The Agency Cost of Internal Collusion and Schumpeterian Growth

This paper analyses the link between the internal organization of the firm and the growth process. We present a Schumpeterian growth model in which monopoly firms face agency costs due to collusion between managers inside the organization. These costs affect incentives to invest and the rate of innovation in the economy. When collusion is self-enforcing, higher growth and more creative destruction shortens in turn the time horizon of colluding agents in the organization and makes internal collusion more difficult to sustain. We analyse this two-way mechanism between growth and agency problems and show how the transaction costs of side-contracting within the firm and the growth rate of the economy are simultaneously derived.     

Characteristics of consumer law

This paper analyzes elements included in the formulation of a theory of consumer law, which while derived from several different initiatives, remains an autonomous legal discipline. In constructing the model the author establishes an alternative way of viewing the consumer. This subjective approach focuses directly on the consumer and his role in the production — distribution — trade — consumption cycle. The individual consumer must be viewed as a member of a larger group. Consumers have collective interests, distinct from general public interests, which must be recognized. The author uses this model to examine policies aimed at promoting consumer interests on the Belgian economic scene and at the European Community level. The author places increased emphasis on the social aspects of consumer law and supports combining an adaptive approach with a more participative legal strategy.

Besonderheiten des Verbraucherrechts

Zusammenfassung Der Beitrag analysiert die Elemente einer Theorie des Verbraucherrechts. Dabei wird Verbraucherrecht bei aller Vielgestaltigkeit und Pluralität als eigenständige rechtliche Disziplin betrachtet. Bei der Entwicklung seines Modells folgt der Autor einer neuartigen Sichtweise des Konsumenten. Dieser subjektive Ansatz konzentriert sich unmittelbar auf den Konsumenten und seine Rolle in dem Kreislauf, der durch Produktion, Distribution, Handel und Verbrauch gebildet wird. Der einzelne Konsument muß als Mitglied einer größeren Gruppe gesehen werden. Konsumenten haben kollektive Interessen, die nicht mit allgemeinen öffentlichen Interessenlagen übereinstimmen; diese Besonderheiten kollektiver Verbraucherinteressen müssen beachtet werden. Der Autor benutzt sein Modell zur Prüfung von politischen Strategien zur Förderung des Verbraucherinteresses im ökonomischen Bereich sowohl auf nationaler Ebene in Belgien als auch auf der Ebene der Europäischen Gemeinschaft. Er betont besonders den sozialen Aspekt des Verbraucherrechts und plädiert für eine Verbindung eines adaptiven Ansatzes mit einer partizipativen Strategie.

A link between complete models with stochastic volatility and ARCH models

In this paper, we propose a heteroskedastic model in discrete time which converges, when the sampling interval goes to zero, towards the complete model with stochastic volatility in continuous time described in Hobson and Rogers (1998). Then, we study its stationarity and moment properties. In particular, we exhibit a specific model which shares many properties with the GARCH(1,1) model, establishing a clear link between the two approaches. We also prove the consistency of the pseudo conditional likelihood maximum estimates for this specific model.Received: December 2002Mathematics Subject Classification: 90A09, 60J60, 62M05JEL Classification: C32This work was supported in part by Dynstoch European network.

The effects at home of initiating production abroad: evidence from matched French firms

Based on matching techniques in combination with a difference-in-difference estimator, this paper estimates the effects at home of initiating production abroad through the establishment of a foreign production affiliate. The analysis covers manufacturing and service firms active in France during the period 1987–1999. We show that the motivation to start producing abroad is an important determinant of its impact at home. Market-seeking foreign direct investment (FDI) in manufacturing is associated with significant scale effects, resulting in job creation. By contrast, factor-seeking FDI in manufacturing has no significant effect on employment. However, there is some evidence that this type of FDI is associated with technology effects, in the form of greater capital-intensity and efficiency, as well as larger exports. Finally, FDI in service sectors is associated with significant positive employment effects, presumably reflecting the importance of the market-seeking motive in these sectors.     

