“there’s a simple enough explanation for at least part of it: simply globalisation.
Now what is it that we know about American companies and their profits? Something that has rather changed over the past decade or so? Yes, that’s right, we’re in a huge period of globalisation. So much so that US companies are now making very large profits outside the US economy. Apple AAPL -1.58% is making phones (or having made for it) in China and selling them in Europe. This isn’t, in any real sense, part of the US economy. The same goes for Google GOOG -1.53%, Microsoft MSFT -11.37% and however many other companies you want to study. Profits are being made offshore, out there in the global economy.”
But this is just wrong. According to the Bureau of Economic Analysis (see Table 12 of the BEA Q1 2013 release), aggregate corporate “rest of the world” profits – i.e., large US corporations with earnings abroad – declined $8.9 billion in 2012.
The surge in 2012 corporate profits occurred on account of domestic corporate profits rising 10% to $1.5 trillion in 2012.
True, corporations have gone global but that does not explain the surge in corporate profits since the end of the financial crisis. The surge has been home grown.
