the government can implement a number of policies to reduce the severity of the CAD
1. it can budget for a surplus (fiscal policy) to prevent 'crowding out' the australian finance market to the private sector, thus the local private sector is not forced to look overseas for surplus capital resources; - remembering that net income outflow is the greatest contributor to the CAD
2. the government could increase the level of national savings by encouraging the popluation to save in bank accounts and superannuation plans through tax incentives, or force the population to save through compulsory superannuation
3. the government could encourage the production of elaborately transformed manufactures through microreforms such as those to the labour market, goverment enterprises, national competition policy: - remembering that 60% of australian exports are derived from primary industry (commodities), which are more prone to price fluctuation on internaitonal markets and are not value added
these are just a few that i can remember off the top of my head
