Chapter 6Booms, Recessions and Inflation

Annual percent change in Real GDP

The economy (real GDP) grows, but not steadily.In recessions, it shrinks (i.e., real GDP falls),and unemployment increases considerably.

Booms and Recessions(“Business Cycles”)

2

When real output falls (= recession) or its growth slows, the unemployment rate rises, sometimes sharply.

Why We Have Booms and Recessions

Due to fluctuations in aggregatedemand for goods & services.

(a) Investment Spending by Business

fluctuates considerably

(b) The “Multiplier Effect”which spreads fluctuationsin investment spending intoconsumption spending

(c) The “Accelerator Effect”which spreads trends inconsumption spending intoinvestment spending

(d) Fluctuations in Exportsthrough which internationalconditions spread into Canada

(a) The Instability of Business Investment Spending

Why does business investment spending fluctuate so much?

Business investment spending is influenced by

business confidence and interest rates,both of which can vary considerably from year to year.

Business investmentspending fluctuatesconsiderably from year to year.

In this example, the “multiplier” is 1.6.

Further “rounds”of increases inincomes andconsumer spending

A respending effect that magnifies the impact of a change in spending.

Initial increase ininvestmentspending:

+ $10 billion

Final/totalboost to

aggregatedemand & GDP:

+ $16 billion

The multiplier also works “in reverse” in recessions,when decreases in investment larger decreases in GDP.

(c) The Accelerator Effect

During a boom:If consumer spending

(= business’ sales) is rising

andbusinesses’ production

is at or near capacity

“Induced investment” (Ii) will increase sharply, to increase capacity to meet forecasted sales.

Induced investment cancollapse, because no need to increase capacity.

During a slowdown:If consumer spending

levels off

C rises Ii rises sharply

C levels off Ii falls sharply

The “Multiplier”(Text, p. 127-130)

+ The “Accelerator”(Text, p. 130-131)

+ Decreasing confidence of consumers & businesses less borrowing; money

supply depressed

falling aggregate demand can gain momentum

(d) Fluctuations in Exports

Exports amount to over 30% of aggregate demand in the Canadian economy, and about 7/10 of these exports go to the USA.

SO --World (especially U.S.) economic booms and recessions affectCanada, not only by causing Canada’s exports to fluctuate,

but also on the entire Canadian economy,through the “multiplier effect”.

Inflation/Peak

A Typical Business Cycle

Inflation and Interest Rates

Lender/investor earning 6% interest on a loan/investment of $100:

If the rate of inflation were 3%:Your interest income would be

While inflation would reduce thepurchasing power of your $100 by

$6

-3

For a net gain (before tax) of +$3

If the rate of inflation were 8%:Your interest income would be $6

While inflation would reduce thepurchasing power of your $100 by

For a net gain (before tax) of

-8

-$2(loss)

What could/would investors do about such losses due to inflation?

They would require higher interest rates.11% interest rate

Supply Side(potential output)

Demand Side(aggregate demand)

Aggregate demand begins to rise, due to:(a) backlogs of demand for “big-ticket” items(b) low interest rates

The Expansion (Boom) Phase

Aggregate demand gains momentum, due to:• Rising consumption & investment spending• The “multiplier effect”• The “accelerator effect”• “Boom psychology” ( borrowing rises)

Output & employmentrise rapidly

This has not been happening in the recovery from the 2008-09 recession.

The Economy in Recession

Falling aggregate demand, due to:• weak investment & consumption spending

• the “accelerator effect” (weak C I falls)

• the “multiplier effect” (falling I C falls)

• “recession psychology” less borrowing

Investment spending:

Like a gigantic “sales forecast”: consider past trends and probable futuredevelopments estimate next year’s spending in each sector.

Usually done for one year into the future.

Economic Forecasting

2. By using “Leading Indicators”

= statistics that generally:• move up before economic growth speeds up, and • move down before an economic slowdown or downturn.

For example:• Stock prices• Housing starts• Durable goods orders• Bank loans• Steel production

Used to obtain fairly short-term indications of economic trends; published monthly. Most attention is paid not to the level of the Indicator, but rather to trends and changes in it, in % terms. More rapid increases in the indicator indicate improvements in economic conditions, and vice-versa.

Update on the current economic situation

Read the Chapter 6 “Recent Developments” file on SLATE.

UPDATE ON THE CURRENT SITUATION

Unusual nature of 2002-07 U.S. Economic Boom:

Boom was led by extremely high spending by U.S.consumers, largely financed by borrowing, and usingtheir homes as collateral.

AND high demand for housing created a housing price“bubble”, which increased the ability of consumersto borrow even more against their homes.

AND when the boom ended, it was not because rising interest rates slowed the economy down – it was muchmore serious, and sudden.

Credit was very readily available and demand high, butthe rate of inflation remained low, and interest ratesremained unusually low.

A Price “Bubble” (eg – in real estate or stocks)

Price rises more buying,

etc., in a “spiral”

AND – the higher housing priceswent, the more homeowners couldborrow to spend on consumption.

Housingprice bubble 

Boom in consumer borrowing& spending 

Economic boom 

Banks, investment funds, pension funds, etc. invested heavily in “securitized” investments containing risky mortgages

If housing prices keep rising, all will be (or seem) well: (a) consumers can continue borrowing and spending more, &(b) risks due to “securitization” will not be apparent.

BUT – what if the housing bubble bursts and home prices FALL?

The part played by subprime mortgages and “securitized”investment assets containing risky subprime mortgages

15

When the demand for housing decreased and many subprimeborrowers defaulted on their payments and were foreclosed,

housing prices fell sharply (the bubble burst)

Consumer spending fell:(excessive debt, lesscollateral for borrowingand a huge decrease in confidence)

Many “securitized” investmentslost value, shaking lending institutions’ confidence in their assets and their future loans and investments.

THE CREDIT CRISISas lending institutionscurtailed lending

RECESSIONas aggregate demand fell Each made

the other worse

Consumers & Businesses

BanksNon-bank lenders

= source of 60%of lending in theU.S. economy

“Securitized” investments

Loans “bundled” into securities

Securities aresold to investors

The real lenders:Pension funds, mutual funds,banks, insurance companies, etc.

What happens if thesereal investors (lenders)lose confidence in those“securitized” investments?

“Credit crisis”,as many consumers& businesses cannotget loans.

Meanwhile, over in Canada …The credit crisis and recession spread from USA to other nations, especially Canada and China, as their exports to the USA fell.

And as economic conditions worsened,consumer andbusiness confidenceplunged, dragging Canadian consumerand business invest-ment spending down.

Male and Female Unemployment

Rates

Males 15 years & over

Males 15-24 years

Females 15 years & over

Patterns?

The recession hit male employment (especially young males) much harder than females.

Why?

The goods-producing industriesthat rely on export sales and were most seriously affected by the recession employ mostly men.Young men were most seriouslyaffected because they lackseniority.
