Economics and Policy of Sustainable Infrastructure Development
Public infrastructure decisions operate at the intersection of capital markets, regulatory discretion, and political constraint, yet are routinely governed by static cost projections and fragmented accountability. Despite their long-term economic footprint, infrastructure projects are often justified through narrow cost-benefit analyses that discount externalities, ignore future adaptation burdens, and exclude system interdependencies. Procurement frameworks reward short-term bids over lifecycle resilience, while permitting processes are shaped more by political cycles than technical merit. Institutional silos between transport, energy, and water sectors prevent integrated planning, compounding inefficiencies and locking in suboptimal asset configurations. Funding mechanisms rely heavily on debt issuance without internalizing sustainability risk or aligning repayment timelines with asset degradation. As sustainability becomes politically polarizing, infrastructure investment is increasingly vulnerable to policy reversals, stranded asset risk, and credibility erosion in fiscal planning. Understanding these distortions is critical to revealing how structural misalignments in infrastructure policy contribute to systemic underperformance and long-term public cost inflation.
