In order to identify the potentials of different regions for the purpose of regional planning, the comparative advantage theory can play an important role. Comparative advantage is an important economic index for the production as well as export and import to measure the relative priorities of a region in comparison to others. This paper deals with the value added comparative advantage of sectors and activities in the Khorasan region (i.e. Razavi and Northern as well as Southern provinces) and compare them to other provinces of the country. We have used the most recent regional accounting data published in 2006 as well as the latest edition of system of national accounting (SNA93) in order to measure the so-called Revealed Comparative Advantage (RCA) for Khorasan region between 2001-2005. the results indicate that the region enjoys comparative advantage in agriculture sector and industries related to agricultural activities such as food industries whereas it has not revealed comparative advantage in industry as a whole. We also found that the region has comparative advantage in activities related to tourism industry (i.e. hotels and guesthouses).therefore, it is suggested that the region concentrate on investment in tourism related activities and also on agricultural products processing industries.

Recently, there has been a focus, among many economists such as Ronald Coase, Douglas North, and Oliver E. Williamson, on recognizing the institutional and structural conditions of societies and their impacts on economics and economic variables.This study has been aimed at the influences of economic, political, and social structures on fluctuations of exchange rate during a period of thirty years (1973-2001). To do the task, we have firstly referred to various existing theories concerning factors involved in exchange rate fluctuations, and have reviewed the exchange rate changes throughout the intended period. Next, we have analyzed exchange rate changes through a historical study, and have recognized the most important economic, political, and social structures in Iran in order to make a comparative exploration of exchange rate changes. The results have shown that the mentioned structures have, in many ways, influenced the exchange rate fluctuations in Iran. The obtained primary findings were included in a questionaire in order to test hypotheses of this study in accordance with the attitudes of Iranian economic authorities and academicians. Through doing the various coefficient tests including Kendall’s Tau-b, Kendall’s Tau-c, Gamma, and Spearman tests, all three intended hypotheses show the existence of a significant relationship between economic, political, and social structures, and exchange rate fluctuations. This study has concluded a summary, policy recommendations, and final considerations

A binary probit model is an appropriate method to analyses household and individual characteristics influencing women’s employment. Since this model is a non-linear probability model, its interpretation is not so easy as linear models. In this paper, after making the probit model of women’s employment based on data on 4220 married women at 20-50 age group, the model has been interpreted using probabilities predicted by various quantities of explanatory variables and changes in probabilities. Findings show that although, in comparison between urban and rural areas, direction of relation of the explanatory variables with women’s employment probability is the same, the extent and form of this relation (being either linear or non-linear) in most cases is completely different. In addition, it follows that the increase in the spouse’s annual income and in the household’s miscellaneous incomes could leave a considerable negative effect on the married women’s employment probability. Meanwhile, we concluded that the employment probability increases significantly with increase in age and educational levels.
