6.    Given diagrams for the money market, Investment demand, and the AD-AS model, be able to identify what must occur to the money supply in order to achieve potential GDP

Part B: Problem-Solving Questions

 

Pact C: Short Essay Questions

Chapter 6

1.    What are the three primary measures used in macroeconomics to assess the performance of an economy?

a.    GDP, unemployment rate, and inflation rate

2.    Evaluate the statement that "unexpected declines in demand, with inflexible prices, generate a rise in unemployment and a fall in output."

a.    The statement is correct in describing the effects of an unexpected decline in demand in an economy with sticky prices. In the short run, when demand decreases unexpectedly and prices cannot adjust quickly, businesses reduce production, leading to higher unemployment and a decline in output.

Chapter 7

1.    Define the four categories of expenditures that comprise GDP.

a.    Consumption (c), Investment (i), government spending (g), net exports (nx)

2.    Discuss the shortcomings of using GDP as a measure of the economy's output performance and as a measure of its standard of living.

a.    Excludes non-market activities, ignores income inequality, excludes environmental costs, no measurement of quality of life, ignores informal economy, population size and distributions

Chapter 9

1.    Just as a household's income does not measure its total happiness, a nation's GDP does not measure its total well-being. Explain.

a.    While GDP measures economic activity, it does not capture the holistic aspects of well-being, such as happiness, equality, environmental health, or social stability, much like household income does not capture a family's overall happiness.

2.    What are two criticisms of the unemployment rate data? How do these criticisms relate to overstating or understating the unemployment rate?

a.    Two criticisms of the unemployment rate data are exclusion of discouraged workers and underemployment. Discouraged workers can understate the true level of unemployment as it doesn’t account for those who are no longer actively searching for work but still face difficulty finding employment. Underemployment can lead to an overstatement of employment situation, as people may be counted as employed even if they are not.

Chapter 8

1.    Which is more important, labor quantity or labor productivity, as a source of economic growth in the United States?

a.    Labor productivity is considered more important because it drives sustainable improvements in efficiency, innovation, and living standards.

2.    How does investment in capital goods and infrastructure contribute to economic growth?

a.    By enhancing productivity, reducing production costs, improving efficiency, and creating jobs

Chapter 20

1.    Explain how differences in relative price levels influence a nation’s relative exchange rate in a floating exchange rate system. What is the Big Mac Index and how can it predict movements in a floating exchange rate system?

a.    In a floating exchange rate system, differences in relative price levels between two countries influence the exchange rate because higher price levels (inflation) in one country make its goods more expensive relative to another country’s goods. The Big Mac Index is an informal tool that compares the price of a Big Mac hamburger in different countries. It uses the theory of purchasing power parity (PPP), which suggests that in the long run, exchange rates should adjust so that a basket of goods (like a Big Mac) costs the same in different countries, once exchange rates are considered.

2.    What are the economic effects of an appreciation of the dollar relative to foreign currencies?

a.    An appreciation of the dollar makes imports cheaper and exports more expensive for foreign buyers. This can reduce demand for U.S. exports and increase demand for imports, potentially slowing economic growth. However, it also helps control inflation by lowering the cost of imported goods.

Chapter 10

1.    How does a major tax change affect both the consumption schedule and saving schedule?

o   A major tax change affects both the consumption and saving schedules by altering disposable income. A tax cut increases disposable income, shifting the consumption schedule upward (more spending) and the saving schedule downward (less saving). A tax increase reduces disposable income, shifting the consumption schedule downward (less spending) and the saving schedule upward (more saving).

2.    What are two key facts that serve as the rationale for the multiplier effect?

o   Increased spending and re-spending

Chapter 12

1.    Explain how changes in the dollar's exchange rate can affect net exports and thus aggregate demand.

a.    Dollar depreciation reduces imports which boosts net exports and leads to an increase in aggregate demand. Dollar appreciation reduces exports which increases imports and reduces net exports which leads to a decrease in aggregate demand.

2.    The determinants of aggregate demand determine the location of the aggregate demand curve. What are the four basic determinants of aggregate demand?

a.    Consumption (C), investment (I), government spending (G), and net exports (NX)

Chapter 13

1.    Define expansionary fiscal policy. During which phase of the business cycle would it be appropriate to use?

o   Expansionary fiscal policy involves increasing government spending or cutting taxes to stimulate the economy. It is appropriate to use during a recession or when the economy is in a downturn to boost demand and reduce unemployment.

2.    Define contractionary fiscal policy. When should it be used?

o   Contractionary fiscal policy involves decreasing government spending or increasing taxes to slow down the economy. It should be used during periods of high inflation or when the economy is overheating to control price increases.

Chapter 15

1.    Trace the cause-effect chain that results from an expansionary monetary policy.

o   In an expansionary monetary policy, the central bank lowers interest rates or increases the money supply. This makes borrowing cheaper, which encourages spending and investment. As a result, demand for goods and services rises, leading to higher output and employment, which can boost economic growth.

2.    Differentiate between expansionary and contractionary/restrictive monetary policies.

o   Expansionary monetary policy involves lowering interest rates or increasing the money supply to stimulate economic activity during a downturn.

o   Contractionary (restrictive) monetary policy involves raising interest rates or reducing the money supply to control inflation and slow down an overheating economy.

