Cash flow is the life blood of the construction industry, goes the mantra. Construction projects often have long supply chains. When cash stops flowing down the chain, businesses can fail. There is all too much recent evidence of this.

Someone in the chain (say, a main contractor) could seek to provide in a contract that it does not have to pay the party below (subcontractor) until it has been paid by the party above (employer). This is a 'pay-when-paid' clause.

The European Commission has published a report by external consultants (Oxera), Should aid be granted to firms in difficulty, a study on counterfactual scenarios to restructuring state aid? It is intended to inform the Commission of the consequences for intended recipients and their relevant industries if aid is not given, including whether the aid will, in fact, save jobs and economic activity.
