Economic Malaise And The Changing U.S. Economy

And now for your “put me to sleep reading”, here is a link to a paper on the changes in the American economy and their import. It is getting a lot of positive commentary from the economists’ blogs that I read, so I pass this link on if you have an interest.

Truth be told, I haven’t read it yet, but I will. But in addition to passing the link on to you, it also gives me a chance to excerpt this from Arnold Kling’s blog post on the paper.

1. In general, you have industries where productivity grows faster than demand, and you have industries where demand grows faster than productivity. Employment will shift out of the former and into the latter. An obvious point, but worth bearing in mind.

2. I think that if we want to know about the well-being of workers, we need to know something about their consumption patterns. If you mostly consume tradable goods (or lots of free stuff on the Internet), your income does not need to have increased in order for you to have experienced a big improvement in your well-being over the past two decades. On the other hand, if you want a lot of education and health care, then even if your income has grown a lot, you may be barely treading water.

3. Perhaps some people are using their incremental wealth to consume more leisure, while others are using their incremental wealth to expensive colleges and getting a lot of unnecessary diagnostic tests and elective surgeries. The latter will appear to have higher income and more consumption than the former, but who is really better off?

4. In general, the measurement of trends in economic well-being is going to be very tricky from now on. For an agricultural economy or an industrial economy, you can do a reasonable job by counting bushels or widgets produced. But the measurement of value added in education and health care is fraught with difficulty and major controversy. Moreover, if consumption patterns across individuals and groups are diverging as much as I think they are, then there really is no “average American household” to speak of, and the very process of aggregation is seriously misleading.

Those are pretty intriguing comments aren’t they. Now doesn’t that make you want to plow through the paper?
