrast use the rational...

The short- and longer-term regional consequences of migration for European aggregate supply are examined in a simple model in which human capital enters the production function externally. The planner chooses a reallocation of population across East and West that cannot be replicated by the...

We analyse how globalization forces induce monetary authorities, guided in their policies by the welfare criterion of a representative household, to put greater emphasis on reducing the inflation rate than on narrowing the output gaps. Specifically, I demonstrate how the relative weight of the...

We compare monetary union to flexible exchange rates in an asymmetric, three-country model with active monetary policy. Unlike Friedman's (1953) case for flexible rates, we find that countries with high degree of nominal wage rigidity are better off in a monetary union. Their benefits increase...

Assuming that economic reforms are successful in Eastern Europe, what will be the effects on Western Europe? The focus is on the wage pressure that the threat of migration from East to West is likely to impose. The paper adopts a Ramsey model of intertemporal choice, for both individuals and...

We develop and analyse a structural model of efficiency wages founded on reciprocity. Workers are assumed to face an explicit trade-off between the disutility of providing effort and the psychological benefit of reciprocating the gift of a wage offer above some reference level. The model...

Implicit contract theory has been successful in explaining wage rigidity but not unemployment. We argue that the theory has paid insufficient attention to (i) the general equilibrium aspects and (ii) constraints limiting the set of feasible contracts. Implicit, as opposed to explicit contracts,...

We incorporate reference-dependent preferences into a search-and-matching model of the labor market, in which firms have all the bargaining power and productivity follows an AR(1) process. Motivated by Akerlof (1982) and Bewley (1999), we assume that existing workers are willing to exert unobserved,

Recent research in macroeconomics emphasizes the role of wage rigidity in accounting for the volatility of unemployment fluctuations. We use worker-level data from the CPS to measure the sensitivity of wages of newly hired workers to changes in aggregate labor market conditions. The wage of new...

The great contraction of 2008 pushed the U.S. economy into a protracted liquidity trap (i.e., a long period with zero nominal interest rates and inflationary expectations below target). In addition, the recovery was jobless (i.e., output growth recovered but unemployment lingered). This paper...
