Abstract

The Conditionally Exponential Decay (CED) model is used to explain the scaling laws observed in financial data. This approach enables us to identify the distributions of currency exchange rate or economic indices returns (changes) corresponding to the empirical scaling laws. This is illustrated for daily returns of the Dow Jones Industrial Average (DJIA) and the Standard & Poor’s 500 (S&P500) indices as well as for high frequency returns of the USD/DEM exchange rate.
