Output gaps

The output gap is the difference between the actual level of national output and its potential level and is usually expressed as a percentage of the level of potential output. In this revision article we link the output gap to aspects of macroeconomic performance.

Uncertainty about future levels of demand is nearly always the main factor driving investment decisions - hence the risk of a negative accelerator effect during an economic slowdown or recession.

Trend growth

This revision note looks at trend or long term growth in an economy. The trend rate of growth is the long run average rate for a country over a period of time. Measuring the trend requires a long-run series of data to identify the different stages of the economic cycle and then calculate average growth rates from peak to peak or trough to trough.
