Robert Shiller’s’ Paper on ‘The Volatility of Stock markets Prices’ published in 1987 uses dividend data and real interest rates to seek evidence that true investment value changes through time sufficiently to justify the price changes. His paper concluded that most of the volatility of the stock market prices appears unexplained. Shiller volatility or fluctuations prove that behavior of markets is not normal. Non normal distribution series is a widely followed proof of inefficiency in prices.

The authors of the current paper reanalyze Shiller’s data not for the change but for rate of change. The rate of change in dividend values, interest rates and market price is used to isolate temporal changes (time durations) defined in days. Though on one side the time duration data illustrate a non normal distribution and confirms Shiller’s non normalcy finding within value (fundamental data) and market data, it opens a larger debate suggesting temporal changes to be the reason for market volatility and inefficiency.
