Comprised of tax revenues and government expenditure
33
How can the budget deficits be financed?
``` By borrowing Austerity measures Taxes increased - too high discourage Caps to amount of welfare benefits Harsher rules on tax - tax avoidance Less government spending Promote economic growth Default the debt ```
34
Discretionary fiscal policy, and how can it improve macroeconomic performance
Involves deliberate changes in government expenditure and taxes with the intention of influencing aggregate demand Change the amount of spending and taxation to stimulate the economy Government can influence the size of the circular flow by changing the government budget, and spending and taxes in areas which need stimulating
35
Expansionary fiscal policy | Deflationary fiscal policy
Aims to increase AD, governments increase spending or reduce taxes to do this, it leads to worsening of the government budget deficit and it means governments have to borrow more to finance this. Aims to decrease AD, governments cut spending or raise taxes which reduces consumer spending, leads to improvement of the government budget deficit
36
Limitations of fiscal policy
Governments might have imperfect information - inefficient spending Time lag Crowding out in the private sector Difficulties paying back how much the government spend- debt
37
Monetary policy
Used by the government to control the money flow of the economy, done with interest rates and quantitive easing, conducted by the BofE
38
Monetary policy - interest rates
Alters interest rates to control the supply of money Target 2% Bank controls base rate Lender of last resort
39
Quantitive easing
Help stimulate the economy when standard monetary policy is no longer effective Used when inflation is low Method to pump money directly into the economy Bank bought assets in the form of government bonds using the money they created, then used to buy bonds from investors increases amount of cash flowing into the financial system Encourages lending to firms and individuals, since cost of borrowing is lower Encourages more investment more spending and high growth, however could be high inflation
40
Limitations of monetary policy
Banks might not pass base rate onto consumers Consumers might be unable to borrow because banks are unwilling to lend Interest rates will be more effective at stimulating spending and investment when cc is high
41
Liquidity trap
The supply of money meets the demand for money at P, Q. A rate of interest above P means the supply of money exceeds demand, this causes rate of interest to fall, the interest rate remains at equilibrium unless there the demand for or supply of money changes, A shift in supply of money to the right show a liquidity trap, this is when a change in the supply of money does not change the interest rate, monetary policy cannot be used to influence consumption and investment
42
Asymmetric information
Information failure | When one party to an economic transaction possesses greater material knowledge than the other party
43
Moral hazards
Situation where there is a risk that the borrower does things that the lender would not deem desirable, because it makes the borrower less likely to repay the loan

45
Causes of exchange rates
``` Inflation Interest rates Speculation Other currencies Government finances Balance of payments International competitiveness Government intervention ```
46
J CURVE
Occurs when currency is devalued, as imports are more expensive, at first total value of imports increase which worsens the deficit Value of exports decreases reduction in the trade deficit Time lag in changing the volume of exports and imports Due to trade contacts and price inelasticity of demand for imports in the short run
47
Advantages and disadvantages of policies which hold exchange rates artificially above or below their free market levels
When firms know what value the currency is relative to another currency, it allows them to plan investment Monetary policy focused target to work towards Balance of payments should not automatically adjust to economic shocks
