The labour supply curve shows how changes in real wage rates might affect the number of hours worked by employees.. In economics, a backward-bending supply curve of labour, or backward-bending labour supply curve, is a graphical device showing a situation in which as real (inflation-corrected) wages increase beyond a certain level, people will substitute time previously devoted for paid work ...
However, also as the real wage rate rises, workers earn a higher income for a given number of hours. If leisure is a normal good—the demand for it increases as income increases—this increase in income tends to make workers supply less labour so they can "spend" the higher income on leisure (the "income effect"). If the substitution effect ...
The pure income effect is shown as the movement from point A to point C in the next diagram. Consumption increases from Y A to Y C and – since the diagram assumes that leisure is a normal good – leisure time increases from X A to X C. (Employment time decreases by the same amount as leisure increases.)
The growth rate of the labor force is the time derivative of the labor force divided by the labor force itself. And sometimes there appears a time derivative of a variable which, unlike the examples above, is not measured in units of currency: The time derivative of a key interest rate can appear.
Okun's law is an empirical relationship. In Okun's original statement of his law, a 2% increase in output corresponds to a 1% decline in the rate of cyclical unemployment; a 0.5% increase in labor force participation; a 0.5% increase in hours worked per employee; and a 1% increase in output per hours worked (labor productivity).
In this case, the net effect leads the wife to enter the labor market, thereby increasing the labor supply. An example of the effect can be found in a study by Arnold Katz, who attributes the bulk of the increase in married female workers in the depression of 1958 “to the distress[ed] job seeking of wives whose husbands were out of work ...
The magnitude of the Frisch elasticity is typically between 0 and 1, indicating that the increase in labor supply is less than proportional to the increase in wages. For example, if the Frisch elasticity is 0.5, a 10% increase in wages would lead to a 5% increase in labor supply.
The average product of labor (APL) is the total product of labor divided by the number of units of labor employed, or Q/L. [2] The average product of labor is a common measure of labor productivity. [4] [5] The AP L curve is shaped like an inverted “u”. At low production levels the AP L tends to increase as
