International residential prices

FRED recently added a long list of international residential prices from the Bank for International Settlements. The graph above, which offers only a small glimpse of what FRED has to offer, compares the evolution of residential prices for a few countries. Note that the indices are all normalized in 2010, which highlights the large run-up and drop prior to that year in the United States. Similar events also occurred in the other countries, though the effects were much more muted. Surprisingly, Canada seems particularly immune from developments in the United States, except for a temporary drop in 2008.

How this graph was created: Go to the BIS release and select the relevant series. Click on “Add to graph.”

More prices that deviate from the CPI

We recently discussed some CPI categories that do not tend to have rising prices. Those examples were all linked to information technology. Here’s a wide variety of categories where prices can decrease or remain stable for long periods. For example, coffee is subject to wide fluctuations, including steep price drops. Apparel became disconnected from the CPI sometime in the early 1990s and remains largely constant. It is more surprising that cosmetics and musical instruments are also consistently below general inflation or even flat. In the motor vehicles category, some quality improvements only partially affect the overall price of motor vehicles; this is another example, much like computers, of a category that does not closely follow the overall path of the CPI.

How this graph was created: Start with the graph for the CPI, then add the other series. Change the color of the CPI line to black and thicken it to distinguish it from the many other series.

Not all prices increase

It is natural to complain that some prices increase. But don’t forget that prices can also decrease. While there are obvious seasonal fluctuations for some goods (say, agricultural products), other goods have been declining year over year, contributing to a general price inflation that is lower than one may think. The prime example shown here is anything related to information technology. It is no secret that IT devices with a given set of characteristics have continuously fallen in price. Or, to put it differently, a device of the same price year after year will provide much better performance; its price by “unit of performance” must therefore be declining. This graph shows some CPI categories where advances in IT have lead to price decreases. Or at least no price increases. This is not restricted to the IT category, of course. A future blog post will explore more examples on this topic.

How this graph was created: Search for CPI, then add the other series. Because their base years are different, the axis labels get crowded. So, these were removed by unchecking “Axis titles” in the graph settings.
