There is no single 'best way' of policy development. Bottom-up approaches to policy design and a broad debate among stakeholders facilitate policy learning and innovation. A novel approach of a bottom-up policy design process involving stakeholders is introduced. First results obtained by this methodology are presented. The outcomes of a large international effort for a development of policies for organic food and farming in Mai 2004 in Europe are analyzed: the synthesized results from 11 European countries (AT, CH, CZ, DE, DK, EE, GB, HU, IT, PL, SI) on the current situation of policies related to the organic food market in Europe are highlighted and policy recommendations for the development of the organic food and farming sector formulated....

Delayed perfect monitoring in an infinitely repeated discounted game is modelled by allocating the players to a connected and undirected network. Players observe their immediate neighbors’ behavior only, but communicate over time the repeated game’s history truthfully throughout the network. The Folk Theorem extends to this setup, although for a range of discount factors strictly below 1, the set of sequential equilibria and the corresponding payoff set may be reduced. A general class of games is analyzed without imposing restrictions on the dimensionality of the payoff space. Due to this and the bilateral communication structure, truthful communication arises endogenously only under additional conditions. The model also produces a network result; namely,...

ATITUDES DE COORDENAÇÃO DE PRODUTORES RURAIS NA CADEIA DA CARNE BOVINA: O CASO DO CITE 120

Malafaia, Guilherme Cunha; Maciel, Alessandra Costenaro; Camargo, Maria Emilia.

The changes in the worldwide competitive scenario have posed difficulties to the survival of companies, forcing them to establish necessary cooperative relations for maintenance and survival in the markets. However, the lack of coordination and cooperation is considered a classic problem in the beef chain. Taking these assumptions into account, the purpose of the present article is to verify how the organizational network CITE 120, established by a group of beef producers in the state of Rio Grande do Sul (RS), has addressed the environmental demands in the meat production sector and how the systemic relationships for the strengthening of the network’s interests are being promoted and organized. For the purpose of this research in-depth interviews were...

Network performance - What influences it?

Lefebvre, Virginie M.; Molnar, Adrienn; Gellynck, Xavier.

The aim of this paper is to examine the literature addressing network performance and the factors influencing it. Design – 29 papers published in 18 different journals were systematically reviewed through a multidimensional classification framework based on the strategy-structure-performance paradigm of strategic management. Findings – Based on the outputs of the literature review, a conceptual framework describing network performance is proposed. Following this framework, it is suggested that network performance is the result of the combination of network strategy, network structure and external environmental factors, and not solely the result of network structure which is characterized by five structural elements i.e. network configuration, network...

Medicamento, Umberto; De Gennaro, Bernardo.

In recent years, due to the growing supply of organic production, the economic performances and the competitive advantages of the farms, have become more dependent on network organisations in the supply chains. This evolution equires methodological approaches able to capture all the variables involved in the generating value processes. The network dimension of the supply chain has become a key element, and enables us to understand better the competitive performances of firms. The relationships of firms, among intangible assets, are recently considered one of the main sources of profit. So the relational capital forms the essence of the value of the firm and it is advantages on the whole coming out by occupying a specific position (role) in the network of...

This paper extends the theory of endogenous coalition formation, with complete information and transferable utility, to the overlapping case. We propose a cover function bargaining game which allows the formation of overlapping coalitions at equilibrium. We show the existence of subgame perfect equilibrium and provide an algorithm to compute this equilibrium in the symmetric case. As an application, we establish an interesting link with the formation of networks.

Imperfect private monitoring in an infinitely repeated discounted Prisoner’s Dilemma played on a communication network is studied. Players observe their direct neighbors’ behavior only, but communicate strategically the repeated game’s history throughout the network. The delay in receiving this information requires the players to be more patient to sustain the same level of cooperation as in a complete network, although a Folk Theorem obtains when the players are patient enough. All equilibria under exogenously imposed truth-telling extend to strategic communication, and additional ones arise due to richer communication. There are equilibria in which a player lies. The flow of information is related with network centrality measures.

REDES DE COLABORACIÓN, ESTRATEGIA EMPRESARIAL EN LA INSERCIÓN A CADENAS DE VALOR

Arras Vota, Ana Maria; Fierro Murga, Luz Ernestina; Jaquez Balderrama, Jose Luis; Lopez Diaz, Julio Cesar.

