There have been many studies that sought to examine this issue and their findings point out to hard work, previous schooling, parents ’ education, family income and self motivation as factors that have a significant effect on the students GPA. Most of those studies have focused on students ' performance in the U.S. and Europe. However, since cultural differences may play a role in shaping the factors that affect students' performance, it is very important to examine those relevant factors to the UAE society. The aim of this study is to investigate the socio-economic characteristics of students of the College of Business and Economics-UAEU in relation to these students ' performance and taking into account variables pertaining to the UAE Society. Using a sample of 864 CBE student and

Its goal is to verify the effect of natural resources exports on the economic performance. It considers the effect of cross sectional correlations and uses the corresponding panel unit root tests to study the long-run characteristics of our series. The results show that resources ' exports have no long-run relationship with the macro variables. A VAR analysis is used to estimate the short-run dynamics and shows that the effect of oil exports on those variables depends on local policies.

We test our model with two previously used activity variables: GDP and GDP minus Export for a performance comparison. To estimate our elasticities, we make use of two modified panel version of FMOLS and DOLS developed by Pedroni (1996, 2000, 2001). Our tests prove that GDP outperforms GDP minus Exports as an activity variable in the cointegration context. FMOLS and DOLS give close results when we do individual estimates. When we use between-dimension estimators, we get conflicting results. Then, we split our sample into developed and developing countries and show that income elasticity in developing countries are not different than unity on average and are higher than in developed countries contradicting previous literature results.

We study the non-stationarity of our series and verify the cointegration hypothesis among the variables using Pedroni's heterogeneous panel cointegration tests (2004). The panel data circumvent the problem of short span sample and increase the power of the non stationarity tests. Then, we estimate the idiosyncratic and panel cointegrating vectors using DOLS (Kao and Chiang, 2000), FMOLS (Phillips and Hansen, 1990) and group-mean DOLS and FMOLS developed by Pedroni (2000, 2001). Our variables are shown to be cointegrated. Arab imports from Euro zone countries are income inelastic, but price elastic. Results of export function are not conclusive and depend on the estimator

Then, we estimate the idiosyncratic, panel and group mean cointegrating vectors using FMOLS and a modified version of FMOLS developed by Pedroni (2000). We find strong evidence of cointegration amongst our variables. The estimated elasticities have the expected signs in general but are significant only in the case of the scale variable. The group mean estimator produce sensible results and shows results conformed to the theory. Real M1 shows a better performance than real M2.

We calibrate and simulate the model in order to assess the role of wage contracts in explaining the features of recent real-world stabilization programs. We show that a policy package with a significant reduction of public sector deficits can reproduce qualitatively most of the observed comovements among macroeconomic aggregates. However, the responses of the model's endogenous variables to the implementation of the stabilization program are not as pronounced as in the data.
