41. Inverted-U aggregate investment curves in a dynamic game of advertising - Lambertini, Luca; Zaccour, Georges
We revisit the relationship between market power and firms' investment incentives in a noncooperative differential oligopoly game in which firms sell differentiated goods and invest in advertising to increase the brand equity of their respective goods. The feedback equilibrium obtains under open-loop rules, and aggregate expenditure on goodwill takes an inverted-U shape under both Cournot and Bertrand behaviour, provided product differentiation is sufficiently high. Total industry expenditure is higher under Cournot competition.

42. Competition and Screening with Skilled and Motivated Workers - Barigozzi, Francesca; Nadia, Burani
We study optimal contracts offered by two firms competing for the exclusive services of one worker, who is privately informed about her ability and her motivation. Firms differ both in their production technology and in the mission they pursue and a motivated worker is keen to be hired by the mission-oriented firm. We find that the matching of worker types to firms is always Pareto-efficient. When the difference in firms’ technology is high, only the most efficient firm is active. When the difference is not very high, then agent types sort themselves by motivation: the mission-oriented firm hires motivated types...

43. Adjustment to Equilibrium after a Demand Shock: A Strategic Interaction View - Lambertini, Luca; Marattin, Luigi
In this paper we verify the functioning of the standard neoclassical adjustment to equilibrium after a demand shock in a non-cooperative simultaneous Cournot duopoly with complete, symmetric and imperfect information. Our results show that in such a framework the adjustment to the long-run level of output by the entire industry or part of it is no longer guaranteed. We show that the size of the demand shock determines the nature and number of equilibria generated by strategic interaction, whereas the post-adjustment real wage level determines which equilibrium is actually obtained.

44. Quale insegnamento dalla "epopea" dell'amianto? - Avio, Alberto; Barbini, Francesco Maria; Bertazzi, Pier Alberto; Carnevale, Francesco; Maggi, Bruno; Rulli, Giovanni
What lessons can be drawn from the “epic history” of asbestos? How this emblematic case can help the reflection on prevention in the workplace? The subjects of primary prevention, risk management, laws and regulation protecting safety and health in the workplace are discussed from different points of view, such as history of medicine, epidemiology, occupational and preventive medicine, labour law, organization theory, science methodology. These collected papers are aimed at proposing prevention strategies allowing to avoid mistakes and pitfalls like the ones that characterized the history of asbestos.

45. Cournot Competition and “Green” Innovation: An Inverted-U Relationship - Lambertini, Luca; Poyago-Theotoky, Joanna; Tampieri, Alessandro
We evaluate the relationship between competition and innovation in an industry where production is polluting and R&D has the aim to reduce emissions. We build up an oligopoly model where n firms compete in quantities and decide their investment in green R&D. When environmental taxation is exogenous, the investment in green R&D always increases with the number of firms in the industry. We analyse next the case where taxation is endougenously determined by a regulator with the aim to maximise social welfare. An inverted-U relationship exists under reasonable conditions, and it is driven by the presence of spillovers.

46. Management della verità. Il valore della persona nella formazione, nelle organizzazioni e nel lavoro - Grisi, Cesare
"IL MANAGEMENT DELLA VERITA'" è uno studio sulla tematica del valore della persona nel contesto lavorativo, presa in considerazione da molteplici punti di vista. Ha un taglio multidisciplinare e sottopone il soggetto della trattazione a diverse chiavi di lettura, evitando gli stereotipi della specializzazione irrelata. Lo spunto che serve da abbrivio è di dare una spiegazione ad un fenomeno assai diffuso nel mondo del lavoro, nelle organizzazioni e nella formazione: il compulsivo ricorso al "valore della persona". La perplessità che deriva dall’uso di questo leitmotiv scaturisce, a fronte di una analisi documentata da uno studio bibliografico comparativo, dalla discrasia tra...

47. On the effect of social norms to reduce pollution - Mantovani, Andrea; Tarola, Ornella; Vergari, Cecilia
We analyse how market competition in a vertically differentiated polluting industry is affected by product variants that comply at different levels with "green" social norms. A green consumption behaviour is considered as a byword of good citizenship. Consumer preferences depend on a combination of hedonic quality and compliance with the norms. Assuming that the high hedonic quality variant complies less with the norms than the low hedonic quality one, we characterize the different equilibrium configurations, depending on the perceived intensity of such norms. Then, we focus on the role that institutions may have in using these norms to reduce pollution...

