This report aims to assess the impacts of Performance-Based Incentives (PBIs) within IDB Invest’s Blended Finance portfolio, with a focus on gender-related PBIs. Through a qualitative assessment of the portfolio, seven case studies were conducted with IDB Invest clients. The objective was to gain insights into the impact of IDB Invest’s PBI and gender-smart Technical Assistance (TA) program on gender equality outcomes. The case studies aim to explore internal and external changes resulting from PBI implementation, understand the design and implementation of the gender incentive and TA, and identify both success drivers and constraints affecting PBI implementation.
