"Demand provided through a government mandate" is Government Purchases. It increases Aggregate Demand. When aggregate demand increases, the point at which the Aggregate Demand curve and the Short Run Aggregate Supply Curves intersect shifts up and to the right, possibly causing an increase in prices, an increase in output, or an increase in both, depending on whether or not we are in a recession.
View attachment 67142630 On this graph, the shift in aggregate demand caused a moderate shift in prices and a moderate increase in real Gross Domestic Output. That is because the equilibrium point is the intersection of all three graphs (Long Range Aggregate Supply, Short Range Aggregate Supply, and Aggregate Demand). Our economy's current equilibrium point is currently much farther to the left on the Short Range Aggregate Supply graph, and as such an increase in Aggregate Demand will shift the equilibrium closer to the Long Range Aggregate Supply,
which is exactly the point of Government Stimulus Spending. Government transfer payments (Social Security, Food Stamps, Welfare, etc.) work in a similar way, except instead of increasing Aggregate Demand through Government Purchases, they increase consumers' consumption.
Now, is a raise in the minimum wage a transfer payment or a government purchase? TRICK QUESTION! It's neither. A rise in the minimum wage will cause a shift in Aggregate Demand to the right (as consumers' incomes rise) and a slight leftward shift of Short Run Aggregate Supply, bringing the economy's equilibrium point closer to Long Range Aggregate Supply.
