To compound the economic forecasting problem, government interventions, such as temporary income replacement programs to mitigate unemployment, may not be fully factored into projected unemployment metrics challenging the credibility of the forecast. The severity of the local lockdown seems to be the simplest key driver impacting economic expectations in the short- and mid-term, while duration of the local lockdown is driving the longer-term effects. Such forecasts may be completely unreliable as the artificial shut-down of many consumer goods and services markets has pushed the economy into a state of disequilibrium. Greater emphasis is needed on augmenting traditional data with inferences from alternative data sources.
