About This Topic

Fiscal policy is the use of government spending and taxation to influence the economy. In Grade 9, students explore how the Canadian federal and provincial governments make decisions about where to spend money, such as on healthcare, infrastructure, or education, and how to collect it through various taxes. This topic is central to understanding the political debates in Canada, as different parties have different views on the 'right' level of government involvement in the economy.

Students learn about the concepts of budget surpluses, deficits, and the national debt. They also examine 'expansionary' fiscal policy (spending more or taxing less to boost the economy) and 'contractionary' fiscal policy (spending less or taxing more to slow down inflation). This topic is particularly effective when students engage in budget simulations, where they must make the same difficult choices as the Minister of Finance, balancing the needs of different groups while trying to keep the economy stable. This hands-on approach reveals the political and economic trade-offs that are often oversimplified in the news.

Key Questions

  1. Explain how inflation erodes the purchasing power of money.
  2. Analyze the causes of demand-pull versus cost-push inflation.
  3. Predict the impact of unexpected inflation on different economic groups.

Learning Objectives

  • Calculate the annual inflation rate using historical Consumer Price Index (CPI) data.
  • Analyze the primary causes of both demand-pull and cost-push inflation in the Canadian context.
  • Evaluate the impact of unexpected inflation on the purchasing power of fixed-income earners and borrowers.
  • Compare the measurement of inflation using the CPI versus other potential price indexes.

Before You Start

Supply and Demand

Why: Understanding how shifts in supply and demand influence prices is fundamental to grasping the causes of inflation.

Basic Economic Concepts: Goods, Services, and Prices

Why: Students need a foundational understanding of what prices represent in an economy to comprehend how changes in price levels affect purchasing power.

Key Vocabulary

InflationA sustained increase in the general price level of goods and services in an economy over a period of time, leading to a fall in the purchasing value of money.
Consumer Price Index (CPI)A measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care, used to calculate inflation.
Purchasing PowerThe value of a currency expressed in terms of the amount of goods or services that one unit of money can buy. Inflation erodes purchasing power.
Demand-Pull InflationInflation that occurs when overall demand for goods and services in an economy increases faster than the economy's production capacity.
Cost-Push InflationInflation that occurs when the cost of producing goods and services increases, leading businesses to raise prices.

Watch Out for These Misconceptions

Common MisconceptionThe national debt is just like a family's credit card debt.

What to Teach Instead

While both involve owing money, a government can print its own currency and has a much longer lifespan than a person. A class discussion on 'sovereign debt' helps students see that while debt matters, the rules for a country are different than for a household.

Common MisconceptionTax cuts always pay for themselves by growing the economy.

What to Teach Instead

This is a debated theory. In reality, tax cuts often lead to lower government revenue and higher deficits unless spending is also cut. A simulation where students 'lose' services after a tax cut helps them see the direct trade-off.

Real-World Connections

  • The Bank of Canada uses the CPI to set its target for inflation, influencing interest rates that affect mortgage payments for homeowners in Toronto and car loan rates for consumers nationwide.
  • Statistics Canada collects data on prices for thousands of goods and services across the country to construct the monthly CPI, impacting government decisions on Old Age Security payments and tax brackets.
  • Retirees living on fixed pensions in rural Manitoba may experience a greater reduction in their standard of living during periods of high inflation compared to those with variable income sources.

Assessment Ideas

Quick Check

Present students with a scenario: 'The price of gasoline increased by 20% and the price of milk increased by 10%. If these are the only two goods, and consumers spend 40% on gasoline and 60% on milk, what is the overall percentage increase in prices?' Ask students to show their calculations.

Discussion Prompt

Facilitate a class discussion using the prompt: 'Imagine you are saving for a down payment on a house in Vancouver. How would unexpected inflation, say 8% per year, affect your savings goal compared to a year with 2% inflation?' Encourage students to consider the time value of money.

Exit Ticket

On an index card, ask students to define one type of inflation (demand-pull or cost-push) in their own words and provide one real-world example of a factor that could cause it in Canada.

Frequently Asked Questions

What is the difference between a deficit and the debt?
A deficit is the shortfall in a single year when the government spends more than it collects in taxes. The national debt is the total accumulation of all those yearly deficits over time. Think of the deficit as a single monthly credit card bill and the debt as the total balance on the card.
How can active learning help students understand fiscal policy?
Fiscal policy is about choices and trade-offs. By putting students in the role of the decision-maker in a budget simulation, they move from being passive critics to active problem-solvers. They realize that you can't fund everything and that every tax cut has a corresponding 'cost' in terms of public services.
What is 'expansionary' fiscal policy?
This is when the government tries to 'expand' the economy, usually during a recession. They do this by increasing spending (like building bridges) or cutting taxes to put more money in people's pockets. Students can research how Canada used this during the 2008 financial crisis or the COVID-19 pandemic.
Who pays the most tax in Canada?
Canada has a progressive income tax system, meaning people with higher incomes pay a higher percentage of their earnings in tax. However, there are also 'regressive' taxes like the HST, which take a larger percentage of income from lower-earning people because they spend more of their total income on taxable goods.
