For the past 25 years, inflation has averaged 1.8% per year, but that disguises the fact that prices of durable goods have been falling by a significant amount. Is that a problem? Hardly, since a big decline in the prices of durable goods has dramatically increased the purchasing power of the average worker.
Chart #1
Chart #1 it shows the three major components of the Personal Consumption Deflator index (a broader and better measure of inflation than the CPI): services (which are largely driven by wages and salaries), durable goods (e.g., equipment, computers, cars, TVs), and nondurable goods (e.g., food, gasoline, clothing). Total inflation over the time period represented here was 55% (an annualized rise of 1.8% per year), but looking deeper we see that wages rose 85% while durable goods prices fell 38%. At the risk of over-generalizing, this means that wages over the past quarter century have gone up 200% relative to the prices of durable goods (1.85/.62). That's equivalent to saying that one hour of the average person's work today buys three times more durable goods than it did 25 years ago. It's no wonder that these days nearly everyone has a smartphone and nearly every house has at least one big-screen flat TV.
Such a divergence between wages and prices has never happened before, as I first noted in a post over 9 years ago. Prior to 1995, there was never a time in modern history when any major category of prices experienced a sustained decline. Why did this change beginning in 1995? For one, that's about the time when personal computers began to proliferate. But it's also the case that 1995 marked the beginning of China's emergence as a major exporter of durable goods. China's economy has become a powerhouse of productivity as hundreds of millions of Chinese workers have benefited from the introduction of modern equipment and capital. This in turn has raised the productivity of all workers globally, and it has resulted in a significant increase in global economic prosperity. What's good for China has been good for nearly everyone in the world.
Chart #2
Computer deflation is coming to an end, however, as Chart #2 suggests. Note that this series began in 1998; prior to that the BLS didn't consider it important to create a separate price series for personal computers and peripherals. But by then they were already plunging in price. The cost of personal computers fell 36% in 1998, 22% in 2002, 12% in 2006, and 6% in 2010, but prices are down only 1.3% in the year ending last August. Computers and related equipment are not going to become ever-cheaper for much longer. Plus, the Chinese economy is slowing down and tariff wars are like sand in the wheels of commerce. It's been a great ride, but it's slowly coming to an end.
Chart #3
On the bright side, prices of nondurable goods haven't increased at all for the past 8 years (see Chart #1). And as Chart #3 shows, commodity prices in general haven't gone up for more than 10 years. Wages, in short, continue to go up relative to things. That's another way of saying that living standards continue to rise.
