"Real-time economic indicators help better track activity in Africa"

" \n Real-time economic indicators help better track activity in Africa \n \n\n \n Economists are increasingly turning to new technologies that help track indicators such as growth and inflation in real time to sharpen their forecasts and offer better input for policymakers. \n \n\n \n Nowcasting, or forecasting of the present, is especially promising for developing economies where statistical authorities may not release indicators frequently. At the IMF, we have developed an approach that pairs high-frequency data with machine learning, a kind of artificial intelligence, to provide economic-growth nowcasts and help policymakers make better decisions. \n \n\n \n Some developing economies release key indicators such as gross domestic product with lengthy delays. That adds to challenges for setting policy in times of rapid change, such as the onset of the pandemic or outbreak of war in Ukraine, because decisions must be made without crucial data. \n \n\n \n At times like these, nowcasting can offer projections that approximate economic activity a lot more quickly than official GDP data. \n \n\n \n As the\u00a0<a href=\"https:\/\/lnks.gd\/l\/eyJhbGciOiJIUzI1NiJ9.eyJidWxsZXRpbl9saW5rX2lkIjoxMDYsInVyaSI6ImJwMjpjbGljayIsImJ1bGxldGluX2lkIjoiMjAyMjA1MjcuNTg1NDc0MDEiLCJ1cmwiOiJodHRwczovL3d3dy5pbWYub3JnL2VuL05ld3MvQ2hhcnQtb2YtdGhlLXdlZWs_dXRtX21lZGl1bT1lbWFpbCZ1dG1fc291cmNlPWdvdmRlbGl2ZXJ5In0.3ISgntQnJhJt2yDPM9hqCmY0fu3qJE2SS579dOhp2Zo\/s\/1181822789\/br\/132025920194-l\" target=\"_blank\" rel=\"noreferrer noopener\">Chart of the Week \u00a0shows, the nowcasting framework offered invaluable information for Botswana when pandemic closures hit in the second quarter of 2020.
