Impact of ICT diffusion on the interaction of growth and its volatility: Evidence from cross-country analysis

Abstract

There is a large body of research investigating the impact of information and communication technologies (ICT) on economic growth; however, the empirical evidence on growth and its volatility simultaneously driven by ICT diffusion has still remained scarce so far. To fill this void, system two-step generalized method of moments (S-GMM) estimator and a new proxy capturing the product of growth and its fluctuation is employed to determine the nexus between ICT penetration and the interaction of growth and its volatility. Using a comprehensive panel of 122 economies covering the period 2000–2019, we find that all proxies for the ICT revolution show positive impacts on the product of growth and its volatility. This means that an increase in ICT diffusion could lead to both higher growth and lower growth volatility. To offer robust and consistent results, ICT growth and its volatility nexus are confirmed through several econometric techniques such as panel quantile regression, the control of fixed effects, alternative measure for the interaction between growth and its fluctuation, and across countries with different national incomes. The research could give rise to use of this proxy for the product of growth and its volatility with inverse hyperbolic sine transformation in the empirically econometric model for the future studies.
