The results in four frame with panel data method indicated that in high-income countries, economic and social aspect of globalization had significant positive effect on economic welfare while political globalization had no statistically significant effect. While, in the middle-income countries only economic aspect of globalization has significant positive effect on economic welfare. In low-income countries also, economic welfare is affect inversely from economic and political globalization and political globalization has not significant effect on welfare. In general, one can say that non-political aspects of globalization were been affected on economic welfare in the selected countries.

Abstract The purpose of this paper is to investigate the distributive and welfare effects of the transition from the current payment system to a partially funding system in Iran. For this purpose a six period OLG Models have been designed and simulated. The simulation results of the specified model show that, the consumption of all generations has increased and the saving of individuals and, consequently, capital accumulation in the economy is decline due to these reforms; the result of these changes is the decline in total production of economy. Based on these results and the widespread recession in the country's economy, it is suggested that policymakers do not resort to structural reforms and transition to funded system.

Abstract         This paper examines an optimal fiscal policy model in the presence of agents heterogeneous in a dynamic stochastic general equilibrium framework. Therefore, the presence of heterogeneous agents in the model led to create limitation that will be call government preference. The role of these preferences and tendency of the Government to the poor or the rich group can change the results of optimal policies on the economy. By using a dynamic stochastic general model, the role of government preferences tendency was been surveyed. The results indicate that in these models, the role of government expenditure financing through available taxes in the policymaking system, is partly dependent on the government preferences tendency. On the bases of the results, it is suggested that separating the government preferences and tendency in relation to the poor and the rich. Manuscript profile
