Business Cycles, Employment & Inflation — Practice · Grade 12 Social Studies

Chapter: Measuring the Economy & Public Policy

What this practice covers

By the end of Business Cycles, Employment & Inflation you should be able to:

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

Vocabulary used: labor force, unemployment rate, inflation, disinflation, real income.

Problem 1

Why can an aggregate expansion coexist with hardship in one region?
Answer and explanation

The aggregate combines different sectors and places. Growth elsewhere or productivity changes can offset local losses. Use regional and distributional evidence instead of assigning the national direction to every household.

Problem 2

Why can unemployment fall without additional employment in the example?
Answer and explanation

Five people leave the measured labor force instead of becoming employed. Both the unemployment count and denominator change. The rate falls to about 5.26 percent while employment remains 90, so job creation cannot be inferred from the rate alone.

Problem 3

What is the difference between disinflation and deflation?
Answer and explanation

Disinflation is a lower positive rate of price increase; deflation is an actual price-index decline. Prices can keep rising when inflation slows. Identify the index and period rather than interpreting a smaller rate as falling prices.

Problem 4

Why can a nominal pay increase coexist with lower real purchasing power?
Answer and explanation

Prices can rise faster than pay. In the supplied example, dividing 1.04 by 1.05 gives a slight real decline. State the price measure and period; different household purchases or employment circumstances may produce different experiences.

Problem 5

Invented population: 90 employed, ten unemployed under the stated classification, 40 outside the labor force. Price index moves from 120 to 126 over one year. Calculate unemployment and inflation, and state one limitation.
Answer and explanation

Unemployment is ten percent of the 100-person labor force. Inflation is five percent over the stated year. Neither measure uses the entire 140-person population as its denominator, and six index points are not six percent. The measures do not reveal every household’s work needs or exact purchase-price change; participation and distributional evidence would add context.

Use the 100-person labor force.

Divide index change by 120.

Keep classifications and household experience separate.

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 slower inflation mean prices returned to their old level?
Answer and explanation

No. Positive but slower inflation means the index continues rising at a reduced rate. A fall in the price level is a different condition. Distinguish the level, change, rate, and period.

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 index rises from 200 to 210. Calculate inflation; income rises five percent in the same period. What is modeled real income growth?
Answer and explanation

Inflation is five percent, and 1.05/1.05−1 gives zero modeled real growth under that index. The income amount rises while purchasing power remains unchanged in this comparison. Household-specific prices and other conditions may differ.

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

Invented labor force has 180 employed and 20 unemployed. Ten unemployed leave the labor force with employment unchanged. Calculate both rates.
Answer and explanation

The original rate is 20/200, ten percent; the later rate is 10/190, about 5.26 percent. Employment remains 180. A falling unemployment rate alone therefore cannot establish new jobs; participation also changed.

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.
