Reputation-based pricing and price improvements

Dealers often offer price improvements, relative to posted quotes, to their clients. In this paper, we propose an explanation to this practice. We also analyze its effects on market liquidity and traders’ welfare. Enduring relationships allow dealers to avoid informed trades by offering price improvements to clients who do not trade with the dealer when they are informed. A dealer never observes whether a specific client is informed or not but he can avoid informed orders by conditioning his offers on past trading profits. Cream-skimming of uninformed order-flow increases the risk of informed trading for dealers without a relationship. Thus, authorizing price improvements increases bid-ask spreads and impairs the welfare of investors without a relationship. It may even decrease the welfare of investors who develop a relationship as they sometimes need to trade at posted quotes. The model predicts a positive relationship between (a) the price improvements granted to a specific investor and past trading profits with this investor or (b) the frequency of price improvements and bid-ask spreads.     

A bibliometric analysis of the scientific literature on Fairtrade labelling

Since its foundation, the Fairtrade movement has attracted the attention of consumers, practitioners, media and scholars. Discussing the role that Fairtrade can play on a global yet locally rooted scale is very complex, as research reports contrasting results about its usefulness and effectiveness. This study examines scientific research on Fairtrade over the last decades by conducting a bibliometric analysis of the literature published on the ISI Web of Knowledge Core Collection, which included 876 papers by 1,293 authors in 432 journals. Results show that despite this being a relatively recent field of study, Fairtrade has been approached from different disciplines with different methodologies and objectives. The structured quantitative study of the literature enabled us to inspect how research has evolved over the years in the light of the changes faced by Fairtrade, to explore its scope in the broader field of the global market, to detect current research schools and perspectives within the network and to identify hitherto unaddressed issues and unconnected subfields.     

Service Trade and Occupational Tasks: An Empirical Investigation

Using microdata for Belgium, we investigate the relationship between changes in the task content of production and the rise in the number of service exporters. We show that occupational tasks changes display an extremely consistent relationship with participation to service exports: in sectors in which the importance of face‐to‐face communication with customers has increased, the firm‐level likelihood of entering export markets has decreased; instead, the likelihood of exporting increased in sectors in which the sophistication of production and delivery has expanded (following an increase in cognitive tasks). Moreover, our analysis suggests that the change in IT use per se does not strike as being a key underlying force behind the increase in the extensive margin of service exports. These results are robust controlling for comparative advantage, offshoring, trade liberalisation and demand shifts.     

The need to reformulate consumer protection policy

The author in these concluding remarks seeks to locate the role of soft law as an instrument for implementing active consumer protection policy in the present regulatory crisis debate. By drawing on the national and EEC structures outlined in the workshop debate, he shows that the imbalance of modern industrial societies has led to a greater need for consumer protection. State intervention becomes necessary to counter-balance the failure of the present market structures and appears to be the only means of consumers gaining market power. Almost all speakers at the workshop reacted favourably to a flexible form of regulation, but opinion seemed to be against replacing consumer policy by soft law alone.The author goes on to show how the present EEC consumer policy is merely a reflection of modern consumer law and that there are limits to Community action in this sphere, which should not be meekly accepted. The inability of the Community to reach consensus is visible in spheres other than that of consumer policy. The core issue remains one of a political approach to an economic crisis which demands more and not less regulation.The question of whether soft or hard law is the most appropriate can only be settled by the use of an appropriate instrument: soft law can only function within an environment of a minimum level of law. The pre-requisites to a system of soft law being fully effective within the Community have not yet been reached. There is a need for a revival of the consumer movement within the Community and increasing sensitivity on the part of policy makers towards consumer demands.

