(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.

- While visiting and chatting with an old friend who lives in a rural area, a man's teenage daughter joins the conversation and shared that she wants to work on a farm after she graduates from college and that farming is her passion. She shared the graph that follows from the Bureau of Labor Statistics that she recently obtained that shows the average wage (salary) by profession. She was very confused about why different professions pay people different wages. She was expecting the pay rate for people who work in the farming industry to be paid more than other “unnecessary” professions. While sharing the data with you, she asked the following questions: Why do workers in business and financial operations get paid more than those who work in farming and health care? After all, farmers make food and health care workers help people’s health. I don’t get it, but who decides how much people in certain professions get paid? I mean who decides how much I should be compensated for my work?

- 2. Sweet taxes make the world sweeter! According to a study conducted by the World Health Organization, noncommunicable diseases, such as heart disease, cancer, diabetes, chronic lung disease, and stroke, are the main leading causes of deaths—almost 90% worldwide. These diseases also have social and economic costs. Cardiovascular diseases, for example, cost the economy of the European Union about 210 billion Euro in 2015. One method some European countries adopted to try to reduce the death rate from those leading causes was to impose high taxes on sugar-sweetened beverages. Assume that your next president loves the idea of sugar taxes and proposes a 30% tax on all sugary beverages in the country. And assume you are a marketing manager at a company that makes sugary soft drinks. The owner of the company heard the news and came to you for advice and asked you the following questions: So, buddy, should I be worried about our business if this sugar tax policy is implemented?
