We study the generation of magnetic fields during inflation making use of a coupling of the inflaton and moduli fields to electromagnetism via the photon kinetic term, and assuming that the coupling is an increasing function of time. We demonstrate...

We discuss various realizations of the four dimensional braneworld inflation in warped geometries of string theory. In all models the inflaton field is represented by a Dp probe brane scalar specifying its position in the warped throat...

The purpose of this study is to examine the relationship between trade openness

size and inflation rate in Iran using ARDL method for the period 1973 to 2010. There is a

robust negative relationship across countries, first documented...

Many economic theories indicate that house price changes should have real effect on the

economy and vice versa. This study investigates the existence of causality among house

prices, economic growth, and inflation in Iran using...

The purpose of this research is to study the relationship between oil prices, economic activities and inflation of G7 countries over the period from 1975 to 2008 by applying panel data. Having analyzing the unit root test, it has been found that all...

The aim of this research is to study the relationship among oil prices,

market size and inflation in the North of Europe over the period 1980 - 2009

by applying panel data model. The unit root test shows that all variables are...

and to investigate the relationship between the fluctuations price of product agriculture with inflation and GDP is investigated. The range variance of total price of agriculture product of Iran had high fluctuations in period 1348 to1383 and maximum variance total...
