Capacity is more than an announcement

A proposed project, a financing commitment, construction and commercial operation represent different stages of investment. Productive capacity also depends on complementary inputs, customers and operating conditions. Research follows these stages when evaluating investment claims or industrial support.

Additionality and public support

Public support can alter whether, where, when or how an investment occurs. These are distinct effects. A project announcement after a subsidy decision does not establish the investment that would otherwise have occurred.

Evaluation requires a defined counterfactual and an account of selection, timing and displacement. The report on industrial investment additionality develops the evidence needed to distinguish those effects.

Comparative Study

Two routes to industrial expansion

Infrastructure coordination and resource processing expand industry through different mechanisms. Indian planning evidence and Indonesia’s downstream strategy are compared through complementary inputs, domestic value creation and explicit project accounts rather than export or construction totals alone.

Comparative Study

Manufacturing capability in aging economies

Japanese manufacturing strategies and German training evidence highlight the interaction of automation, specialized skills, and supplier continuity. A production-line example shows how bottlenecks, maintenance knowledge, and quality determine whether investment preserves capability as the workforce ages.

Economic Explainer

Capacity, production and utilization

Installed capacity, actual production and economically sustainable output measure different constraints. A plant-level example separates engineering limits, operating schedules and commercial conditions before interpreting capacity utilization or announced industrial investment.

Supply resilience and concentration

A concentrated supply chain can reflect scale, specialization or a constraint in a critical input. Supplier counts alone do not establish substitutability. Qualification, transport, tooling, intellectual property and the time needed to expand output determine the practical response to a disruption.
