Krugman on Whether or Not There is a New Economy

Professor K is different from most commentators, and one way is that he's often willing to ruminate rather than pontificate. This is not a weakness if it's done well.

There is at least one important respect in which the 21st-century economy is different in a way that ought to have a significant effect on macroeconomics: the much larger role of rents on intangible assets. This isn’t an original insight, but I haven’t been finding systematic analyses of the point.

What do I mean by the role of rents? Consider the changing identity of the most valuable company in America. For a long time, it was GM, then Exxon, then IBM. These were companies with huge visible production activities: GM had more than 400,000 employees, which was amazing when you consider that the overall national work force was much smaller than the one we have today, Exxon had oil refineries. IBM was an information technology company, but it still had many of the attributes of an old-style manufacturing giant, with many factories and a large, well-paid work force.

But now it’s Apple, which has hardly any employees and does hardly any manufacturing. The company tries, through fairly desperate PR efforts, to claim that it is indirectly responsible for lots of US jobs, but never mind. The reality is that the company is basically built around technology, design, and a brand identity.
