Incumbency advantage and its value

Markets with network effects are typically concentrated. The aim of this paper is to discuss some recent work on “incumbency advantage.” That is, the fact that firms already installed generate higher profits than entrants even if the latter offer identical or even better terms (in terms of price and quality) to consumers. In particular, we review recently known sources of the advantage and potential mitigating factors and point to a number of open issues.     

Female participation in African labor markets: The role of information and communication technologies

This article investigates the effects of information and communication technologies (ICT) on female labor force participation in a sample of 48 African countries. We specify and estimate linear regression and dynamic panel data models with fixed effects (FE) and system-generalized method of moments (SYS-GMM) estimation over the period 2001–2017. The three main results are that ICT use (mobile phone and internet) significantly stimulates female labor force participation in Africa; this effect is enhanced by financial development and female education; the effect of ICT on female employment in Africa is strongest in the industrial sector. These results remain robust to the provision of social, cultural, and institutional variables.     

WHICH AGGLOMERATION EXTERNALITIES MATTER MOST AND WHY?

This paper revisits the ongoing discussion on the importance of agglomeration externalities – specifically specialization, diversity and competition effects – that may contribute to innovation, productivity and urban employment growth. Previous meta‐analyses suggested that the evidence on agglomeration externalities is strongly context‐specific. Expanding an earlier analysis of 31 articles, we seek to draw in this paper more robust conclusions by means of the statistical evidence for agglomeration externalities presented in 73 scientific articles, all building on the seminal work of Glaeser et al. (1992). Our results confirm that the heterogeneity among studies is huge and can only be partially accounted for by means of an ordered probit analysis. Additionally, some evidence of publication bias is found. We conclude that the conventional lines of inquiry in this literature may now have reached strongly diminishing returns. New lines of inquiry, using rich micro‐level data on firms and workers, dynamic general equilibrium models at the macro level, more attention for spatial and temporal variation in the impacts of agglomeration, and further investigations into the spatial scope of externalities are promising avenues for further research that can enhance our understanding of how agglomeration externalities continue to fuel our increasingly urbanized world.     

Book reviews

Abstract

This article examines the cultural field of fitness as a network of producers, consumers, products and practices that has developed around the care of the body through physical exercise. Drawing on a thematic text analysis of US exercise manuals, the paper focuses on how the commercial fitness field naturalizes associations between physical exercise and leisure, and between leisure and self‐work. In particular, the analysis examines three themes and their relevance to our broader understanding of leisure in contemporary consumer society: the management of leisure time; the use of leisure for self‐investment strategies; and the promotion of consumption as the framework for leisure and an accompanying notion of pleasure. The fitness field casts light on how leisure more generally is constructed as a sphere of obligations to make productive use of one’s time, to improve one’s body and self, and to do so through the wares of the consumer marketplace. The cultural imaginary of leisure as a time of freedom from work and responsibility is thus recast, in an age of individualization, as a time of freedom to accomplish the work of self‐production.     

Perceived trust in contractual channel dyads: an exploratory investigation of Finnish food retailers

Distributor firms have found long-term contracting an effective means of gaining competitive advantage. To realize these benefits, the alliance should involve trusting others. However, contracts can also be one-sided rather than reciprocal, favouring the larger business partner. Should trust develop naturally where there are formal contracts defining the terms of the relationship? And what inducements should a supplier take to gain retailers' trust? The trade-off is further complicated when the retailers operate in a small market with few suppliers and high barriers to entry. This study focuses on these questions. We use original field data from Finnish food retailers who have signed a written agreement with their focal wholesaler. We find that maintaining autonomy increases trust in the relationship. We also find that regular communication in the dyad and balance between perceived rewards and contributions are associated with higher levels of trust. In turn, intrachannel competition strongly reduces retailers' trust in the dyad.     

Advertising and the Department of Energy's Campaign for Energy Conservation

Abstract

Motivating consumers to conserve energy has proven to be a difficult task in the United States. One tactic that has been used on a limited basis by the Department of Energy is paid advertising. This paper examines the role of conservation within the country's broader energy problems, delineates several consumer issues that affect the success of government conservation programs, discusses the controversy surrounding the use of paid advertising to promote consumer conservation efforts, and describes those DOE programs that have used paid advertising as an integral component of conservation program strategy.     

Technical and vocational teaching and training in Gabon: how future teachers build their vocational identity?

The professionalism of teachers is based on three levels of expertise: mastering academic knowledge, mastering the teaching of this knowledge and mastering the role played by teachers in schools. For each of these levels, each student during the teacher training courses has his own understanding. This understanding influences their perception of the job of teacher and thus their attitude towards their training. Efficiency of this training could be evaluated through the evolution of this understanding. The experimental part of this study will involve looking at this evolution with students from the ENSET in Libreville at the beginning of the training course, the end of the first cycle and the end of the second cycle. Data collected shows that training does not really produce the desired results for a university vocational teacher training course for technology education.
