Japan and the USA seem to be embroiled in a Currency War. This sort of thing is brand new to me, and I'd like to understand it better. Here's a link to what I refer: http://story.news.yahoo.com/news?tm...749&e=1&u=/nm/20031002/bs_nm/markets_forex_dc The really simple concepts are clear, if Yen(s?) cost more dollars, then Japanese exports to the USA rise in price, and USA imports drop, and that theoretically hurts Japan's economy but helps the USA's. I'm not so sure, but that's not even my main confusion. My main question is, isn't this sort of thing really expensive, and thus a drag on the economy in question? And, if a Currency Squabble becomes a Major Engagement, isn't that gonna be even worse? And if it does, isn't Japan gonna be on the Big Bonehead side that loses? Any thoughts would be appreciated.
