Answer:

His income elasticity of demand is 0.16  which means that DVDs are a(n) normal income elasticity of demand as it is less than 1

Explanation:

In this question, we use the formula of income elasticity of demand which is shown below:

Income elasticity of demand = Percentage change in quantity demanded ÷ Percentage change in income

where,

Percentage change in quantity demanded is calculated by

= New Quantity - Old quantity ÷ New Quantity + Old quantity

= 14 - 12 ÷ 14 + 12

= 2 ÷ 26

= 0.07692

Percentage change in income is calculated by

= New income - Old income ÷ New income + Old income

= $43,000 - $40,000 ÷ $43,000 + $40,000

= $3,000 ÷ 63,000

= 0.47619

Now put these values over the above formula

So, the answer is = 0.07692 ÷ 0.47619 = 0.16

Hence, his income elasticity of demand is 0.16  which means that DVDs are a(n) normal income elasticity of demand as it is less than 1

aniked [119]

Answer:

small; standardized; little or no

Explanation:

A perfect competition is when there are many firms in an industry selling standardised or identical goods and services. It is characterised by many buyers and sellers . Sellers have small market share because of the large number of sellers in the market. Prices are usually set by market forces. Sellers cannot influence the price their products sell for , therefore, they are price takers.

There is little or no need for advertising as all firms sell identical goods.

matrenka [14]

aleksklad [387]

Answer:

Answer for the question:

There are ten polluting firms, Firm1,. . . ,Firm10. Each firm emits 100 pounds of pollution prior to any regulations (so there are currently 1,000 pounds being emitted). Each firm has constant marginal abatement costs, but the costs vary across firms. Conveniently, the firms’ names indicate their marginal abatement costs. Firm1’s marginal abatement costs are constant at $1 per pound, Firm2’s marginal abatement costs are constant at $2 per pound,. . . , and Firm10’s marginal abatement costs are $10 per pound.

a. Suppose the regulator wants to achieve a 25% reduction in pollution (250 pounds). What is the cost effective allocation of emis- sions across the ten firms?

b. What are the total abatement costs for society to achieve a 250 pound reduction in emissions?

c. The marginal damage of pollution in this city is given by MD= 4-1/250 X, where X is the total reduction in pollution. What is the optimal level of pollution?

is given in the attachment.
