Overview of Topic
What is the future path of Canada’s
Business Cycle? Is Canada’s
economy currently contracting?
Economic Theory Data & MethodsOverview SummaryResults Application
In the News
Economic Theory Data & MethodsOverview SummaryResults Application
OECD warns of worst recession since early 1980sOECD says developed world could face worst recession since early 1980s; warns of
deflation
Economic contraction in Canada will be short-lived: Royal Bank
U.S. economic woes not necessarily Canada's fate
Business Cycles
Business cycle: “fluctuations of aggregate economic activity”, which consists of 4 stages: contraction, trough,
expansion & peak
Economic Theory Data & MethodsOverview SummaryResults Application
Peak
Trough
Business Cycles: Burns & Mitchell
Economic Theory Data & MethodsOverview SummaryResults Application
Business Cycles are recurrent, but not
periodic
Factors that affect
business cycles have regular patterns of
behavior
Theory suggests an
ARIMA model would not be
suitable
ARIMA & GDP’s Growth Path
Economic Theory Data & MethodsOverview SummaryResults Application
Classes of Economic Variables
Economic Theory Data & MethodsOverview SummaryResults Application
LaggingCoincidentLeading
Variable’s turning
point occurs before
the business cycle
Variable’s turning
point occurs at
the same time as
the business cycle
Variable’s turning
point occurs after
the business cycle
Theory suggests the appropriate lag length of different variables
Classes of Economic Variables
Economic Theory Data & MethodsOverview SummaryResults Application
CountercyclicalAcyclicalProcyclical
Variable moves in
the same direction
as the business
cycle
Variable does not
move with the
business cycle
(e.g. real interest
rates)
Variable moves in
the opposite
direction as the
business cycle
Theory suggests the coefficient sign of different variables
Considered Variables
Economic Theory Data & MethodsOverview SummaryResults Application
GDP= C + I + G + NX
•Durable consumption
• Stock index prices
•Capital Investment • Trade Balance
• CA Balance
•Exchange rates
•Government Spending on G&S
Other considered Variables: Bank of Canada Interest rate, Labour productivity, inflation (CPI), unemployment, MB1, mortgage rates
What period should be used?
• 1996:1 to 2006:1
• Allows for a hold-out period
• Uses data that best matches the current structural relationship between the independent variables and the dependent variable

Review of Parameter Signs
Economic Theory Data & MethodsOverview SummaryResults Application
Variable Sign Reasoning
d_labour + Labour is better utilized in a period of economic prosperity
d_industrialprod_1 + Firms produce more when the economic outlook is good
d_exchange_1 -Canada is a net export country; as the change in the exchange rate falls, Canadian exports become more
attractive
d_kinvestment_1 + Firms invest more when the economic outlook of Canada is good

Sensitivity Analysis
1. What if the future values of the independent variables were less volatile than expected?
2. What if government successfully increase capital investment?
