Talk:Impossible trinity

Capital controls
Is there any evidence, or citation for the assertion that capital controls are "easily evaded?" DOR (HK) (talk) 09:19, 11 February 2009 (UTC)


 * Easy to find citations on this, although not accepted as a universal truth. See article summary here or another here ("Empirical evidence, however, generally challenges belief in the effectiveness of capital controls"), here, and here. Google can find many more, google scholar no doubt too. But the "empirical evidence generally challenges belief in effectiveness" summarizes pretty well (and then economists try to figure out in exactly which circumstances).--Gregalton (talk) 07:58, 12 February 2009 (UTC)

What about China & India?
The statement "Hence, there is virtually no important country which has an effective system of capital control" seems to contradict the information given on Renminbi page that China (and India?) has maintained capital controls, particularly in light of the 1998 Asian Crisis. Helvetius (talk) 12:58, 16 October 2009 (UTC)

This quote (no important country which has effective capital control) is ridiculous. Unless we are holding "capital control" to some impossible platonic standard, we see clear examples of at least relatively successful (very successful, I would argue) capital controls in India and China. Consider the domestic debt markets of these nations - domestic bonds are so incredibly difficult for foreigners to buy that the JPMorgan GBI-EM Index Global REMOVES India and China from the index entirely as they are impossible to access for international investors. I'm pretty sure the fact that even JP Morgan considers this market completely off-limits to even the most powerful, wealthy investors shows quite well that capital is, in fact, controlled quite strongly for two undeniably "important" countries.

Title
Should this article be under "Impossible trinity" or under "Trilemma (economics)"? Volunteer Marek 19:09, 26 February 2012 (UTC)


 * I came here to write this exactly. I couldn't find any prominent source that calls this "the Impossible trinity", 79.45.21.49 (talk) 13:16, 4 June 2024 (UTC)

Error in illustration
The new SVG version of the figure is pretty, but misspells "Monetary". I'd fix it if I had the tools. Anyone else? 170.140.151.59 (talk) 16:10, 27 April 2012 (UTC)

Dr. Benassy-Quere has reviewed this Wikipedia page, and provided us with the following comments to improve its quality:

"- The impossible trinity is not a "hypothesis", but a theoretical result from the Mundell-Fleming model. - "Most other countries have opted for the second one (b)" is not true. Most countries refrain from letting their exchange rate float freely ("fear of floating", cf. Calvo and Reinhart). - Theoretical derivation: the example given relies on static (or naive) exchange-rate expectations. - Dilemma: the quote from Krugman refers to "corner solutions" (either free float or fully fixed exchange rate) rather than to "the possibility of a dilemma". The latter has been introduced by Helene Rey showing that, whatever the exchange-rate regime, monetary policy is strongly inflienced by the fed's policy. - Impossible trinity and historical events: I would use the European crisis of 1992-93 rather than the Asian crisis which in my view is a third generation currency crisis.
