ECO2013 Principles of Macroeconomics Final Exam Dr. Cody Reinhardt University of West Florida, Spring 2021 Instructions The final exam will be take-home style, posted May 4th at 9 AM and due May 6th at 10 AM. After completion, you should scan and upload your test as a single .pdf file You can email it to me or submit it on canvas, I will have a submission available under assignments. It is VERY important that you do not collaborate or share answers with other students, or use answers you found online from an outside source. Submissions will be scanned with plagiarism software to see if answers are copied.
It is the responsibility of the student to understand academic honesty policy. If you are concerned or unsure about something in regards to this, please ask before you submit. This exam has 12 questions. You will choose only 10 questions to answer and submit. This choosing serves two purposes: It allows students to select questions for which they are most knowledgeable and confident, and it helps me to determine which questions might be unclear or overly complicated when students largely don’t answer them.
Answers are to be either typed or hand-written and scanned into 1 .pdf document. There are a few online resources to combine individual pdfs into one, and if you are typing, you likely will need to insert images for graphing parts (unless you are quite good in paint, word, ect at creating graphs.) Please only use photos of handwritten answers as a last resort. Be sure that you answer each question clearly and completely. Most will have multiple parts; each part should be addressed with at least a couple sentences. Examples must be explained, and math answers require you to show work.
Note that I don’t explicitly grade on spelling, grammar, ect, but I need to be able to understand your answer. The expectation for each question is between 0.25 and 0.5 page for your answer, assuming hand- written. . Perhaps you would rather be somewhere else, rather than taking this exam. Think about what you would rather be doing right now. Define opportunity cost, and then using this definition, explain your opportunity cost for taking this exam.
2. Draw and completely label a supply and demand graph showing the market of corn in the USA. The price of fertilizer, something corn producers use in the process of making corn, INCREASES. Show the effect this has on the market. (Hint: 1 line moves). Is the new equilibrium price higher or lower than before? .
How does the market price mechanism answer the following questions: • What goods will be produced? • How will production be done? (With what resources and with what technology) • To whom will goods be distributed? 4. Define expansionary monetary policy. What are the goals of such a policy? Give an example of a recent expansionary monetary policy. .
What are the four components of GDP? For each, provide one example and explain why your example fits with this component. 6. Suppose there are 250 working age population, 150 employed individu- als, and 30 unemployed individuals. With this information, calculation labor force participation and unemployment rate.
How do these two figures com- pare to recent figures in the US? . Define government surplus and deficit. Which has the US been tending to fall under? 8. Suppose the CPI says that prices increased 10% in 2020.
Would this mean that everyone is 10% worse off? In other words, how might CPI overstate the cost of price increases? . What is the primary factor which affects economic growth? What items affect the above factor? (Hint: there are . Define structural unemployment.
Give two reasons why structural un- employment has increased since the beginning of 2020 (Hint: Covid-19 and policy response related.) . Consider the following PPF graph: Give the definitions for an efficient point, inefficient point, and unattainable point. Identify one point on this graph for EACH, and explain why the point meets the definition. . Describe in detail the three uses of money in an economy. 8

Macroeconomics Final Exam SolutionsQuestion 1: Opportunity Cost
Opportunity cost is defined as the value of the next best alternative that must be forgone when making a choice (Mankiw, 2014). When faced with a decision, the true cost of choosing one option over another is not just the monetary costs involved, but also what is sacrificed in terms of time, enjoyment, or other valuable outcomes. For example, in the context of taking this exam, my opportunity cost may include attending a family gathering, where precious time could be spent with loved ones, or engaging in recreational activities such as spending a day at the beach. The value of those experiences is my opportunity cost for dedicating my time to complete this exam instead.
Question 2: Supply and Demand for Corn
In the market for corn in the USA, an increase in the price of fertilizer—an essential input for corn production—would affect the supply side of the economy. The demand and supply graph will show the initial equilibrium where the original supply curve (S1) intersects with the demand curve (D1) at price P1 and quantity Q1. When the price of fertilizer rises, the cost of producing corn also increases, leading producers to supply less corn at each price. Thus, the supply curve shifts leftward from S1 to S2, resulting in a new equilibrium point where the market price is P2 and the quantity is Q2. It is evident that the new equilibrium price P2 is higher than the original price P1 due to the decrease in supply (Pindyck & Rubinfeld, 2018).
Question 3: Market Price Mechanism
The market price mechanism addresses the following fundamental economic questions:
1. What goods will be produced? – Goods are produced based on consumer preferences and willingness to pay. Higher demand for a particular good encourages producers to allocate resources toward its production (Samuelson & Nordhaus, 2010).
2. How will production be done? – The production method depends on the availability of resources and the technology used. Producers often adopt the most efficient technology to maximize profitability, which can involve investments in capital goods and human capital training (Stiglitz, 2009).
3. To whom will goods be distributed? – Goods are primarily distributed based on purchasing power. Those who can afford to pay higher prices will obtain goods, reflecting income distribution in the economy (Mankiw, 2014).
Question 4: Expansionary Monetary Policy
Expansionary monetary policy involves increasing the money supply and decreasing interest rates to stimulate economic activity (Blanchard, 2017). The primary goals of this policy are to boost aggregate demand, reduce unemployment, and avoid deflation. An example of a recent expansionary monetary policy is the Federal Reserve’s response to the COVID-19 pandemic in 2020, where the Fed slashed interest rates to near zero and implemented large-scale asset purchases to inject liquidity into the economy (Yellen, 2020).
Question 5: Components of GDP
The four components of GDP are consumption, investment, government spending, and net exports:
1. Consumption: This includes all private expenditures by households. For example, spending on durable goods such as cars exemplifies consumption (Mankiw, 2014).
2. Investment: This encompasses business investments in capital goods. An example would be a company purchasing new machinery to increase production capacity (Blanchard, 2017).
3. Government Spending: This focuses on government expenditures on goods and services. For instance, spending on public education is categorized as government spending and contributes to GDP (Samuelson & Nordhaus, 2010).
4. Net Exports: This is calculated as exports minus imports. A country that exports more than it imports, like China, would have a positive net export component to its GDP (Krugman & Obstfeld, 2018).
Question 6: Labor Force Participation and Unemployment Rates
To calculate the Labor Force Participation Rate (LFPR) and the Unemployment Rate (UR):
- Labor Force = Employed + Unemployed = 150 + 30 = 180
- Labor Force Participation Rate = (Labor Force / Working Age Population) × 100 = (180 / 250) × 100 = 72%
- Unemployment Rate = (Unemployed / Labor Force) × 100 = (30 / 180) × 100 = 16.67%
As of 2021, the labor force participation rate in the U.S. was around 61.5%, which indicates a significant drop compared to our example, largely attributed to factors like labor market changes following the COVID-19 pandemic (Bureau of Labor Statistics, 2021).
Question 7: Government Surplus and Deficit
A government surplus occurs when its revenues exceed its expenditures, whereas a deficit signifies that expenditures surpass revenues (Blanchard, 2017). In recent years, the U.S. has predominantly been in a deficit scenario due to extensive government spending initiatives, especially in response to economic downturns and policy measures like the American Rescue Plan (Congressional Budget Office, 2021).
Question 8: Cost of Price Increases and CPI
A 10% increase in the Consumer Price Index (CPI) does not imply that everyone is 10% worse off. The CPI can overstate the cost of living increases due to substitution bias, where consumers may alter their purchasing behavior in response to price changes (Bureau of Labor Statistics, 2019). Additionally, new products and improvements in quality are not adequately captured, leading to a potentially inflated perception of price increases (Cagan, 2020).
