Government spending. This is likely to be more effective than tax cuts in stimulating the economy in the short run. Co-ordination is important, as echoed by the head of the IMF, because countries trade with each other. If one does “enough” to restore its supply chain and demand but others don’t, we will all still be stuck with the problems in supply and demand that are driving the economy down. For instance, governments can support those who have lost their jobs or are quarantined. This is arguably more pressing in the UK, where unemployment benefits are much lower as a percentage of previous income than in the OECD average. Indeed, unemployment benefits account for 34% of previous income in the UK for the first 2 months as opposed to 64% for the OECD average (https://data.oecd.org/benwage/benefits-in-unemployment-share-of-previous-income.htm). Another good move would be to increase wages for those on the front line, such as nurses, whose starting salaries took a hit in real terms after the last financial crisis (https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/819464/NHSPRB_2019_Report_Web_Accessible__1_.pdf).
