Types of Indicators
Leading, Coincident, Lagging
Coincident indicators are indicators which ocurrs at the same time as the economic activity.
Example:
- Payroll
- Personal income less transfer payments
Leading indicators are economic indicators which tend to change before the general economic activity.
Example:
- Stock prices
- Average work hours in manufacturing sector
Lagging indicators tail behind the general economic activity.
Example:
- Unemployment rate
- Percentage change in CPI
The time difference between the indicator and the economic activity is called lead time or lag time.
Correlation
An indicator can also move in the same or opposite direction of the general economic activity. Pro-cyclical indicators move in the same direction as the general economic activity. Counter-cyclical indicators move in the inverse direction of the general economic activity. Unemployment is an example of a counter-cyclical indicator. Statistically, correlation can be used to determine whether an indicator is pro- or counter-cyclical.
