What was Cindy's saving during the summer and the change, if any, in her wealth? >>> If your answer is negative, include a minus sign. If your answer is positive, do not include a plus sign. Cindy's saving during the summer is S[

Scenario 1: Individual Retirement Accounts (IRAs) allow workers to shelter a portion of their income from taxation. Suppose the maximum annual contribution to accounts of this type is $6,000 per person. Now suppose there is an increase in the maximum contribution, from $6,000 to $9,000 per year. Shift the appropriate curve on the graph to reflect this change. This change in the tax treatment of saving causes the equilibrium interest rate in the market for loanable funds tofall   and the level of investment spending toincrease   .   Scenario 2: An investment tax credit effectively lowers the tax bill of any firm that purchases new capital within some relevant time period. Suppose the government implements a new investment tax credit. Shift the appropriate curve on the graph to reflect this change. The implementation of the new tax credit causes the interest rate tofall   and the level of saving tofall   .   Scenario 3: Initially, the government's budget is balanced; then…

Suppose that y =100 (income today) • y' = 150 (income tomorrow) 10% (interest rate on bonds) %3D r = • t = 10 (taxes today) • t' = 10 (taxes tomorrow) Suppose that c = 100. Is the consumer borrowing or saving, today? And what will her budget constraint look tomorrow? The consumer is borrowing. Her budget constraint tomorrow will be c' = 150 -10 - 10*(1.1) = 129 The consumer is saving. Her budget constraint tomorrow will be c' = 150 -10 + 10*(1.1) = 151 O The consumer is neither borrowing nor saving - she is breaking even. Her budget constraint tomorrow will be c' = 150 -10 = 140 O The consumer is saving. Her budget constraint tomorrow will be c' = 150 + 10*(1.1) = 161 %D

Suppose you bought a condo for $100,000 financing it with a $20,000 down payment of your own funds and an $80,000 mortgage loan from a bank.          Now, instead of (a) or (b), suppose the value of the condo fell from $100,000 to $70,000.  Assuming you paid $100,000, financing it with $20,000 of your own money and $80,000 with a mortgage loan, and ignoring interest and other costs, calculate your rate of return on your asset (ROA) and your rate of return on equity (ROE).  What is the value of your equity stake in the condo after the price fall?

U(C1, C2) = c₁0.8 20.4 where c₁ is the quantity of current consumption goods and c₂ is the quantity of future consumption goods. Consider a consumer whose income is y₁ = 100 in the current period and y₂ = 140 in the future period. The consumer pays lump-sum taxes t₁ and t₂ == = 20 in the current period 10 in the future period. The real interest rate is r = 0.1, or 10%, per period. (a) Write down the consumer's budget constraint for each period and derive the consumer's lifetime budget constraint. What is the value of the consumer's lifetime wealth? [Note: Lifetime wealth is the present value of the consumer's lifetime disposable income] (b) Draw the lifetime budget line on the (C1, C2) plane with c₁ on the horizontal axis and C₂ on the vertical axis. Include the values of the intercepts and the endowment point in your graph. What is the slope of the budget line? (c) What are the two conditions that the consumer's optimal choice of (C1, C2) must satisfy? Find the consumer's optimal…

Harper is a short-lived human who only lives for two years: current year and next year. In the current year, Harper has an income of $189 and has to pay $36 in taxes. Harper expects that he can receive an income of $132 and has to pay $27 in taxes next year before he dies. The real interest rate between current and next year is 7%.  What is Harper's lifetime wealth (in $)? Round your answer to at least 2 decimal places

Mr. Smith has some money to invest. He selected three stocks and two bond funds as possible investments, shown in the following table. Investment Stock A Stock B Stock C Bond-long term Bond-short term Risk Annual Return High Medium Low 15% 12% 9% 11% 8% One of Mr. Smith's investment requirements is "the total amount invested cannot exceed $500,000". Which option represents this constraint? Note: (X₁, X₂, X₁, X₁, and X, are investment in stock A, stock B, stock C, long term bond and short term bond, respectively

Dell Computer makes its suppliers wait 37 days on average to be paid for their goods; however, Dell is paid by its customers immediately. Thus, Dell earns interest on this float, the money that it is implicitly borrowing. If Dell can earn an annual interest rate of 4%, what is this float worth to Dell per dollar spent on inputs?

Suppose Poornima is an avid reader and buys only comic books. Poornima deposits $3,000 in a bank account that pays an annual nominal interest rate of 10%. Assume this interest rate is fixed-that is, it won't change over time. At the time of her deposit, a comic book is priced at $15.00. Initially, the purchasing power of Poornima's $3,000 deposit is comic books. For each of the annual inflation rates given in the following table, first determine the new price of a comic book, assuming it rises at the rate of inflation. Then enter the corresponding purchasing power of Poornima's deposit after one year in the first row of the table for each inflation rate. Finally, enter the value for the real interest rate at each of the given inflation rates. Hint: Round your answers in the first row down to the nearest comic book. For example, if you find that the deposit will cover 20.7 comic books, you would round the purchasing power down to 20 comic books under the assumption that Poornima will…

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 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. b) Determine aggregate private saving, aggregate consumption in each period, government spending in the current and future periods, the current-period government deficit, of the quantity of debt issued by the government in the current period. c) Suppose that current taxes increase to 15 for each consumer. Repeat parts (a) and (b) and explain your results.
