The following schedules summarize the supply and demand for trifflings, the national currency of Tricoli: US dollars per triffling $0 $2 $3 $4 Quantity demanded 12 10 8 6 Quantity supplied 1 4 8 12 546 $6 $7 20 22 1 24 a. Graph the supply and demand curves on the next page. b. Determine the equilibrium exchange rate. c. If Tricoli was running a persistent and significant increase in imports (but no change in exports) over a long period of time, how would this be likely to impact the supply curve for trifling (assume no significant "Capital Account" flows other than those needed to finance the trade deficits)? d. What is likely to happen to the (international currency) dollar value of triffling as a result of these persistent trade deficits? How this effect Tiffoli's Current Account balance? e. Is this a realistic proof that under a "free trade" regime, global trade will tend to self-adjust toward Current Account balanced trade? Why or why not?
