The causes of shifts in the market supply curve for labour
Several factors can increase or decrease the total number of workers available in an occupation at every wage rate. When these factors change, the entire labour supply curve shifts left or right.
Real World
When the UK expanded free nursing degree apprenticeships in 2020, removing tuition costs, the number of people entering nursing training rose significantly — a rightward shift in labour supply with no wage change.
Exam Focus
Distinguish clearly between a movement along the curve (wage change) and a shift (non-wage factor); confusing the two loses marks.
