Digital strings are not visible, but affect all economic segments. This
book studies the phenomenon of digitalization with the instruments of
economics in order to explore the interdependencies between
digitalization, economic policy, and macroeconomic variables of open
economies. Digitalization is separated into the three components
networks, IT services, and digital goods which are then incorporated
into macroeconomic models of trade theory in open economies. This
approach allows to formally describe the cross-effects between
digitalization and macroeconomic variables of a country. Specifically,
it is used to analyze interdependencies between macroeconomic variables
and networks, IT services, and digital goods, and to determine the
challenges of digitalization for economic policy and regulation.
