(b) Decrease in technology

(c) Depreciation of the real exchange rate

Solutions

Expert Solution

At any given point in time, the aggregate demand (AD) is defined as a sum of consumption demand, investment demand, government spending and net exports.

(a) Increase in consumer confidence

An increase in consumer confidence will result in a greater consumer spending now as they have good outlook about the economy. Hence, it will increase the aggregate demand of a country at a given point in time.

(b) Decrease in technology
This affects only the Aggregate Supply of the economy. Hence there will be no change in the aggregate demand of a country.

(c) Depreciation of the real exchange rate
A Depreciation of the real exchange rate implies that the domestic currency becomes relatively cheaper than foreign currency. Note that exchange rate is the price of a currency in terms of a foreign currency. A cheaper domestic currency implies that domestic goods will become cheaper relative to foreign goods. Hence the aggregate demand will increase as net exports will increase.
