Dominant Currency Paradigm - An interesting progress in open economy macroeconomics after IS-LM-BoP

Does it matter if the exporters/importers of a country show preference for a certain currency while invoicing the trade? I had dabbled with this few years ago  here , which was based on the Dominant Currency Paradigm presented by Gita Gopinath, Casas The expanded theory titled " Dominant Currency Paradigm " (DCP) was published at the AER in 2020 and the corresponding replication code with data is made available here .  DCP is a significant development after Mundell-Fleming's model using IS/LM/BP curves which has been a workhorse model for decades. Mundell-Fleming (and the Devereux model) uses bilateral exchange rates to arrive at equilibrium rates, whereas DCP takes into account the additional factor that countries may use a third currency as invoicing currency while trading bilaterally. For example, traditional Mundell Fleming model for trade between India and Japan would use INR/Yen pair to understand disequilibrium whereas the actual invoicing of this trade may

Fourth industrial revolution and India's demographic challenge

Klaus Schwas coined the term 'fourth industrial revolution' to describe the confluence of emerging technology breakthroughs, covering wide ranging fields such as artificial intelligence, robotics, telecommunication revolution such as 5G, the internet of things, driverless vehicles, 3D printing and additive manufacturing, nanotech, biotech, materials science, energy storage and quantum technology. On the surface, it appears to be the next logical step from the third industrial revolution where electronics and IT were leveraged for production and service delivery. However, as Schwas argues, the growth of these in future would lead to exponential impact on various spheres. The velocity, scope and impact of these changes may take directions that may not be wholly predictable, affecting all fields from agriculture, education, trade, warfare, manufacturing and everything in between. There is a good (and urgent!) reason why policymakers should be abreast of developments in more than
