Is self-supply in the relevant market?
Vertically integrated firms supply upstream goods to their own downstream units (self-supply). At the same time non-integrated upstream firms may supply the upstream good to independent down-stream firms (third party sales). Should only third party sales constitute the market when calculating market share thresholds in State aid control, or should self-supply also be considered? This note shows that the presence of self-supply may significantly reduce the downward pressure on prices that can result from a State aid-induced output expansion. If so, self-supply should be considered in market definition.

Cost benefit analysis of regulation
When reviewing the costs and benefits of sector specific block exemptions, the European Commission and other evaluating bodies often face the problem of quantifying the costs resulting from the responses of market participants to changes in the legal framework. However, cost quantification can be avoided if there is convincing evidence that the pro-competitive effects are limited. This note proposes a simple technique to identify such evidence in the context of multi-branding in the distribution of vehicles (Motor Vehicle Block Exemption Regulation).
