Karl “Chip” Case died on Friday, according to WSJ.
Case and Robert Shiller used real-estate transaction data from four cities to construct an index measuring price changes on the repeat sales of single-family homes, devising a more reliable way to measure changes in local home prices. In 1991, they formed a company with Allan Weiss, called Case Shiller Weiss, that produced the index.
In 2002 it was purchased by Fiserv and the index was expanded to measure 20 cities and became known as th Case-Schiller Index.
Now owned by Dow Jones it is a series of indices known as The S&P/Case-Shiller Home Price Indices.
