Abstract
The aim of this study is to review the causal relations between TFP growth and inflation as one of the attracting issues in Macroeconomic literature. For the first time in Iran, we have used the wavelet decomposition technique to study this relation. Both TFP growth and inflation series between 1960-2006 are decomposed up to three levels. Our analysis of causality relations between all the composed and decomposed series shows that though no statically meaningful effect between original series has been proved, there are some negative relations between decomposed series in first and second level. Moreover, our study reveals some previously unknown spillover effects between various frequencies of both series as explained in paper. Finally, on the basis of relations founded between decomposed series of inflation in different frequencies, we introduce a new instrument to measure the volatility of inflation.

Abstract
The concept of “Innovation” has changed considerably in recent years. According to new theories, the innovation emerges in a system of interrelated elements and determinants during which the idea changes to a commercialized output or process. The literature on the innovation has concentrated mainly on various aspects of innovation chain separately. In this paper we tried to investigate the general effects of the whole elements of the innovation chain simultaneously. These elements are: R&D expenditures, physical capital formation, human capital and patent filling (residence and non-residence). We utilized multivariable time-series methods including cointegration and vector error correction model (VECM) to assess the long-run effects of innovation elements on total factor productivity in Iran. Results show that excluding the human capital variable, other elements of innovation chain have positive effects on TFP among them, residence and non-residence patent filling having the normalized long-run coefficients of 0.58 and 0.48 respectively, are the most important factors affecting TFP in Iran.

Abstract
Undoubtedly, one of the ways to realize the knowledge-based economy is to improve the Total Factors Productivity through the expansion of innovative activities and the absorption of the hidden knowledge in imported technologies. What facilitates this process is the appropriate institutional quality and the targeted use of globalization capacity in different dimensions. In this regard, this research, with the approach of panel data and the Method of Generalized Moments (GMM), investigates the mutual effect of globalization and innovation on the productivity of the total factors in two groups of selected science-producing countries with per capita income above 20 thousand dollars and selected countries Science producer with low per capita income paid $20,000 during 2011-2019 period. The results show that the mutual influence of globalization and innovation have had a positive and significant effect on the productivity of the total factors in both groups of selected countries with different estimated coefficients. The same is the case with the effect of the control variables of economic incentives and institutional regime and training and development of human resources, while control variable of economic freedom has a positive and significant effect on the total factor productivity index in selected science producing countries with high per capita income and in selected science producing countries with low per capita income. According to the findings of the research, it can be said that globalization by itself cannot be considered as a factor in improving the productivity of factors. Rather, the targeted use of human capital capacity in the context of appropriate institutional quality can benefit from the positive benefits of globalization and economic freedom in order to improve the productivity of all factors.
