Why macroeconomics is not a science

From the United Kingdom:

Manufacturers enjoyed a jump in demand that pushed growth to its fastest rate for more than two years and saw the sector take on thousands of new staff last month.

New orders were the strongest for almost 20 years and job creation accelerated, according to the Markit/CIPS UK Manufacturing PMI survey.

There is more here, and I will reiterate that this trend was not very well predicted by any macroeconomic school of thought, including liquidity trap theories, recent emphases on long-run secular stagnation, or for that matter the contrasting “of course there is mean reversion” approaches, which don’t tell us much about timing and which would appear to contradict the slow recoveries seen elsewhere.  Spain, by the way, does not have an equivalent degree of cheer
