The question that is considered by researchers in the field of knowledge-based economy is that among the factors affecting intangible investment, does information and communication technology have a heavier weight than the rest of the factors? In this study, using the Corrado,Hulten and Sichel (CHS) approach, the measurement of intangible investment is calculated. In their research, intangible investment has been divided into three major parts: computer information, innovative assets, and economic competencies. Then these three components are divided into nine parts. In this article, we select the component of information and communication technology, which is the first component of intangible transitory capital, and its effect on Total Factor Productivity(TFP) has been investigated. The field of study is manufacturing industries with a four-digit economic activity classification code for employees of ten and above during the years 1996 to 2018. Using panel data and GMM, the productivity function was estimated for manufacturing industries. The results of this research show that ICT has a significant role on the productivity of all production factors, and its coefficient is higher than other intangible investment components.

This article examines the theory of network-based economics (two-sided markets) and considers payment cards in Iran as a case study. Based on the monthly data of the Central Bank of Iran and the payment cards of electronic networks in Iran (SHAPARAK) from Dec. 2014 to March 2019, demand elasticity and monopoly power have been estimated. The results show that the elasticity of the cardholder and the card acquirer with respect to the interchange fee rate is 0.55 and nearly 1 (1.04), respectively. These results show that the cardholders have smaller elasticity to interchange fee compared to acquirer of payment cards. The estimated market power indicates that the payment card network in Iran is highly monopolistic. The payment card platform in Iran (SHAPARAK) does not impose its market power on the buyer side (card holders) and subsidizes them in order to create balance in transactions, but this platform impose exclusive power on merchant side (card acquirer) of payment cards. With this policy, card holders are attracted to the market which increase trading on the platform and platform profits. In general, on the buyer side of Iran payment card we have P = MC but on the merchant side P> MC. Therefore, the regulatory authorities in Iran must regulate SHAPARAK market power.
