As one of the commissioners in the Economic Planning Commission of a country, you realised that there are always conflicts between the commissioners and the new parliamentarians regarding the delays in realising the impact of a policy by communities. This implies that by the time the policy measures become effective, circumstances may have changed to such an extent that the measures may even have a destabilising effect. On behalf of the planning commission, you were requested to give a brief to the parliament on the difficulties associated with attempts to stabilise the economy using macroeconomic policy, with a focus on policy lags. As part of your presentation, discuss the four different types of policy lags in an economy (one paragraph per lag). In each lag, discuss how the duration of each lag differs for monetary and fiscal policy? (25 Marks)
