This is all the more true because, as the research has shown, a larger portion of cross-border investment in the modern era appears to be in sectors in which financial performance and the valuation of assets are harder to gauge. In those circumstances any hint of governmental support is certainly to be avoided.
Recently some have proposed the creation of “target zones” for major currencies, presumably in order to create, in part, greater stability in global financial markets. I think that these proposals are unlikely to work.
