Supply Side Policies


Supply side economics came to the forefront in the early 1980’s, championed by the governments of Ronald Reagan in the United States and Margaret Thatcher in the United Kingdom.

However, the term supply-side was first coined in 1976 to describe economic policies designed to influence output and employment through their impact on the supply-side as opposed to the demand-side of the economy.

Thus, increased investment and productivity would lead to increased output in the economy. With this increased output the economy grows and unemployment goes down.

This will cause the shifting of long run aggregate supply (LRAS) to the right and a pushing out of the Production Possibility Frontier Curve (PPF) as demonstrated below.
