Key things to remember

  1. 1Business cycle phases in order: expansion, peak, contraction (recession), trough, recovery.
  2. 2Inflation = a general rise in prices. Inflation rate .
  3. 3The Bank of Canada raises its policy interest rate to slow inflation and lowers it to help a weak economy; its inflation target is 2%.
  4. 4Interest for one year
  5. 5Market structures from most to least competition: perfect competition, monopolistic competition, oligopoly, monopoly.
  6. 6Market share

Some years, it seems everyone is hiring, stores are busy and people are buying new cars. Other years, businesses lay off workers and families cut back. These ups and downs are normal; the economy moves in waves. A business owner who understands the wave can prepare: save money in good times, cut costs before a slowdown, and be ready to grow when things recover. In this lesson you will also see that some businesses have dozens of competitors while others have almost none, and that makes a big difference to how they set prices.

The five phases of the business cycle

The business cycle (or economic cycle) is the pattern of rises and falls in a country's economic activity over time. Economists measure activity using gross domestic product (GDP), the total value of all goods and services produced in a country in a year. When GDP grows, the economy is expanding; when it shrinks, the economy is contracting.

PhaseWhat is happeningHow a business might respond
ExpansionGDP grows, jobs are plentiful, people spend moreHire staff, add products, open a new location
PeakActivity is at its highest; prices often rise quicklyBuild up savings, avoid taking on too much debt
Contraction (recession)GDP falls, layoffs rise, people cut back on wantsCut costs, focus on best-selling products, offer value deals
TroughThe lowest point; unemployment is highestProtect cash, keep loyal customers, plan for recovery
RecoveryGDP starts growing again, hiring returnsRehire, restock, invest carefully in growth
A recession is a contraction that lasts a while (a common rule of thumb is two quarters in a row of falling GDP). Needs like groceries hold up better than wants in a recession.

Inflation and interest rates

Inflation is a general rise in prices over time, which means each dollar buys less. If a basket of groceries cost $200 last year and the same basket costs $206 this year, prices rose by $6, and . An interest rate is the price of borrowing money, shown as a percentage per year. A business that borrows $10,000 for one year at 5% interest pays in interest.

The Bank of Canada is Canada's central bank. It aims to keep inflation low and steady, with a target of 2% a year. Its main tool is its policy interest rate, which affects the interest rates banks charge on loans and mortgages. When inflation is too high, the Bank of Canada raises its policy rate. Borrowing becomes more expensive, so people and businesses borrow and spend less, and price increases slow down. When the economy is weak, the Bank lowers its policy rate, making borrowing cheaper to encourage spending and hiring.

ABank of Canada raises its rate
  • Loans and mortgages cost more
  • People and businesses borrow and spend less
  • Slows inflation
  • A business may delay buying new equipment
BBank of Canada lowers its rate
  • Loans and mortgages cost less
  • People and businesses borrow and spend more
  • Helps a weak economy grow
  • A good time for a business to borrow to expand

When market forces hit people they cannot control

Market forces are the pressures of supply, demand and competition that move prices and jobs. Many groups in Canada have been affected by these forces through no fault of their own. When a large factory in a one-industry town closes because its products can be made more cheaply elsewhere, hundreds of workers lose jobs at once, and local shops and restaurants lose customers too. Farmers can lose a year's income when a drought cuts their crop or when the world price of what they grow suddenly drops. Small, independent retailers have struggled to compete with large online sellers that offer low prices and fast delivery. Communities whose jobs depend on natural resources, including many First Nations, Métis and Inuit communities near mines, forests or oil and gas projects, can see work and revenue rise and fall as world resource prices swing up and down. None of these groups caused the change. Common responses include retraining programs for laid-off workers, employment insurance, crop insurance for farmers, small shops moving online or competing on personal service, and communities building a wider mix of local businesses so one industry is not everything.

The four market structures

A market structure describes how many businesses compete in a market and how different their products are. The fewer the competitors, the more control a business has over its price. Market share is the percentage of all sales in a market that one business makes: A business with a large market share has more power to set prices.

Worked examples

Reveal one step at a time and try to beat it to the next line.

Example 1
A sporting-goods store notices that layoffs are rising, customers are buying fewer bikes and kayaks, and sales of basic running shoes are steady. Which phase of the business cycle is this, and what should the store do?
Example 2
A bakery owner wants to borrow $20,000 for one year to buy a new oven. The bank's rate was 4%, but after the Bank of Canada raised its policy rate the bank now charges 6%. How much more interest will the owner pay?
Example 3
A town has four grocery stores with total yearly sales of $40,000,000. Store A sells $14,000,000. Find Store A's market share, and name the market structure if only these four stores serve the town.

Where marks get lost

  • Putting the phases in the wrong order. After a peak comes contraction, then the trough, then recovery and expansion.
  • Thinking the Bank of Canada raises interest rates to help the economy grow. Raising rates slows spending to fight inflation; lowering rates encourages growth.
  • Calling any big company a monopoly. A monopoly has only one seller with no close substitute; a few big firms is an oligopoly.
  • Blaming workers or farmers for job losses caused by market forces beyond their control, such as world prices, new technology or weather.
  • Calculating inflation by dividing by the new price instead of the old price.
