There is a large variety of problems that are at the core of this crisis, ranging from political to structural problems, but also including demand aspects. From the point of view of macroeconomic theory it should come as no surprise that economic dynamics – and especially investments – are influenced by both supply-side and demandside factors.
It is unlikely, though, that a pick-up in resources exports, as important as that will be, will be enough to keep overall growth on the right track. It will be helpful if some of the other areas of domestic demand that have been subdued start to grow faster.
