Macroeconomics Exam Review

The unique point at which the supply and demand curves intersect is called equilibrium. At this point, the quantity of goods or services supplied matches the quantity demanded in the market. It represents a state of balance where there is no excess supply or demand, resulting in market stability. The concept of equilibrium is fundamental in economics as it helps determine prices and quantities in a market.

An export refers to a good that is produced within a country and then sold to customers in other countries. It involves the process of sending goods or services from the domestic market to international markets. This can contribute to economic growth and development as it allows domestic producers to expand their customer base and earn foreign exchange. Exporting can also lead to increased competitiveness and specialization in certain industries, as well as fostering international trade relationships and promoting global integration.

The real interest rate is calculated by subtracting the rate of inflation from the nominal interest rate. In this case, the nominal interest rate is 11.5 percent and the rate of inflation is 6.3 percent. Subtracting 6.3 percent from 11.5 percent gives us a real interest rate of 5.2 percent. Therefore, the correct answer is 5.2%.

Increases in interest rates are unlikely to trigger increases in output because higher interest rates make borrowing more expensive for businesses and consumers. This reduces their ability and willingness to invest and spend, leading to a decrease in output. On the other hand, increases in the labor force, labor productivity, and consumer spending can all contribute to higher levels of output as they increase the availability of resources and demand in the economy.

Consumer surplus is the difference between the maximum price a consumer is willing to pay for a good and the actual price they pay. In this case, the consumer is willing and able to pay 22 for the good but only pays 12. Therefore, the consumer surplus is calculated by subtracting the actual price (12) from the maximum price (22), which equals 10. This means that the consumer benefits by 10 units of value from purchasing the good at a lower price than they were willing to pay.

Lucy starting her own psychiatric practice and her expenditures exceeding her income suggests that she requires additional funds to cover the expenses. As a result, she becomes a borrower who demands money from the financial system. This means that she is seeking financial assistance to support her practice and cover the shortfall between her income and expenses.

The correct answer is inflation. Inflation refers to the general increase in prices of goods and services over time. It erodes the purchasing power of money, causing the value of income or GDP to decrease in real terms. Nominal income or GDP represents the current value, while real income or GDP adjusts for the effects of inflation, providing a more accurate measure of economic growth or individual purchasing power. Therefore, the difference between real and nominal income or GDP arises due to inflation.

National savings is the sum of public savings and private savings in a closed economy. In this case, the public savings are negative 2 trillion, indicating that the government is running a deficit. The private savings are 5 trillion. Therefore, the national savings can be calculated by adding the public and private savings, resulting in 3 trillion.

The correct answer is the federal reserve. The federal reserve is responsible for controlling the money supply in the United States. It does this through various tools such as setting interest rates, regulating banks, and conducting open market operations. The president and congress have some influence over economic policies, but the actual control over the money supply lies with the federal reserve.

All of the options mentioned - human capital per worker, physical capital per worker, and natural resources per worker - are determinants of productivity. Human capital refers to the knowledge, skills, and abilities possessed by individuals, which can greatly impact their productivity. Physical capital, such as machinery and equipment, can enhance productivity by enabling workers to perform tasks more efficiently. Natural resources, such as raw materials and energy sources, are essential inputs for production and can influence productivity levels. Therefore, all of these factors contribute to determining productivity.

A tax on an imported good is called a tariff. A tariff is a tax imposed by a government on goods that are imported into a country. It is designed to make imported goods more expensive and less competitive compared to domestically produced goods. Tariffs are used to protect domestic industries, promote local manufacturing, and generate revenue for the government. By imposing tariffs, the government aims to regulate international trade and maintain a balance between domestic and foreign goods.

The correct answer is 75000. This is calculated by dividing the reserve ratio (2%) into 1, which gives us a multiplier of 50. Then, we multiply this multiplier by the amount of additional deposits ($1500) to find that $75,000 in new money is created.

