2002 Great Plains Economics Challenge
Round I Microeconomics
 

1.                   D,  the main reason for high living standards or material well being for various countries around the world is the growth in productivity. For example labor productivity is defined as output per worker hour. High productivity means that for each hour worked, workers produce more real goods and services than low productivity workers.  

2.                   C,  driver’s training is not a public good.  Public goods present a unique economic problem because firms have little incentive to produce them. Few buyers are willingly to pay for nonexcludeable goods because they can get them for free. Once the good is produce it is difficult to exclude individuals for using it.  Individuals can receive benefits from using the good without having to pay, because it is difficult to exclude them. 

3.                   D,  in economics capital is physical capital.  Capital goods that are used to produce other goods and services. Machinery, equipment, tools, buildings, computers and wrenches are examples of physical capital. 

4.                   C,  the law of demand says that there is an inverse or negative relationship between price of a good and quantity demanded. When the price of a good falls, holding other things constant, such as income, tastes and preference, and price of related goods, the quantity purchased rises. 

5.                   A, offering rebates in the form of cash back or low interest financing are used by car manufacturers to lower car prices. They understand that by lower prices more cars will be sold because there is an inverse relationship between price and quantity demanded. Lower prices will help reduce a surplus on a market. 

6.                   B,  the opportunity cost of something is the value of what someone must sacrifice or give up for it. The opportunity cost of ten monitors is other goods, which could be produced with the resource that produced the ten monitors. 

7.                   A,  the definition of economic growth is a rise in real GDP per person. If there are more real goods and services available per person, then the average citizen, roughly speaking, gets a larger quantity of real goods and services. 

8.                   B,  a price control in the form of a price ceiling is the highest price at which the government allows people to buy or sell the good.  In the American Revolution case the price was set below equilibrium. A price ceiling below equilibrium results is quantity demanded being greater than quantity supplied. Shortages develop in the market. Since it is not as profitable to produce the price controlled goods, firms produce another good that do not have a government mandated price. 

9.                   C, if the price of cookies fall, given a downward sloping demand curve, a larger quantity of cookies will be demanded. This is the law of demand. There is an inverse or negative relationship between price of a good and quantity demanded. 

10.               C, when the government banned cigarette advertising on radio and television, cigarette manufactures increased other forms of advertising, such as billboards and magazines. An increase in magazine advertising by cigarette manufactures increased the demand for limited advertising space in magazines. An increase in demand with limited increase in supply would increase the price for all magazine ads. 

11.               C, one of the assumptions of a purely competitive firm is that it provides such a small part of total output that doubling output or withholding output from the market has not affect on market price.  

12.               C,  price discrimination means charging different prices to different buyers for the same good. Two goods are not the same if their costs of production are different, so selling them at different prices would not constitute price discrimination. 

13.               D,  the absence of major barriers to entry allows new firms to enter an industry and reduce economic profits to zero over time.  Remember that zero economic profits do not mean that firms are not earning a profit, they are earning a normal profit for their product. 

14.               C,  the definition of long run is all inputs or resources are variable for a firm. In the short run, at least one input is fixed.  A plant is a fixed input. Selling a plant is a long run adjustment. 

15.               C,  if the government legally imposes a tax on either the buyer or seller the incidence of the tax will be shared. Incidence is who really pays the tax.  Given a downward sloping demand curve and upward sloping supply curve, a government imposed $2 tax will be shared by the buyer and seller. If the seller absorbs $1 and the buyer has to pay $1 more for the good, then the new equilibrium price will be $11.

Round II Macroeconomics
 

1.                   B,  supply side economics stress factors that affects the capacity of the economy to produce real goods and services. Reducing tax rates to encourage people to work harder, providing incentives for increased saving and investment and encouraging risk taking by starting new businesses are supply side concepts. 

2.                   D,  a reduction in personal income taxes would increase available income that could be spent or saved.  If people expect that inflation will be higher next year, then they increase their purchases now.  A decrease in interest rates lowers the total price of buying big-ticket items like houses and cars; as a result they would increase spending.  A reduction in the unemployment rate means more people are working and earning income so they will be spending more.  A decrease in stock prices reduces individual wealth and in some cases income, which likely results in reduced consumer spending. 

3.                   D, GDP measures the value of all-final goods and services produced in the economy in one year. It is a measure of productive activity.  A museum purchasing a painting is a transfer of ownership. No new Rembrandt were produced. 

4.                   D, the Federal Government finances deficit spending by issuing treasury bills, notes, and bonds. 

5.                   A, the index number in a base year is 100. If the index number in the current year is 300 it means that price have increase on average 200%. To keep up with inflation salaries must increase by an equal amount.
                         CPI in current year minus CPI base year

Inflation rate =  -------------------------------------------------   X 100

CPI base year 

6.                   C, buying of stocks and bonds in only a transfer of ownership and does not add to, or decrease the nation’s capital stock. 

7.                   A,  aggregate demand = consumption + investment + government spending + (exports – imports). 

8.                   C,  deficit spending and a federal government budget surplus are methods to moderate variations in real output, employment and income and are a part of fiscal policy.  Deficit spending is desirable when the economy is not at full employment.  Demand-pull inflation occurs when there is excessive aggregate demand and the federal government should reduce it’s spending by decreasing the size of the deficit or increasing it’s budget surplus. 

9.                   C, an increase in personal income taxes will decrease aggregate demand. When the federal government increases personal income taxes it reduces income people have to spend on real goods and services. In other words aggregate demand decreases. 

10.               D,  if people believe that the economy is strong, then they are more confident that they will keep their jobs and as a result are more willing to spend their current income on goods and services. Also, they are more willing to buy goods and services now and pay for them in the future by using credit (future income).  

11.               D, higher levels of saving and investment, which are used to develop new processes and products, will increase the capacity of the economy to produce goods and services. Greater potential for economic growth. Increased government regulation decreases the potential for economic growth.  Resources must be used to meet the new regulations. 

12.               C, the Federal Reserve will sell bonds in the open market, which reduces the amount of excess reserves in the banking system. Decreased reserves in the banking system increase the price of money (interest rate). The Discount Rate is the interest rate the Federal Reserve charges banks for short-term loans.  A higher Discount Rate will be passed on to bank customers.

13.               E, factual question.

14.               A, if the interest rate is 8% and inflation is 10%, then your real interest rate is –2%.  In this case the borrower in effect is being paid by the lender to borrow.  This can occur when there is unanticipated inflation. 

15.               C, inflation is a situation where on average prices are rising. The question is “why are prices increasing”?  Too much money chasing too few goods. The central bank has increased the money supply too rapidly.  2002 Great Plains Economic Challenge


International/Current Events 

1.                   B, factual question. 

2.                   B,  a strong dollar means that it takes fewer dollars to buy a unit of a foreign currency. It takes fewer dollars to buy foreign goods. A stronger U.S. dollar makes goods produced in foreign countries relatively cheaper for American to buy.  Americans will buy more goods produced in foreign countries and fewer goods produced in the U.S..  Sales of exporters decline.  A lower aggregate demand for U.S. made goods results and increased imports and decreased exports leads to a worsening trade deficit. 

3.                   B, if a Euro costs 50 cents and a car costs 40,000 Euro, then .50 X 40,000 = $20,000. 

4.                   C, increased tariffs on foreign steel benefits U.S. firms and workers involved in steel production hurts users of U.S. steel because they must pay higher prices for input, steel.  

5.                   A, the theory of comparative advantage evaluates relative opportunity costs. We must examine relative costs of producing widgets and cogs in countries X and Y. In country X with a given amount of resources it can produce either 5 cogs or 10 widgets. The opportunity cost of producing 5 cogs is 10 widgets (1 cog = 2 widgets) and 1 widget = ½ cog. In country Y the opportunity cost of producing 2 cogs is 8 widgets (1 cog = 4 widgets) and 1 widget = ¼ cog. The cost of producing 1 cog is 2 widgets in country X and 4 in country Y.  Country X should specialize in the production of cogs and sell them to Y. In terms of widgets relative cost is lower in country Y. Gains from specialization and trade are maximized if Country Y imports cogs and exports widgets. 

6.                   B, given the initial condition of 10% interest rates in each country and then a decline in interest rates in the U.S. to 5% and no change in inflation in either country. The U.S. dollar will depreciate against the Won.  U.S. investors will experience a higher return on investment if they purchase more South Korean securities. U.S. investors must sell U.S. dollars in order to buy South Korean Won. Increased dollars supplied in currency markets and increased demand for won leads to a decreased value for the dollar (depreciation). 

7.                   B, the Japanese have few natural resources. 

8.                   B, for voluntary trade to occur there must be gains for both countries. Increased trade generally leads to lower product prices, increased labor productivity in both countries, greater availability of products in both countries and a net gain in new jobs in both countries. 

9.                   D, factual question. 

10.               B, given a $20,000 per capita income in the U.S., a 1% growth results in a $200 increase. Pakistan would need a 20% increase in per capita income to achieve the same dollar amount of change. 

11.               E, increased Mexican exports increased the demand for pesos. Decreased travel by Mexicans in the U.S. decreases the supply of pesos. Increased flow of capital to Mexico for investment purposes increases the demand for pesos. Increased demand for pesos and decreased supply increases the value of the peso (appreciation). 

12.               D, special interest groups are net gainers from barriers to trade. 

13.               E, factual question. 

14.               C, aggregate demand = consumption + investment + government spending + net exports (exports – imports). An increase in U.S. exports results in an increase in net exports, which will increase aggregate demand. Increased aggregate demand increases employment, increases U.S. GDP, increases the demand for U.S. dollars, puts upward pressure on prices and if there is no change in imports leaves unchanged U.S. demand for foreign currencies. 

15.               C, eliminating tariffs and other trade restrictions increase economic well being in the world. Increased specialization and trade leads to greater economic efficiency on a global scale.  Greater output of real goods and services on a global scale increases economic well being.
