Thanks to rampant inflation, this has been a summer of discontent for foodies, who have been forced to swap precious imported cheeses for Monterey Jack and to downscale barbecues from sirloin to skirt steak.

But as I discovered on a recent Maine vacation, there's at least one high-end food product whose price is falling this year: lobster. Based on my intensive investigations, it seems that prices for both the commodity (lobsters sold on the docks) and the finished product (steamed lobsters sold at dockside restaurants) are lower than they've been in past years. In a fish store in downtown Portland, a pound of lobster ($5.49) went for pretty close to what I had paid for a gallon of gas in Connecticut the day before ($4.30). A few years ago, the pound-of-lobster-to-gallon-of-gas ratio would have more like four to one. Our hosts welcomed us with two-pound lobsters that cost less than a pound of steak.

Deciding this economic anomaly needed more hands-on, butter-dipped research, I headed farther north, to Mount Desert Island. And as the population density and temperature fell, so too did the price of lobster. At Thurston's Lobster Pound restaurant – OK, a shack with tubs of lobsters, a big steamer, and a rickety wooden deck – shedders (soft-shell lobsters) went for a mere $7.00 per pound, while hard-shell lobsters were $9.00—a buck less than at restaurants nearer Portland. For the price of a quarter-pounder, large fries, and Coke at McDonald's, you could get a one pound lobster, accompanied by a quarter pound of butter.

What explains this crustacean mystery? Food inflation derives from several sources. The price of food can be driven upward by consumer and commercial demand, by speculation in the futures markets, and by producers successfully passing on the higher costs they incur (for gas, fertilizer, labor, processing, packaging, distribution) to buyers. The longer and more complex the supply chain (i.e. olives that are picked in Tunisia, then shipped to Italy to be turned into tapenade, then shipped to Dean & DeLuca's to be turned into hors d'ouevres for yuppies) the greater the opportunities for marking up prices and passing along costs.

At root, the global forces that are driving up the price of food don't significantly affect the vacation lobster business in Maine. Commercial and consumer demand doesn't vary much for off-the-boat lobster. Sure, many lobsters are sold to processing plants. But unlike other seafood products – think of canned tuna, or clam sauce, or frozen fish fillets – lobster is not produced or marketed on a mass global scale—which also means there are no speculators trying to make a killing on lobster futures. The fact that people are eating more and better in China and India isn't much boosting the demand for lobsters from Maine. Even in the U.S., lobster remains to a large degree a regional product. While you can find lobster on the menu at better restaurants in the Midwest, or, heaven help you, at The Red Lobster, you're unlikely to find live lobster tanks in Meijer stores in Michigan or Wal-Marts in the Ozarks. In addition, lobster is a luxury, discretionary food product that requires special equipment and extra fortitude to cook at home. (I watched in sympathy as one of our hosts, a Maine resident for two decades, winced in horror as she plunged the living creatures into a boiling cauldron).

With demand down, and with distributors facing higher costs, there has been significant pressure on lobster producers this food commodity to keep costs low. Wayne Seavey, a lobsterman who tends 600 pots in the frigid waters around Mount Desert Island, told me that he's getting about $3.50 a pound for lobsters this year, down from about $4 per pound last year. The reason, he says: distributors seeking to maintain their margins are cramming down the fishermen. And with limited local outlets (even swelled by summer visitors, the population of coastal Maine is relatively small), lobstermen can't hold out for higher prices.

Finally, lobsters remain cheap in Maine because of their simplicity. Raising them isn't a particularly energy-intensive business. Lobstermen have to gas up their boats, but they don't have to pay for fertilizer or feed. On the coast of Maine, lobsters are simply removed from their traps and put into tanks at dockside restaurants, or sold directly to home cooks, so there are precious few distribution, processing, or packaging costs to pass on. The only ancillary costs associated with getting lobsters from the dock to the table are (1) butter and (2) the statins that subsisting on a diet of rich lobster meat dipped in butter will require many consumers to take.
