In the empirical literature on assortative matching using linked employer-employee data, unobserved worker quality appears to be "negatively" correlated with unobserved firm quality. We show that this can be caused by standard estimation error. We develop formulae that show that the estimated...

This article is an example of the type of exercise that is made possible by the existence of the set of UK models at Warwick. Using three quarterly models, those of the London Business School (LBS), the National Institute of Economic and Social Research (NIESR) and Her Majesty's Treasury (HMT),...

Recent policy debate in Europe suggests that a shorter workweek will lead to more jobs (worksharing). We derive and estimate a model where the firm employs two types of workers, some working overtime, the rest standard hours. Worksharing is not always a prediction of the theory. Using German...

This paper provides the first estimates of the determinants of the duration of employer search in the UK. We model duration until a vacancy is either successfully filled or withdrawn from the market. The econometric techniques deal with multiple vacancies and unobserved heterogeneity (dependent...
