Consider a hypothetical world economy with assets denominated in dollars and euros.
Why a lot of people think the CPI is not representative of their experience … and are right. At least partly.
Government statistics, particularly the CPI, have been in the news (e.g., [0]). Following up on my previous posts [1], [2], I want to take a stab at the question posed in the title.
This post focuses on issue separate from the mathematics of the index formulation, and has to do with what the typical weights at any given instant in time should pertain to. Should one use the expenditure weights that pertain to all the households aggregated in the economy? Or should one use the expenditure weights that pertain to the “typical” household? Kokoski (2003) [updated link] summarizes the distinction thus:
In the democratic index, the expenditure pattern of each household counts in equal measure in determining the population index; in essence, it is a case of “one household–one vote”. In the plutocratic case, the contribution of each household’s expenditure pattern is positively related to the total expenditure of that household relative to other households–in essence, “one dollar, one vote”.
Quarter 2 may come out OK, but challenges remain
At least that’s the assessment of Federal Reserve Bank of San Francisco economist John Fernald (hat tip: Mark Thoma).
IMF on the Global Macroeconomy, CBO on US-China Trade

IMF Gloomy on Growth, Sees Rising Inflation Threat

New estimates of the high school dropout rate
I was shocked by today’s report that the high school dropout rate in California has reached 24%.
The Expansion: Retrospect and Prospect, Whine-Free
The President’s press conference yesterday was meant to buttress consumer and investor confidence. I will leave it to others to evaluate whether he was successful in this endeavor [0]. I will also ignore his disingenuous remarks concerning how allowing drilling offshore and in ANWR [1] would somehow affect gasoline prices today in a noticeable manner, and focus instead on his repeated emphasis on the fact that the economy is still growing (although he never mentioned at what pace).
Did Fannie and Freddie cause the mortgage crisis?
Some thoughts about the role played by the GSEs in the run-up in mortgage debt and house prices.
Index Theory and the CPI
My previous post regarding government statistics elicited a lot of commentary, with a tremendous amount of vitriolic commentary directed at the current approach to calculating the CPI. Rather than provide more of my own thoughts on what constitutes an appropriate mix of theory and pragmatism, I will quote from the author whose work I had to read in graduate school, W. Erwin Diewert. From his entry in the 1998 Journal of Economic Perspectives which had a symposium on the Boskin commission report:
The Fannie and Freddie assistance plan
I see much to like about this.
Fannie Mae and Freddie Mac
How did we get into this mess, and how do we get out of it?
