Proximity, knowledge integration and innovation: an agenda for agent-based studies

In this paper, we develop a theoretical model able to capture some of the main features that govern knowledge sharing and innovation. We pursue our target developing an agent-based model in which the social network of interactions is specified as a knowledge resource, and knowledge integration is seen as the process by which the resource can be applied to innovation. The results of the simulation exercises show that the initial architecture of acquaintance networks is a crucial factor for innovation. Innovating has proven to be more than simply equating endowments of initial skills with firm performance. In fact, the performance of the system showed high sensitivity to the arrangement of the firm’s initial location in the social network. Moreover, the way in which acquaintance networks were mobilized emerged as a key determinant of innovation patterns. The model presented here is a relatively theoretical, stylized model and we employ it to draw some general, albeit preliminary conclusions, while illustrating some of the theory relevant to the issues discussed. It is argued that the model might serve the purpose of setting an agenda for further research along this line of investigation—that is, knowledge integration patterns and firms partnerships formation.     

Knowledge Diffusion and Networking in the Organic Production Sector: A Case Study

Knowledge Diffusion and Networking in the Organic Production Sector: A Case Study
Recent uncertainty throughout the food system has put pressure on European farmers, now facing economic globalisation, changing consumer preferences, and a new legal and regulatory framework. Under these new circumstances, policy-makers must identify new strategies for developing food production systems in ways that benefit the whole of society, whilst minimising negative effects upon the environment. In this regard, the organic food sector, characterised by an ever more complex legislative framework and policy environment, presents an opportunity and a challenge for policy-makers as well as for farms and firms. This article reports findings from a case study of knowledge diffusion in the organic sector in the province of Foggia, a developmentally backward area in Southern Italy. Our study shows that despite a cohesive'network of interactions' among organic producers, exchanges of knowledge are fairly marginal. This communication void is partially filled by local institutions that are shown to be effective in diffusing juridical and technical knowledge but less effective in providing commercial/market information. Further institutional efforts are required to cover these knowledge gaps. The study draws attention to some policy issues that can be shared by groups of organic producers elsewhere with characteristics similar to the Foggian case study, similarities that call for institutions to facilitate the creation, interpretation, and sharing of knowledge.     

Does a ‘financial transaction tax’ drive out information mirages? An experimental analysis

Motivated by the debate over the economic implications of financial transaction taxes, the present study involved a thorough investigation of the impact of such taxes on a financial market of the type described by Camerer and Weigelt (J Bus 64:463–493, 1991), whereby noise traders are unaware of whether privileged information is fluctuating in the market. Two treatment conditions were opposed to a baseline condition in which no tax was levied. The two treatment conditions imposed a transaction tax equal to 0.5% and 1% of each transaction’s market value, respectively. The findings show that: (1) the introduction of a tax did not affect the occurrence of a mirage, (2) the introduction of a tax did not improve market efficiency and (3) the introduction of a tax did not reduce the number of transactions.

     

Knowledge diffusion dynamics and network properties of face-to-face interactions

This paper aims to understand some of the mechanisms which dominate the phenomenon of knowledge diffusion in the process that is called interactive learning. We examine how knowledge spreads in a network in which agents interact by word of mouth. The social network is structured as a network graph consisting of agents (vertices) and connections (edges) and is situated on a wrapped cellular automata grid forming a torus. The target of this simulation is to test whether knowledge diffuses in a homogeneous way or whether it follows some biased path towards convergence or divergence.JEL Classification: D63, O30, R10Corespondence to: Piergiuseppe MoronePiergiuseppe Morone, Richard Taylor: The authors are grateful to Nick von Tunzelmann, Scott Moss, Robin Cowan and Ed Steinmueller for helpful comments in different stages of the work.

Discretionary enforcement and strategic interactions between enforcement agencies and firms: a theoretical and laboratory investigation

This paper presents a game theoretic morphological analysis of the strategic interactions between environmental enforcement authorities and polluting firms. The models explore the role of discretion that such authorities enjoy, either in deciding how to pursue environmental violations (investigative and prosecutorial discretion) or in judging them (judicial discretion). The purpose is to identify both the optimal firms’ behaviour in terms of compliance, and the enforcement authorities’ optimal strategies in terms of enforcement actions to undertake. Consistent with the setting of the game theoretic models, the role of the enforcement agencies in deterring firms from polluting is, then, empirically tested by means of laboratory experiments. Laboratory evidence on compliance behaviour of firms when faced with enforcement conditions predicted by the theoretical models set up is discussed for the different experimental treatments performed. Overall, we suggest that making environmental enforcement less predictable for the firms, and thus creating a degree of uncertainty for the violators, can actually encourage deterrence and, thus, improve compliance. Thus, a partly unpredictable enforcement strategy may generate more compliance than an environmental policy that is known with certainty in advance.     

THE FOCAL POINT IN THE TRAVELLER'S DILEMMA: AN EXPERIMENTAL STUDY

This paper provides an experimental test of the traveller's dilemma. Our investigation aims to address the research hypothesis that introducing a reference point à la Schelling (set equal to the Pareto optimal solution) might drive people away from rationality even when the size of the penalty/reward is high. Experimental findings reported in this paper provide answers to this question showing that the reference point did not encourage coordination around the Pareto optimal choice.
