Seasonality and jobs, one more time

Our thinking on the US recovery has been that things were never quite as bad as we feared in the worst of times (the last two Augusts), and never quite as good as we’d hoped in the best of times (the last two winters).

‘Tis the seasonality, hold the jolly

Endless worries about a eurozone disintegration and potential growth slowdowns across the developing world, but at least there’s been a streak of surprisingly not-terrible economic indicators in the US heading into the new year.

Or: feels a lot like December 2010, doesn’t it? Read more
