  • Competing on Quality - Literature Review
    Download the report (pdf 2.4Mb)
    The quality of goods and services is of key importance for customers in many markets and suppliers often compete to win customers' business not only on price but also on quality and other non-price dimensions. This report reviews what the economics literature has to say about the link between competition and quality, in particular for the healthcare sector.

    The report reveals that the economics literature provides only limited insights into the impact of competition on quality when businesses are free to set both prices and quality levels. In contrast, the literature suggests a positive relationship between competition and quality when prices are regulated, provided that the regulated prices are set at a level so as to sufficiently cover costs.

    For the healthcare sector, the report reviews empirical studies on the actual impact of competition on the quality of healthcare services and the behavior of patients, GPs and healthcare providers in the English NHS, finding outcomes that are consistent with the predictions of the economics literature.
  • Cost pass-through: theory, measurement, and potential policy implications
    Download the report (pdf 2.9Mb)
    Cost pass-through arises when a business changes the prices of the products or services it supplies following a change in its costs. The Office of Fair Trading (OFT) has commissioned RBB Economics to undertake a comprehensive review of the literature on cost-pass through as pass-through is relevant across much of the OFT's work. The report highlights that cost pass-through is likely to differ according to a number of factors (such as the responsiveness of demand and supply conditions a business faces) and contains guidance for practitioners dealing with pass-through related issues.

  • Partitioned pricing research
    Download the covering report (pdf 193kb), behavioural experiment report (pdf 1.5Mb) and the literature review (pdf 1Mb).
    This piece of economic research seeks to explore how partitioned pricing, which is the practice of splitting the price of a good or service into multiple components, affects the consumer decision-making process. Partitioned pricing can either occur with a 'drip', where an additional fee is revealed at a later stage in the buying process than the base price, or without a 'drip'. The OFT has previously analysed partitioned 'drip' pricing and consequently this research focuses on partitioned pricing without the 'drip', where the base price and the additional fee are presented at the same time. As part of this research, the OFT commissioned Partitioned Pricing: a behavioural experiment (pdf 1.5Mb) which examines the impact on consumer decision-making of different forms of partitioned pricing.  Further, in order to consider the experiment in the context of previous research, we also conducted a literature review (pdf 1Mb), which summarises the theory of partitioned pricing and its possible impact on consumer decisions, and in turn consumer welfare.
  • The impact of reverse-fixed payments on competition
    Download the report (pdf 3.1Mb)
    The OFT commissioned this report to identify the impact of reverse-fixed payments such as shelf slotting allowances, listing fees and pay-to-stay fees on competition. To achieve these objectives, more than eighty articles, working papers, and surveys were reviewed. Besides providing a comprehensive and up-to-date review of the academic literature the report identifies a number of indicators which can help to categorize the likely competitive effects of such payments.
  • The economics of online personalised pricing
    Download the report (pdf 572kb)
    The OFT has published a report on the results of a call for information regarding the personalised pricing online (pdf 605kb). In support of this, we have published an economic report that summarises the wide and varied literature on the economic effect of price discrimination online and sets out a framework intended to guide a practical analysis of price discrimination. The report shows that price discrimination with competition is likely to be beneficial to consumers in most, but not all, cases. We identify various market characteristics that make price discrimination more likely to be harmful. You can also download a short note of a public round-table (pdf 79kb) we had regarding this research.
  • Anti-Competitive Effects of RPM (Resale Price Maintenance) Agreements in Fragmented Markets, prepared for the Office of Fair Trading by Greg Shaffer (February)
    Download report (pdf 1.9Mb)
    It is widely recognised that RPM agreements can facilitate collusion or exclude potential competitors where there is significant market power at one or both levels of the vertical supply chain. This report evaluates, and extends to increasingly fragmented markets, a number of models which have posited that networks of RPM agreements between multiple manufacturers and retailers may also soften competition where there is no market power. The report also assesses the practical implications of the findings for the OFT and identifies key characteristics that might indicate when consumer harm is more likely.

  • The Economics of Secondary Product Markets
    Download report (pdf 1.4Mb)
    Where there is competition in a primary market, but a lack of competition in a secondary market, for example due to consumers being partially or completely locked in to the secondary product following the purchase of the primary product, then the market power in the secondary market may result in the firm earning high profits. However, these high secondary profits may induce additional competition, and therefore lower prices, in the primary market. This has been termed a "waterbed effect". A complete waterbed effect occurs when all additional secondary market profits are competed away in the primary market. The report considers whether, when and to what extent high secondary market profits can be expected to be offset by low primary market pricing and identifies a number of observable factors which may indicate whether the waterbed effect is more or less likely to be complete.
  • Price Relationship Agreements A report prepared for the OFT by Lear
    Download report (pdf 2.8Mb)
    PRAs are arrangements linking one supplier's price to those charged to other customers or by competitors. Examples of PRAs include 'most favoured nation' clauses (MFNs), price guarantees, and meeting competition clauses. The report provides a comprehensive literature review of PRAs, bringing together different economic theories of harm and efficiency motivations for the different types (and critiques of these theories) and drawing out possible policy implications.
