1. If a coal-powered electrical generator discharges smoke into the air and causes uncompensated costs and discomfort to residents of a town, then this electrical generation has a(n):
negative externality
positive externality.
specific tax.
quasi-public good.
2. The licenses that are exchanged and that enable the holder to pollute up to a specified amount during a given period are called (from our class discussion about pollution):
tradable emissions permits.
environmental standards.
emissions taxes.
Pigouvian taxes.
3. A _____ in a person’s income will _____ consumer purchasing power, leading to a(n) _____ in consumption of _____ goods.
fall; decrease; decrease; inferior
rise; increase; decrease; normal
fall; decrease; increase; inferior
rise; increase; increase; inferior
4. According the law of diminishing returns:
The total product falls as more units of a variable factor are added to a fixed factor
The marginal product of a variable factor eventually falls as more units of it are added to a fixed factor
Marginal product falls as more units of an input is used
The marginal product eventually increases as more units of a variable factor are added to a fixed factor
5. Suppose a firm's short-run production function is given by Q = 26L0.026 "What is the marginal product of the fourth worker?"
0.231
0.171
0.201
0.141
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.
