this paper employs a multivariate dynamic conditional correlation garch model, which is developed by engle (2001, 2002), to detect the timing and nature of changes in the comovement between iranian output and prices for the periods after iran–iraq war , known as imposed war . the results showed that there is a weak correlation between output and prices after imposed war and  varies periodically...

estimation of agricultural sector demand and supply and identification of its determinants could lead to more efficient policies and planning of this section. in this study, aggregate demand and supply of agriculture sector for years of 1959-2007 by using of nonlinear restricted armax model are estimated. result indicates that aggregate agriculture demand is inelastic in short and long run. tho...
