1. A rising household saving ratio combined with an external deficit that is draining aggregate demand, doesn't necessarily mean that the budget deficit has to rise to maintain current output growth.

2. Assume that total employment grew in a particular month in net terms yet unemployment still rose. You also know that the labour force participation rate fell marginally. Taken together this information tells you that:

Labour force growth outstripped employment growth but was less than the growth in the working age population.
The working age population grew faster than employment and offset the decline in the labour force arising from the drop in the participation rate.
The labour force grew faster than employment but you cannot tell what happened to the working age population from the information provided.

3. If the European Monetary Union (Eurozone) relaxed the budget restrictions on national governments that are applicable under the Stability and Growth Pact (3 per cent deficit to GDP ratios and 60 per cent public debt to GDP ratios) then the current solvency risk facing several EMU members would be resolved.

4. The Greek crisis could significantly ease its current crisis if it improved its capacity to tax its higher income earning groups.

5. Premium question: Mainstream economists have argued that the large scale quantitative easing conducted by central banks in recent years - so-called printing money - would be inflationary. They base their predictions on the Quantity Theory of Money which links the growth of the money stock to the inflation rate (too much money chasing too few goods). The fact that inflation has not accelerated sharply indicates that this mainstream economic theory should be discarded.
