Sunk Costs, Contestability, and the Latent Contract Market

The idea that an industry with sunk costs may be contestable even in the absence of long-term contracts has received little attention informal economic theory yet is sometimes popular among practitioners. This paper formally illustrates the argument. In an infinitely repeated game, there exists a class of contestable outcomes in which the monopolist sells only on the spot market and charges low prices along the equilibrium path to prevent customers from resorting to long-term contracts. The crucial test for contestability is the level of transaction costs in the latent contract market.     

The impact of vertical integration on inventory turnover and operating performance

This paper investigates how vertical integration may influence inventory turnover and firm operating performance. A causal model is developed to investigate the effects of vertical integration on three types of inventory, namely raw materials inventory (RMI), work in progress inventory (WIPI) and finished goods inventory (FGI). The model tests the interactions between inventory types and the consequences of inventory turnover performance on various aspects of firm performance including costs and profitability. In particular, path analysis supports systematic differences with respect to how vertical integration affects RMI, WIPI and FGI. Vertical integration has a positive effect on RMI and FGI turnover but no significant effect on WIPI turnover. FGI contributes to a reduction in supporting processes costs which causes an improvement in return on sales (ROSs). Vertical integration impacts ROS directly.     

Valuation effects of mergers and acquisitions in freight transportation

This study investigates valuation effects of mergers and acquisitions in the freight transportation industry. It is found that mergers and acquisitions create synergistic gains, especially tender offers, consistent with the view that freight transportation mergers and acquisitions occur for synergistic reasons rather than management’s desire for empire building or perk consumption. Both target’s and bidder’s shareholders are better-off, but most of the synergistic gains accrue to the target’s shareholders. Targets’ valuation effects are greater for vertical rather than horizontal mergers, indicating a positive valuation for firms that control and manage a more extensive supply chain. The bidders’ wealth effects are greater for friendly mergers. Overall, the findings have important implications for professional practice and the development of the theoretical literature.     

Developing the evidence base of patient and public involvement in health and social care research: the case for measuring impact

While patient and public involvement (PPI) in health and social care research has progressed successfully in the last decade, a range of difficulties with the evidence base exist, including poor understanding of the concept of impact, limited theorization and an absence of quantitative impact measurement. In this paper, we argue that a paradigm change towards robust measurement of the impact of involvement in research is needed to complement qualitative explorations. We argue that service users should be collaboratively involved in the conceptualization, theorization and development of instruments to measure PPI impact. We consider the key advantages measurement would bring in strengthening the PPI evidence base through a greater understanding of what works, for whom, in what circumstances and why.     

Import Protection, Export Promotion, and Product Positioning

The argument that import protection may lead to export promotion is examined from the marketing standpoint. The model shows that protection allows home firms to cover a larger portion of the domestic market than they otherwise would and to target market segments that are closer to the mainstream. At the same time, foreign competitors are forced to retreat to more idiosyncratic market segments of narrower appeal. Thus, protection gives home firms a product positioning advantage over their foreign rivals; this advantage translates into higher market share and profits—not only in the protected home market, but also in export markets.     

Boards,ownership structure,and involuntary delisting from the New York Stock Exchange

This study examines whether the likelihood of becoming involuntarily delisted from NYSE is associated with a firm’s board of directors and ownership characteristics. To this end we compare 161 firms that were delisted from NYSE between 1998 and 2004 to a set of industry and size-matched control firms. Consistent with our expectations, we find that the likelihood of delisting is related to a firm’s governance characteristics. Our results on the importance of the board of directors are new to this setting and add to a large body of evidence linking corporate boards and ownership characteristics to corporate performance.     

Self-Regulation,Innovation, and the Financial Industry

The paper shows that the presence of continuous innovation may be one of the driving forces of self-regulation. In an infinitely repeated game, there exists a class of subgame perfect equilibria in which the self-regulatory organization, or SRO, pursues socially desirable objectives along the equilibrium path to stave off government intervention. Delegating regulatory authority to the SRO eliminates certification-related delays in the adoption of new services, fosters innovation and leads to higher social welfare.     

Cross-Listing, Bonding Hypothesis and Corporate Governance

Abstract:  This paper examines the relationship between cross-listing and corporate governance for Canadian firms, that were cross-listed on US stock exchanges during the period 1997–2003. We find that cross-listed firms have more independent boards and audit committees after the listing relative to a non-cross-listed matched sample of firms and relative to the pre-listing period. Moreover, cross-listed firms experience changes in their ownership structure after the listing. Finally, we provide evidence that the sensitivity of the relation between cross-listed firm valuation with audit committee independence and ownership structure becomes more important after the listing. The results are robust after adjusting for various firm risk characteristics. Overall, the results are consistent with the literature on the bonding role of cross-listings on US stock exchanges.     

Downstream Vertical Foreclosure and Upstream Innovation

I examine a link between downstream foreclosure and upstream innovation. The crucial ingredient of the model is the presence of dynamic economies of scale upstream in the form of competition in R&D. The reason an upstream supplier has a captive buyer is to force rival suppliers to incur the disadvantages of low-scale production and discourage them from innovating. The downstream buyer is offered favorable terms and is “convinced” to sign an exclusive supply contract and accept captivity. In this context, downstream foreclosure may reduce consumer welfare.
