NEW YORK, April 14 (Reuters) - Stocks on major world markets and the U.S. dollar slipped on Thursday as Greece's debt problem, Chinese inflation and disappointing U.S. jobs data stoked worries over a global economic slowdown.

Bonds and gold rose as uneasy investors sought safe-haven from stocks and riskier investments.

"We do have to scale back growth expectations. The market is more concerned about what growth will be like with rising input costs," said Jerry Webman, senior investment officer and chief economist at OppenheimerFunds in New York.

U.S. oil prices climbed on the weaker dollar.

World stocks, as measured by the MSCI world index <.MIWD00000PUS>, dipped 0.1 percent despite a burst of corporate activity that would usually lift investors' spirits. On a year-to-date basis, the index was still up 4.1 percent.

European stocks <.FTEU3> ended down 0.6 percent.

Wall Street stocks ended little changed, erasing earlier losses on late buying in energy and consumer staples.

Analysts said the choppy session underscored the current divide among investors, which could keep stock markets in tight trading ranges in the coming weeks.

"The 'risk-on' and 'risk-off' trades are battling right now," said Perry Piazza, director of investment strategies at Contango Capital Advisors in San Francisco .

The S&P 500 index closed up 0.1 percent at 1,314.52, while the Dow finished up 0.1 percent at 12,285.15. The Nasdaq closed flat at 2,760.22. For more, see [.N]

In Tokyo, the Nikkei <.N225> closed up 0.1 percent after Wednesday's late U.S. gains.

The initial weakness in U.S. and European stocks came after a report that said Chinese inflation would reaccelerate after slowing recently. Hong Kong's Phoenix TV, citing an unnamed source, said China's annual inflation rate in March was likely to be 5.3 percent to 5.4 percent, a 32-month high and just above an estimate in a Reuters poll.

Investors are concerned about Chinese inflation in case the government attempts to restrain it by raising interest rates, prompting a 'hard landing' for the economy.

Huge figures on China's foreign exchange reserves and money supply growth also fanned worries over how aggressively Beijing will confront inflation. [ID:nLDE73D17Q]

While investors fret over a global slowdown and rising inflation, economists in the latest Reuters poll predicted world growth of 4.2 percent this year and 4.3 percent in 2012, unchanged since the January poll. See [ID:nLDE73D0XY]

Investors, despite their reservations about the global economy, snapped up shares of Zipcar Inc. in its debut on Nasdaq. Shares of the U.S. car-sharing company rose more 50 percent to $27.83. For more, see [ID:nN14149168]

PERIPHERAL WORRIES

Stock losses grew as Greek bond yields soared, with markets pricing in a greater probability that Athens would be forced to restructure its runaway debt. Yields of other peripheral euro zone states also rose sharply. [ID:nLDE73D153]

Some analysts say stronger members of the euro zone could fight off the drag from weaker ones.

"Europe is probably on the mend without saying the pain in the peripherals is over," said Sam Wardwell, investment strategist at Pioneer Investments in Boston.

A year ago, the deterioration of Europe's sovereign debt problem held back the global recovery and forced the European Central Bank to leave rates steady longer than expected.

Adding to jitters over the bailout cost in Europe was the toll on Japan from last month's deadly quake and tsunamis.

The Reuters Tankan survey of 400 large firms found on Thursday that power shortages caused by the crippled Fukushima nuclear plant had hit nearly 60 percent of local companies, disrupting production and supply chains. [ID:nnLME7DP00Q]

In the United States, a surprise rise in jobless claims raised doubts over the recovery in the labor market. [ID:nN14146589]

Renewed anxiety over the U.S. economy hurt the dollar, and traders bet the Federal Reserve will stick to its ultra-easy policy even as the ECB and other major central banks raise rates to curb rising price pressures.

The weaker dollar supported oil, despite worries over less demand if the world economy slows.

U.S. oil prices jumped $1.26, above $108 a barrel. But in London, May Brent crude expired down 52 cents at $122.39. For more, see [O/R]

Gold prices gained 1.2 percent on the day to $1,472.67 an ounce.

U.S. Treasury prices fell in a choppy session, despite strong demand at a $13 billion auction of 30-year bonds. The benchmark 10-year yield last traded at 3.50 percent after touching its lowest level in about 1-1/2 weeks. [US/]
