Data on the life-cycle profiles of inequality in wages, earnings, hours worked and consumption contains precious information for answering questions about the ability of households to insure labor market risk and about the sources of this risk. This paper demonstrates that the choice of whether to control for cohort effects or for time effects has a drastic impact on the estimated age profiles ...

Purified rat liver microsomal cytochrome P-450 and NADPH-cytochrome P-450 reductase were co-reconstituted in phosphatidylcholine-phosphatidylethanolamine-phosphatidylserine vesicles using a cholate dialysis technique. The co-reconstitution of the enzymes was demonstrated in proteoliposomes fractionated by centrifugation in a glycerol gradient. The proteoliposomes catalyzed the N-demethylation o...

One Man’s Blessing, Another Woman’s Curse? Family Factors and the Gender-Earnings Gap of Doctors * Using data from a new longitudinal survey of doctors from Australia, the authors test whether observed large gender-pay gaps among general practitioners (GPs) are the result of women's larger willingness to interrupt their careers. On average, female GPs earn A$83,000 or 54% less than male GPs. Th...

We evaluate the e¤ects of aging on productivity using data from piece-rates. Our data contains the population of Finnish blue collar metal industry workers from years 1996-2000. A unique feature of the data is that we can observe the exact hours worked on piece-rates and time rates as well as earnings from both performance schemes. Moreover, a subset of workers receive both piece-rates and time...

Estimates of a Labour Supply Function Using Alternative Measures of Hours of Work Depending on data source, estimates of hours of work give widely different results both as to level and change. In this paper three alternative measures of hours worked are used to estimate a simple labour supply function to investigate if estimated wage rate and income effects are data dependent as well. The meas...

In this paper, I present evidence that the premium for a college education is essentially uncorrelated with the business cycle and that the average hours worked by college graduates are less volatile than those worked by nongraduates. Business cycle theory is then shown to be inconsistent with these observations when endogenous utilization and skill acquisition are incorporated. Abstracting fro...

As Europe ages, the proportion of people who work will decline unless older individuals remain in the labor force. Such reform could be part of a more general redistribution of work. If a greater share of the population worked, then the average number of hours worked per week could be reduced. This could particularly help younger people and increase Europe's low birth rates. The challenges faci...

In a study of 142 Japanese men from a cross-section of the workforce of a technology development company, we found that the percentage of CD56+ cells was inversely correlated with the number of hours worked per week. A low CD56+ cell percentage was associated with longer weekly working hours and shorter daily sleeping hours.

The method of investigation consisted in submitting a preparation of urease to the action of a dyestuff at PHI 7-4 and at 450 for a given time, usually 30 mins. or 1 hour, and in then determining the activity of the enzyme by estimating the amount of ammonia produced at 450 in a given time from a 0 3 % solution of urea. 1 cc. of the enzyme preparation was added to 2 cc. M/15 phosphate buffer so...
