Horizontal mergers have a large impact by inducing a long-lasting change in market structure. Only in an industry with substantial entry barriers is a merger not immediately counteracted by post-merger entry. To evaluate the duration of the effects of a merger, I use the model of Abbring and Campbell (2010) to estimate demand thresholds for entry and for exit. These thresholds, along with the process for demand, are estimated using data from the ready-mix concrete industry. Simulations predict that a merger from duopoly to monopoly generates between nine and ten years of monopoly in the market. (JEL G34, K21, L12, L13, L41, L61)

‘Mergers and acquisitions’ discusses mergers and acquisitions. While of potential benefit to society, mergers, takeovers, share acquisitions, and joint ventures also affect the market structure, and at times may reduce competition. When markets become more concentrated following a merger, we move further away from a competitive market structure to a structure in which market power might undermine the competitive process. To address this risk, the competition agency must assess the impact of the transaction. There are important procedural differences between the European administrative system and the US system in terms of the appraisal of mergers and acquisitions. Other types of mergers include: horizontal mergers, vertical mergers, and conglomerate transactions.

This article discusses the relationship between industrial concentration and the presence of black-owned firms. Strong evidence is found that more monopolistic industries have a smaller black presence. This demonstrates that the monopolistic industries in which black workers are known to face the worst discrimination are also the industries in which blacks face the highest structural entry barriers as entrepreneurs. Indeed, entry barriers may cause the monopolistic conditions which allow discrimination while simultaneously frustrating the entry of black entrepreneurs.

Quality certification programs help consumers identify high-quality products or sellers in markets with information asymmetries. Using data from eBay UK's online marketplace, we study how certification's impact on demand varies with market- and seller-level attributes, exploiting variation in sellers' certification status within groups of near-identical listings. The positive effects of eBay's “top rated seller” certification are stronger for categories with few other certified sellers, in more competitive markets, and for sellers with shorter records of past performance. These findings indicate certification provides more value when certification is rare, the product space is crowded, and for sellers lacking established reputations. (JEL D12, D82, L15, L86)
