The 2016-17 budget isn't really a budget for "jobs and growth". It's more of a political budget than an economic budget. If you actually analyse the measures that the budget proposes they have no real economic impact. I'll try and help out by discussing some of the big policies.
Ten Year Enterprise plan
The plan to cut company tax down to 25% will not go past the senate. The goal is not aggressive enough as well even though it will slightly make Aus. firms more internationally competitive. Economic modelling shows that in the long run (20 years) economic growth will only increase by 1% of GDP (which is pretty much negligible). Also most of the benefits of cutting company tax will go to overseas investors. Theoretically cutting company tax is meant to improve productivity, allowing profits to be reinvested into capital, training etc. but in practice that is not the case. Improvements in unemployment and productivity will also be negligible. However the tax cuts to small businesses to 27.5% will be slightly beneficial.
Income tax Cuts
Tax cuts will only affect the top 25% of income earners and will no nothing for low income earners. This will increase the level of income inequality in the nation. Also the tax cuts will only generate a meagre 6$ a week for those affected so once again an ineffective policy.
Superannuation tax concession reductions
This policy makes the situation less unfair. During the mining boom, the government was raking in so much money that they started handing out tax cuts to the rich (to get votes) and it has become a structural issue ever since. These super changes will work with the Low Income Superannuation Tax Offset policy to make income distribution as a result of superannuation less unfair. However the government's decision to increase the excise tax by 50% over the next 4 years is a regressive policy which will ultimately negate improvements to income equity.
Prepare Trial Hire
This policy intends to increase workforce participation and also improve the skills and quality of the workforce by providing unemployed youth vocational training or work placements. In theory this would work as the unemployed and the young have opportunities to garner experience and develop skills which can improve their human capital and employability. (targeting the issue of structural unemployment) however in practice, the policy distorts the labour market. The reason being is that employers might choose to higher "interns" over actual paid workers.
Infrastructure spending
50 bill to be spent on infrastructure over the next few years (forgot how many). In theory infrastructure spending is good. Who doesn't love infrastructure spending. Improvements in productivity, productive capacity, employment, economic growth!! But in reality, the government's projects when analysed by an external organisation (something Institute) are actually ineffective projects that will not do much to improve the level of productivity in the economy.
Overall the budget pretty much sucks and lacks major economic reform.
Defense Spending