48. Costruire comunità ospitali e sostenibili. Nuove sfide per la Psicologia di Comunità
Il volume presenta gli atti del X Convegno Nazionale della Società Italiana di Psicologia di Comunità (SIPCO), che si è svolto a Cesena dal 19 al 21 giugno 2014. "Ospitalità" e "sostenibilità" sono i temi scelti per questa edizione del Convegno: concetti che si è voluto assumere come stimolo a rivisitare – attraverso la riflessione teorica e la presentazione di esperienze concrete di ricerca ed intervento – due temi centrali per la disciplina, tra loro strettamente interconnessi: quello della "relazione con l’altro" (che comprende il "diverso" da sé, per provenienza, cultura, genere, condizione di salute, ecc.) e quello del benessere....

49. Which attitudes will make us individually and socially happier and healthier? A cross-culture and cross-development analytical model - Zagonari, Fabio
This paper describes a dynamic system for the interrelationships between happiness and health that considers three main attitudes to life: α, β, and γ for Aristotelian, Epicurean, and Stoic, respectively. All variables that have been shown by empirical and theoretical studies to affect individual health and happiness are included (i.e., employment, occupation, education, ethical freedom, equity in achievements). Three main approaches are considered: behavioural and statistical ex-ante, and ex-post behavioural. I develop the model to rank the three attitudes in terms of health for a given happiness level, and consequently, provide insights into which attitude should be adopted by each...

50. Tradurre Figure / Translating Figurative Language
Tradurre Figure / Translating Figurative Language offers 30 original contributions on the interlingual translation of figurative language. The chapters were first presented at an international conference held at the University of Bologna in December 2012 and have been selected through a double peer-reviewed process. Why figurative language in translation? Essentially because figurative language – and the contributions in this book can be seen to prove it – may often foreground the complexities of the translation process, as well as the strong link between language and culture that this process has to renegotiate. Written in either English or Italian, the different...

51. Cartel Size and Collusive Stability with Non-Capitalistic Players - Delbono, Flavio; Lambertini, Luca
A well established belief both in the game-theoretic IO and in policy debates is that market concentration facilitates collusion. We show that this piece of conventional wisdom relies upon the assumption of profit-seeking behaviour, for it may be reversed when firms pursue other plausible goals. To illustrate our intuition, we investigate the incentives to tacit collusion in an industry formed by Labor-Managed (LM) enterprises. We characterize the perfect equilibrium of a supergame in which LM firms play an infinitely repeated Cournot game. We show that the critical threshold of the discount factor above which collusion is stable (i) is lower...

52. Intergenerational altruism and house prices: evidence from bequest tax reforms in Italy - Bellettini, Giorgio; Taddei, Filippo; Zanella, Giulio
We identify the degree of intergenerational altruism in an OLG framework à la Barro exploiting the quasi-experimental variation generated by reforms of bequest taxation (estate or inheritance tax, in the U.S.) and taxes on inter vivos real estate donations (gift tax, in the U.S.) that were enacted in Italy between 2000 and 2001. Employing a unique data set containing information on the housing stock and house prices in 13 large Italian cities between 1993 and 2004, we identify the structural parameter of interest via the effect of changes in the tax rate on house prices. We find that the intergenerational...

53. The impact of floods on firms' performance - Coelli, Federica; Manasse, Paolo
We estimate the short-run impact of a major flood that hit the region of Veneto in 2010 on firms' performance. Using firm level data and a difference in difference approach we compare the value added growth of hit firms to the one of a control group of companies that are not exposed to the flood. The results indicate that the value added growth of affected firms is 6.9% higher two years after the flood. We further investigate the role of aid transfers in the aftermath of the disaster event. Considering both the flood and the aid treatment, we construct four...

