… has been this one: Lessons from selling books on Amazon. I wrote this back in 2007. It’s gotten 15 comments (that’s a lot for UM, so no laughing), and I think the comments, not what I wrote, are what make the post so valuable. People sharing their experiences, and perhaps giving a bit of [...]

An odd, but perhaps perfectly understandable, compulsion
October 12th, 2010 · Comments Off · Economics, Rating & Review Systems
The FT reports that Google has now created a Google Price Index. Much like the Consumer Price Index (CPI), it is a measure of inflation. But while the CPI is constructed by real people (government and economist trained experts, we presume) entering real stores and recording real prices with pen and paper, the GPI is [...]

“Measuring the economic welfare … by the one-dimensional index ‘GDP’ is about as sensible as picking a mate from a group of candidates merely after seeing their feet”
May 26th, 2010 · 1 Comment · Economics, Rating & Review Systems
I came across this lecture — What Is The Wealth Of A Nation? (pdf) — by Uwe Reinhardt on the NYTimes Economix blog (where he posted of portion of the lecture). As the above quote from the lecture reveals, he is suspect that real wealth (as opposed to financial wealth) is easily captured in the [...]

Social currency is a nutty idea
September 12th, 2009 · Comments Off · Other Markets, Product Development, Rating & Review Systems
Social currency is a powerful thing. If you have it (say, as the president has it), then that is a very good thing. People respect you (as least we hope they do). A recent WSJ blog post, though, describes attempts by some people to make social currency into an actual, real currency. I have a [...]

A revised rating system from Prosper
September 2nd, 2009 · Comments Off · Financial Markets, Rating & Review Systems
For those of us who use Prosper (a peer-to-peer lender) as a place to invest, seeing as many charge offs (people who have defaulted on their loans) from highly rated borrowers as from poorly rated borrowers led us to believe that the rating system, well, kinda sucked. Prosper must have noticed the same thing and, [...]

Can a company be relied on for accurate rating of its products?
April 10th, 2009 · Comments Off · Rating & Review Systems
Case in point: Fresh Direct now has fruit ratings. Forgive me if I’m a little suspicious (and I hope it’s not indicative of my nature), but when a company starts rating it’s own products one has to cast a skeptical eye. In this instance, the fruit ratings are apparently given by Fresh Direct’s produce managers. [...]

“Whatever it is it’s rating system creep, and I don’t like it” #1
August 22nd, 2008 · 1 Comment · Fun, Rating & Review Systems
Starting with a quote from a co-worker and friend, welcome to the first installment of the “Whatever it is it’s rating systems creep, and I don’t like it” series (and perhaps contest). The first entrant is the Burj Al Arab Hotel in Dubai, which has discarded the 5 star system to award itself 7 stars. [...]

Rating Carbon Credit Projects
June 25th, 2008 · Comments Off · Energy Markets, Rating & Review Systems
The FT has this interesting piece in today’s paper regarding a new rating agency for carbon credits. The interesting bit: Carbon credits have come under increasing fire as investors, academics and non-governmental organisations have complained that many lack credibility. Recent studies have confirmed findings by the Financial Times last year that suggested as many as [...]
Doctors don’t need to fear rating systems … yet
June 19th, 2008 · Comments Off · Healthcare Markets, Rating & Review Systems
AMNews reports on a study by Harris Interactive (and commissioned by the California HealthCare Foundation), which describes how patients use physician rating sites. The hard numbers are: – 80% of Californians turn to the internet for health information (ok, no surprise here) – Less than 25% go to physician ratings sites (hm … ok) – [...]
