You wouldn’t think that people would complain about falling prices, but economists worry when it goes beyond a short run trend into the long term. An article in the Economist outlines the concern on a global level, and sites oil prices falling as a motivator in the current quarter’s fall of prices of 0.3%. Typically 2% increase is seen as a good equilibrium. Mentioning the drop of crude it notes that the decrease directly involves fuel and transportation costs of goods (while the service industry isn’t effected so much). And of course, while crude has dropped over 50% as a commodity, refined gas on average has only by a third or so due to a sort of ‘sticky prices’…easily will climb, yet not come down so easily!
