The book highlights the risks associated with investing in multimillion-dollar projects. Paradoxically, the budgets of all large-scale projects at the planning stage are underestimated, and investments usually do not pay off. As a result, the total financial costs for the construction of such projects exceed the initial budgets several times, and the projects themselves become unprofitable. Why is this happening and who benefits? Should multimillion-dollar projects, the burden of which is borne by ordinary taxpayers, be controlled by the state or should they be managed by private companies? What are the technologies for risk analysis and large-scale project planning? The paradoxes of megaprojects are revealed by the example of leading infrastructure projects in Europe, such as the Channel Tunnel connecting France and Great Britain, transport links between Eastern Denmark and continental Europe, between Sweden and Denmark.
