This document discusses public policy interventions to support entrepreneurs and small businesses. It outlines some typical interventions like building human capital, addressing debt and equity gaps, and supporting unemployment to self-employment transitions. It then evaluates the impacts of two UK programs: Business Link Health Checks and the Small Firms Loan Guarantee (SFLG). Health Checks provided advice and referrals, leading businesses to make improvements. SFLG addressed debt financing gaps through loan guarantees, finding supported businesses grew jobs and sales faster than similar non-supported businesses. Both programs showed positive economic returns through increased output, employment, and exports.
