Sustainability and the value of the ‘regulating’ services: Wetlands and water quality in Lake Victoria

The regulating services provided by ecosystems are amongst the most important for the sustainability of resource use, and yet they are also amongst the least understood. This paper considers one set of regulating mechanisms - the buffering functions of wetlands - and considers the information needed to identify both the value of the services offered by wetlands, and their substitutes. Using data from a catchment discharging water and nutrients to the Kenyan segment of Lake Victoria, the Yala catchment, the paper models the interactions between agriculture and fisheries as mediated by wetlands at the lake margin. More particularly, it estimates the value of the forgone nutrient retention function involved in the conversion of the wetland to agriculture, and the scope for providing the same services through land use change elsewhere in the catchment. The total cost of the payments that would compensate farmers for on-farm nutrient buffering services is 3.86 M US$ year^− 1, or 35% of the total gains from wetland conversion to crop production. This finding contributes to an understanding of both the value of regulating services and how they might most effectively be delivered in alternative ways.     

Sustainability drivers in food retail

Sustainability has become a relevant issue for retailers. We develop an integrated model with three drivers of retailer's investments in sustainability. First, the more their processes, human resources and customer driven capabilities are developed, the more investments in sustainability tend to occur. Second, retailers leverage their relationships with suppliers to invest in sustainability. Third, competition and economic instability may also lead to long run investments in social and environmental. We tested three hypotheses by surveying 101 retailers operating supermarkets, hypermarkets and neighborhood stores that focus mainly on food with a limited offering of general merchandise and apparel. Our results show the importance of customer driven capabilities for investments in sustainability. Communication with the supplier also has an impact on investments, while the process and policies of the supplier relationship do not. Retailers invest in sustainability to coordinate this relationship. Our study sheds light on the drivers for sustainability and offers an understanding of how a retailer may invest further in sustainability.     

Emergent complex systems

Complex systems are becoming the focus of important innovative research and application in many areas, reflecting the progressive displacement of classical physics and the emergence of a new and creative role for mathematics. This article makes a distinction between ordinary and emergent complexity and argues that a full analysis requires dialectical thinking. In so doing the authors aim to provide a philosophical foundation for post-normal science. The exploratory analysis developed here is complementary to those conducted with a more formal, mathematical approach, and begins to articulate what lies on the other side of that somewhat indistinct divide, the conceptual space called emergent complexity.     

Organizational creativity as a crucial resource for building international business competence

We aim to elucidate the roles that organizational creativity plays in the development of firms’ international business competence (IBC). We conducted an investigation grounded in the resource-based view of how this intangible resource supports the development of capabilities and competences. We surveyed 77 Brazilian audiovisual SMEs and analyzed our data using OLS regression analysis. The results partially support the hypothesis that organizational creativity is a building block for IBC but show that its effect is mostly exerted through the mediation of some of the dimensions of innovative and entrepreneurial capabilities. This study has implications both for organizations and public policies, contributing to the debate on how firms stimulate innovation and entrepreneurship and how public agents can leverage SMEs’ internationalization process.     

Do European capital flows comove?

We study the cross-section correlations of net, total, and disaggregated capital flows for the major source and recipient European Union countries. We seek evidence of changes in these correlations since the introduction of the euro to understand whether the European Union can be considered a unique entity with regard to its international capital flows. We make use of Ng’s (2006) “uniform spacing” methodology to rank cross-section correlations and to shed light on potential common factors driving international capital flows. We find that a common factor structure is suitable for equity flows disaggregated by sign but not for net and total flows. We only find mixed evidence that correlations between types of flows have changed since the introduction of the euro.     

Organizational Goals,Outcomes, and the Assessment of Performance: Reconceptualizing Success in Management Studies

We revisit the study of organizational goals, outcomes, and assessment of performance that together define the process leading to ‘success’. We begin by conducting a systematic review of existing research which allows us to develop an integrative framework discussing this large body of work. We then describe contemporary research examples in light of our proposed framework. We close by proposing four new areas to continue to advance the field: reconceptualizing performance (and success) as achievement of goals; diversity of goal systems in research designs, and their relationship with the purpose of an organization; multilevel and temporal dynamics; and governance of goal setting. Overall, our efforts inform future research on organizational success in the context of our new societal challenges and accomplish the intriguing task of re-defining success in management studies.     

Fixed and Random Effects in Classical and Bayesian Regression*

This paper proposes a common and tractable framework for analyzing fixed and random effects models, in particular constant‐slope variable‐intercept designs. It is shown that, regardless of whether effects (i) are treated as parameters or as an error term, (ii) are estimated in different stages of a hierarchical model, or whether (iii) correlation between effects and regressors is allowed, when the same prior information on idiosyncratic parameters is introduced into all estimation methods, the resulting common slope estimator is also the same across methods. These results are illustrated using the Grünfeld investment data with different prior distributions. Random effects estimates are shown to be more efficient than fixed effects estimates. This efficiency gain, however, comes at the cost of neglecting information obtained in the computation of the prior unknown variance of idiosyncratic parameters.     

ICT diffusion in public administrations and business dynamics: Evidence from Italian municipalities

Public administrations have been adopting information and communication technologies (ICT) to transform their internal organization and provide better public services to citizens and firms. However, the external benefits, despite being deemed relevant, have been empirically overlooked. We first explore the relation between ICT diffusion in public administrations and business demography at the municipal level by studying the Italian context. Our results show that ICT diffusion in the PA contributes to significantly reducing the death rate of firms and boosting their turnover rate. The adoption of ICT in the PA also exerts a positive impact on the firm birth rate, although it is not statistically significant. These results shed light on the importance of promoting e-government and framing coherent digital agendas as public instruments for supporting entrepreneurship and regional economic development.
