US president-elect Barack Obama has expanded the goals of his proposed economic stimulus, with a plan to create or save an additional 500,000 jobs. Obama raised his jobs target over the next two years to 3m, up from 2.5m set last month, after US unemployment hit reached a 15-year high in November. Obama agreed the outlines of a $675bn to $775bn two-year recovery plan last week but officials say the price tag is likely to rise above $800bn as Congress makes its own demands during the legislative process.
