As the actual cost of corruption is likely to be impossible to calculate (as explained in Cost of Corruption), it is useful to consider the possible costs of corruption on a project on a hypothetical basis.
The benefit of doing so is that it illustrates, when you take several possible different corrupt acts into account, the compounding effect of corruption on project costs.
GIACC has therefore developed two examples of the cost of corruption on hypothetical infrastructure projects. These show the compounding effect of corruption on project costs using two different scenarios.
In view of the difficulty in calculating the actual cost of corruption in the infrastructure sector, attempts have been made to estimate this cost.
A common form of estimate uses the average percentage of project value that is assumed to be required to be paid as a bribe in a particular country in order to win a main contract. For example, it could be said that in Country X, bribes are normally in the region of 5% of the main contract price for public sector projects. This estimate is then used to provide an estimated global figure of the loss to corruption by taking a similar percentage of total infrastructure expenditure worldwide.
However, even as an estimate, this is highly unlikely to be representative of the full cost of corruption on a particular project, let alone nationally or globally. It may be only a small part of the equation. In particular, it takes no account of the bribes that may have been factored into contract prices further down the contractual chain in order to win sub-contracts and supply contracts. The cost of these bribes is normally included in the contract prices all the way up the contractual chain. As a result, a bribe of 5% paid to win a main contract will be calculated on a build up of sub-contract prices which themselves may already include bribes.
The overall loss to bribery on award of all the project contracts could therefore be far higher than the 5% paid at main contract level.
This can be demonstrated in the following example where the bribe paid by the contractor to win the main contract was 5%. However, if each sub-contractor and supplier all the way up the contract chain also paid a 5% bribe, and included this bribe in their price, then the overall loss to the public purse due to bribery would be 16% (i.e. far higher that the 5% estimate).
Contractual chain | Contract price with bribe (i.e. other sub-contract price + own price + bribe) ($) | Contract price without bribe ($) |
Sub-sub-sub-sub-contractor | 0m + 20m + 5% bribe = 21m | 20m |
Sub-sub-sub-contractor | 21m + 20m + 5% bribe = 43.05m | 40m |
Sub-sub-contractor | 43.05 + 20m + 5% bribe = 66.2m | 60m |
Sub-contractor | 66.2m + 20m + 5% bribe = 90.5m | 80m |
Main contractor | 90.5 + 20m + 5% bribe = 116m | 100m |
The above example assumes that each sub-contractor is obliged to pay a bribe of 5%, and has included the cost of the bribe in its own contract price. This then means that the project owner (who is ultimately the public in the event of public sector projects) eventually bears all those bribery costs. However, to the extent that this does not happen, then the relevant contractor or sub-contractor will itself suffer the cost of the bribe.
The above method of estimate also does not cater for other types of corruption that may take place during the project (e.g. corrupt over-design, corruptly defective work, bribes paid to obtain certificates and permits etc.).
Corruption can occur all the way down the contractual chain. A major infrastructure project may have thousands of contractual links, between the main contractor, sub-contractors, sub-sub-contractors and suppliers.
At the top of the chain, the main contractor may pay US$30 million as a bribe to the government representative in return for the award of a major infrastructure project.
At the bottom of the chain, a sub-sub-contractor or supplier may make a payment of US$500 to the procurement manager of a company in exchange for a minor sub-contract or supply contract.
Fraud (such as false or inflated claims) can also have an enormous impact on the overall contract price. It can occur at every contractual link.
The cost of the bribes and false claims will often form part of the final contract price, and have a cumulative effect. A bribe or false claim at the bottom end of the chain may be passed all the way up the chain, with an overhead cost added at every level, magnifying the cost of the initial bribe or fraudulent act.
While the costs and effects would vary tremendously from project to project, the following hypothetical scenario illustrates the cumulative effect of bribery and fraud on an infrastructure project.
Assume that a power station would cost $100 million if properly engineered, if awarded after a genuine arms-length open-market tender, and if managed in an environment free from bribery and fraud. The following example analyses what could happen to the $100 million price if the environment was not free from bribery and fraud. The calculations and methodology are deliberately simplistic.
In consequence of the assumed facts above:
