Question 7
Purchasing power parity or PPP says the ratios composed of:
interest rates explain the direction of exchange rates.
growth rates explain the direction of exchange rates.
inflation rates explain the direction of exchange rates.
services explain the direction exchange rates.
public opinion polls explain the direction of exchange rates.
Question 8
If Ben Bernanke, Chair of the Federal Reserve Board, begins to tighten monetary policy by raising US interest rates next year, what is the likely impact on the value of the dollar?
The value of the dollar falls when US interest rates rise.
The value of the dollar rises when US interest rates rise.
The value of the dollar is not related to US interest rates.
This is known as Purchasing Power Parity or PPP.
Question 9
If the British pound (£) appreciates by 10% against the dollar:
both the US importers from Britain and US exporters to Britain will be helped by the appreciating pound.
the US exporters will find it harder to sell to foreign customers in Britain.
the US importer of British goods will tend to find that their cost of goods rises, hurting its bottom line.
both US importers of British goods and exporters to Britain will be unaffected by changes in foreign exchange rates.
Question 10
Trading partners should specialize in producing goods in accordance with comparative advantage, then trade and diversify in consumption because
out-of-pocket costs of production decline
free trade areas protect infant industries
economies of scale are present
manufacturers face diminishing returns
more goods are available for consumption
Question 11
Using demand and supply curves for the Japanese yen based on the $/¥ price for yen, an increase in US INFLATION RATES would
Decrease the demand for yen and decrease the supply of the yen.
Increase the demand for yen and decrease the supply of the yen.
Increase the demand and increase the supply of yen.
Decrease both the supply and the demand of yen.
Have no impact on the demand or supply of the yen.
Question 12
An increase in the exchange rate of the U.S. dollar relative to a trading partner can result from
higher anticipated costs of production in the U.S.
higher interest rates and higher inflation in the U.S.
higher growth rates in the trading partner's economy
a change in the terms of trade
lower export industry productivity
Question 13
The purchasing power parity hypothesis implies that an increase in inflation in one country relative to another will over a long period of time
increase exports
reduce the competitive pressure on prices
lower the value of the currency in the country with the higher inflation rate
increase foreign aid
increase the speculative demand for the currency
Question 14

negative returns to scale
Question 18
Which of the following is never negative?
marginal product
average product
production elasticity
marginal rate of technical substitution
slope of the isocost lines
Question 19
The primary purpose of the Cobb-Douglas power function is to:
allow one to make estimates of cost-output relationships
allow one to make predictions about a resulting increase in output for a given increase in the inputs
aid one in gaining accurate empirical values for economic variables
calculate a short-run linear total cost function
Question 20
According to the theory of cost, specialization in the use of variable resources in the short-run results initially in:
decreasing returns and declining average and marginal costs
increasing returns and declining average and marginal costs
increasing returns and increasing average and marginal costs
decreasing returns and increasing average and marginal costs
Question 21
What method of inventory valuation should be used for economic decision-making problems?
book value
original cost
current replacement cost
cost or market, whichever is lower
historical cost

The marginal cost function intersects the average fixed cost function where the average variable cost function is a minimum.
The marginal cost function intersects the average variable cost function where the average variable cost function is a minimum.
