Social Cost Benefit Analysis of HL-LHC
Andrea Bastianin e Massimo Florio. Working paper CERN: Future Circual Collider, Accelerators and Storage Rings
“We present a Social Cost–Benefit Analysis (CBA) of the High Luminosity upgrade of the Large Hadron Collider (HL-LHC), assessing its economic costs and benefits up to 2038. The Net Present Value (NPV) of the HL-LHC project is positive at the end of the observation period. The ratio between incremental benefits and incremental costs of the HL-LHC with respect to continue operating the LHC under normal consolidation (i.e. without high-luminosity upgrade) is slightly over 1.7, meaning that each Swiss Franc invested in the HL-LHC upgrade project pays back approximately 1.7 CHF in societal benefits. Simulations based on 50000 Monte Carlo rounds show that there is a 94% chance to observe a positive NPV (i.e. a quantifiable economic benefit for the society). The attractiveness of CERN for Early Stage Researchers (ESR) is key for a positive CBA result. Given that benefits to ESRs are the single most important societal benefit, CERN should invest more in activities facilitating the transition to the international job market. Technological spillovers are another very important ingredient in the CBA evaluation of CERN research infrastructures. Relations with firms in the supply chain and development of Information and Communication Technologies (ICT) are strategic levers CERN should use to boost these social benefits. Cultural effects, especially those related to onsite visitors, have a great development potential for generating societal benefits. This part needs to be quantified in greater detail to understand, how this benefit potential can be further increased efficiently in cooperation with the host states.”
