Practise using AD/AS diagrams, components and shifts to analyse output, price levels, growth and inflation pressures.
What is a correct description of an aggregate demand (AD) curve?
It is a curve obtained by adding the market demand curves of all consumer goods traded in an economy.
It is a curve determined by the horizontal summation of all individual consumer demand curves for a product.
It is a curve that shows the total amount of goods and services firms are willing to buy at a given price in an economy.
It is a curve that shows the total demand of all goods and services produced at all price levels in an economy.
A government succeeds in changing a current account deficit into a current account surplus.
Why might this current account surplus increase the country's inflation rate?
It raises Aggregate Demand.
It raises production costs.
It reduces the exchange rate.
It reduces the money supply.
Why would a fall in a country's average price level cause its aggregate demand curve to slope downwards?
It leads to an increase in interest rates.
It reduces the real value of money balances.
It makes the country's goods cheaper relative to foreign goods.
It leads to the expectation of further price falls.
The diagram shows a shift in the Aggregate Demand curve, from to .
What might have caused this shift?
a fall in the budget surplus
a fall in the trade surplus
a rise in imports
a rise in the interest rate
What is both a valid statement and consistent with the features of the diagram?
AS cannot be increased beyond some level of real output.
Consumption is a component of AD and is lower when the general level of prices is lower.
Investment is a component of AS and is independent of the general level of prices.
The greater the demand for a country's exports, the lower will be AD.
The diagram shows the aggregate demand (AD) and aggregate supply (AS) for an economy.
Which changes in subsidies and indirect taxes would have caused the change from to ?
higher subsidies and higher indirect taxes
higher subsidies and lower indirect taxes
lower subsidies and higher indirect taxes
lower subsidies and lower indirect taxes
Explain, with the help of a diagram, the difference between what causes (i) a movement along an aggregate supply curve and (ii) a shift in an aggregate supply curve.
