Start-ups have emerged as key drivers of economic growth and job creation, and are often a catalyst for radical innovation. Young firms indeed account for about 20% of employment but create almost half of new jobs on average across OECD countries, and innovation by young firms significantly contributes to aggregate productivity growth, accounting for half of it in the United States.
During the coronavirus (COVID-19) crisis, start-ups have continued to play a critical role for economies. Some innovative young firms have reacted fast and flexibly to the pandemic, and have been critical in helping many countries shift towards fully-digital work, education, and health services, and have provided innovations in medical goods and services.
