I doubt it, his predictions on almost anything have been woefully wrong over the past 3 years. Remember that phrase 'the green shoots of recovery'? That came from King at the BoE in 2011. Since then, things have got a whole lot worse.
Osborne will eventually do a U-Turn and abandon or slacken the austerity measures that have crippled growth. Though it is getting rather late in the day to have any major effect on the economy before the Conservatives face the electorate and what looks at the moment like a resounding thrashing.
Osborne will resort to plan B and some money will trickle into intrastructure and building projects but as his heart isn't really in it, it will be half-arsed and not be very successful.
Far from Labour squandering the proceeds of a recovery, there won't be one. The Conservatives do not have the political will to it. They have been joyfully printing money so they can claim to be paying off the bankers mess.
The sooner they are out the better.
