Japan's Dual Currency Proposal: A Slippery Slope

Terrible proposal, you only need to look at the most recent 'stimulus spending' to see how disastrously allocated it had been. Why does none of these Keynesians EVER look at the debt side?

You can cheat your maths teachers but not maths principles.

Why Hasn't the Bank of Japan Intervened to Weaken the Yen?

Wild shot here: can Japan actually depreciate its currency? By that I mean are they politcally capable of doing so? As a country that is heavily-reliant on US support to defend itself and hugely involved in American business the cynic in me thinks that America's leverage because of that protector-role over Japan is such that Japan is quite simply not in the position to depreciate its currency as a higher yen gives the US some breathing space.

European Policymakers Fire First Shots in Currency War

Whilst it may seem good the the pound is falling the question is how this really benefits the UK economy as huge importer, how many competetive export-orientated industries does it still have (a weak currency now is of little help if the industry is no longer exists in the country..) and how will the fall in supply of North Sea oil affect its import bill if the pound continues to be weak?
Britain actually needs a strong pound.
Not so sure on the yuan, I can even see it appreciate against USD/Euro.
