ECM B06: Course Plan
Short-Run (SR) The SR is such a short period of time that prices are fixed. [The
technology is also fixed as is the productive capital stock.
Variations in employment (L) lead to changes in output (Y).]
Long-Run (LR)
The LR is a long enough period of time that all prices are
perfectly flexible. At the same time it is a short enough period
of time that the productive technology and capital stock
continue to be fixed.
Very Long-Run The very long-run is such a long period of time that not only are
all prices perfectly flexible but all inputs (K & L) and the
productive technology can vary as well.

Chapter 2 deals with measurement issues. How do you measure aggregate
output (real or nominal), the average price level and the rate of inflation.
These issues overlap all of the modelling chapters to follow.
•
When dealing with practise questions think of what chapter material (or
model) applies and what is exogenous (given) and endogenous (to be
determined).