Zur Notwendigkeit des Verbraucherschutzes — Schlußbemerkungen zum Tagungsthema

Zusammenfassung In seinen Schlußbemerkungen geht der Autor von der Notwendigkeit aus, auf der Ebene der EG wie in den Mitgliedstaaten weitere verbraucherschützende Maßnahmen zu ergreifen. Die Referate hätten übereinstimmend ergeben, daß nicht ein Abbau von Regulierung, sondern flexible Instrumente das Gebot der Stunde seien. Nach wie vor existierten Marktversagensformen, die staatliche Intervention notwendig machten. Der Schutzbedarf des Konsumenten sei eher größer als kleiner geworden. Die Angleichungspolitik der EG müsse schon deshalb fortgesetzt werden, um Regulierungslücken zu schließen. Wenngleich die Grenzen der Handlungsmöglichkeit der EG heute deutlich seien, müßten sie gerade im Interesse der Schaffung eines Gemeinsamen Marktes überwunden werden.Der Streit um den Vorrang von Maßnahmen des hard oder soft law reduziere sich auf eine Auseinandersetzung um geeignete Regulierungsinstrumente. Ohne ein Mindestmaß an zwingendem Recht, institutionellem Gefüge und Beteiligungsrechten von Verbraucherorganisationen könne eine soft law Regulierung, etwa durch freiwillige Verhaltenskodices und Selbstkontrolle nicht funktionieren. Hierfür bestünden auf EG-Ebene bislang noch nicht die Voraussetzungen, so daß der Prozeß der Rechtsangleichung nicht nur vorangetrieben, sondern um neue Instrumente angereichert werden muß. Geboten sei eine Reaktivierung der Verbraucherbewegung in der EG.

Pricing and hedging S&P 500 index options with Hermite polynomial approximation: empirical tests of Madan and Milne's model

The universal use of the Black and Scholes option pricing model to value a wide range of option contracts partly accounts for the almost systematic use of Gaussian distributions in finance. Empirical studies, however, suggest that there is an information content beyond the second moment of the distribution that must be taken into consideration.This article applies a Hermite polynomial-based model developed by Madan and Milne (1994) to an investigation of S&P 500 index option prices from the CBOE when the distribution of the underlying index is unknown. The model enables us to incorporate the non-normal skewness and kurtosis effects empirically observed in option-implied distributions of index returns. Out-of-sample tests confirm that the model outperforms Black and Scholes in terms of pricing and hedging. © 1999 John Wiley & Sons, Inc. Jrl Fut Mark 19: 735–758, 1999     

Monitoring Policy and Organizational Forms in Franchised Chains

Franchising is nowadays a prominent way to organize the distribution sector. While previous literature suggests that monitoring issues are a critical determinant of organizational choices, it is rather silent on the optimal monitoring strategy once the organization of the chain is set. In this article, we analyze the monitoring policy of chains with both franchised and company-owned units. We develop a model in which a chain monitors its outlets under asymmetric information on local demands and managers’ efforts. We show that partial monitoring (i.e., when the franchisor monitors only a subset of its outlets) represents an optimal monitoring policy. Second, we identify the units that should be monitored. Finally, we discuss the impact of information technologies and outlet location on monitoring policy and how it may affect the proportion of franchised and company-owned units within the mixed chains.     

Globalization and the empowerment of talent

Many experts have identified globalization as the new way in which firms organize their activities and the emergence of talent as the new stakeholder in the firm. This paper examines the role of trade integration in the changing nature of the corporation. International trade leads to a ‘war for talent’ which makes it more likely that an organizational equilibrium emerges in the integrated world economy in which control is delegated to lower levels of the firm's hierarchy empowering human capital. Furthermore, trade integration is shown to lead to waves of decentralization and to convergence in corporate cultures across countries.     

New patterns of consumer protection under warranty law: Lessons from the U.S. magnuson-moss warranty act

Warranty law appears to be a relevant instrument for granting protection to consumers against product disappointment. However, empirical studies concerning some warranty markets both in the United States and in West-European countries show that there continues to be no bargaining on warranties between sellers and buyers, that the most serious risks are all allocated to the user of the product, and that consumers are generally not granted an actual opportunity of challenging a breach of warranty and getting adequate compensation for losses sustained. The Magnuson-Moss Warranty-Federal Trade Commission Improvement Act which was enacted in the United States in 1975 constitutes a first comprehensive and consumer-oriented reform of traditional warranty law. It foresees new patterns of consumer protection under warranty statutes, combining warranty substance regulation with warranty information, administration, and litigation procedures. This paper first describes the Act's major provisions; it also points out some of its deficiencies. Although criticisms are formulated against the Act's ideology or basic assumptions, it is the author's opinion that it represents a decisive step towards legislative and administrative participation in the formulation of warranties. The Act undoubtedly suggests some, though not identical, avenues of reform that legislators and authorities of European countries and confederations should now propose in order to increase consumer protection against defective or unsatisfying products.
