We construct an aggregate data panel for the GCC's six countries and verify the cointegration hypothesis among the variables of the money demand function using Pedroni's heterogeneous panel cointegration tests (2001). Then, we estimate the idiosyncratic, panel and group-mean cointegrating...

To study the elasticities of import demand function, we build a heterogeneous panel with data of 40 counties and use panel unit root tests (Im, Pesaran and Shin, 1997) and panel cointegration tests (Pedroni, forthcoming). We test our model with two previously used activity variables: GDP and GDP...

We construct an aggregate data panel to estimate price and income elasticities of the Arab countries imports from and exports to euro zone. We study the non-stationarity of our series and verify the cointegration hypothesis among the variables using Pedroni's heterogeneous panel cointegration...
