(a)

Explanation of Solution
The components of the aggregate demand are the consumption expenditure, government spending, investment, and net exports. The factors influenced by the change in aggregate demand are the expectation, fiscal and
Aggregate demand: The aggregate demand is the total demand for the goods and services produced by a nation in a given period.
(b)
Identify the impact on aggregate demand when increased fear of inflation.
(b)

Explanation of Solution
Inflation is a situation of continuous rise in the price level of goods and services in the economy. According to the consumers and investors, they would not receive any benefit from the consumption and investment during the period of inflation because of the higher-price level and higher-interest rate. Hence, the consumer and investors increase their spending and investment in the current period. Therefore, the fear of inflation will increase the current aggregate demand.
(c)
Identify the impact on the aggregate demand when the rapid growth of real income.
(c)

Explanation of Solution
The rapid growth of real income from abroad will influence the higher demand for exports. If the real income of Country C and Country W increases, they will demand more goods and services from abroad. Suppose Country U trades with Country C and Country W, and Country C and Country W demand more goods and services, then the export of Country U will increase. Since the net export is one of the components that influence the aggregate demand, an increase in the real income of Country C and Country W will demand more goods and services from Country U, and this will lead to an increase in the net export of Country U. Hence, an increase in export of Country U will increase the current aggregate demand of Country U.
Net export: The net export is the difference between the total export and total import of a nation in a given period.
(d)
Identify the impact on the aggregate demand when there is a reduction in the real interest rate.
(d)

Explanation of Solution
The real interest rate is influenced by the savings and investment in the loanable funds market. Since the interest rate and investment have an inverse relationship, a fall in the real interest rate in the loanable funds market will increase the investment and consumer spending. Since the investment and consumer spending are the components of the aggregate demand, an increase in the investment and consumer spending will increase the current aggregate demand.

It sent out proxies to its stockholders on March 15 and asked stockholders who plan to attend the meeting to respond. To plan for a sufficient number of information packages to be distributed at the meeting, as well as for refreshments to be served, the company has asked you to forecast the number of attending stockholders. By April 15, 378 stockholders have expressed their intention to attend. You have available the following data for the last 6 years for total attendance at the stockholder meeting and the number of positive responses as of April 15: Year Positive Responses Attendance 2007 322 520 2008 301 550 2009 398 570 2010 421 600 2011 357 570 2012 452 650 1.

Are there any other factors that could affect attendance, and thus make your forecast inac- curate?arrow_forwardProblem 4 Office Enterprises (OE) produces a line of metal office file cabinets. The company's economist, having investigated a large number of past data, has established the following equation of demand for these cabinets: Q=10,000+6013-100P+50C Q=Annual number of cabinets sold B = Index of nonresidential construction P = Average price per cabinet charged by OE C=Average price per cabinet charged by OE's closest competitor It is expected that next year's nonresidential construction index will stand at 160, OE's average price will be $40, and the competitor's average price will be $35. 1. Forecast next year's sales. 2. What will be the effect if the competitor lowers its price to 832? If it raises its price to $36? 3. What will happen if OE reacts to the decrease mentioned in part b by lowering its price to $37? 4. If the index forecast was wrong, and it turns out to be only 140 next year, what will be the effect on OE's sales? If not, what does it measure?arrow_forward

In this question, assume all dollar units are real dollars in billions. For example, $100 means $100 billion. Argentina thinks it can find $105 of domestic investment projects with a marginal product of capital (MPK) equal to 10% (each $1 invested in year 0 pays off $0.10 in every later year). Assume a world real interest rate r*is 5%, and initial external wealth W (W in year -1) is 0. a. You find that the formula on the lecture slide: > r*, which means that a country will ΔΟ AK take on investment projects as long as the marginal product of capital (MPK) is at least as high as the real interest rate. Using this formula, answer if Argentina should conduct the project. b. If the projects are not done, GDP = Q = C = $200 in all years. Compute the present value of Q and C. c. If Argentina conducts the projects (investing $105), what is the present value of Q and C? d. If Argentina conducts the projects, what is the present value of C? Is Argentina better off with the investment?arrow_forward2. Consider a world of two countries: Highland (H) and Lowland (L). Each country has an average output of 9 and desires to smooth consumption. All income takes the form of capital income and is fully consumed each period. Initially, there are two states of the world: Pandemic (P) and Flood (F) each occurring with 50% probability. Pandemic affects Highland and lowers the output there to 8, leaving Lowland unaffected with an output of 10. Flood affects Lowland and lowers the output there to 8, leaving Highland unaffected with an output of 10. a. Assume that households in each country own the entire capital stock of their own land.
