Who can use
the payment?

A government pays an outstanding claim. The contractor receives the money, but a financier has first call on it and an old supplier is still waiting. To understand what the payment can support now, follow who can actually use the cash, in which order, and at what point earlier claims are exhausted.

My research, Paying on Time: Receivable Finance, Trade Credit, and Public Settlement, examines that sequence after a public receivable has already supported credit. It asks when contractual priority changes the best recipient of a fixed settlement budget, holding the existing claims and productive opportunities constant.

The answer includes an important baseline: changing priority does not always change the allocation. The research identifies both a condition under which the orders agree and a more demanding setting in which they lead to different choices.

A receipt passes through several accounts

A public claim may have helped finance activity before the government paid it. If the receivable was assigned to a financier, the eventual receipt may retire an outstanding principal balance before it becomes free working capital for the contractor.

That retirement reduces debt and transfers resources to the financier. It does not make money disappear, and it does not imply that the earlier borrowing was wasteful. The question at settlement is a later one: which current uses become available after the contractual payments have occurred?

In the finance-first baseline, the model separates three stages. First comes financing principal. Then come legacy obligations, including old supplier balances. Finally, retained funds can support current activity, subject to productive capacity and the payments generated by that activity.

Old claims and current productive links therefore need separate descriptions. Paying a former supplier can release cash somewhere other than the original contractor. A contractor already at capacity may still transmit funds to a creditor able to expand.

Start with the case where priority makes no difference

The controlled comparison uses three firms: a public contractor, its old supplier, and a debt-free alternative recipient. The supplier can also support activity through a current productive connection. The government allocates a fixed cash budget between the contractor and the alternative.

The comparison holds the financing balance, supplier claim, budget, information and productive opportunities fixed. Only the order of the financier and supplier claims changes.

Under the paper’s maintained opportunity ranking, the supplier’s early productive route is less valuable than the debt-free alternative, while the contractor’s completed productive opportunity is more valuable. In that class, finance-first and supplier-first priority select the same optimal allocation, apart from ties.

This result disciplines the mechanism. A different legal order can change the timing of creditor receipts without necessarily changing which recipient the model selects. The productive opportunities available to those creditors are central to the answer.

When an early supplier opportunity changes the choice

The reversal appears under further conditions when the supplier’s early productive route is valuable enough to outperform the alternative. Supplier-first payment then creates a useful small tranche before the contractor has cleared all its old claims.

The paper supplies an exact constructed example. With a total budget of 2.7 model units, finance-first priority allocates all 2.7 to the contractor. Under supplier-first priority, the optimum pays only 0.5 to the contractor, allowing that amount to reach the supplier, and directs the remaining 2.2 to the alternative recipient.

The budget and opportunities are identical across the two comparisons. The difference is who has usable funds early enough to exploit an opportunity. Meanwhile, the contractor’s own activity still begins only after the same total stock of old claims has been discharged.

The example establishes a conditional allocation result. It does not establish that subordinating financiers is generally preferable or costless: consent, contract repricing, future credit and bank redeployment would require their own analysis.

The size of the payment matters

A small payment may be absorbed entirely by a senior balance. A larger payment may exhaust that balance and reach a productive use. Larger still, it may encounter a capacity ceiling that makes another recipient more attractive.

A single marginal response at the starting point cannot capture all those transitions. Nor can gross payments through a chain be counted as fresh productive resources every time cash changes hands. The model distinguishes debt cleared, cash retained and activity financed before comparing allocations.

That distinction connects the theory to a concrete empirical question: can a disclosed payment sequence show the exhaustion of a financing stock and the resulting change in the receipt left after principal repayment?

An observed financing waterfall

The paper examines disclosures from a Chinese renewable-energy infrastructure fund whose underlying project used recourse factoring against public subsidy receivables. This is a specific national-subsidy financing arrangement, rather than a representative sample of local procurement arrears.

Four receipts in the third quarter of 2025 total CNY 464.5465 million. Their disclosed allocation schedule reconciles with CNY 428.3530 million of factoring-principal outflow in the subsequent quarterly report. The principal-only residual is CNY 36.1935 million.

The sequence is informative because the residual changes as the finance balance is exhausted. The first two allocations leave no principal-only residual. A later receipt clears the remaining principal and leaves a residual; the final receipt is wholly outside that principal sweep.

One constant retained fraction cannot describe all four allocations. The quarterly reconciliation supports the aggregate principal accounting, while exact bank-transfer dates and the absence of unreported offsetting transactions remain separate evidential questions.

Connect the evidence to the right claim

The disclosures document the finance-first schedule. They do not observe supplier-first renegotiation, measure the supplier’s productive return, track subsequent bank lending, or estimate a Chinese output effect. The residual may also face interest and other uses before it supports activity.

The fiscal comparison likewise begins with an existing obligation. Paying it earlier uses cash now while changing a future payment schedule. That differs from treating settlement as entirely new spending, and from counting cancellation of a receivable as current output.

The research’s practical contribution is an explicit route from contractual priority to usable funds and conditional productive opportunities. For financial intermediation and supply-chain research, that route makes the right questions visible: which claim is being extinguished, who receives the cash, which constraint changes, and what evidence establishes its next use?
