      Nekhili, R.; Altay-Salih, A.; Gençay, R. (Elsevier, 2002)
      The performance of the well-known stochastic processes used for the empirical distribution of the exchange rate returns at different time scales was discussed. The parameters of the candidate processes at different time ...
    • Financial earthquakes, aftershocks and scaling in emerging stock markets 

      Selçuk, F. (Elsevier BV, 2004)
      This paper provides evidence for scaling laws in emerging stock markets. Estimated parameters using different definitions of volatility show that the empirical scaling law in every stock market is a power law. This power ...
