13/5/2013: Work Hours, Education Years and Wages


A fascinating fact: "An average person born in the United States in the second half of the 19th century completed 7 years of schooling and spent 58 hours a week working in the market. In contrast, an average person born at the end of the 20th century completed 14 years of schooling and spent 40 hours a week working. In the span of 100 years, completed years of schooling doubled and working hours decreased by 30%."

Restuccia, Diego and Vandenbroucke, Guillaume ask "What explains these trends?"

Their paper (link below) quantitatively assessed "the contribution of exogenous variations in productivity (wage) and life expectancy in accounting for the secular trends in educational attainment and hours of work."

And the result? "We find that the observed increase in wages and life expectancy accounts for 80% of the increase in years of schooling and 88% of the reduction in hours of work. Rising wages alone account for 75% of the increase in schooling and almost all the decrease in hours in the model, whereas rising life expectancy alone accounts for 25% of the increase in schooling and almost none of the decrease in hours of work."

Aside 1: note that higher wages (when aligned with higher productivity) imply higher human capital intensity and lower hours of wrok supplied.

Aside 2: there seem to be no control for the reporting of hours supplied. In mid-19th century and even in first half of 20th century, most of work performed was time-sheeted. Today, majority of us do not have time cards, so on the surface, our contracts say 40 hours per week, in reality this means 60 hours per week.

19/8/2012: Gaffe of the week?

An interesting revelation comes the courtesy of one of our Senators: 

"It's very hard work. You have two-and-a-half to three weeks' work in one week. We start at 8 in the morning and don't finish until 5 or 6. That's a lot more work than a day at home."

In other words, Mrs Fidelma Healy Eames (Senator) has found herself working 2.5-3 times the normal week's work load by taking up work lasting from 8 am through 5-6 pm. Let's do the maths: 10 hours day span for working day is 2.5-3 times normal weekly time implies that 'normal' working hours for Mrs Eames are in the region of at most 10/2.5=4 hours. 

But let's give Mrs Eames some benefit of the doubt and suppose that she worked the horrific hours seven days a week with no lunch or other breaks, in which case her work load on her trip to Rwanda and Kenya was running at (7 days x 9 or 10 hours per day) = 63-70 hours per week. If that is 2.5-3 times the normal work load, our Senator undertakes back at home (in Ireland), her statement suggests working week of 21-28 hours per week in Ireland. 

By the way, average paid working hours in Civil Service and Defence sector in Ireland in Q1 2012 stood at 34.6 hours per week. And that is skewed down by part time workers taking lower hours.
