Macroeconomics: UK economy, IB Economics

We had a lunchtime discussion about the CMA decision to block the proposed merger between Microsoft and Activision. We wondered whether there was an interesting microeconomic/macroeconomic trade-off.

Was it feasible that the CMA's decision was appropriate from a Microeconomic perspective, in that the merger could be anti-competitive and result in a welfare loss, but that the Macroeconomic consequences, in terms of reducing inward investment, and FDI in the tech sector could be worse than this. 

This article investigates this: there are some interesting bits of economics in here, not least the perception that "while Britain is a good place to start, it's a much harder place to scale up".
