Answer:
Oceania will have to take some other decisions like cutting taxes, subsidizing machinery, etc. since there's no investment tax credit
Step-by-step explanation:
Instruments like Investment Tax Credit is a tax used to help to finance the expansion of a sector. Like Solar energy ITC in America.
Since Oceania is a small country, with an open economy, and all other foreign countries do and Oceania does not, then it will be at a disadvantage.
Moreover, this small economy will have to take some other decisions on its economy like cutting taxes for some economy sectors which is desirable, subsidizing machinery, and so on.
