The following image shows the initial long-run aggregate supply curve (LRAS) and short-run aggregate supply curve (SRAS), the aggregate demand (AD) curve, and shifts in the LRAS and SRAS curves in an economy. Suppose there is an adverse supply shock. Which of the following shifts in SRAS and LRAS are likely to happen?
An adverse supply shock shifts both SRAS and LRAS curves to the left. SRAS shifts to SRAS1 and LRAS shifts to LRAS1.
Which of the following would most likely cause an adverse long-run aggregate supply shock and stagflation?
An oil embargo that significantly reduces oil supply to all industrialized countries. most likely cause an adverse long-run aggregate supply shock and stagflation.
Which of the following statements is true?
Closing an expansionary gap involves inflation and closing a recessionary gap involves deflation.
Which of the following correctly describes a long-run equilibrium?
In the long run equilibrium, aggregate demand equals aggregate supply.
Which of the following increases an economy's potential output?
Institutional changes with defined property rights.
Which of the following is the most likely result of a recessionary gap?

Latasha and her employer both expected inflation to be 3% between 2012 and 2013, so they agreed, in a two-year contract, that she would earn $12.00 per hour in 2012 and $12.36 per hour in 2013. However, suppose inflation between 2012 and 2013 actually turned out to be 6%, not 3%. For example, suppose the price of orange juice rose from $2.40 per gallon to $2.54 per gallon. This means that between 2012 and 2013, Latasha's nominal wageincreased by 3% , and her real wagedecreased by approximately3% .

Which of the following are assumed to remain unchanged along a given short-run aggregate supply curve? Check all that apply.
Real GDP The price level
Which of the following is a reason for the short-run aggregate supply curve of an economy becoming steeper as output increases?
Resources in the economy become scarcer as output increases.
The following image shows the initial long-run aggregate supply curve (LRAS) and short-run aggregate supply curve (SRAS), the aggregate demand (AD) curve, and shifts in the LRAS and SRAS curves in an economy. Suppose there is a technological breakthrough in the economy that makes production more efficient. Which of the following shifts in SRAS and LRAS would result in this scenario?
SRAS shifts to SRAS2 and LRAS shifts to LRAS2.
Which of the following correctly describes an economy's potential output level?
The maximum output level that is sustainable, given available resources, technology, institutional constraints, and production incentives.
The term potential output refers to
