I have had a number of eBay merchants write me about a post that I made earlier this week suggesting that eBay seems to be displaying the early signs of a Market for Lemons problem (Some would argue it is far beyond the beginning stages, but I will let you debate that with your comments below).

Without focusing on eBay or eCommerce in general, it has been requested that I illustrate a simple example of how a “Market for Lemons” develops.  Obviously, there is a lot of academic research on this subject (I posted a Wharton case study by Dr. Eric Clemons earlier this week, and you won’t want to miss it since it discusses eBay’s challenges in greater depth.), and almost everybody has heard the “Market for Lemons” term utilzed at some point.  Wikipedia provides a basic overview of the Market for Lemons economic concept, so I won’t regurgitate what you can read elsewhere.

In short, the “The Market for Lemons: Quality Uncertainty and the Market Mechanism” is a paper written by George Akerlof in 1970 that describes what happens to markets that suffer from information asymmetry problems.  Ultimately, Dr. Akerlof won the Nobel Prize for Economics in 2001 (along with Michael Spence and Joseph Stiglitz) for his analysis of markets with information asymmetry.  While I was at Wharton, I was fascinated by the implications of this research on eCommerce marketplaces.