This piece of work presents three cases: Caprica, Productores de Chihuahua and Los Porcicultores, all of which have united their efforts and created enterprises as a strategy through which the participants –small producers- generate networks to associate. This allows them the opportunity to insert in value chains and acquire better conditions for their goods, and at the same time they can give them an added value, and by doing this, they find themselves in a different state of integration and insertion in the value chain, which gives them the opportunity to face the challenges of actual life. This paper visualizes the enterprise from the systemic perspective, and as a collectivity of capabilities. Also, it presents the concept of network - individual or...

Whether particular countries, regions within countries, and particular societies gain or lose in the process of globalization depends on where they are in the process of agricultural transformation and to what extent they can adjust? The Hungarian pork chain faces considerable disadvantages in several aspects as opposed to competing countries. In countries with developed meat chain a powerful concentration could be observed, whereas in Hungary, although disintegration has not increased, decentralization still prevails. In our research the operation of the co-operative was modelled as a generalized network problem in 2008. The model allows the quantification of the number of pigs from given farms to slaughterhouses, the maximum revenue from sales, the...

Zusammenfassung: Der Wettbewerbsdruck in der europäischen Milchviehhaltung nimmt durch die fortschreitende Liberalisierung des EUMilchmarktes zu. Bestehende agrarökonomische Forschungsmethoden sind nur begrenzt dazu in der Lage, belastbare Abschätzungen der regionalen Wettbewerbsfähigkeit und künftiger Standortverlagerungen innerhalb Europas zu treffen. Ziel der vorliegenden Arbeit ist es, in einem explorativen Verfahren einen Befragungsansatz zu schaffen, mit dem ein ergänzender Beitrag für eine solche Vorhersage geleistet werden kann. Der Befragungsansatz wurde innerhalb der Netzwerke „European Dairy Farmers“ und „agri benchmark“ entwickelt und in europäischen Milchviehbetrieben eingesetzt. Eine nicht repräsentative Auswahl dieser Betriebe bildet die...

Godquin, Marie; Quisumbing, Agnes R..

This paper explores the determinants of group membership and social networks of rural households using a unique longitudinal data set from the rural Philippines. We investigate two types of social capital: membership in groups (production, credit, burial, religious and civic groups), or “formal” social capital, and size of trust-based networks or “informal” social capital. Because men and women may have different propensities to invest in social capital, we analyze the determinants of group membership both at the household level and for men and women separately. We also disaggregate the analysis by type of group. The paper examines the determinants of the density of social capital, proxied by the number of groups and the number of network members. Finally,...

Small World Networks with Segregation Patterns and Brokers

Balogh, Peter; Ertsey, Imre; Fenyves, Veronika; Nagy, Lajos.

In many ways, the Hungarian pork chain faces considerable disadvantages when compared to the situation in competing countries. In countries endowed with a modern meat chain, heavy concentration is the rule, but in Hungary decentralization still prevails, although thankfully the chain is not disintegrating even further. In our research we used the operation of co-operatives as a model in terms of a generalized network problem. The model allows the quantification of the number of pigs from given farms to slaughterhouses, the maximum sales revenue, the delivery threshold prices, and an analysis of the impact co-operative members exert on sales revenues.

Gallo, Edoardo.

Many social networks have the following properties: (i) a short average distance between any two individuals; (ii) a high clustering coefficient; (iii) segregation patterns; the presence of (iv) brokers and (v) hubs. (i) and (ii) define a small world network. This paper develops a strategic network formation model where agents have heterogeneous knowledge of the network: cognizant agents know the whole network, while ignorant ones are less knowledgeable. For a broad range of parameters, all pairwise Nash (PN) networks have properties (i)-(iv). There are some PN networks with one hub. Cognizant agents have higher betweenness centrality: they are the brokers who connect different parts of the network. Ignorant agents cause the emergence of segregation...

In this paper we study the effects of institutional constraints on stability, efficiency and network formation. More precisely, an exogenous "societal cover" consisting of a collection of possibly overlapping subsets that covers the whole set of players and such that no set in this collection is contained in another specifies the social organization in different groups or "societies". It is assumed that a player may initiate links only with players that belong to at least one society that s/he also belongs to, thus restricting the feasible strategies and networks. In this way only the players in the possibly empty "societal core", i.e., those that belong to all societies, may initiate links with all individuals. In this setting the part of the current...
