Exchange Rates, International Payments & Price Effects — Practice · Grade 12 Social Studies

Chapter: Global Connections, Risk & Economic Inquiry

What this practice covers

By the end of Exchange Rates, International Payments & Price Effects you should be able to:

8 questions, written answer, each with a worked explanation.

Vocabulary used: exchange rate, appreciation, depreciation, currency exposure, reciprocal quotation.

Problem 1

Why must an exchange quotation state its units?
Answer and explanation

The units determine the conversion direction. Dollars per euro multiplies a euro amount into dollars, while the reciprocal quote works in the other direction. An unlabeled number cannot establish which currency strengthened or what an item costs.

Problem 2

Why can the same rate change help one purchaser and raise another’s converted cost?
Answer and explanation

They hold different currencies and face prices stated in different units. The fixed euro item becomes costlier in dollars, while a fixed dollar item becomes cheaper in euros. Contracts, fees, and price responses may change real outcomes.

Problem 3

Why does depreciation not guarantee a higher exporter profit?
Answer and explanation

Input costs, contracts, demand, quantities, and financing can also change. A converted sales-price advantage is one channel, not the whole profit calculation. Examine the firm’s currency exposures and relevant records.

Problem 4

What should a plan do when its future exchange rate is uncertain?
Answer and explanation

State the assumed quotation, convert with units, test alternative rates and costs, and identify the obligation’s timing. Do not treat one quote as a guaranteed future amount or omit charges from a real comparison.

Problem 5

Invented rates change from $1.00 per euro to $1.20; item price stays €100; fees are excluded. Calculate dollar prices and identify the currencies’ changes.
Answer and explanation

The price converts from $100 to $120, a twenty percent increase in dollar cost under the assumptions. The euro appreciates and the dollar depreciates relative to each other. The exercise does not establish actual market rates, purchases, or profit effects. Seller prices, fees, contracts, and demand are held outside this simple conversion.

Multiply €100 by each dollar-per-euro rate.

Compare $100 and $120.

State price-response limits.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 6

Does a stronger currency improve every domestic business’s outcome?
Answer and explanation

No. Import costs, export prices, inputs, debts, contracts, and demand differ. Identify the business’s exposures and compare channels rather than applying one directional label as a universal verdict.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 7

Invented rate $1.25 per euro and price €80, excluding fees. Calculate dollars and the reciprocal rate.
Answer and explanation

The price is $100. The reciprocal rate is €0.80 per dollar. Units establish the conversion direction; the example is not a current market quotation or a complete transaction cost.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 8

A fictional exporter’s sales are in dollars and inputs in euros. Why must an exchange-rate profit forecast consider both?
Answer and explanation

Dollar revenue and euro-input costs respond through different channels and conditions. Quantities, contracts, prices, and other costs can also change. A converted export-price advantage does not alone establish the net profit effect.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.
