Finance, Scrabble, and productivity

Free Exchange challenges a Dean Baker statement in which Baker essentially claims that the current economic situation is due more in part to the housing bubble rather than the financial sector.

Robert Waldeman hypothesizes that, in the 90s and naughts, the productivity increases were due to downsizing. It's an interesting idea--and quite possibly some of the story--but I think that, at best, it works in tandem with the standard theory. Who ever said that there could only be one reason for productivity increases in the 90s?
