The asymptotic distribution of maximum likelihood estimators is derived for a class of exponential generalized autoregressive conditional heteroskedasticity (EGARCH) models. The result carries over to models for duration and realised volatility that use an exponential link function. A key feature of the model formulation is that the dynamics are driven by the score. Keywords: Duration models; g...

abstract: this paper discusses two topics. at first, it uses continuous wavelet (morlet) transform, coherency, and phase angle analysis to study the effect of mean volatility in opec crude oil prices, wti crude oil prices, brent crude oil prices and iran’s crude oil prices on the iran’s reer. to this end, the monthly data of the variables for years 2003 to 2012 is used. coherency analysis revea...

abstract in this paper, markov chain and dynamic programming were used to represent a suitable pattern for tax relief and tax evasion decrease based on tax earnings in iran from 2005 to 2009. results, by applying this model, showed that tax evasion were 6714 billion rials**. with 4% relief to tax payers and by calculating present value of the received tax, it was reduced to 3108 billion rials. ...
