Section 3: Economic Fluctuations

Section 3: Economic Fluctuations

Most economies exhibit positive long-run growth in output (in the UK we are used to GDP growth of 2-3% per annum). However, most economies also experience strong short-term fluctuations in output, employment, investment, wages and interest rates. The 2009/10 UK recession was one such downturn in the economy. This section builds on the model of economic growth developed in the previous section and seeks to understand what causes short-term fluctuations, and why employment, unemployment, wages and interest rates fluctuate along with GDP.
