a.supply is said to be elastic.
b.supply is said to be inelastic.
c.an increase in price will not shift the supply curve very much.

b.(i) and (iii) only
c.(ii) and (iii) only
d.(i), (ii), and (iii)

b.in some occupations, physical attractiveness of workers may enhance the value of

c.beauty acts as an implicit signal of innate intelligence.
d.beautiful people are likely to reflect "good breeding."

b.sales people more as a compensating differential.
c.same salary for both positions because they require the same skill level.
d.same salary for both positions because it would be illegal to do otherwise.

a.under all circumstances.
