Talk:J curve

From Wikipedia, the free encyclopedia

wow. this is a seriously underdeveloped entry for the j-curve... i think i'll put some research together. —Preceding unsigned comment added by 24.128.27.160 (talk • contribs) 00:05, 15 December 2005 (UTC)

This cannot be right: "A lower exchange rate initially makes the trade balance... negative... as the goods and services being exported are being purchased for less domestic currency..." The exchange rate ensures that the same domestic money is earned despite the change in the foreign price (through direct change in exchange rate). For example, in simplest terms, at an exchange rate of $2 to the £, a £100 product would be on sale (ignoring transport, marketing costs abroad etc) for $200. Devaluing the £ so that the exchange rate is now $1.50 to a £ would mean the same good is now sold for $150 in the USA, but for each good THE BRITISH FIRM STILL EARNS £100 PER GOOD WHEN THE MONEY IS EXCHANGED. The firm's revenues only rise when more people start to buy that good. More demand obviously equals more money, but this is in the long run according to the j-curve, or at least made an ineffective change by demand for more expensive imports still being demanded for the short-run. This is not clear and, unless someone can show me otherwise, the statement above is an incorrect one.

You're ignoring the effect of imports on the trade balance. Yes, marginal revenues from exports remain the same during initial devaluation of the domestic currency; however, the marginal costs from imports increase and create a negative impact on the trade balance. Using your example, if we devalue the dollar to $2.5 against the pound, the same good now cost $250 instead of $200; thus, assuming the good is available domestically and of equal value, the demand for the foreign good would decrease in favor of the domestically produced good.

[edit] Neoconservative??

To Discotropico and 212.202.233.19...I object to the classification of the J Curve as "neoconservative". As it appeared to be original research, I've removed the references (on J Curve justification for war, neoconservative link, etc...) for NPOV reasons. Care to elaborate on your reasoning?

[edit] Need for improvement

Obviously a J curve is a mathematical entity first, and a statistical phenomenon second. How is a J curve described mathematically?

We need sources for all phenomena that are presently referred to as "J curves". It sounds almost like a prescription for crankery. JFW | T@lk 19:22, 28 May 2007 (UTC)

We how about we move the stuff about Medicine to another page. The Economics page should be separate from the MedicineMondaymonkey1 (talk) 21:58, 16 January 2008 (UTC)
