Cost Benefit Analysis

Cost Benefit Analysis (CBA) involves a systematic evaluation of the costs and benefits, from a societal perspective, of a project, policy, or program. The method can be used to assess the impact of projects that have been completed in the past, or alternatively a forward-looking assessment can be made to examine the expected net returns from projects that are yet to be initiated.

The economics of responding to drought in Greater Sydney

Sydney Water engaged Synergies to develop an economic framework for quantifying the risks, costs and benefits of a drought management strategy for Greater Sydney. The framework examines the optimal sequence of new water supply projects as Sydney’s storage levels drop. The optimal strategy is one that avoids the risk of storages falling below critical levels (and triggering the need for very significant water restrictions), while minimising the cost of investing in capital projects that may ...
