Would innovation stop inflation?
The FT has a new article by Rana Forooher entitled “How innovation could stop inflation“. The article focuses on how innovation is transforming all sort of industries, from energy to transport to computers. Lots of exciting things are happening.
After reading the article, I wondered why the FT had not entitled it “Why innovation could boost real GDP”. After all, you could remove all mention of “inflation” from the article, and still make the same basic points. So why are these issued framed in terms of inflation, and not in terms of RGDP growth?
If we were on the gold standard, the title would make perfect sense. Under a gold standard, global NGDP tends to rise at roughly the same rate as the gold stock. Anything that boosts global RGDP without boosting global gold stocks (a big assumption, BTW), tends to push the price level in the opposite direction. This explains why there was almost no long run inflation under the international gold standard.
For the same reason, if we currently had NGDP targeting then the title would also make perfect sense.
But we don’t have a gold standard and we don’t have NGDP targeting. We have inflation target, at 2%. So why would anyone expect long run technological change to have any impact on inflation? Why wouldn’t faster RGDP growth merely lead to faster NGDP growth, leaving the inflation rate stuck at 2% on average, over the long run?
Just to be clear, in this post I’m not being sarcastic, and I’m not taking some sort of weird market monetarist perspective. Unless I’m mistaken, a New Keynesian or an Austrian would be equally perplexed by this FT article. I’m sincerely asking the following question:
When reporters talk about inflation in this way (and it occurs quite often), exactly what are they assuming about the monetary regime?
Are they claiming that although the major central banks claim to target P, they actually target NGDP? If so, I hope they are correct. But does that assumption actually seem plausible?
