The current study investigates the effect of implementing six development plans on multidimensional inequality in Iran. To this end, the multidimensional Gini Index of inequality by Assis Kumar Banerjee (2010) for dimensions such as welfare, education, housing, health, and social welfare (aggregation of other dimensions in household expenditure-income basket) calculated for years 1984-2021 and their performance was evaluated. The results of this study showed that the implementation of the development plans led to an inequality increase. Among these six plans, implementing the first plan had an incremental effect on the inequality value. The third and fifth socio-economic plans have a decremental impact on inequality at a significant level of 5%. Also, there was no difference between implementing and not implementing other plans on the inequality value. Also, the results indicated that given the comprehensiveness and multidimensionality of the development plans, inequality did not experience a constant trend and had mild fluctuations in the urban and rural areas and the whole country. Moreover, at the end of the sixth development plan, the inequality value (0.825) reached a value higher than the beginning of the first plan (0.771) in 1989.

This study intended to review of the evolution of the theories and policies related to international trade, ranging from classic and neo-classic theories to recent trade theories that have been already applied by several developed countries for international trade. To that end, at first neo-classic trade theories, ranging from reciprocal demand theory to resource endowment one, along with their experimental applications as well as logical critics against them are offered. then, complementary discussions on Linder’s overlapping demand and the role of geography and transportation in trade, vertical intra-industry trade, horizontal intra-industry trade are followed. It finally ends by emphasis on the theories of Ozawa’s flying geese model and strategic trade. Research findings show that economic theories initially focused on inter-industry trade and then expanded with an emphasis on intra-industrial theories. Among these, the role of geography, trade within the vertical and horizontal industry is important. According to the research results, theories of international trade initially emerged with the presentation of classical theories and then matured with neoclassical theories. But the evolution of theories entered a new phase after the introduction of the role of geography and economies of scale with Paul Krugman's article on “trade and geography” in the form of new trade theories (NTT). Also, the progress of international trade theories occurred with the introduction of theories into trade cycles and strategic trade issues.

Purpose: The purpose of this research was to present a customer experience management model in five-star hotels. Method: In this research, the researcher has used a database approach , and in the first study, he used the database approach based on the Ostrous approach to identify the components of the research. The tool used for collecting the required data in the first study, the protocol and in-depth interviews with five-star hotel managers and its customers in the country has been purposefully chosen and analyzed. Findings: the researcher conducted fifteen interviews in theoretical literature, and also has done axial and selective coding and then presented the results in the form of six main dimensions. Conclusion: The researcher has presented his research in the form of a model including six main dimensions, verbal advertising, service quality, new norms, customer service, event marketing, customer experience and thirty three sub-dimensions. Research findings show that improving the customer experience is the main objective for many people who work in hotels and hospitality industries.
