    The Two Faces of Knowledge Diffusion: the Chilean Case

    This paper analyses the dynamics of return to knowledge where knowledge is acquired through the combination of interactive and individual learning. We suggest that in light of this new definition of knowledge, choosing the optimal level of education is no longer an individual exercise of present and future utility maximisation as suggested by more formal human capital theory (Becker, 1964). In fact, other external (environmental) variables might affect the individual decision of investment. We calculate the effect of individual and interactive learning in determining the wage of Chilean workers aged between 14 and 65.Chile, Inequality, Latin America, Knowledge, Schooling returns

    Eliciting environmental preferences of Ghanaians in the laboratory: An incentive-compatible experiment

    In this paper we aim to look into the attributes of Ghanaians’ willingness-to-pay for green products. This would help us to assess whether Ghanaians show a preference towards environmental goods. The methodology employed to address these issues is an ‘experimentally-adapted’ CV survey which involves laboratory experiment conducted among Ghanaian University students. Notwithstanding the limitations arising from the sample used in our experiment (most notably University students do not represent, economically wise, the entire Ghanaian population), we believe that our investigation provides a first answer to such question as Ghanaians consistently show that they are willing to pay an extra premium for green products.contingent valuation, experiment, incentive-compatible, Ghana, organic products, willingness to pay

    A Laboratory Experiment of Knowledge Diffusion Dynamics

    This paper aims to study, by means of a laboratory experiment and a simulation model, 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 different networks in which agents interact by word of mouth. We define a regular network, a randomly generated network and a small world network structured as graphs consisting of agents (vertices) and connections (edges), situated on a wrapped grid forming a lattice. The target of the paper is to identify the key factors which affect the speed and the distribution of knowledge diffusion. We will show how these factors can be classified as follow: (1) learning strategies adopted by heterogeneous agents; (2) network architecture within which the interaction takes place; (3) geographical distribution of agents and their relative initial levels of knowledge. We shall also attempt to single out the relative effect of each of the above factors.Knowledge, Network, Small world, Experiment, Simulation.

    Knowledge Diffusion and Innovation: Modelling Complex Entrepreneurial Behaviours by Piergiuseppe Morone and Richard Taylor: A Response to the Review

    In this brief note we reply to C�sar Garc�a-D�az and Diemo Urbig who reviewed our book on Knowledge Diffusion and Innovation (Edward Elgar Publishing: Cheltenham, 2010). We take this opportunity to reaffirm our personal view on several relevant issues, such as the need for a holistic view in economics, the adoption of a pragmatic heuristic approach when dealing with complex socio-economic systems, the relevance of a \'prototype model\' to setting a rigorous conceptual framework and the proposition of a novel way of looking at knowledge and innovation.Knowledge Diffusion, Innovation, Agent-Based Model, Validation

    Conoscenza, nuove disuguaglianze e tecnologia dell'informazione

    Get PDF
    I recenti anni sono stati definiti come l'era della conoscenza; essa viene vista nell'interpretazione teorica come una delle determinanti principali dell'accumulazione, nel tempo, di un potenziale di sviluppo. Vi e' pertanto un sostanziale accordo sull'idea che la conoscenza sia un elemento fondamentale della crescita economica. Cio' che resta meno chiaro e' come tale conoscenza venga creata e diffusa; questo quesito e' particolarmente rilevante se si pensa che un significativo knowledge gap puo' attivare fenomeni di disuguaglianza, come viene evidenziato da esempi di divergente sviluppo tra paesi: il PIL della Corea del Sud in circa trent'anni e' cresciuto sei volte pi di quello del Ghana, anche grazie alla differente capacita' di acquisire ed utilizzare conoscenze. Pertanto in varie aree geografiche si e' manifestato un massiccio aumento della disuguaglianza tra paesi. Partendo da tali riflessioni, l'autore cerca di interpretare le ragioni di tale fenomeno, ponendo l'accento sui meccanismi di trasmissione e creazione di conoscenza. Utilizzando un recente approccio teorico ai problemi della disuguaglianza, emerge dal lavoro un filo logico che, nell'ambito di una crescente divaricazione salariale tra lavoratori qualificati e non, lega il progresso tecnologico alla accumulazione di capitale umano.
