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 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

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.

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 socioeconomic 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 regression analysis, our results show that the most important factor that affects student's performance is the student's competence in English. Besides competence in English, students who participate in class discussion and those on leave outperform other students. The factors that negatively affect student's performance the most are missing too many lectures and living in crowded household. The results also show that non-national students outperform national students and female students outperform their male counterpart.

The study uses a randomly collected sample from the Lebanese working population in the greater Beirut area applying the counterfactual decomposition and the generalized quantile regressions. Most of the results support previous research which concludes that the human and social capital indicators have a significant impact on earnings and that the wage gap is mainly due to structural effect. Moreover, the results show evidence of quicksand and glass ceiling effects that limit female income.

We examine various characteristics of the higher education sector and discuss their inherent strengths and weaknesses in light of Dubai’s labor market needs. Our findings reveal that the UAE higher education sector has witnessed an impressive growth since 1997 mostly led by a vigorous expansion of the private higher education sector. This situation led to a substantial growth in higher education opportunities for the UAE population. However, the lack of development of graduate studies and the lower quality of graduates, as perceived by both employees and employers, represent the main challenges to the capacity of the sector in fulfilling the needs of Dubai’s economy.

The five countries are Bangladesh, India, Nepal, Pakistan and Sri Lanka. The goal is to study the money demand function of those countries. Our results show that money demand (M1) is cointegrated with all determinants, which indicate that (M1) money demand function is stable, whereas the money demand (M2) is not. Two estimators are used in this study: FMOLS and DOLS. Most of the individual income elasticities are positive and significant as expected using both FMOLS and DOLS. Whereas the individual elasticities in respect to interest rate and exchange rate are not all significant. However, the group panel estimates for all the three variables are significant and have the expected sign using both FMOLS and DOLS.

The paper further examines the wage distribution and the decomposition of the wage gap between the public and the private sectors. Results of the study are consistent with the dual labour market theory and indicate that the labour market in the United Arab Emirates is segmented based on sectors (public versus private) and types of workers (nationals versus non-nationals). The study concludes with a discussion of the implication of these findings for the effectiveness of labour and economic policy.

The results indicate that, in the long run financial development and economic growth may be related to some level. In the short run, the panel causality tests point to real economic growth as the force that drives changes in financial development while individual countries' causality tests fail to give a clear evidence of the direction of causations.
