This paper studies the relation between inflation rates and its uncertainty by using Markov-Switching regression model and monthly data of consumer price index during 1990:01-2012:09 in Iran. Inflation uncertainty is estimated by using Generalized Autoregressive Conditional Heteroskedastisity (GARCH) model. The empirical results of Markov Switching Auto Regressive (MSAR) model represent the presence of two clearly differentiated regimes over the entire Sample. The first regime corresponds to a high level inflation rate, low volatility, and the second regime corresponds to low level inflation, high volatility. The use of Markov-Switching Regression Model indicates that the increase of inflation rate will be associated to higher uncertainty according to both regimes.   Manuscript profile

By using SD approach in this study, we have developed a dynamic model for the future of Iranian tourism industry and simulated it during 2007-2025. Besides, to understand the dynamics involved, the purpose of this study is to forecast the industry’s future and to observe the requirements to get the objectives in the horizon of 2025. The model designed includes three main sub-systems, namely; the demand for tourism, tourism activities, and tourism capacity building. By Vensim software, the simulation results of the model explain that, if the current rates of capacity development, advertisements, and human resource development activities continue in this industry, then, we will absorb only a demand about 5.5 million tourists in 2025, that is, well below the standard of 20 million tourists per year in the horizon of  2025. The results of the simulation reveal that, to reach the tourism objectives planned, firstly, 3 sub-systems mentioned above must be coordinated and worked well together, and secondly, some prompt actions should be planned to boost the effectiveness of advertisement, the training of workforce in this regard.