The correct answer is "all of the above" because whenever the federal budget shows a deficit, it means that the government is spending more money than it is bringing in through revenue. In order to cover this deficit, the federal government borrows money, which contributes to the growth of the U.S. federal debt. One of the ways the government borrows money is by issuing treasury securities, such as Treasury bonds, bills, and notes, which are purchased by investors. Therefore, all three statements are true and contribute to the growth of the U.S. federal debt.

If the exchange rate is 1.15 Canadian dollars per US dollar, it means that 1 US dollar is equivalent to 1.15 Canadian dollars. Therefore, to find the cost of the watch in Canadian dollars, we need to multiply the cost in US dollars (145) by the exchange rate (1.15). This gives us 166.75 Canadian dollars.

When the consumer price index rises, it means that the overall prices of goods and services have increased. This implies that the cost of purchasing the same goods and services will also increase. Therefore, the typical family will have to spend more dollars to purchase the same goods. This can lead to a decrease in their purchasing power and potentially affect their standard of living.

The demand for money is determined by consumers, firms, investors, and other economic agents. These individuals and entities require money to carry out transactions, make purchases, invest, and meet their financial obligations. The demand for money is influenced by factors such as income levels, interest rates, inflation expectations, and the overall state of the economy. As these factors change, the demand for money can fluctuate, impacting economic activity and monetary policy decisions.

The correct answer is 720. The reserve ratio is given as 6 percent, which means the bank must hold 6 percent of its deposits as reserves. To calculate the amount of reserves, we multiply the reserve ratio (0.06) by the amount of deposits (12,000). Therefore, 0.06 x 12,000 = 720.

The purchase of tickets to watch the Texas Longhorns get crushed by the Oklahoma Sooners in the annual Red River Shootout game exemplifies the function of money as a medium of exchange. In this scenario, money is being used to facilitate the exchange of tickets for the opportunity to attend the game. The transaction involves the transfer of money from the fan to the seller in exchange for the tickets, demonstrating the role of money as a medium that enables the exchange of goods or services.

Based on the given table, Mike is willing to pay 50.00 and Sandy is willing to pay 30.00 for the product. Since the price of the product is 22, both Mike and Sandy would be willing to purchase the product. Therefore, the answer is "mike, sandy".

If the country specializes in the good in which it has a comparative advantage (baseballs) and trades half of that good to the other country, it will consume 100 baseballs and 500 bananas. This is because the country can produce baseballs at a lower opportunity cost than the other country, so it is more efficient for them to specialize in baseball production. By trading half of their baseballs, they can acquire 500 bananas from the other country.

Trade between nations is based on comparative advantage. This means that countries specialize in producing goods or services in which they have a lower opportunity cost compared to other countries. By focusing on producing what they are relatively more efficient at, countries can maximize their output and trade the surplus with other nations. This leads to increased efficiency and overall economic growth as countries can benefit from the differences in their resources, skills, and technology. Strategic alliances, consumer preferences, and absolute advantage may also play a role in international trade, but comparative advantage is the main driving force behind it.

Comparisons of per capita gross domestic product between countries provide a good measure of relative living standards. Per capita GDP is a commonly used indicator to compare the average income and economic well-being of individuals in different countries. It takes into account the total economic output of a country and divides it by the population, providing an estimate of the average income per person. By comparing per capita GDP across countries, we can gain insights into the relative standards of living and economic prosperity among different nations.

The nominal exchange rate can be calculated by dividing the price of goods in one currency by the price of goods in another currency. In this case, the price of goods in euros is 480 and the price of goods in dollars is 550. Dividing 480 by 550 gives us approximately 0.87 euros per dollar. Therefore, the correct answer is .87 euros per dollar.

An increase in interest rates does not increase aggregate demand because it typically leads to a decrease in borrowing and spending by consumers and businesses. Higher interest rates make borrowing more expensive, which discourages people from taking out loans to make purchases or invest in new projects. This reduction in borrowing and spending reduces overall demand in the economy, leading to a decrease in aggregate demand.