Social Media in Organizations: Leveraging Personal and Collective Knowledge Processes

By using social media, many companies try to exploit new forms of interaction, collaboration, and knowledge sharing through leveraging the social, collaborative dimension of social software. The traditional collective knowledge management model based on a top-down approach is now opening up new avenues for a bottom-up approach incorporating a more personal knowledge management dimension, which could be synergized into collective knowledge using the social-collaborative dimension of social media. This article addresses the following questions: (1) How can social media support the management of personal and collective knowledge using a synergetic approach? (2) Do the personal and collective dimensions compete with each other, or can they reinforce each other in a more effective manner using social media?

Our findings indicate that social media supports both the personal and collective dimensions of knowledge, while integrating a social collaborative dimension. The article introduces a framework that classifies social software into four categories according to the level of interaction and control. With certain tools, individuals are more in control. With other tools, the group is in control, resulting in a higher level of interaction and a diversity of knowledge and mindsets brought together. However, deploying and adopting these new tools in an organizational context is still a challenging task for management, owing to both organizational and individual factors.     

Do reputation feedback systems really improve trust among anonymous traders? An experimental study

Feedback systems are claimed to be a crucial component of the success of electronic marketplaces like eBay or Amazon Marketplace. This article aims to compare the effects of various feedback systems on trust between anonymous traders, through a set of experiments based on the trust game. Our results indicate that trust is significantly improved by the introduction of a reputation feedback system. However, such mechanisms are far from being perfect and are vulnerable to strategic ratings and reciprocation. Our findings indicate that some changes in rating rules may significantly improve the efficiency of feedback systems, by avoiding strategic rating or reciprocation, and hence stimulate trust and trustworthiness among traders. In particular, a system in which individuals are not informed of their partner's rating decision before making their own decision provides better results, both in terms of trust and earnings.     

Moment conditions for Almost Stochastic Dominance

This study establishes necessary conditions for Almost Stochastic Dominance criteria of various orders. These conditions take the form of restrictions on algebraic combinations of moments of the probability distributions in question. The relevant set of conditions depends on the relevant order of ASD but not on the critical value for the admissible violation area. These conditions can help to reduce the information requirement and computational burden in practical applications. A numerical example and an empirical application to historical stock market data illustrate the moment conditions. The first four moment conditions in particular seem appealing for many applications.     

Corporate hierarchies and international trade: Theory and evidence

Corporate organization varies within countries and between countries. We develop a theory which explains the variation in levels of decentralization across firms and links it to the trade environment that firms face. We introduce firms with internal hierarchies in a Melitz and Ottaviano (2008) model of international trade. We show that international trade increases the conflict of interest between CEO/owners and middle managers within firms and these eventually lead to decentralized corporate hierarchies. We test the theory with original data on the internal organizations of 2200 Austrian and German firms and find that the empirical evidence is consistent with the model's predictions.     

Digital touch in sponsorship: Getting closer to the brand through virtual reality

Supporters are consuming more and more sporting events through digital platforms. Brands should adapt to these new consumption patterns in order to strengthen their connection with their customers. Today, researchers and practitioners can create more interactive and enjoyable experiences through virtual reality (VR) applications. Through two studies conducted on VR during sporting events, we show that mentally representing the touch experiences of players on the field reduces the psychological distance between the supporter and the player, which strengthens the supporter's attachment to the team and, through the same attachment, to the sponsor (Study 1). We also highlight that these positive effects of VR compared to real touch (using a player's jersey) is linked to the improvement of immersion, which stimulates touch imagery (Study 2). We discuss the implications of this research for theory and practice in the sports business and other sectors.     

The effect of the informal economy on bilateral exports from sub-Saharan African countries

The purpose of this study is to analyse the impact of the informal economy on bilateral exports in sub-Saharan African countries. We use a gravity model, to which we add indicators of the informal economy and indicator variables for different economic regions. The study used Pseudo-Poisson Maximum Likelihood (PPML) and Heckman estimation techniques on data from the period 2002–2018. The results show that the informal economy has a negative impact on bilateral inter-community exports and a positive impact on bilateral intra-community exports. These results thus support the idea that the informal economy can accelerate the integration of regional economic communities and ultimately facilitate the establishment of bilateral export free trade areas at the continental level.
