* European shares up 1.8 percent, Wall Street set for positive start
* Oil rises above $50 on Gaza, Russia-Ukraine worries
* Dollar climbs against major currencies

LONDON, Jan 6 (Reuters) - Investors bet on a global economic recovery on Tuesday, lifting European and Asian shares for the sixth and seventh consecutive sessions respectively, while political events drove oil above $50 a barrel.
Wall Street looked set for a positive start and the dollar climbed strongly against major currencies, particularly the euro.
Expectations that U.S. President-elect Barack Obama will offer $310 billion in tax cuts as part of a $775 billion plan to support the economy have fed into a tentative recovery in global equity markets.
German politicians also debated tax cuts to revive Europe's largest economy. [
]The pan-European FTSEurofirst 300 <
> index of top European shares was up 1.8 percent. It has now gained around 18 percent since hitting a low in late November."The main things are the Obama plans as well as the German fiscal stimulus package," said Bernard McAlinden, market strategist at NCB Stockbrokers. "Markets, rather than focusing on the dire economic and earnings data, are looking forward to the hope that these plans will work."
In Japan, the Nikkei 225 <
> closed up 0.4 percent and the MSCI index of Asia-Pacific stocks <.MIASJ0000PUS> outside Japan edged up for a seventh straight day, gaining 0.48 percent.Higher oil prices helped boost energy stocks, but sharp gains may cause some headline inflation problems later for central banks intent on cutting interest rates.
Crude hit a one-month high above $50 a barrel, driven higher by heightened concern about supply disruptions stemming from Israel's incursion into Gaza and a dispute between Russia and Ukraine over natural gas.
"Oil prices continue to be supported by political issues, whether they be gas or Gaza related," Rob Laughlin, broker at MF Global, said.
U.S. crude prices <CLc1> rose $1.25 to $50.06 a barrel after gaining 5 percent overnight.
DOLLAR SURGES
The dollar jumped nearly 1.5 percent against a basket of currencies <.DXY>, particularly gaining against the euro, which fell sharply on speculation the European Central Bank will cut interest rates further as price pressures ease and euro zone economies weaken.
"With the situation in Europe deteriorating quite rapidly it leaves the euro quite vulnerable," said Ian Stannard, senior currency strategist at BNP Paribas in London.
The euro <EUR=> fell around 1.9 percent to $1.3351 according to Reuters data. Against the yen, the dollar rose 0.7 percent to 94.08 yen <JPY=>.
On euro zone government bond markets, the interest rate-sensitive 2-year Schatz yield <EU2YT=RR> was flat at 1.694 percent, while 10-year Bund yields <EU10YT=RR> were up 4 basis points at 3.058 percent. (Additional reporting by Joanne Frearson and Veronica Brown, editing by Patrick Graham)
