In this paper we use a model of vertical product differentiation to cast doubt on the general validity of the import demand function as specified in macroeconomic models. The empiricai importance of our theoretical concerns is then examined with the aid of two hypotheses. According to the first...

In the time domain, the observed cyclical behavior of the real wage hides a range of economic influences that give rise to cycles of differing lengths and amplitudes. This may serve to produce a distorted picture of wage cyclicality. Here, we employ frequency domain methods that allow us...

Using individual-level data on male non-managerial workers from the 1996 British New Earnings Survey, we estimate overtime hours and average premium pay equations. Among other issues, four broad questions are of central importance. (a) What are the impacts of straight-time pay and hours on...
