Eastern Europe experienced another round of price hikes Friday as the former Soviet-dominated nations continued their painful adjustments to market-style economies.

Bulgaria took the biggest plunge as the government lifted price controls on foodstuffs, transportation and other basic services.The Balkan nation, already reeling from its worst economic crisis, joined Poland, Hungary and Czechoslovakia in attempting to bring supply and demand into balance.

The price of a kilo of pork shot up $1.50 to $7.86, while a liter of milk jumped sevenfold. The government also hiked the price of gasoline fivefold, even though there are virtually no supplies left in the country at legal outlets.
