Two decades of inflation and deflation

You can be excused for being confused about inflation, because inflation and deflation are all around us. The cost of labor is steadily rising but the cost of things (durable goods) has been falling for the past 20 years. On average, inflation has been relatively low, but behind the mask of modest inflation lies a reality that is confusing to say the least. Fortunately, it is very good news for the average worker.

You can best appreciate what's going on with prices by disaggregating the personal consumption deflator into two of its three components: services (a good proxy for labor costs) and durable goods:

For the past 20 years, and for the first time in modern history, the cost of services (labor) has been rising while the cost of "things" (durable goods) has been declining. From 1959 through 1994, durable goods prices never declined for more than a month or two. This changed starting in 1995, which was the year the Chinese yuan began to strengthen, the Chinese economy began to be liberalized, and China began turning into a manufacturing and exporting powerhouse. The net result of rising services costs and the relentless decline of the price of "things" is that the average person's standard of living has risen enormously in the past two decades. Service sector costs are up by about two-thirds, but durable goods costs have declined by almost one-third. That means that an average hour's worth of work today can buy almost two and a half more "things" than it could just 20 years ago.

Even though the prices of many essential goods have fallen enormously and our living standards have increased, in a technical sense—assuming it's actually possible to estimate just how much more value for our money we're getting when we buy durable goods these days—prices on average have been rising. The first chart above shows inflation according to the overall personal consumption deflator (whose components include services, nondurable, and durable goods) and the core personal consumption deflator (which excludes food and energy). The second chart breaks out the rate of inflation in services and durable goods. The past 20 years have seen service sector prices rise by 2.5% and durable goods fall by an annualized 2% per year. Nondurable goods (e.g., commodities) prices have risen by an annualized 2.0% over the same period. Overall, prices have risen an annualized 1.8% over the past 20 years.

To understand durable goods deflation, consider the iPhone, which was first released about 7 ½ years ago. Although the price of an iPhone hasn't changed much over the years, its capabilities have multiplied. Before the iPhone, portable phones were largely just that: portable phones. The first iPhone showed us that phones could also be computers and simple cameras. Today, the iPhone produces full-length, high-definition movies and breathtaking photos; it's a 64-bit supercomputer that fits in your pocket; it monitors your health; it pays your bills with the touch of your thumb; it gives you directions to any place in the world, and the best route to avoid traffic; it holds your entire music and photo collection; it is a trading platform for stocks and bonds; it's a real-time news ticker; it accesses the world's knowledge base in seconds; it takes dictation; it's a video arcade and a movie theater; it communicates with anyone in the world in seconds; it can hold a library of books; and it can diagnose illnesses, to name just a few of its hundreds of thousands of applications for this miraculous gadget. For a mere $650, the iPhone saves you tens or even hundreds of thousands of dollars. Meanwhile, smartphones have spawned new industries (app developers), disrupted others (taxis), and are revolutionizing many others.

One more example: As the chart above shows, the cost of personal computers and peripherals has fallen by more than 95% since the BLS first started tracking them in 1998. That's taking into account, of course, all the extra value (faster speeds, more capabilities, more memory) that, say, $1000 buys today vs. 15 years ago. And by the way, despite two decades of falling prices, the computer industry has thrived. Deflation is not necessarily a death knell for anyone.

The story of the iPhone and other marvels is the story of technological advances that have transformed our world, making it difficult if not impossible to measure "inflation" or living standards by any objective measure. Of equal importance, it's also a story that began with the opening of the Chinese economy in 1995, an event which resulted in unimaginable gains in the productivity of hundreds of millions of workers in the span of one generation.

It may be hard to understand, but it's good news for just about everyone.
