[F]inally, linking that into the reorganization of the ... [I]n many cases, unless the crisis really persists for 3, 4, 5 years... as soon as things become okay people will just say "Well, let's forget about it because reorganizing the value chain requires investment, hard work... Let's just go back to the old ways." So it's not certain... that... reorganization will happen, and even if it...[does], it will happen only in limited areas... [E]ven if the US wants to bring all the lost manufacturing production in... key sectors back home, it cannot do it. ...[T]hey don't have the supply network. They don't have the correct infrastructure. They don't have the necessary supply of technicians. ...[E]ven if it wanted, Apple cannot bring factories in China to California to make the s.

[A] lot of developing countries are dependent on primary commodities, and especially those that are dependent on oil have been devastated because oil demand has collapsed as a result of the pandemic. ...[I]t is important for developing countries to diversify... production structure to avoid this... Easier said than done... Ecuador, under Rafael Correa, tried for about 10 years to shift the production structure. The pull of the oil was so strong that by the end of his term, it was a bit lower, but the dependence was still very high. ...[I]n the next few years, because of the pandemic... primary commodities... (material products) might actually become more important in relative terms... [T]he overall level of demand will be lower... but... in relative terms, at least, primary commodities are going to fare better than... services. The point... is... what happens in the long run will really depend on what you do with the income that you earn from primary commodities. ...[L]uckily a lot of countries have been thinking about industrializing using more active ... so something might happen in some countries and... some... are already doing... very impressive things... Ethiopia has converted a lot of its garment making facilities—basically investments from east Asia: South Korea, China, Taiwan—into factories producing [medical] personal protection equipment... [I]t has converted... passenger jet planes into cargo planes and is doing more cargo business.

[T]he few changes that this crisis has brought about... their consequences, and what countries do in order to deal with them will depend on how long this crisis continues, and how effective the solution[s]... are likely to be. These are things that I don't have the expertise to predict: ...When is the vaccine coming out ...if there will be an effective cure..? [I]s there going to be a similar outbreak? ...I'm just ...assuming that this crisis will probably last another two, three, maybe five years... [A] lot of society will try to go back to the pre-pandemic way as much as possible, but... if we are going to be—even if we wanted—able to go back to the old ways... it will take a few years.
