The oil price and the real effective exchange rate (REER) are two important variables affecting OPEC countries politics and economy. Despite the fact that the existing theoretical literature confirms the relationship between oil price and the exchange rate (Dollar), there is no consensus about the direction of causality between these two variable. Also, statistical data shows that there is a sy...
Abstract This study goes beyond the the prevailing use of averaged data to investigate the hidden evidence of asymmetry due to the effect of monthly exchange rate fluctuations on Iran's quarterly GDP during the period 1380:1-1397-4. For this purpose, the regression model of Mixed Data with different asymmetric frequency (MIDAS model) is use, which allows time series variables with different fre...
It is well known that some XML elements correspond to objects (in the sense of object-orientation) and others do not. The question we consider in this paper is what benefits we can derive from paying attention to such object semantics, particularly for the problem of keyword queries. Keyword queries against XML data have been studied extensively in recent years, with several lowest-common-ances...
