Time to Include Blue Carbon from Seaweed in Voluntary Carbon Removal Certification

The EU has proposed a voluntary framework for certification of carbon removals which remains vague on blue carbon and in particular, carbon removal through use of seaweeds. Seaweed is considered an emerging blue carbon option. Various studies have confirmed the potential of seaweed to contribute to long-term carbon removal, storing it away from the atmosphere for 100 years and more. Certification of seaweed carbon sequestration is promoted, even in other EU communications. This article reviews early experiences with certification of carbon and nutrient removal by aquaculture using the QU.A.L.ITY criteria proposed by the EU. Examples reviewed include the Seaweed Company, Venice Bay, Yokohama Bayside marine, and Chesapeake Bay in the USA. After reviewing these examples, we call on the European Commission to move forward towards certification of blue carbon. If the EU is to lead global climate mitigation efforts, including carbon removal, it should take seaweed blue carbon seriously and include it in its voluntary framework. To enhance the awareness of the relevance and the acceptance of the carbon credits from seaweed, a methodology has to be developed that, building on experiences gained, deals with inherent uncertainties.     

Private Equity Involvement and Earnings Quality

Abstract:  This paper examines the relation between private equity (PE) investors' involvement and their portfolio firms' earnings quality. We operationalize earnings quality through comparative analyses of conditional loss recognition timeliness. For a sample of unlisted Belgian firms, we find that PE involvement increases a firm's willingness to recognize losses more timely as compared to industry, size and life-cycle matched non-PE backed firms. Further, we document more powerful earnings quality effects for firms backed by independent and captive PE-investors as compared to firms backed by government-related PE-investors. Finally, we find no systematic variation in earnings quality across different levels of PE ownership. Our results are robust to the inclusion of various controls and remain unaffected when we consider the endogeneity of PE investments and compare pre- and post PE investment years. The current results provide novel evidence towards the understanding of PE investors' governance implications for portfolio firms' earnings quality.     

Use and knowledge of food labels of shoppers in a city with a high proportion of heart disease

This study aimed to assess consumers’ use and understanding of food labelling and the improvements that they would like. Systematically selected supermarket shoppers were interviewed using a questionnaire. Data showed that the use of food labels was low. Among those who read food labels, at least occasionally, use‐by‐date was the most reported information looked at. Understanding of the content of five nutrients on a standard food label provided was poor. Although a high proportion of participants claimed to have no problem with the current format, those who had problems wanted food labels that were ‘bigger’, ‘highlighted’ or written in ‘plain English’. These results suggest that before improved food labels can have an impact on consumers’ food choice, strategies to encourage shoppers to read them are needed.     

Managing Interactions between Technological and Stylistic Innovation in the Media Industries

The processes of technological innovation have been widely researched, but their interactions with another type of innovation that is particularly important in sectors like the fashion and the media content industries have been neglected: stylistic innovation. This paper puts forward the idea that a better understanding of such interactions between content and technology in the media industries might help explaining differences in the receptiveness of firms towards new technological opportunities. The nature of the interactions, so it is argued in this paper, depends on three groups of key factors at the level of the product, the organization and the industry: among them, first, the locations of the different types of innovation in the media product's components; second, organizational factors like the identity and the reputation of a firm with respect to the above types of innovation; and third, the industry-specific characteristics of the certification environment in which the firms operate. Awards are discussed as specific instantiations of micro certification environments indicating quality with respect to stylistic and/or technological product features. To round off the theoretical part, a definition of stylistic innovation is developed with reference to the key concepts discussed in this paper. Within the media sector the literary publishing industry has been chosen to provide the subject of the empirical part. Two cases related to the introduction of eBook technology are presented: one is a study of the first digital literary publisher in Europe and the other is a case study of the first international eBook award, which mixes technological and stylistic criteria. Theory and cases lead to a number of hypotheses offered as potential departure points for future research into the interactions between innovation in style and technology.     

