Which utility function for the representative consumer best describes a​ one-period model in which government spending is not​ wasteful?

A.

U(C,L)=ln(C+0.2•G) +ln(L)

B.

There is no such utility function. In the​ one-period model government spending is always wasteful.

C.

U(C,L)=ln(C) + 0.5•L

Answer #1

(A) is the answer.

Let's take B first: G is spending by govt. for the general public, it is not an investment that will come in the future with a return. G is spent on the public to provide a public good in the current year only. Thus, 'B' is wrong. G is not always wasteful.

(C) In this type of utility function, the general public does not gain any utility from G so adding G will decrease L only. Thus, in this case, G is wasteful. L is a loanable fund most probably.

(A) In this type of utility function, G is explicitly there. Public benefits from G also. As it is in log function so G will add more utility only. Thus, G is not wasteful here.

Suppose the representative consumer’s preferences are given by the utility function, U(C, l) = aln C + (1- a) ln l Where C is consumption and l is leisure, with a utility function that is increasing both the arguments and strictly quiescence, and twice differentiable.

1. Consider the representative consumer’s problem as follows. The representative consumer maximizes utility by choosing the amount of consumption good C and the amount of leisure l . The consumer has h units of time available for leisure l and for working Ns , that is, h = l+Ns . Government imposes a proportional tax on the consumer’s wage income. The consumer’s after-tax wage income is then (1−t )w(h −l ), where 0 < t < 1 is the tax...

Which of the following best describes the assumption on which indifference theory is based? Select one: A. Consumers can always say which of two consumption bundles they prefer without having to say by how much they prefer it. B. The consumer receives the same utility and is therefore indifferent between any two consumption bundles. C. Consumers are not able to rank consumption bundles in order of preference. D. The consumer is able to quantify the difference in total utility received...

A representative consumer living in a Country A values consuming goods (C) and enjoys leisure (l). The consumer has h = 1 units of time to divide between working and enjoying leisure. For each hour worked, he receives w = 1.5 units of the consumption good. The consumer also owns shares in a factory which gives him an additional π = 0.55 units of income. The government in this economy taxes the consumer and uses the proceeds to buy consumption...

Assume the representative consumer lives in two periods and his preferences can be described by the utility function U(c,c′)=c1/3 +β(c′)1/3, where c is the current consumption, c′ is next period consumption, and β = 0.95. Let’s assume that the consumer can borrow or lend at the interest rate r = 10%. The consumer receives an income y = 100 in the current period and y′ = 110 in the next period. The government wants to spend G = 30 in...

Which of the following best describes the multiplier process? A. A decrease in investment spending leads to a decrease in disposable income, which causes consumers to reduce their spending. B. A decline in net exports leads firms to reduce their investment spending, which raises interest rates and causes further reductions in investment spending. C. A decrease in exports leads to a reduction in taxes, which causes government spending to fall. D. An increase in interest rates leads firms to cut...