54. R&D Policy and Schumpeterian Growth: Theory and Evidence - Minniti, Antonio; Venturini, Francesco
In recent years, a large body of empirical research has investigated whether the predictions of secondgeneration growth models are consistent with actual data. This strand of literature has focused on the longrun properties of these models by using productivity and innovation data but has not directly assessed the effectiveness of R&D policy in promoting innovation and economic growth. In the present paper, we fill this gap in the literature by providing a unified growth setting that is empirically tested with US manufacturing industry data. Our analysis shows that R&D policy has a persistent, if not permanent, impact on the rate...

55. Economic Behavior under Alcohol Influence: An Experiment on Time, Risk, and Social Preferences - Corazzini, Luca; Filippin, Antonio; Vanin, Paolo
We report results from an incentivized laboratory experiment to provide controlled evidence on the causal effects of alcohol consumption on risk preferences, time perception and altruism. Our design allows disentangling the pharmacological effects of alcohol intoxication from those mediated by expectations, as we compare behaviors of three groups of subjects: those participating to an experiment with no reference to alcohol, those exposed to the possibility of consuming alcohol but assigned to a placebo and those having effectively consumed alcohol. Once randomly assigned to one treatment, subjects were administered a series of consecutive economic tasks, being the sequence kept constant across treatments. After controlling for both...

56. Cultural Offer and Distance in a Spatial Interaction Model for Tourism - Patuelli, Roberto; Mussoni, Maurizio; Candela, Guido
Culture is more and more considered as an important driver of tourism. However, it is critical, for policymakers, to evaluate the potential returns from investments in culture and generally cultural offer, in particular in multiregion settings with a potentially inefficient distribution of cultural offer. Our paper focuses on the role of distance (between the tourist’s origin and destination regions) in mediating the tourism impact of cultural offer. This research question is investigated by means of a spatial interaction model, applied to the case of Italian domestic tourism. We find that distance indeed matters: a destination’s endowment in culture appears to be...

57. An Experiment on Retail Payments Systems - Camera, Gabriele; Casari, Marco; Bortolotti, Stefania
We study the behavioral underpinnings of adopting cash versus electronic payments in retail transactions. A novel theoretical and experimental framework is developed to primarily assess the impact of sellers’ service fees and buyers’ rewards from using electronic payments. Buyers and sellers face a coordination problem, independently choosing a payment method before trading. In the experiment, sellers readily adopt electronic payments but buyers do not. Eliminating service fees or introducing rewards significantly boosts the adoption of electronic payments. Hence, buyers’ incentives play a pivotal role in the diffusion of electronic payments but monetary incentives cannot fully explain their adoption choices. Findings...

58. Technology and costs in international competitiveness: from countries and sectors to firms - Dosi, Giovanni; Grazzi, Marco; Moschella, Daniele
This paper examines the determinants of international competitiveness at the level of sectors and firms. First, we address the relation between cost-related and technological competition in a sample of fifteen OECD countries. Results suggest that the countries’ sectoral market shares are indeed mainly shaped by technological factors (proxied by investment intensity and patents) while cost advantages/disadvantages do not seem to play any significant role. Next, we attempt to identify the underlying dynamics at the firm level. We do that for a single country, Italy, using a large panel of Italian firms, over nearly two decades. Results show that also at...

59. Environmental Law Survey 2013
Within the EGP Project “The Capacity Building of Environmental Justice and Guarding Environmental Rights in Western China”, the scholars of the University of Bologna, partner of the China University of Political Science and Law (CUPL) and its Center for Legal Assistance to Pollution Victims (CLAPV), have worked on an Environmental Law Survey so as to provide to the interested public –in particular, Chinese judges, lawyers, academics, and civil society as a whole – with the most interesting and recent judicial decisions or pieces of Environmental Law legislations developed in the most relevant legal fields. The choice has fallen on the...

60. Climate Change and Natural Disasters: Responding to the Philippines’ Haiyan tragedy - Ratha, Keshab Chandra; Mahapatra, Sushanta Kumar
The powerful typhoon Haiyan that swept across the Philippines is one of the strongest storms ever to make landfall, cut a path of destruction through several central islands, causing scores of people dead. The disaster's full impact is still revealing as the entire country has been caught in a state of shock and desperation. The devastation is really horrific with human tragedy. Responding to the disaster of such magnitude calls for both national and international hands to come forward for the affected people.