When we minimize waste, we are considered efficient because we are utilizing resources effectively and not wasting unnecessary materials or energy. This approach helps to optimize processes, reduce costs, and improve overall productivity. Being efficient is an important aspect of sustainability and environmental responsibility as it helps to conserve resources and reduce negative impacts on the environment.

A price floor is a legal minimum at which a good or service may be sold. This means that the government sets a minimum price that must be charged for a particular product or service. This can be done to protect producers or workers in a specific industry by ensuring they receive a fair price for their goods or services. By setting a price floor, the government aims to prevent prices from falling too low and potentially harming businesses or workers. Therefore, the correct answer is that a price floor is a legal minimum at which a good or service may be sold.

The natural rate of unemployment refers to the unemployment rate that prevails when there is full economic output. This means that all available resources in the economy are being utilized efficiently, and there is no cyclical unemployment caused by a lack of demand or economic downturns. It represents the lowest level of unemployment that can be sustained without causing inflationary pressures in the economy.

The given equation MS=(PxY)/V represents the quantity theory of money, where MS is the money supply, P is the price level, Y is the real GDP, and V is the velocity of money. The equation (P x Y)/V is derived from the original equation by rearranging terms. It suggests that the velocity of money (V) is equal to the ratio of the price level (P) multiplied by the real GDP (Y) divided by the money supply (M). This equation helps to understand the relationship between the velocity of money and other variables in the quantity theory of money.

The "core" rate of inflation excludes changes in gold prices from the normal measures of inflation. This is because gold prices can be highly volatile and influenced by factors such as geopolitical events and investor sentiment, which may not accurately reflect the overall trend of inflation in an economy. By excluding gold prices, economists can focus on the underlying inflationary pressures in the economy, such as changes in the prices of goods and services, without the distortion caused by fluctuations in gold prices.

If the federal reserve increases the money supply at approximately the growth rate of output, the inflation rate should be near zero. This is because when the money supply increases at the same rate as the growth in output, there is a balance between the supply of money and the demand for goods and services. This prevents excessive inflation as there is no excess money chasing too few goods. Therefore, the inflation rate should remain low and stable.

The correct answer is 480. This is because consumer surplus is calculated as the area between the demand curve and the price line up to the quantity consumed. In this case, the price floor is set at $8 per unit. The demand curve intersects the price floor at a quantity of 80 units. Using the formula for the area of a triangle (1/2 * base * height), the base is 80 units and the height is the difference between the equilibrium price and the price floor, which is $12 - $8 = $4. Therefore, the consumer surplus is equal to 1/2 * 80 * 4 = $480.

The opportunity cost of moving from point C to point B is 100 bananas. This means that if someone decides to move from point C to point B, they would have to give up the opportunity to have 100 bananas. This suggests that there is a trade-off involved in this decision, where the person would have to sacrifice the benefit of having 100 bananas in order to make the move.

A depreciation of the US real exchange rate means that the value of the US dollar has decreased relative to other currencies. This makes foreign goods relatively more expensive for US consumers and domestic goods relatively cheaper. As a result, US consumers are likely to buy more domestic goods because they are now more affordable, while they may buy fewer foreign goods because they have become more expensive. Therefore, the correct answer is "more domestic and fewer foreign goods."

The given answer, "metzger," is the correct answer because it is the only option that is a name. The other options, "dude," "butch," and "skip," are not typically used as names for professors. Therefore, "metzger" is the most likely choice for the professor's name.

The high rates of inflation in the 1970s and early 1980s have been shown to be primarily due to rapid money supply growth. This means that the increase in the amount of money circulating in the economy led to an increase in prices. As more money was available, people had more purchasing power, which drove up demand and ultimately caused inflation. This explanation is supported by economic research and analysis of the time period.

A tax cut would tend to cause real GDP per person to rise because it would increase disposable income and incentivize consumer spending. With more money in their pockets, individuals would have more purchasing power, leading to increased demand for goods and services. This, in turn, would stimulate economic growth and potentially lead to higher production levels, job creation, and overall economic expansion.

