Wider economic benefits (WEBs) are claims, often large claims, for additional economic benefits over and above transport user benefits. This paper reviews the four main forms of WEB: agglomeration economies, the value of additional output in imperfectly competitive markets, labour supply effects, and various possible impacts of transport infrastructure on economic development, sometimes described as place making
