This paper presents preliminary findings of a study of worker absenteeism. Our main purpose is to identify the various factors that influence the rate of absence for individual workers and to quantify their impact. Candidates for inclusion are measurable factors relating either to the structure...

Using the personnel records of a large British financial sector employer we investigate how workers respond to remuneration differences and "luck" in the promotion system. The results confirm that workers respond to larger remuneration spreads by working harder. Increased certainty in the...

Several tests for heteroskedasticity in linear regression models are examined. Asymptoticrobustness to heterokurticity, nonnormality and skewness is discussed. The finite sample eliability of asymptotically valid tests is investigated using Monte Carlo experiments. It is found that asymptotic...
