Our economic expertise

Competition

We provide clients with economic advice on a wide range of competition issues.

We have advised on large mergers, including upward pricing pressure, merger simulation, efficiencies and remedy design.

We have helped clients on abuse cases where a competition authority is either already investigating or could potentially investigate particular commercial practices (e.g. excessive pricing, anticompetitive bundling, self-preferencing etc.).

We have also assisted many clients during market inquiries, looking at market definition, competition assessment and benchmarking among other things.

Litigation

Our team members have been involved in many litigation and arbitration cases around the world. This has included investor-state cases, commercial litigation and regulatory appeals. We have prepared expert reports on behalf of clients and given oral testimony.

Regulation

Our experts have advised regulatory authorities and regulated companies during critical regulatory decisions such as price controls, sector inquiries, auctions and regulatory investigations into pricing and other types of behaviour.

Policy and economic impact

We carry out policy work and economic impact studies for clients. These cover a wide range of sectors and subjects. We focus on rigorous quantitative techniques such as CGE modelling and econometric analysis of policy options.

    Public Policy

    Through Line Advisors carried out a series of studies examining the digital economy in eight countries in Africa. In each of them, we analysed the current size of the digital economy and the government’s strategy for digital development. We looked at the scope for future development of the digital sector and its potential impact on the economy as a whole. We developed a model of the mobile sector and its linkages to key other sectors of the economy and used it to analyse policy options.
