Document Summary

= pq + p(dq) + (dp)q + q p p q. = old price + change in price)(old quantity +change in quantity) - pq. Quantity effect: gain in revenue because quantity increases. Gain in revenue because quantity increases - loss in revenue from price reduction. Delta r: (new revenue - original revenue) dr = dq + dp + dp*dq. Elasticity of demand is negative because demand is sloping downward. When quantity increases along the demand curve price is dripping. Usually use midpoint formula: average of the two. Two possibilities either the absolute value of the quantity effect is greater than the absolute value of the change in price . That means that elasticity of demand is less than -1 which means that the demand is eleastic. When absolute value of change in quantity/ quantity is less than the absolute value of price /p than 0 > ed > 1 demand is inelastic.

1. Suppose that a 10% increase in the wage results in a 5% reduction in employment. In this case, labor demand is said to be:

A. elastic

B. inelastic

C. unit elastic

2. Which of the following best explains why elasticity varies along a linear demand curve?

A. As the quantity of labor demanded rises, the percentage change in quantity demanded declines (for a given change in labor use) while the percentage change in wage increases.

B. As the quantity of labor demanded rises, the percentage change in quantity demanded rises (for a given change in labor use) as does the percentage change in the wage.

C. As the quantity of labor demanded rises, the percentage change in quantity demanded declines (for a given change in labor use) as does the percentage change in the wage.

D. As the quantity of labor demanded rises, the percentage change in quantity demanded declines (for a given change in labor use) while the percentage change in wage decreases

3. Labor demand is more elastic when:

A. the substitution effect resulting from a wage change is larger

B. the scale effect resulting from a wage change is larger

C. both are correct

D. none of the above

4. The scale effect associated with a change in the wage is larger when:

A. the demand for the final product is more elastic

B. labor costs are a smaller share of total costs

C. there are many close substitutes for this category of labor

D. economics of scale are present in the production of the good

5. The price elasticity of demand for the final products affects the own-wage elasticity of demand for labor by affecting the magnitude of:

A. the substitution effect that occurs in the labor market

B. the scale effect that occurs in the labor market

C. both substitution and scale effects

D. neither substitution nor scale effects

6. Unions are expected to attempt to:

A. make it more difficult to replace labor with other resources

B. reduce the elasticity of demand for the final product

C. support laws that reduce the elasticity of supply of other resources

D. all of the above.

E. none of the above

7. Unions are likely to be less successful in negotiating higher wages in those labor markets in which:

A. the demand for the final product is more elastic

B. there are few close substitutes for union workers

C. the price elasticity of supply for other factors of production is relatively high

D. labor costs comprise a small share of total costs

b. the slope of the demand curve for labour

c. the percentage change in the price of labour divided by the percentage change in the supply of labour

d. the per cent change in the quantity demanded of labour divided by the percentage change in the price of labour
