Securing a better deal from investors in public infrastructure projects: insights from capital budgeting

The return on capital is a major contributor to the cost of design, build, finance and operate (DBFO) contracts, under which public infrastructure is financed and delivered by private companies. The article presents a method for evaluating the rates of return targeted by bidders and applies this to 10 contracts commissioned by the UK National Health Service.
