Paper notes

The corporate taxation of green and brown firms in South Africa

South Africa's largest emitters face corporate income tax burdens that fall as carbon intensity rises, effectively subsidising pollution through the main business tax. Linking emissions data to tax records for the country's top 300 emitters, researchers find that carbon-intensive firms pay systematically less than their greener counterparts, and the implicit per-tonne subsidy embedded in the corporate income tax is roughly ten times larger than South Africa's effective carbon tax rate of USD 2.4 per tonne of CO2-equivalent. Three channels drive the gap: deductibility of debt interest, profit shifting through tax havens, and uptake of tax incentives, with green incentives disproportionately captured by brown firms. For South African reform, the finding reframes climate policy as a corporate tax design problem: raising the headline carbon price will have limited bite while the income tax base continues to reward emissions-heavy production.

Trade integration and firm performance: Evidence from South Africa

The 2013 South Africa–China Strategic Trade Agreement prompted South African firms to reorient their input sourcing toward Chinese capital goods, raising firm-level capital-labour ratios over the following decade. Drawing on microdata spanning ten years and exploiting the agreement's quasi-exogenous timing, the analysis finds that firms recorded gains in sales and value-added consistent with a scale effect, which appears to have offset the labour displacement typically expected from capital-labour substitution. Aggregate employment remained stable, and wages trended modestly upward. The results run counter to standard trade-theoretic predictions that cheaper imported capital necessarily erodes domestic employment, pointing instead to complementarities between capital deepening and output expansion in manufacturing. For South African reform debates, the evidence suggests that reducing trade costs on capital intermediates offers a plausible lever for industrial expansion without the labour market losses that often stall liberalisation efforts.

Idea of the week

Water is the binding constraint, and the arithmetic is unforgiving: a R90 billion bulk infrastructure backlog, Lesotho Highlands Phase 2 slipping again, and a Vaal system absorbing pollution loads and extraction volumes it was never engineered to carry. The Bulk Water Infrastructure Investment Programme is the vehicle through which that backlog is meant to be retired — now routed through the National Water Resources Infrastructure Agency, which absorbed the Trans-Caledon Tunnel Authority in mid-2025.

The institutional logic is defensible; the transitional cost is not trivial. Six appearances before the Water and Sanitation Committee have surfaced a consistent pattern: the NWRIA Amendment Bill supplies the legal scaffolding, but engineering, procurement and project-finance capacity have not migrated across at the pace the balance sheet requires. Feasibility sits at 3, which is roughly where one would expect an idea whose binding constraint is less about money than about the number of people in the country who can actually close a concessional loan for a dam. Status remains under review, and the backlog compounds whether the Agency is ready or not.

The committee returns to the file on 22 September 2026. Watch two things. First, whether NWRIA tables a staffing and delegations schedule — not another organogram, but named authority for procurement decisions above the R1 billion threshold. Second, whether Lesotho Highlands Phase 2 receives a revised completion date that Treasury is willing to countersign. Absent both, the Programme remains a legislative achievement in search of an implementing institution, and the Vaal keeps doing the arithmetic for us.

Constraint check-in

As of October 2026, water remains the binding constraint on growth, settlement expansion, and industrial siting. System losses persist above 40% in several metros, Vaal augmentation milestones continue to slip, and bulk reticulation backlogs are now the rate-limiter for housing and reindustrialisation pipelines rather than generation capacity. The Portfolio Committee on Water and Sanitation returned to the file this week, with the Bulk Water Infrastructure Investment Programme tabled under review. Its feasibility score of 3 reflects the familiar gap between pipeline design and the municipal absorptive capacity required to execute it.

The near-term question is whether the Programme survives committee scrutiny with ring-fenced conditional-grant mechanics intact, or is diluted into equitable-share top-ups that have historically failed to reach bulk assets. Watch the committee's treatment of implementation agent arrangements in the next sitting: delegation to Water Boards versus municipal execution will determine whether the Programme shifts the constraint over the MTEF or merely re-labels existing allocations.
