Paper analyzes major bottlenecks to private sector development in sub-Saharan Africa using novel methods based on firm-level data.
Employs both perception-based and proxy-based methodologies, including principal component analysis.
Identifies and measures seven key obstacles to development.

Perception vs. objective measures:
- Firms frequently cite infrastructure deficiencies as their primary concern (perception-based).
- Proxy-based analysis identifies corruption followed by financial constraints as the most severe impediments to firm growth (objective measures).
Firm-size heterogeneity:
- Small and medium-sized enterprises face disproportionate challenges compared to large firms.
- Disproportionate challenges are especially pronounced regarding financial access and human capital limitations.
Implication of divergences:
- Significant divergences between firms' perceptions and objective measures of business constraints highlight the need to reconcile subjective and objective diagnostic tools when prioritizing reforms.

Need for targeted, context-specific policy interventions that address the objective constraints facing different types of firms across diverse economic environments in sub-Saharan Africa.
Policy design should account for:
- The prominence of corruption as an objective bottleneck.
- Financial constraints, particularly for small and medium-sized enterprises.
- Human capital limitations affecting smaller firms.
- The mismatch between perceived constraints (infrastructure) and measured constraints (corruption, finance), implying multi-pronged approaches that address both visible infrastructure needs and less visible institutional barriers.
