The main scope of this paper is to investigate the possible existence of a metallicity dependence of the overshooting from main sequence stars turbulent cores. We focus on objects with masses in the range ∼ 2.5M ⊙ − ∼ 25M ⊙. Basically, evolutionary time scale ratios are compared with star numbers ratios on the main sequence. Star populations are synthesized using grids of evolutionary tracks co...

Newer applied macroeconometric models have adopted a mixture of paradigms to capture at least the major differences between the behavior of financial markets and markets for commodities and for factors. Thus, in the Murphy Model of the Australian macroeconomy (MM), rational expectations and very rapid adjustment are assumed to apply in markets for financial assets, but frictions and departures ...

The exchange rate plays an essential role for firms which export goods and import raw materials. In this paper, the effects of real specific exchange rate fluctuations in imports, exports and aggregate trade on industry sector, chemical and transportation industries outputs in 49 OIC countries were investigated by using a panel data model over 1990-2014. Particularly, this paper presents eviden...

I n this paper, the evaluation of the real exchange rate transfer and the asymmetric transmission of real exchange rate fluctuations to the export prices of food products for the country during the period (2001-2015) was studied using two approaches of PMG and GMM systems. The TGARCH method was used to calculate the real exchange rate fluctuation index and the Markov Switching method was u...

exchange rate has the fundamental role as one of the economy key variables in determining the domestic price. so it is important to know how is the empirical relationship between the exchange rate and domestic prices and the factors influencing this relationship. the main objective of this study is to determine the effect of vehichel imports share on the exchange rate pass – through on domestic...

This paper investigates the effect of exchange rate uncertainty on the Iran’s import trade. The exchange rate ‎uncertainty series were generated utilizing the TARCH model. This model analyzes the asymmetric effects. The analysis of uncertainty and asymmetry ‎of the exchange rate shows significant TARCH ‎effect on Iran’s exchange rates‎. The findings of the study indicate negative shocks (bad ne...

One of the main issues in international finance is the ratio of exchange rate pass through to consumer prices. The main objective of this study is to examine the exchange rate fluctuations and its asymmetric effect on consumer prices in Iran’s economy. In the present study, the effects of positive and negative impacts of the exchange rate on inflation rate and other macroeconomic variables of I...
