Answer:
A 2.9% pay increase in 2014 for U.S. workers will cause the AS (aggregate supply) curve to shift inward in the short-run, signaling a decline in the quantity supplied.
Step-by-step explanation:
The supply quantity declines because a pay increase increases suppliers' cost of production and reduces their ability to produce more goods and services. On the contrary, a fall in workers' pay causes the aggregate supply curve to shift outward, thereby increasing the quantity supplied. In the long-run, the pay increase will increase aggregate demand, thereby pushing prices to increase, while, at the same, suppliers try to increase the quantity supplied to meet with increased prices and demand.
