    The Economics of Gossip and Collective Reputation

    No full text
    This chapter deals with reputation with a strong focus on the reputation of firms—groups or coalitions. To that end, the chapter heavily draws on the economic literature. The first section illustrates the three main sources of reputation (i.e., individual, collective, and institutional) and shows how reputation develops, why it matters, and how it can be preserved. The section then focuses on collective and institutional reputations and discusses the major problems arising with them, that is, free-riding and opportunistic behavior. In the second section, we move to the relation between reputation and gossip. We discuss some basic principles of social learning and then move to the analysis of word-of-mouth, a notion that shares many similarities with gossip. Finally, we illustrate the link between individual and collective reputation, on the one hand, and word-of-mouth, on the other, where fakery is an important issue to be dealt with

    An Anticompetitive Effect of Eliminating Transport Barriers in Network Markets

    This paper examines the welfare effects of physically interconnecting two (network) markets that were previously separated. In each market a different set of capacity-constrained firms operate. Firms engage in a supergame and collude whenever it is rational for them to do so.We find that, under certain parametric restrictions, interconnection of the two markets reduces total welfare. The collusive horizon may extend from a single market to the overall integrated market. In such case, interconnection can be viewed as “exporting” collusion, rather than competition

    Il lavoro analizza la dinamica della specializzazione produttiva dell’Italia, in riferimento a quella degli altri principali Paesi industrializzati. La specializzazione comparata è calcolata, mediante un’apposita metodologia, in riferimento al livello del contenuto tecnologico della produzione, alla produttività del lavoro, agli investimenti in R&D e al grado di specializzazione verticale. I risultati dell’analisi vengono poi utilizzati per evidenziare elementi positivi e criticità del modello di specializzazione italiano, alla luce della dinamica dei modelli prevalenti nelle altre economie avanzate, offrendo infine alcune possibili interpretazioni e chiavi di lettura dei fenomeni descritti

    Recenti tendenze nei flussi di investimento estero delle economie emergenti. Sovereign wealth funds, imprese globali ed effetti per i paesi sviluppati

    No full text
    Il contributo presenta un’analisi delle conseguenze della recente crisi finanziaria e della relativa caduta di attività economica mondiale per i flussi di investimenti diretti esteri (IDE) che nel recente passato hanno costituito un fattore trainante fondamentale per la crescita e l’integrazione economica internazionale dei paesi emergenti. In una visione prospettica, si intende anche esprimere una valutazione degli effetti dei provvedimenti di eccezionale portata intrapresi per fronteggiare la situazione, non solo nel campo specifico della politica economica, ma anche di tipo regolatorio e di rafforzamento del coordinamento internazional

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
