b
A decrease in supply will cause the largest increase in price when
both supply and demand are inelastic.
A good will have a more inelastic demand, the
broader the definition of the market

d
Refer to Figure above. When trade in coffee is allowed, consumer surplus in Uganda
decreases by the area B + F

domestic sellers become better off and domestic buyers become worse off

fall by 50 percent
Elasticity of demand is closely related to the slope of the demand curve. The more responsive buyers are to a change in price, the
flatter the demand curve will be.

increase by 16.80 percent.

increase total revenue of donuts sellers.
When an externality is present, the market equilibrium is
inefficient, and the equilibrium does not maximize the total benefit to society as a whole.
When large changes in price lead to no changes in quantity demanded, demand is perfectly
inelastic, and the demand curve will be vertical.
The infant-industry argument
is based on the belief that protecting industries when they are young will pay off later.
Most economists prefer corrective taxes to regulation as a way to correct the problem of pollution because the market-based solution
is less costly to society.

producer surplus decreases and total surplus decreases in the market for that good.

property rights are clearly defined.

social benefits will be greater than private benefits.
If the cross-price elasticity of two goods is positive, then the two goods are
substitutes.

tends to be elastic.