Nash equilibrium in games with incomplete preferences

Summary. This paper investigates Nash equilibrium under the possibility that preferences may be incomplete. I characterize the Nash-equilibrium-set of such a game as the union of the Nash-equilibrium-sets of certain derived games with complete preferences. These games with complete preferences can be derived from the original game by a simple linear procedure, provided that preferences admit a concave vector-representation. These theorems extend some results on finite games by Shapley and Aumann. The applicability of the theoretical results is illustrated with examples from oligopolistic theory, where firms are modelled to aim at maximizing both profits and sales (and thus have multiple objectives). Mixed strategy and trembling hand perfect equilibria are also discussed.Received: 22 September 2003, Revised: 24 June 2004, JEL Classification Numbers: D11, C72, D43.I would like to thank Jean-Pierre Benôit, Juan Dubra, Alejandrio Jofre, Debraj Ray, Kim-Sau Chung and the seminar participants at NYU and at the Universidad de Chile for their comments.

APPROACHES TO PRICE FORMATION IN FINANCIALIZED COMMODITY MARKETS

A recent debate about the financialization of commodity markets has stimulated the development of new approaches to price formation which incorporate index traders as a new trader category. I survey these new approaches by retracing their emergence to traditional price formation models and show that they arise from a synthesis between commodity arbitrage pricing and behavioural pricing theories in the tradition of Keynesian inspired hedging pressure models. Based on these insights, I derive testable hypotheses and provide guidance for a growing literature that seeks to empirically evaluate the effects of index traders on price discovery in commodity futures markets.     

‘And now I’m free’: Women’s empowerment and emancipation through entrepreneurship in Saudi Arabia and Sweden

Critical perspectives have called for the study of women’s entrepreneurship as a route to social change. This ‘social turn’ claims women are empowered and/or emancipated through entrepreneurship with limited problematisation of how these interchangeably used concepts operate. Using an institutional perspective in combination with a narrative approach, we investigate women entrepreneurs’ life stories on their ‘road to freedom’ where entrepreneurial activity enables them to ‘break free’ from particular gendered constraints. Through juxtaposing women’s narratives in the contexts of Saudi Arabia and Sweden, the relationship between empowerment and emancipation is disentangled and (re)conceptualised. The findings distinguish between empowerment narrated as individual practices to achieve freedom for the self within institutional structures and emancipation as narrated as a wish to challenge and change structures of power and reach collative freedom. The yearning for collective emancipation propels women’s stories of entrepreneurship by raising expectations for entrepreneurship as a vehicle for institutional change. Such stories may fascinate and inspire others to engage in entrepreneurial endeavours to become empowered, but whether they reach emancipation remains an empirical question to be answered. The performative dimension of entrepreneurial narratives is, however, their ability to turn emancipation into an (un)reachable object of desire, with a quest for even more individual empowerment and entrepreneurial activity, at the same time excluding other forms of human conduct as conducive for change.     

The Impact of Managers’ Participation in Costing System Design on Their Perceived Contributions to Process Improvement

The aim of this paper is to investigate the impact of managers’ participation in costing system design on their perceived contributions to process improvement. Drawing on the literature on business process management, participative decision-making and self-determination theory, we propose that participation in costing system design fosters managers’ perceived contributions to process improvement through their autonomous motivation for cost management and their perceived usefulness of cost information. Questionnaire data obtained from 170 Belgian managers were used to test the proposed model. The results suggest that participation in costing system design increases managers’ autonomous motivation for cost management and enhances their perceived usefulness of cost information. Managers’ perceived usefulness of cost information is, in turn, positively associated with their perceived contributions to process improvement. The effect of managers’ autonomous motivation for cost management on their perceived contributions to process improvement is, however, not significant. Taken together, our findings imply that contributions to process improvement mainly emerge through informational mechanisms rather than motivational mechanisms triggered by the participation process.     

Pesticide residues and trade,the apple of discord?

In this paper we study the impact of the regulations on Maximum Residue Levels (MRLs) of pesticides on the trade of apples and pears and related processed products with the aim of understanding how their similarity (or dissimilarity) affect trade. Most studies investigate the impact of sanitary regulations introducing directly in the analysis the MRL put in force in the importing country. They introduce in the analysis the level of the regulation in the importing country without taking into account the rule in force in the exporting country. Rather than focusing on a particular pesticide we take into account the entire list of substances set out by the various regulations. We then build a similarity index and introduce it into a gravity equation to assess the impact of the differences in MRL of pesticides on trade. Results suggest that the differences between regulations matter and may, in some case, hinder trade.
