Mack Loss Estimate Rises: Mack Trucks Inc. increased its projected loss for the year by 38%, saying questions about the U.S. economy and the Mideast crisis will cost the company $180 million in 1990. If the economic and political uncertainties continue into the next year, Mack also predicts a difficult 1991, when more stringent emission standards will increase truck prices. The Allentown, Pa., firm had originally predicted a loss of $130 million. In making the original estimates, the company said it counted on companies buying trucks in the coming months to avoid the price increases next year. But no surge occurred.
