Learning Outcomes
1. Describe the business cycle & its primary phases.2. Illustrate how unemployment is measured & explain
different types of unemployment.3. Explain how inflation is measured & distinguish
between cost-push inflation & demand-pull inflation.4. Relate how unanticipated inflation can redistribute
real income5. Discuss how inflation may affect the economy’s
output level
27-3
• Alternating increases and decreases in economic activity over time
• 4 phases of the business cycle• Peak - when biz xtvt reaches a temporary max with full
(100%) employment and near-capacity output• Recession - a decline in Y, I, Empl, & trade lasting 6
months or more; aka ‘economic contraction’• Trough - the bottom of the recession period • Expansion - when output and employment are
recovering and expanding toward the full employment level.

The Business Cycle
LO1
27-7
• Malaysia’s long-run growth has many interruptions (normal).• Aka ‘uneven growth’• When there is rapid growth, normally we will have inflation. • When there is recession / depression , we’ll have decline in
employment & output.• Business cycle fluctuations
• Economic shocks• Prices are “sticky” downwards• Economic response entails decreases in output and
employment
The Business Cycle
LO1
27-8
Normally, high growth, high inflation
27-9
27-10
• Economic shocks are unexpected events.• Cause trouble for us (indv + firm) to adjust.• Prices can be inflexible downwards• if total spending decline fast & firms cannot lower
prices, the firms will end up selling fewer units of output.
27-11
• The “sticky” prices (price that is hard to change) result in slower sales
• consequently will cause firms to cut back on production; • --> GDP to fall.• Then employment will fall (due to fall in demand)• Then economic contraction• Inflexible prices are said (blaimed) to be a major factor in
preventing the economy from quickly adjusting to economic shocks. These shocks are outlined on the next slide.
27-12
Causation: A First Glance
• Causes of shocks• Irregular innovation• Productivity changes• Monetary factors• Political events• Financial instability
• Recession of 2007
LO1
27-13
Cyclical Impact (what happen if country is going through recession period)
• The Durable goods (expected life >3 years) affected most• Capital goods• Consumer durables
• Nondurable consumer goods affected less• Services• Food and clothing

Unemployment

(88.3 million)
Employed(142.5 million)
Unemployed(12.5 million)
Total population (314.9 million)

Unemployment rate =

X 100 = 8.0%
Unemployment rate = # of unemployed labor force

LO2
27-15
Unemployment
• Criticisms of unemployment (causing official report to understate actual unemployment)
• Involuntary part-time workers counted as full-time
• Discouraged workers are not counted as unemployed (nak kerja, tapi tak mencari secara active)
LO2
27-16
• Frictional unemployment• Individuals searching for jobs or waiting to take
jobs soon (grads)• Structural unemployment
• Occurs due to changes in the structure of the demand for labor (from MAS to AirAsia)
• Cyclical unemployment• Caused by the recession phase of the business
cycle (Shell)
Types of Unemployment
LO2
27-17
Definition of Full Employment
• Full employment ≠ 0 unemployment• Full employment ≠ 0 cyclical unemployment• Aka Natural Rate of Unemployment (NRU)
• Full employment level of unemployment• Can vary over time
• Demographic changes• Changing job search methods• Public policy changes
• Actual unemployment can be above or fall below the NRU
LO2
27-18
Economic Cost of Unemployment(How much does a country ‘loss’ if there’s high
unemployment)
• GDP Gap• GDP gap = actual GDP – potential GDP• Can be negative or positive
• Okun’s Law• Every 1% of cyclical unemployment creates a
2% GDP gap
Country is underproduced, inefficient

Noneconomic Costs(the side effect of being
unemployed)
• Loss of skills and loss of self-respect• Plummeting morale• Family disintegration• Poverty and reduced hope• Heightened racial and ethnic tensions• Suicide, homicide, fatal heart attacks, mental
illness• Can lead to violent social and political change

Inflation
• General rise in the price level• Inflation reduces the “purchasing power” of money• Consumer Price Index (CPI)

27-29
2 Types of Inflation
• Demand-Pull inflation, happens when• Excess spending relative to output (S > Y)• Central bank issues too much money• “too much spending chasing too few goods”
• Cost-Push inflation, happens when• per-unit input costs increases, but output falls.• As a result, economy’s supply decline, • supply shocks
LO3
27-30
2 Types of Inflation
• Cost-Push inflation, happens when• Lets say wage rate increase, or oil price increases• per-unit input costs increases, but output falls.• Rising cost reduce profit, • Rising cost reduce amount of supply,• As a result, economy’s supply decline, • supply shocks• And price level increases; inflation
HOW TO SOLVE ?
LO3
27-31
27-32
Inflation• Difficult to distinguish the causes of inflation types• Types differ in sustainability
• Demand-pull continues as long as the excess spending continues (eg: if Malaysians continue to shop regardless of their declining income)
• Cost-push ends in a recession (during recession, less spending)
LO3
27-33
Redistribution Effects of Inflation
• Nominal income• Unadjusted for inflation• The one u see in report/news
• Real income – refers to purchasing power of income.• (how much u can actually purchase with ur income)
• Nominal income adjusted for inflation• Anticipated vs. unanticipated income
Percentagechange in real income =
Percentage change in nominal income
Percentage change inprice level
LO4

27-35
Who is Hurt by Inflation?
• Fixed-income receivers• Real incomes fall
• Savers• Value of accumulated savings deteriorates
• Creditors• Lenders get paid back in “cheaper dollars”
LO4
27-36
Who is Unaffected by Inflation?
• Flexible-income receivers• COLAs (CosT OF Living adjustments)• Social Security (PERKESO) recipients• Union members
• Debtors• Pay back the loan with “cheaper dollars”
LO4
27-37
Anticipated Inflation• If inflation is anticipated, individuals can plan ahead mitigating the effects of inflation.
• “Inflation premium” is the amount that the interest rate is raised to cover effects of anticipated inflation.
• “Real interest rate” is defined as the nominal rate minus the inflation premium.
• Real interest rate• Rates adjusted for inflation
• Nominal interest rate• Rates not adjusted for inflation

Other Redistribution Issues
• Deflation (a decrease in the general price level of goods and services)
• Mixed effects• Incomes may rise• Fixed assets values may fall• For fixed-rate mortgages, real debt declines
• Arbitrariness

Hyperinflation
• Extraordinarily rapid inflation• Devastates an economy• Businesses don’t know what to charge• Consumers don’t know what to pay• Money becomes worthless• Zimbabwe’s 14.9 billion percent inflation in
