Tecnologia, bem-estar e crescimento do PIB

The Great Ephemeralization, por Timothy Lee:

Suppose we lived in the world of Harry Potter, and one day in the late 1950s RCA hired a wizard to wave his magic wand and transform all of the world’s black and white sets into color sets. This would clearly represent a large increase in the standard of living—a larger increase, in fact, than the non-magical process whereby people have to buy new, more expensive, televisions. Yet the government in the alternate universe would almost certainly have recorded a smaller increase in GDP. Our own BLS would see consumers buying more expensive televisions while in the Harry Potter universe consumers would be happy with the old, cheap ones. Hence, consumers circa 1970 would be wealthier in that universe than in ours, but official GDP statistics would show just the opposite.  (...)

[Tyler] Cowen writes that the Internet is producing wealth that “is in our minds and in our laptops and not so much in the revenue-generating sector of the economy.” This isn’t exactly wrong, but it fails to appreciate the extent to which the software industry is entangled with the “revenue-generating sector of the economy.” The digital revolution isn’t just introducing novel ways to amuse ourselves, it’s rapidly displacing a wide variety of “revenue-generating” products and services: typewriters, newspapers, magazines, books, maps, cameras, film development, camcorders, yellow pages, music players, VCRs and DVD players, encyclopedias, landline telephones, television and radio broadcasts, calendars, address books, clocks and watches, calculators, travel agents, travelers checks, and so forth. (...)

Every time the software industry displaces a special purpose device, our standard of living improves but measured GDP falls.
