Assume an economy with 1000 consumers. Each consumer has income in the current period of 50 units and future income of 60 units and pays a lump-sum tax of 10 in the current period and 20 units in the future period. The market real interest rate is 8%. Of the 1000 consumers, 500 consume 60 units in the future, while 500 consume 20 units in the future.

a) Determine each consumer’s current consumption and current saving

Solutions

Expert Solution

There are two types of people, first type who consume 60 units in future and second type who consumes 20 units in the future. There are 500 consumers of type 1 and 500 consumers of type 2.

Determine each consumer’s current consumption and current savings.
Income is 50 units now, 60 units later.
Taxes are 10 units now, 20 units later. (note;
Income - Taxes = Disposable Income.
Disposable income is 40 units now, 40 units later.

Type 1.
Future consumption: 60 units.


Total consumption = current consumption + future consumption
(50-10) + (60-20) = current consumption + 60
80 = current consumption + 60
Current consumption = 20
Current savings = (50-10) - 20 = 20

Type 2.
Future consumption: 20 units.


Total consumption = current consumption + future consumption
(50-10) + (60-20) = current consumption + 20
80 = current consumption + 20
Current consumption = 60
Current savings = (50-10) - 60 = -20

Assume a consumer who has current-period income y=200, future period income y’=150, current taxes t = 40, and future taxes t’= 50, and faces a market interest rate of r=5 percent or .05. The consumer would like to consume such that c’=c*(1+r) if possible. However, this consumer is faced with a credit market imperfection, in that no borrowing is allowed. That is s must be greater or equal to zero.   a. Show the consumer’s lifetime budget constraint and indifference curves...

1. Consider the Solow growth model. In the current period there are N = 1000 consumers and the population grows annually at a rate of 2%. The production function is given by Y = zK^(α)N^(1−α) where α = 0.4 and z = 1.1. The depreciation rate is δ = 0 and the savings rate is s = 0.2. a. Find steady-state output and consumption per capita in the current period. b. Find aggregate output, aggregate consumption and aggregate capital in...

Tax on labor income - Consider a one-period economy where the representative consumer has a utility function u(C;L) over consumption C and leisure L. Assume preferences satisfy the standard properties we assumed in class. The consumer has an endowment of one unit of time. She earns the wage w per unit of labor supplied to the market and has wealth A which yields an interest rate r, so her income is partly coming from labor, partly from capital. Suppose that...

Consider a two-period model in which the consumer receives income of y in the current period and y' in the future period. Rather than imposing lump-sum taxes, the government imposes a proportional tax on consumption. In the current period the tax rate is σ and in the future period the tax rate is σ'. As a result, the government collects σc in goods in the current period and σ'c' in goods in the future period. Since G and G' are...

Fact I: A consumer receives income y in the current period, income y’ in the future period, and pays taxes of t and t’ in the current and future periods, respectively. The consumer can lend at the real interest rate r. The consumer can borrow at the interest rate r but can only borrow an amount h or less, where h < we - y + t, with "we" denoting lifetime wealth. Clearly illustrate in a graph what happens to...

Assume that a consumer lives for T periods, and in each future period, one of the s states may be realized. There are complete markets. Let the utility function of the agent be U = u(c1) + T X t=2X s∈S βt−1πt,su(ct,s) where the notation is the same as that used in class, with pt,s, denoting the price of Arrow-Debreu security paying off at state s on date t. a. What do complete markets mean in this context? b. Write...

In an exchange economy with two consumers and two goods, consumer A has utility function U! (xA,yA) = xA*yA, consumer B has utility function U! (xB,yB) = xB*yB. Let (x ̄A,y ̄A) represent the endowment allocation of consumer A and (x ̄B,y ̄B) represent the endowment allocation of consumer B. The total endowment of each good is 20 units. That is, x ̄A + x ̄B = 20 and y ̄A + y ̄B = 20. Set y as a...

Assume the government has a balanced budget and that the economy is experiencing a period of growth higher than predicted, tax receipts (collected) by the government are likely to A) increase and result in a budget deficit. B) decrease and result in a budget deficit. C) increase and result in a budget surplus. In 2016, the federal government spent $200 billion but collected $180 billion in taxes, therefore in 2016, the government accumulated A) a budget surplus of $20 billion....

A consumer’s income in the current period is y =100, and income in the future period is y’=120. He or she pays lump-sum taxes t = 20 in the current period and t’=10 in the future period. The real interest rate is 0.1, or 10% per period. a) Determine the consumer’s lifetime wealth. b) Suppose that current and future consumption are perfect compliments for the consumer and that he or she always wants to have equal consumption in the current...