Cyclical unemployment refers to short-term fluctuations in the unemployment rate around its natural rate. This means that during economic downturns or recessions, there is an increase in unemployment as businesses reduce their workforce. Conversely, during economic expansions, unemployment decreases as businesses hire more workers. These fluctuations are temporary and are caused by changes in the overall demand for goods and services in the economy. Cyclical unemployment is different from other types of unemployment, such as structural or frictional unemployment, which are not directly related to the business cycle.

Historically, it has been observed that higher unemployment leads to lower wages, not higher wages. This is because when there is a surplus of labor in the market, employers have more bargaining power and can offer lower wages. Conversely, when there is low unemployment, there is a scarcity of labor, leading to increased competition among employers for workers, which can drive up wages.

The growth rate of real GDP per person can be calculated by finding the percentage increase from the initial value to the final value. In this case, the initial value is 3950 and the final value is 5700. The difference between these two values is 5700 - 3950 = 1750. To find the percentage increase, we divide this difference by the initial value and multiply by 100. (1750/3950) * 100 = 44.3%. Therefore, the growth rate of real GDP per person is 44.3%.

The opportunity cost of 1 bushel of wheat in Texas is 8 bushels of oats. This means that if Texas chooses to produce 1 bushel of wheat, it would have to give up the opportunity to produce 8 bushels of oats. This indicates that the production of oats has a higher opportunity cost compared to wheat in Texas.

Increases in the rate of growth in the money supply have been shown to most likely result in higher rates of inflation. This is because when there is more money in circulation, the purchasing power of each unit of currency decreases, leading to a general increase in prices. As a result, consumers and businesses need more money to buy goods and services, which leads to an overall increase in the level of inflation in the economy.

The total adult male population in Metzgerland is 70 million because the table shows that there are 12 million males not in the labor force, 8 million males unemployed, and 50 million males employed. Adding these three categories together gives a total of 70 million adult males in Metzgerland.

A recession is defined as a period of economic decline characterized by a significant decrease in the total production of goods and services, which is represented by falling output. This decline in output is typically accompanied by a decrease in employment opportunities, as businesses reduce their production levels and lay off workers. While rising unemployment may be a consequence of a recession, it does not define it. Rising prices and falling stock prices are not direct indicators of a recession, as they can be influenced by other factors.

The given answer suggests that if Texas and California were to specialize and engage in trade that would benefit both states, Texas would focus on producing oats while California would focus on producing wheat. This specialization would allow each state to focus on producing the product they have a comparative advantage in, leading to increased efficiency and overall economic benefits for both states.

The correct answer is "inflation rate in 2005= CPI in 2005- CPI in 2004 x 100 / CPI in 2004". This formula calculates the inflation rate in 2005 by subtracting the CPI (Consumer Price Index) in 2004 from the CPI in 2005, and then dividing the result by the CPI in 2004. This formula is commonly used to measure the percentage change in prices over time and determine the inflation rate.

The given answer suggests that the number of unemployed individuals increased by 110,000. This is because 100,000 people lost their jobs or quit, and an additional 10,000 job seekers started looking for work. Therefore, the total number of unemployed individuals increased by the sum of these two figures, which is 110,000.

The correct answer is 4.35%. The reserve ratio is calculated by taking the reciprocal of the money multiplier. In this case, the money multiplier is 23, so the reserve ratio would be 1/23, which is equal to 0.0435 or 4.35%.

The quantity equation states that the money supply (M) multiplied by the velocity of money (V) is equal to the price level (P) multiplied by the real output of goods and services (Y). If V is constant over time and Y is not impacted by nominal variables, then any changes in the price level (P) can only be explained by changes in the money supply (M). Therefore, the correct answer is "changes in money supply".

A price floor will be binding only if it is set above equilibrium price. This means that the government has set a minimum price for a good or service that is higher than what the market would naturally determine as the equilibrium price. When the price floor is above the equilibrium price, it creates a surplus of the good or service, as suppliers are willing to supply more than what consumers demand at that higher price. This surplus indicates that the price floor is binding, as it is causing a market imbalance.