1.    Be able to identify examples of the real balances effect, the interest rate effect, and the foreign trade effect

2.    Know why the short-run aggregate supply (AS) curve becomes steeper as it approaches potential output

a.    Due to the constraints and pressures that arise when the economy is near its capacity

3.    Know what happened to the aggregate demand (AD) curve as foreign incomes change

Part B: Problem-Solving Questions

 

Pact C: Short Essay Questions

Chapter 6

1.    What are the three primary measures used in macroeconomics to assess the performance of an economy?

a.    GDP, unemployment rate, and inflation rate

2.    Evaluate the statement that "unexpected declines in demand, with inflexible prices, generate a rise in unemployment and a fall in output."

a.    The statement is correct in describing the effects of an unexpected decline in demand in an economy with sticky prices. In the short run, when demand decreases unexpectedly and prices cannot adjust quickly, businesses reduce production, leading to higher unemployment and a decline in output.

Chapter 7

1.    Define the four categories of expenditures that comprise GDP.

a.    Consumption (c), Investment (i), government spending (g), net exports (nx)

2.    Discuss the shortcomings of using GDP as a measure of the economy's output performance and as a measure of its standard of living.

a.    Excludes non-market activities, ignores income inequality, excludes environmental costs, no measurement of quality of life, ignores informal economy, population size and distributions

Chapter 9

1.    Just as a household's income does not measure its total happiness, a nation's GDP does not measure its total well-being. Explain.

a.    While GDP measures economic activity, it does not capture the holistic aspects of well-being, such as happiness, equality, environmental health, or social stability, much like household income does not capture a family's overall happiness.

2.    What are two criticisms of the unemployment rate data? How do these criticisms relate to overstating or understating the unemployment rate?

a.    Two criticisms of the unemployment rate data are exclusion of discouraged workers and underemployment. Discouraged workers can understate the true level of unemployment as it doesn’t account for those who are no longer actively searching for work but still face difficulty finding employment. Underemployment can lead to an overstatement of employment situation, as people may be counted as employed even if they are not.

Chapter 8

1.    Which is more important, labor quantity or labor productivity, as a source of economic growth in the United States?

a.    Labor productivity is considered more important because it drives sustainable improvements in efficiency, innovation, and living standards.

2.    How does investment in capital goods and infrastructure contribute to economic growth?

a.    By enhancing productivity, reducing production costs, improving efficiency, and creating jobs

Chapter 20

1.    Explain how differences in relative price levels influence a nation’s relative exchange rate in a floating exchange rate system. What is the Big Mac Index and how can it predict movements in a floating exchange rate system?

a.    In a floating exchange rate system, differences in relative price levels between two countries influence the exchange rate because higher price levels (inflation) in one country make its goods more expensive relative to another country’s goods. The Big Mac Index is an informal tool that compares the price of a Big Mac hamburger in different countries. It uses the theory of purchasing power parity (PPP), which suggests that in the long run, exchange rates should adjust so that a basket of goods (like a Big Mac) costs the same in different countries, once exchange rates are considered.

2.    What are the economic effects of an appreciation of the dollar relative to foreign currencies?

a.    An appreciation of the dollar makes imports cheaper and exports more expensive for foreign buyers. This can reduce demand for U.S. exports and increase demand for imports, potentially slowing economic growth. However, it also helps control inflation by lowering the cost of imported goods.

Chapter 10

1.    How does a major tax change affect both the consumption schedule and saving schedule?

o   A major tax change affects both the consumption and saving schedules by altering disposable income. A tax cut increases disposable income, shifting the consumption schedule upward (more spending) and the saving schedule downward (less saving). A tax increase reduces disposable income, shifting the consumption schedule downward (less spending) and the saving schedule upward (more saving).

2.    What are two key facts that serve as the rationale for the multiplier effect?

o   Increased spending and re-spending

Chapter 12

1.    Explain how changes in the dollar's exchange rate can affect net exports and thus aggregate demand.

a.    Dollar depreciation reduces imports which boosts net exports and leads to an increase in aggregate demand. Dollar appreciation reduces exports which increases imports and reduces net exports which leads to a decrease in aggregate demand.

2.    The determinants of aggregate demand determine the location of the aggregate demand curve. What are the four basic determinants of aggregate demand?

a.    Consumption (C), investment (I), government spending (G), and net exports (NX)

Chapter 13

1.    Define expansionary fiscal policy. During which phase of the business cycle would it be appropriate to use?

o   Expansionary fiscal policy involves increasing government spending or cutting taxes to stimulate the economy. It is appropriate to use during a recession or when the economy is in a downturn to boost demand and reduce unemployment.

2.    Define contractionary fiscal policy. When should it be used?

o   Contractionary fiscal policy involves decreasing government spending or increasing taxes to slow down the economy. It should be used during periods of high inflation or when the economy is overheating to control price increases.

Chapter 15

1.    Trace the cause-effect chain that results from an expansionary monetary policy.

o   In an expansionary monetary policy, the central bank lowers interest rates or increases the money supply. This makes borrowing cheaper, which encourages spending and investment. As a result, demand for goods and services rises, leading to higher output and employment, which can boost economic growth.

2.    Differentiate between expansionary and contractionary/restrictive monetary policies.

o   Expansionary monetary policy involves lowering interest rates or increasing the money supply to stimulate economic activity during a downturn.

o   Contractionary (restrictive) monetary policy involves raising interest rates or reducing the money supply to control inflation and slow down an overheating economy.
