In the face of economical troubles, Americans are pondering what is better: a weak dollar or a strong dollar. A weak dollar will make American goods more competitive, which will push the economy towards expansion. On the other hand, a weak dollar will make foreign investments in the American economy less attractive, which will hamper the expansion.
Thus, weakening dollar conflicts with the amount of foreign investments, and strong dollar conflicts with the competitiveness of American goods. Both factors, foreign investments and competitiveness of the goods affect the size of the American economy.
The experts push the American administration in the direction of finding a balance between the two. What else would you expect ? They are not familiar with TRIZ !
The TRIZ approach is to resolve the contradiction. There is a small obstacle on this way, however. A contradiction matrix for economical contradictions does not exist. But let us try Altshuller's contradiction matrix first. May be it will suggest us something !
Since the size of the economy is measured in dollars, strengthening the dollar amounts to increase in the size of the economy (parameter #8) as measured by other currencies. On the other hand, decrease in foreign investments is analogous to "acting harmful factor" (parameter #30) The matrix suggests principles 19 ("periodic action"), 27 ("inexpensive, short-lived object for expensive, durable one"), 34 ("rejecting and regenerating parts"), 39 ("inert environment").
Of all of them, just "periodic action" seems to be suitable. It might mean periodic weakening and strenthening the dollar. It should be weak during sales peaks (or during the peaks of manufacturing activity - depending on circumstances), and strong all other times.
Did anybody try it ?
