PurposeAlternative food networks (AFNs) have recently emerged in the food landscape as new ways of food production, distribution and consumption which are alternatives to the traditional food system. Drawing on the tragedy of the commons, this paper aims to test the role played by social capital and transparency in reducing customer's lethargy and thus enhancing AFN performance in terms of frequency and quantity of purchases made by customers.Design/methodology/approachAn ordered probit model was used to analyse data from a strong database of 2,115 Italian AFN customers. Given the novelty of the topic, the quantitative survey was anticipated by a preliminary qualitative study based on in-depth interviews, focus groups and participant observation.FindingsCustomers play an active role in AFN communities, co-creating value together with the other actors of the network. The two independent variables tested in this model, social capital and transparency, positively and significantly affect customers' quantity and frequency of purchases within AFNs, reducing the occurrence of the tragedy of commons.Originality/valueTo the authors' knowledge, this study represents one of the first attempts to measure, through a quantitative method, the effect of performance drivers (i.e. social capital and transparency) on AFN performance. Theoretical, managerial and policy implications will be thoroughly presented and discussed along the paper.
Spatial contagion between two financial markets X and Y appears when there is more dependence between X and Y when they are doing badly than when they exhibit typical performance. In this paper, we introduce an index to measure the contagion effects. This tool is based on the use of suitable copulas associated with the markets and on the calculation of the related conditional Spearman's correlation coefficients. As an empirical application, the proposed index is used to create a clustering of European stock market indices to assess their behavior in the recent years. The whole procedure is expected to be useful for portfolio diversification in crisis periods.
The resilience of communities is given by the ideal convolution of the resilience of all their single parts. Strategic buildings require high levels of performance during and after a seismic sequence. Consequently, the seismic retrofitting of old strategic buildings is a central issue in prevention and mitigation strategies. The core of the study is a resilience approach to the seismic retrofitting of existing strategic buildings. Different performance levels are considered and four different retrofitting techniques are compared according to their fragility, and their post-earthquake cost and time recovery analyses. Lastly, the retrofitting techniques are compared based on the considered resilience index, which in turn is related to the estimated reduction of the seismic losses owing to the different retrofitting techniques, but especially to the effectiveness of the intervention based on the relevant cost and recovery times. In other words, these aspects take into account the key role of a building’s characteristics, and its public and strategic role during and after an earthquake. The intervention is selected not only (as is currently done) to reduce its construction times and costs, but to limit the service interruption after earthquakes. The results of this study could be operatively used as support tools in the seismic retrofitting of strategic buildings, either individually or on a large territorial scale.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
