As COVID-19 vaccination ramps up worldwide, understanding factors that may lead people in low- and middle-income countries (LMICs) to reject COVID-19 vaccination is of global concern, as lags in vaccination could facilitate global spread of virus variants.

Policymakers in countries dominated by small and medium-sized firms face challenges in spurring them to grow and hire more workers. In particular, it has been difficult to distinguish entrepreneurs with potential for growth from their “subsistence entrepreneur” peers.
