Online reviews are a vital input for consumer decision-making. However, reviews are easy to manipulate, and widespread fraud is undermining credibility and raising the issue of consumer protection.

Facebook, Google, and Amazon utilise reviews to improve the consumer experience, but also to sell advertising to businesses and to address fraud. These companies leverage their data superiority to better utilise reviews on their platforms, and possess a competitive advantage, versus sites like TripAdvisor, Yelp, and eBay.

Demand for expert opinion remains strong, yet is supplied only by publishers and Which?, a small segment in terms of share of traffic relative to platforms.

In China, Alibaba and Tencent compete for food delivery to expand access to a fast-growing source of mobile user data, using their chat and wallet super apps to funnel customers to their food delivery apps

In the West, the rivalry is direct between the food delivery apps – Just Eat, Uber Eats, and Deliveroo – and the costs of last-mile delivery dissuade challengers

In the UK, Amazon will change the game if it succeeds in its proposed purchase of a minority stake in Deliveroo, which Uber failed to buy last year. Progress on the merger of Amazon and Deliveroo is suspended by the regulator

Governments and operators have come under increasing pressure to exclude Huawei’s 5G equipment from national networks, with justifications usually kept vague and wide-ranging rather than specific, and no evidence provided.

Given the role of Huawei’s 5G equipment in the network and the extent of existing testing and checking, realistic security risks that apply to Huawei and not to all other equipment suppliers are hard to conceive.

The risks of any ban are however very real; with Huawei one of only three global-scale telecoms equipment suppliers, and the preferred early choice for 5G radio equipment in the UK, removing this choice will massively increase costs and delay roll-outs of cutting-edge connectivity.

Many European telecoms operators are pursuing a fixed/mobile convergence strategy on the pretext that the addition of mobile reduces churn. We see no evidence of churn reduction from this strategy

Discounts required to encourage take-up of fixed/mobile services are often value-destructive, even before competitor reaction: a 10% bundle discount necessitates a 2ppt improvement in churn to wash its face economically. M&A premia on the basis of convergence synergies raise the hurdle even higher

Most UK operators offer very limited discounts on fixed/mobile bundles for now, sensibly focusing on enhanced services. Vodafone is the most aggressive, albeit less so than it is elsewhere. All UK players should hope that it stays this way
