The results show that most of the price variations are permanent with a major portion being deterministic__ The transitory variations in the consumer price index are only slightly greater than those in the wholesale price index_ Therefore, rem-seeking activities at the retail level are Although a similar pattern holds for the opt,' market versus official exchange rates, rent Neeking can be prevalent because the market is thin and operates on a spot basis. The study concludes that a forecasting strategy based on the Beveridge-Netson approach removes the bulk of uncertainty from prices, though risk cannot be avoided
