The Dispute Settlement Mechanism of the WTO: A Brief History and an Evaluation from Economic,Contractarian and Legal Perspectives

Any rule‐based system has to include a mechanism for the enforcement of its rules and a means for settlement of disputes about alleged violation of rules. The General Agreement on Tariffs and Trade (GATT), concluded in 1947, and its successor the World Trade Organisation (WTO) that subsumed it in 1995, embody rules governing the global trading system as specified in various agreements that their members have entered into over time. Naturally, both had a dispute settlement mechanism (DSM). It was a primarily political one in the GATT and was transformed into a largely legalistic one in the multilateral agreement that established the WTO. This paper reviews the history and evaluation of the two DSMs and examines their efficiency based on appropriate criteria. It views them from three alternative and overlapping perspectives: political‐diplomatic, legal‐economic and social. It concludes with a discussion of the unresolved problems in the operation of the WTO's DSM and the prospects of resolving them in the ongoing Doha Round of multilateral trade negotiations.     

Are share price levels informative? Evidence from the ownership, pricing, turnover and performance of IPO firms

We ask whether a firm's choice of IPO price is informative in the sense that it relates systematically to the firm's other choices and characteristics. We find that both institutional ownership and underwriter reputation increases monotonically with the chosen IPO price level. We also find that the relationship between IPO price and underpricing is U-shaped. In contrast, post-IPO turnover displays an inverted U-shaped relation to IPO price. Moreover, firms choosing a higher (lower) stock price level experience lower (higher) mortality rates. Our results are robust to controls for market liquidity and firm size, and for partial adjustment of IPO prices based on pre-market information.     

Construct validity of some unweighted product-count diversification measures

Construct validities are assessed for three simple-to-compute, unweighted, SIC-based continuous diversification measures and a recently proposed two-dimensional, SIC-based categorical diversification measure. Two of the three continuous measures are found to correspond strongly to Rumelt's categorical measures, suggesting that these two objective and easy-to-calculate measures are better suited for large sample, strategy research than has previously been assumed. No support is found for the two-dimensional measure.     

Mediating Internal Competition for Resources*

We consider a model of internal competition, where projects developed by agents with different preferences compete for resources in an organization. Allowing a manager—who has moderate preferences—to control the allocation of resources has benefits when preferences are not too diverse. In particular, the manager acts as a mediator, forcing agents to compromise when competing projects succeed, thus providing better insurance to agents and increasing their effort. Our framework provides a theoretical foundation for two influential views of a manager—as the “visible hand” that allocates resources, and as a “power broker” who resolves conflict in an organization.     

Pricing and persuasive advertising in a differentiated market

This paper examines the effects of consumer preferences, firms’ costs, and advertising efficiencies on firms’ pricing and persuasive advertising strategies. We show that as the firms’ horizontal differentiation increases, the firm with a lower value-added product tends to increase persuasive advertising, whereas its competitor tends to reduce advertising. Second, the firm receiving a favorable shock in product valuation will complement the favorable change with additional persuasive advertising rather than reduce advertising spending. Third, an equal improvement in advertising efficiency in the industry will lower the profits for both firms, whereas a decrease in advertising efficiency in the industry can benefit both firms. Fourth, a larger shock that improves a firm’s product valuation or unit cost is more likely to induce higher advertising spending in the industry. Lastly, an exogenous increase in the separation between firms’ product valuations or perceived qualities may actually reduce the price dispersion in the industry.     

Using the Analytic Hierarchy Process in house selection

The house selection process involves an assessment by the buyer of a myriad of qualitative and quantitative factors before negotiating a purchase. The complex interplay among these factors along with the limitations of humans to systematically consider the complex information set, create the potential to induce serious inconsistencies in decisions. This paper presents a formal judgmental model of the house selection process using the Analytic Hierarchy Process (AHP). The model will allow the buyer to consistently evaluate property attributes. We also present a simple extension of the model to help the prospective buyer arrive at an attribute weighted price that can be used for comparative rankings.     

Operating decisions, supplier availability and quality: An empirical study

In the just-in-time (JIT) philosophy, purchasing strategies advocate the use of fewer sources of supply to enable a firm to improve the quality of its products. However, there is paucity of empirical evidence in support of the theory. We develop a model by integrating concepts from manufacturing, marketing, and business strategy to better understand the links between operating decisions of the firm, supplier availability, and product quality. We empirically test the hypotheses using cross-sectional PIMS data. Our analysis shows that operating decisions and environmental factors such as wider product lines, lower levels of competition, and greater frequency of product changes increase the likelihood of a firms' reduction of supplier base, which in turn raises quality levels.     

New Product Development Structures: The Effect of Customer Overload on Post-Concept Time to Market

In corporate policy statements, seminars, journal articles—even in television commercials—the message comes through loud and clear: To remain competitive, we must do a better job of listening to our customers. Through close contact with customers, designers can more accurately identify market requirements, quickly refine product specifications, and thus reduce time to market. However, too much customer input can create confusion and duplication of effort, which ultimately increases time to market. In other words, some firms run the risk of over-listening to their customers. In a study of three global players in the electronic component industry, Srikant Datar, Clark Jordan, Sunder Kekre, Surendra Rajiv, and Kannan Srinivasan explore the effects of having too much input from customers. Specifically, they examine the relationship between a company's new product development structure and the volume of customer input, which in turn can affect time to market. The high-tech, fast-cycle firms examined in this study employ two distinct new product development structures: concentrated and distributed. A concentrated structure locates all product designers in one facility. This facilitates cross-product learning among designers, but limits designers' contact with customers and process engineers. A distributed structure disperses new product development among numerous manufacturing sites, giving designers close contact with customers and process engineers. However, a distributed structure limits designers' opportunities for cross-product learning. Analysis of 220 new product efforts reveals that the distributed structure offered a time-to-market advantage as long as these firms efficiently managed the level of customer interaction. When designers received input on the product design from no more than 25 customers, the distributed structure provided shorter time to market than the concentrated structure. Beyond the 25-customer level, time-to-market performance of the distributed structure degraded quickly and at an increasing rate. In such cases, more effective management of customer interaction might allow firms employing a distributed structure to enjoy the benefits not only of customer input, but also of improved coordination between product designers and process engineers.     

Concentration in ownership of plant variety rights: some implications for developing countries

This paper explores concentration levels in the ownership of intellectual property rights over plant varieties worldwide. An analysis of data for 30 UPOV member-countries shows a high degree of concentration in the ownership of plant variety rights for six major crops at the national level in the developed world. Much of this concentration has arisen owing to the rapid consolidation of the seed industry through mergers and acquisitions, especially in the 1990s. A high degree of concentration in the ownership of plant variety rights, in combination with recent efforts to strengthen plant variety protection regimes, is likely to have significant effects on the prospects for future innovation in plant breeding and the distribution of market power between companies. For developing countries, concentration in intellectual property right ownership may have important implications for the structure of domestic seed industries and access to protected varieties and associated plant breeding technologies. These implications for developing countries are likely to become apparent in the context of the rapid spread of plant variety protection and access legislation, emerging changes in the international exchange regime for plant material and liberalised investment policies permitting foreign investment in the seeds sector.
