Using AFIRMA-M-HYGARCH model it is found that the structure of temporal profit was observed to change in three periods. Since the second and third periods are associated with lagged effect of heavy handed state intervention, it was possible to get an idea to the effect of such state policy. It...

The current study takes place in the Phillips curve framework in which first, we look at determining econometrics models leading to characterize the dynamics of the main variables underlying the trade-off in uni-variate contexts. As a result, it appears that an adequate way to characterize the...

This paper considers the application of long memory processes to describe inflation with seasonal behaviour. We use three different long memory models taking into account the seasonal pattern in the data. Namely, the ARFIMA model with deterministic seasonality, the ARFISMA model, and the...

This paper employs a combination of unit root tests and fractional integration technique to test for rational bubbles in Bombay Stock Exchange (BSE). It is indicated in the paper that evidence of a unit root in dividend yield is consistent with presence of rational bubbles in the stock prices....

This paper examines persistence in the Ukrainian stock market during the recent financial crisis. Using two different long memory approaches (R/S analysis and fractional integration) we show that this market is inefficient and the degree of persistence is not the same in different stages of the...
