Many economists view the natural rate of unemployment as the level observed when real GDP is given by the position of the long-run aggregate supply curve. There can be positive unemployment in this situation because

question
In Ciudad Barrios, El Salvador, the latest payments from relatives working in the United States have finally arrived. When the credit unions open for business, up to 150 people are already waiting in line. After receiving the funds their relatives have transmitted to these institutions, customers go off to outdoor markets to stock up on food or clothing or to appliance stores to purchase new stereos or televisions. Similar scenes occur throughout the developing world, as each year migrants working in higher-income, developed nations send around $200 billion of their earnings back to their relatives in less developed nations. Evidence indicates that the relatives, such as those in Ciudad Barrios, typically spend nearly all of the funds on current consumption.
Based on the above information, developing countries' income inflows transmitted by migrant workers are primarily affecting their economies' long-run aggregate _____ curves.
answer
demand
question
The equilibrium price levels in nations that are recipients of large inflows of funds from migrants will likely
answer
rise because there is an increase in the aggregate demand in these countries.
question
Long-run equilibrium in the economy will occur
answer
at the price level where total planned real expenditures equals real GDP at full employment.
question

answer
where the long-run aggregate supply curve meets the aggregate demand curve.
question

question
A persistent decline in the price level due to economic growth with stable aggregate demand is
answer
secular deflation
question
In the long run, persistent deflation in a growing economy can occur if
answer

question
An increase in the LRAS curve that is larger proportionately than an increase in the AD curve will lead to

question
If the actual price level increases beyond the long-run equilibrium price level, all of the following will tend to occur except
