Abstract
We examine the US wage curve using longitudinal micro data. Results support the wage curve, but are sensitive
to inclusion of regional and/or personal fixed effects. We find that hourly wages are less responsive to local
unemployment than annual earnings.
Keywords: Wage curve; Local unemployment

I. Introduction
In recent contributions to the literature, Blanchflower and Oswald (1990, 1994a,b, 1995)
profess to have uncovered an empirical law of economics- the wage curve. The wage curve
describes a fundamental negative relationship between a worker's pay and the unemployment
rate in the local labor market. This negative association contradicts traditional thinking on the
wage-unemployment relationship, that wages and unemployment should be positively
correlated across regions (Harris and Todaro, 1970; Hall, 1970, 1972). The importance of the
wage curve is emphasized by Card (1995), who states that "[Blanchflower and Oswald may]
have isolated the missing link that has long evaded macro modelers: a relatively elastic
quasi-supply function that can be combined with a simple labor demand function to construct
a model of the aggregate labor market."
The empirical foundation of the wage curve is a Mincerian wage regression augmented with
the unemployment rate in the worker's local labor market. A number of recent studies
document the existence of the wage curve in micro data sets from several countries
(Blanchflower and Oswald, 1995; Card, 1995; Groot et al., 1992; Wagner, 1994). The present
study explores the US wage curve for young workers, drawing on data from the National
