this article analyses the effects of foreign exchange commitment and exchange rate unification policies on iran’s non-oil exports during the last three decades. in addition, the effects of these policies on non-oil exports have empirically been estimated. for this purpose, an export supply model was estimated using the econometrics technique of auto regressive distributed lag (ardl) and reliabl...

water saturation and cation exchange capacity are the most significant parameters used to calculate a hydrocarbon zone potential. in clean formations, by applying the famous archie model, which assumes that in the formation the only electric conductor is the formation water, the water saturation can be calculated. additionally, in shaly sand formations this assumption may not be true as the ion...

this paper empirically investigates the exchange rate effects of iranian rial against dollar (rial vs.us) on stock prices in iran. the sample period for the study has been taken from march 20, 2004 to march 20, 2010 using daily nominal exchange rate of rial /us and daily closing values of tehran stock exchange. generalized autoregressive conditional heteroskedasticity (garch) model has been use...

explanation relation between risk and return and capital asset pricing are concepts which is appointed as dominator and major paradigms in capital markets. so far as after offering capm by sharp & lintner, this model has been revised and criticized frequently. in this paper another version of capm has been tested versus traditional capm in tehran stock exchange. this version of capm measures se...

In this study, 3 models of Time-Varying Parameters (TVP), Dynamic Model Selection (DMS) and Dynamic Model Averaging (DMA) and a comparison with the Ordinary Least Squares (OLS) method in MATLAB in the time period 2003-2013 (with data on a monthly basis) are discussed. In the present study, the variables of unofficial exchange rate changes, interest rate changes and inflation in oil price foreca...
