We provide estimates of the shapes of overtime premium schedules for t
hree contrasting economies, based on two-digit industries through time
. At one end of the spectrum, the United Kingdom has no legislation co
ncerning the minimum premium rate while, at the other, the United Stat
es mandates a high minimum premium of 1.5 times the straight-time hour
ly rate. In between these extremes, Japan sets a minimum premium of 1.
25. We concentrate, in particular, on the question of whether the prem
ium rises in average hours.
