Solutions

Expert Solution

1) if a coal powered electrical generator discharges smoke into the air and causes uncompensated cost and discomfort to residents of a town then this electrical generation has a negative externality Because of the negative effects it has.

Hence, first option is correct

2) the licences that are exchanged and that enable the holder to pollute up to a specified amount it during a given period are called tradable emission permits. This permits can be traded in the market for emission permits.

Hence, first option is correct.

3) A fall in a person's income will decrease consumer purchasing power leading to an increase in the consumption of inferior goods.

Hence, third option is correct i.e, fall; Decrease ; Increase; Inferior.

4) according to the law of of diminishing Returns the marginal product of a variable factor eventually falls as more units of it are added to a fixed factor.

Hence, second option is correct.

5) Marginal Product of a Worker= 26(0.026)L​​​​​​–0.974

Marginal Product of Fourth Worker= 26(0.026)(4)–0.974

Marginal product of Fourth Worker= 0.171

Hence, second option is correct.
