The pandemic has had many tragic impacts, and the economic effects are secondary. But they are enormous. The IMF expects global economic activity to decline on a scale not seen since the Great Depression, with 170 countries seeing income per capita decline this year. There have been striking changes in the value, volume and direction of trade. WTO expects world merchandise trade to fall by between 13 and 32 per cent in 2020, with exports from North America and Asia hit hardest. There have also been changes in the relative importance of different forms of infrastructure. Take airlines for instance. Passengers are vanishing, flights are cancelled, and this means that air freight capacity is also reduced, because much air freight has actually been carried in passenger planes. However, some airlines are now using passenger planes to carry freight. Rail is also beginning to come into its own: trains are now carrying the post from China to Europe. A 12-14day journey is a lot quicker than sending goods by sea, especially when demand is high. Another vital infrastructure, telecommunications networks, is under pressure. Voice has seen a resurgence, and network disruptions have been reported across Europe. With remote working, as well as the general population staying at home, the strain on internet services is severe. Video streaming has been reduced in technical quality in order to relieve the pressure on the systems. (As for the quality of the films themselves, this is the same as it was.) And some further pressure on the system is on hold for the moment: there is a global shortage of webcams.
