Identity Building Through Mediation by African Tailors

In contemporary African cities, dressing well and wearing exclusive garments has become crucial for people in search of identity, distinction and individuality. The research presented in this article, situated at disciplinary intersections of cultural studies, fashion practices and sustainability, provides a case study of African tailors conducted in Maputo and Lisbon, with a special focus on identity building of African immigrants in Portugal. However, the role of tailors in this acculturation process has been ignored in the consumption approach to creative cities. This study is therefore also a reaction to the mainly Western world of regular couture, and to ‘creative city materials’ that focus on consumption. Instead, we emphasize the importance of African tailors who de facto shape urban experiences—visually incrementing practices—that are fundamental to the comprehension of sartorial culture, while we also allude to the complex intersections between local and global markets. In the first part of this article we describe a semi-ethnographic study among tailors in Maputo and Lisbon. The second part presents a participatory action approach that entailed developing an educational programme for African tailors where culture and creativity meet. This programme empowered tailors to tap into their cultural knowledge on tailoring and their awareness of community identity. In our study we argue that the idea of creative cities and their creative economy should be approached from a cultural perspective, by building awareness of the importance of local creative classes instead of focusing on importing those classes.     

Retail Mergers and Food Prices: Evidence from France

This paper analyzes the impact of a merger in the French supermarket industry on food prices. Using consumer panel data, we compare the changes in prices for merging and rival firms in affected and comparison markets. We use a novel definition of affected markets when some firms have a local pricing strategy and others a more centralized pricing strategy. We find that prices increase significantly following the merger, and that the merging firms lose market shares. For the rivals, the price increases are larger in local markets, in which concentration increased and differentiation changed after the merger.     

Substitution between leisure activities: a quasi-natural experiment using sports viewing and cinema attendance

The allocation of time between leisure activities and work has been extensively analysed in academic literature. However, leisure time is limited and there may not be sufficient time to enjoy all the leisure activities desired. Hence, this article considers the allocation of time between substitute leisure activities. International football tournaments provide an opportunity to consider consumers’ preferences for watching football and films in a quasi-natural experimental setting. A trade-off between these leisure activities is identified using a difference-in-difference methodology. Using an original, four-country data set, a large and robust negative effect of mega sports events on cinema admissions is identified.     

Masculinising domesticity: an investigation of men’s domestic foodwork

Abstract

This study examines how men configure their gendered identity in relation to a traditionally feminised domain. Hegemonic masculinity is said to structure men’s dominance over women. We use the lens of hegemonic masculinity along with social fields of cultural production to understand new allocations of status capital in relation to gendered identity work. Sweden, a country permeated by an ideology of egalitarianism and having a history of high economic and symbolic incentives for the domestic field, has seemingly legitimised the domestic consumption field in the search for higher status. By exploring the transforming meanings of masculinity when men enter a traditionally feminine consumption domain in this particular cultural context, we identify how feminised masculinities are shaped into hegemonic masculinity. This in turn suggests that the currently most honoured way of being a man includes forms of masculinities that incorporate egalitarian relationships between men and women.     

HEDGING STRATEGIES AND MINIMAL VARIANCE PORTFOLIOS FOR EUROPEAN AND EXOTIC OPTIONS IN A LÉVY MARKET

This paper presents hedging strategies for European and exotic options in a Lévy market. By applying Taylor’s theorem, dynamic hedging portfolios are constructed under different market assumptions, such as the existence of power jump assets or moment swaps. In the case of European options or baskets of European options, static hedging is implemented. It is shown that perfect hedging can be achieved. Delta and gamma hedging strategies are extended to higher moment hedging by investing in other traded derivatives depending on the same underlying asset. This development is of practical importance as such other derivatives might be readily available. Moment swaps or power jump assets are not typically liquidly traded. It is shown how minimal variance portfolios can be used to hedge the higher order terms in a Taylor expansion of the pricing function, investing only in a risk‐free bank account, the underlying asset, and potentially variance swaps. The numerical algorithms and performance of the hedging strategies are presented, showing the practical utility of the derived results.     

Learning by replicator and best-response: the importance of being indifferent

This paper compares two learning processes, namely those generated by replicator and best-response dynamics, from the point of view of the asymptotics of play. We base our study on the intersection of the basins of attraction of locally stable pure Nash equilibria for replicator and best-response dynamics. Local stability implies that the basin of attraction has positive measure but there are examples where the intersection of the basin of attraction for replicator and best-response dynamics is arbitrarily small. We provide conditions, involving the existence of an unstable interior Nash equilibrium, for the basins of attraction of any locally stable pure Nash equilibrium under replicator and best-response dynamics to intersect in a set of positive measure. Hence, for any choice of initial conditions in sets of positive measure, if a pure Nash equilibrium is locally stable, the outcome of learning under either procedure coincides. We provide examples illustrating the above, including some for which the basins of attraction exactly coincide for both learning dynamics. We explore the role that indifference sets play in the coincidence of the basins of attraction of the stable Nash equilibria.     

Contextualising capability development: configurations of knowledge governance mechanisms in project-based organizations

Given the project-based organization’s (PBO) strong focus on autonomy and temporary decentralisation, it faces unique challenges with regard to long-term organisational learning and capability development. To address how PBOs cope with these challenges, we address the role of knowledge governance (KG) mechanisms to foster capability development. The present paper reports on a multiple case study comprising 23 PBOs and demonstrates the importance of ‘configurations of KG mechanisms’ for facilitating learning and capability development. This paper develops four distinct configurations (balanced, formalistic, interactive, and fragile) that promote three principal organisational-level learning processes: shifting, leveraging and adapting. This research underscores the close relationship between knowledge governance mechanisms and capability development and the importance of designing the appropriate configuration of KG mechanisms to foster capability development.     

An empirical investigation of the welfare effects of banning wholesale price discrimination

Economic theory does not provide sharp predictions on the welfare effects of banning wholesale price discrimination: if downstream cost differences exist, then discrimination shifts production inefficiently, toward high‐cost retailers, so a ban increases welfare; if differences in price elasticity of demand across retailers exist, discrimination may increase welfare if quantity sold increases, so a ban reduces welfare. Using retail prices and quantities of coffee brands sold by German retailers, I estimate a model of demand and supply and separate cost and demand differences. Simulating a ban on wholesale price discrimination has positive welfare effects in this market, and less if downstream cost differences shrink, or with less competition.     

Why sad people like shoes better: The influence of mood on the evaluative conditioning of consumer attitudes

An experimental study investigated the influence of mood on the acquisition of affective consumer attitudes. Within an evaluative conditioning paradigm, participants in happy or sad mood were presented with evaluatively neutral products paired with affectively liked or disliked faces. Subsequent likability ratings revealed that the mere co‐occurrence of a product with the valenced face influenced the evaluation of the previously neutral targets. However, this effect of affective learning was significantly stronger in the sad‐mood condition. A subsequent awareness test indicated that contingency awareness plays a role in the acquisition of consumer attitudes. The implications for consumer research and attitude formation processes are discussed. © 2004 Wiley Periodicals, Inc.
