Controlling the business cycle and minimizing the inflation gap are considered as two major goals for monetary policy. Hence, the policymaker will be able to make more decisive decisions with an awareness of the dynamic relationship and causal relationship between these two variables. Accordingly, the present study uses a discrete and continuous wavelet transform to provide a new understanding of the relationship between these two variables in Iran's economy during the years 1990:2 – 2017:1. According to the results of the research, in the short-run (less than one year), the causal relationship has been bidirectional and procyclical. In the medium run (1 to 4 years), the causal relationship is countercyclical and from the inflation gap to the business cycle. In the long run (4 to 8 years), the business cycle is leading, and the two variables are in phase. Besides, the relationship between variables is highly unstable over time and depends on different scales. Therefore, inflation in Iran's economy is not merely a monetary phenomenon, and in the medium-term is affected by changes in the real sector. According to the results of the research, for the output and the inflation to be stable, it is recommended that the policymaker take both goals simultaneously.

Purpose- This study aimed to analyze the effects of saffron cultivation on the quality of life of rural households in Rostaq Dehestan in Khalilabad county. Design/methodology/approach- This is an applied study based on a descriptive-analytical method used to examine the understudy parameters. The data were collected from 337 sample households based on field studies and by the Cochran sampling method. Then, the data were also collected based on selected indicators and using a household questionnaire. The validity of the questionnaire was evaluated by the university professors of geography and rural planning and agricultural promotion and training. The validity coefficient of the questionnaire was obtained using the SPSS software of 0.85. Kendall's statistical tests and one-way variance analysis was used in SPSS software to analyze the collected data. Findings- The research findings show that Neghab village with a similarity index of 0.48 has the greatest impact of saffron cultivation on the quality of life of the households among the villages of Rostaq Dehestan. On the other hand, the results of the Kendall test confirmed the relationship between saffron cultivation and quality of life with 99% confidence. Moreover, the results of one-way ANOVA showed that the economic dimension among other effective dimensions of the saffron cultivation on the quality of rural households is more pronounced. Research limitations/implications- The lack of access to statistical information when visiting the Agricultural Jihad of Khalilabad, Khalilabad Governorship, the Natural Resources Administration of Khalilabad, as well as completing the questionnaire depending on the issue at the village level are some of the challenges of the present study. Practical implications- According to the research findings, solutions to promote and train the ways for production and productivity of households in this village are recommended for the cultivation of this supra-strategic product (Saffron). Originality/value- The present study is important since it focuses on the impact of saffron cultivation for improving the quality of life of rural households with respect to the income generation process of this product.
