Wage and price stickiness Select one: a. gives rise to a vertical long-run aggregate supply curve. b. gives rise to a vertical short-run aggregate supply curve. c. creates a surplus or a shortage of real GDP. d. prevents the economy from producing its potential level of real GDP.

d. prevents the economy from producing its potential level of real GDP.

Explanation:

Price-stickiness or Wage-stickiness, is a term that describes a condition in which a nominal price or wage is resistant to change. Often referred to as Nominal Rigidity, this occurs when a price or wage is fixed in nominal terms for a given period of time.

In other words, Price stickiness or Wage Stickiness occurs when workers' earnings or price don't adjust quickly to changes in labor market conditions, thereby creating sustained periods of shortage or surplus.

Hence, Price and Wage stickiness prevent the economy from achieving its natural level of employment and its potential output, which in turn prevents the economy from producing its potential level of real GDP.

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
