Question: Should there be restrictions on repatriation of foreign investment capital (such restrictions could prevent an investment panic, but at the same time they negatively affect investor's confidence)?
Short term and long term capital flows are two disparate phenomena with very little in common. The former is speculative and technical in nature and has very little to do with fundamental realities. The latter is investment oriented and committed to the increasing of the welfare and wealth of its new domicile. It is, therefore, wrong to talk about "global capital flows". There are investments (including even long term portfolio investments and venture capital) – and there is speculative, "hot" money. While "hot money" is very useful as a lubricant on the wheels of liquid capital markets in rich countries – it can be destructive in less liquid, immature economies or in economies in transition.
The two phenomena should be accorded a different treatment. While long term capital flows should be completely liberalized, encouraged and welcomed – the short term, "hot money" type should be controlled and even discouraged. The introduction of fiscally-oriented capital controls (as Chile has implemented) is one possibility. The less attractive Malaysian model springs to mind. It is less attractive because it penalizes both the short term and the long term financial players. But it is clear that an important and integral part of the new International Financial Architecture MUST be the control of speculative money in pursuit of ever higher yields. There is nothing inherently wrong with high yields – but the capital markets provide yields connected to economic depression and to price collapses through the mechanism of short selling and through the usage of certain derivatives. This aspect of things must be neutered or at least countered.
