What countries built

The move, and what it needed

Paraguay used an APP concession to bundle design, financing, construction, maintenance and operation of a national corridor, moving some delivery and lifecycle obligations to a private special-purpose company while the ministry retained contract oversight.

Preconditions

• A procurement and contract-management authority able to specify service levels over a multi-decade concession
• Traffic, toll and payment data strong enough to allocate demand and revenue risk transparently
• Public capability to monitor construction quality, renegotiate only under clear rules and enforce maintenance after opening

Where it travelled: Public-private partnerships travel only when the state can remain a demanding contract manager. Ruta PY02 is useful evidence of scale and institutional ambition, but its long concession also makes monitoring and renegotiation part of the capability being tested.

The move, and what it needed

Paraguay combined a recurring transfer with family guides, monthly payment and a georeferenced beneficiary register, then pushed bank access into a programme that had previously paid less frequently and reached families unevenly.

Preconditions

• A social registry and field network able to identify, revisit and update vulnerable households
• Payment rails that can reach rural and Indigenous families without making bank access a new exclusion test
• Health, education and social-work services capable of turning a transfer into sustained household support

Where it travelled: Social-protection systems travel when the registry and payment rail travel with the benefit. Paraguay's redesign shows how frequency, field accompaniment and financial inclusion can be treated as one delivery problem.

The move, and what it needed

Paraguay made the tax document a machine-readable event: SIFEN set a national standard, validated documents centrally and combined a mandatory calendar for larger taxpayers with a free tool and electronic signature path for smaller ones.

Preconditions

• A tax authority with legal power to set the document standard and phase in compliance
• Reliable identity, signature and validation services that firms can integrate at low cost
• A support and exception process for small businesses with limited connectivity or software capacity

Where it travelled: Electronic invoicing travels as a state-business coordination project, not merely an IT purchase. Paraguay's combination of a central validation rail and a free small-firm route is the part worth comparing.

The move, and what it needed

Paraguay sustained a technically complex binational asset through a permanent operating institution, shared dispatch and long-horizon maintenance rather than treating the dam as finished when construction ended; the national grid could then convert a cross-border project into domestic energy security.

Preconditions

• A durable treaty and governance structure able to resolve operating and revenue disputes across two states
• Engineering, maintenance and safety institutions that preserve performance over decades
• Transmission and utility capacity able to absorb a large, hydrology-dependent supply stream

Where it travelled: Large infrastructure lasts when the operating institution is designed as carefully as the concrete. Itaipú is a useful benchmark case because its delivery story is four decades of binational maintenance, not only its original construction.

The move, and what it needed

Paraguay attempted a multi-municipality bus rapid transit corridor through a public works contract, but weak design integration, contract management and escalation left paid works disconnected from a functioning service and triggered an ex-post prosecution rather than an operating system.

Preconditions

• A corridor design agreed with the municipalities, operators and affected communities before civil works are certified
• Contract-management capability able to test whether each payment creates a usable part of the service
• A credible stop-and-correct process that can surface an unviable design before sunk infrastructure and litigation dominate the response

Where it travelled: Failed transport projects are useful capability evidence when the failure is written as a delivery problem rather than a scandal alone. Metrobús shows why integration, certification and the ability to stop matter as much as the initial capital commitment.
