Regulatory reform of the UK gas market: The sase of the storage auction

The UK gas industry has undergone major changes since it was privatised in 1986 as a fully integrated monopoly. The most significant of these has occurred not as a result of the privatisation legislation but by the intervention of the ordinary competition authorities in support of an active industry regulator. While price capping continues to be used as the primary instrument for welfare protection against the still substantial monopolistic powers of the incumbent, new competition (which has been positively encouraged) has had the greater impact on prices and choice. Recently, however, the regulator has encouraged the use of auctions for the sale of storage capacity. This paper considers the merits of auctions and makes a tentative evaluation of their effectiveness. Further use of auctions is recommended but reserve prices are considered inappropriate where monopoly power still remains.     

Children aged 9-14 living in disadvantaged areas in England: Opportunities and barriers for cycling

The aim of this paper is to take a holistic perspective to explore levels of cycling and opportunities and barriers to increase children’s safer cycling in disadvantaged areas in England. The study was one part of a larger study which explored the factors underlying the high level of road traffic casualties especially among children in the most disadvantaged areas of England and to explore how this impacts on mobility and quality of life. The methods involved a cross sectional survey comprising school based questionnaire surveys with children aged 9-14 and focus groups with parents who had children within this age range. The surveys were conducted in 2007 and the focus groups during 2008. 4286 children completed the survey and eight focus groups were held. Bike ownership (77%) was high, use in previous week moderate (39%) but only 2% cycled to school. Ownership was significantly lower in minority ethnic groups. Despite young children’s strong preference to travel by cycle (30%) than walk or go by car, most parents felt it was too hazardous. It is unlikely that these findings would be any different from the rest of England, however the combination of environmental and social factors may elevate the risks for young cyclists in these areas. This paper concludes that a number of barriers exist to increasing levels of cycling among children living in disadvantaged areas particularly amongst ethnic groups. These barriers could be addressed by environmental modifications to reduce speeds and by reducing the levels of antisocial driving and riding in residential areas and around destinations where children travel, by providing cycle training to improve children’s skills and parent’s confidence, and by providing secure storage facilities for bikes. Until these barriers are addressed it is unlikely that cycling will increase despite the strong preferences children have to travel by bike. Such preferences to cycle provide an opportunity for local authorities to act on.     

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.     

Portfolio flows and the US dollar–yen exchange rate

This paper investigates the effects of portfolio flows on the US dollar–Japanese yen exchange rate changes over the period 1988:01–2011:04. Using a time-varying transition probability Markov-switching framework, the results suggest that the impact of portfolio flows on the dollar–yen exchange rate changes is state-dependent. In particular, the results show that portfolio inflows from Japan toward the US, more than monetary variables, strengthen the probability of remaining in the dollar–yen appreciation (low volatility) state. Therefore, credit controls on the flows can be used as a policy tool to pursue economic and financial stability.     

Rural-urban gradient analysis of ecosystem services supply and demand dynamics

Urban regions are important places of ecosystem service demands and, at the same time, are the primary source of global environmental impacts. Although there is broad agreement on the importance of incorporating the concept of ecosystem services into policy strategies and decision-making, the lack of a standardized approach to quantifying ecosystem services at the landscape scale has hindered progress in this direction. Moreover, tradeoffs between ecosystem services and the supply/demand ratio of ecosystem services in urban landscapes have rarely been investigated. In our paper, we present a method to quantify and map the supply and demand of three essential provisioning services - energy, food, and water - along the rural-urban gradient of the eastern German region Leipzig-Halle. This urban region has experienced significant socio-economic dynamics and land use changes since the German reunification in 1990. The results show that both the demand and the supply of ecosystem services changed considerably during the time span under consideration (1990-2007). We identified an increasing supply/demand ratio of food and water but a decreasing supply/demand ratio of energy. In addition, the pattern of ecosystem demands shows a levelling of rural-urban gradients, reflecting profound modifications of traditional rural-urban relationships. The changes of ecosystem service supply gradients are determined more by land use intensity, such as the intensification of agricultural production, than by land cover changes such as urban sprawl. The comparison of supply/demand ratios and rural-urban patterns of ecosystem services can help decision-makers in landscape management in striving for a sustainable balance between resource supply and demand.     

Competition and Regulation in Franchise Bidding

In this work we show that the separation property identified in the franchise bidding literature depends strictly on the hypothesis of coincidence of the regulator's beliefs with those of the competing firms. Nevertheless, in many contexts it is more truthful to hypothesize that the regulator's information is vaguer than that of the producers, so we introduce the possibility that the regulator is dealing with a double informational asymmetry as compared to the firms. In this case, the separation property is no longer valid, and the optimal tariff becomes a decreasing function of the degree of competition exercised during the auction.     

Shaping buyer–supplier relationships in manufacturing contexts: Design and test of a contingency model

Although the idea that buyer–supplier partnerships can yield considerable benefits to firms is largely diffused among researchers and practitioners, the approach adopted in this paper is that no “one best way” exists in buyer–supplier relationships, but rather a “best way” for each specific exchange context. Hence, this paper proposes a contingency model for shaping and managing buyer–supplier relationships in manufacturing contexts. In order to test the model, an empirical study was performed on a sample of 45 buyer–supplier relationships within the Italian white goods industry. A three-dimensional performance indicator was computed to compare supplier performance achieved within relations matching the model's suggestions with those set differently. The results strongly suggest that suppliers involved in relationships set accordingly to the contingency model are likely to enjoy superior performance.     

BUILDING THE MANAGERIAL CAPITAL OF AGRICULTURAL COOPERATIVES IN AFRICA

Agricultural cooperatives in Africa tend to be community‐based organizations defined by principles of inclusion, voluntarism, democracy, equity, autonomy, mutuality and solidarity. This means that they generally operate in accordance with the principles endorsed by the International Cooperative Alliance (ICA). However, only a few of these organizations are successful in commercializing the agricultural produce of their members. In this study, we argue that growth‐problems leading to commercial failure and organizational degeneration in these cooperatives can be attributed to a lack of managerial capital. Drawing on the literature and evidence from the field we set out key management solutions for counterbalancing cooperative principles in the context of rural Africa. These solutions were taught to the leaders and managers of 362 cooperatives at four training events held in Madagascar, Malawi and twice in Uganda. Using a production function for cognitive achievement and key informant interviews, we find that our training contributed to the adoption of the proposed solutions by some of the cooperatives. Using the Ugandan sub‐ sample, we estimate an OLS regression and a PSM model to show that the training translated into higher revenues per member generated through collective commercialization.     

Responsible Leadership: Pathways to the Future

After defining the essential elements of Aristotelian citizenship, the article proposes to apply these criteria in its search for the equivalent of a citizen within the corporate polis. It argues that shareholding managers are the best positioned among a firm’s constituents or stakeholders in fulfilling the role of corporate citizens. Greater participation by management not only in the control but also in the ownership of firms brings about benefits for the firm as a whole and for the managers themselves, as organizational citizenship behavior literature, among others, suggests.
