Il volume si suddivide in cinque aree tematiche: Nuova teatrologia e Performance Studies; Le funzionidello spettacolo; Teatri e interazione sociale; Riviste e archivi. Tali campi d'intervento raccolgono, attorno al confronto fra Nuova teatrologia e Performance Studies, relazioni che riflettono la complessità dell'intero settore disciplinare, compenetrando il dinamismo della storiografia teatrale – capace di rivedere etichette e funzioni date per scontate – e le prospettive transculturali e culturologiche dei Performance Studies.

We revisit Fujiwaraís (2008) differential duopoly game to show that the degenerate nonlinear feedback identified by the tangency point with the stationary state line is indeed unstable, given the dynamics of the natural resource exploited by firms. To do so, we fully characterise the continuum of nonlinear feedback solution via Rowat's (2007)method, characterising the infinitely many stable nonlinear feedback equilibria.
Questa terza raccolta degli scritti di Pierangelo Schiera riunisce testi usciti tra il 1976 e il 2013. Il volume riprende alcuni dei principali percorsi di ricerca che hanno finora caratterizzato la sua opera. In primo luogo quello centrato sul lungo processo di costituzione dello Stato moderno: esso viene indagato attraverso lo studio della ragion di Stato e del costituzionalismo. In questo terzo volume domina tuttavia l’attenzione per la costituzione della società moderna. All’interno di questo secolare processo la melancolia emerge come simbolo della condizione umana, ovvero di una individualità che deve costantemente inventarsi e disciplinarsi. La faticosa disciplina di questi...
Perfectionism can be healthy: striving for perfection requires the ability to selfregulate, namely willpower. This paper formalizes the intuitive relation between healthy perfectionism and willpower in the presence of temptation. The value of a menu of options for an individual with limited willpower corresponds to the lower bound of the value assigned to the same menu by a perfectionist, when temptation and perfectionism intensities are free to vary. Moreover, the higher the perfectionism strive, the higher the willpower. The relation between overwhelming temptation and the Strotz model is a particular case of the result. When there is uncertainty about temptation, we generalize Dekel and Lipman (2012) providing conditions...

This article investigates the role of the gender composition of selection committees and networks in promoting women in research activities. We exploit a novel data set on recruitment processes at entry-level research positions in a leading Italian research centre that mainly operates in hard science. We find some evidence of discrimination against women at non-tenured entry levels, which is attenuated (or even reversed) by the presence of a woman on the selection committee. However, the most important predictor for recruitment seems to be previous connections with the research centre, which also serves as an important mechanism for women to enter...

Does monitoring past conduct facilitate intertemporal cooperation? We designed an experiment characterized by strategic uncertainty and multiple equilibria where coordinating on the efficient outcome is a challenge. Participants, interacting anonymously in a group, could pay a cost either to obtain information about their counterparts, or to create a freely available public record of individual conduct. Both monitoring institutions were actively employed. However, groups were unable to attain higher levels of cooperation compared to a treatment without monitoring. Information about past conduct alone thus appears to be ineffective in overcoming coordination challenges.

This study reveals the existence of a causal link between the availability of money and an expanded scale of interaction. We constructed an experiment where participants chose the group size, either a low-value partnership or a high-value group of strangers, and then faced an intertemporal cooperative task. Theoretically, a monetary system was inessential to achieve cooperation. Empirically, without a working monetary system, participants were reluctant to expand the scale of interaction; and when they did, they ended up destroying surplus compared to partnerships, because cooperation collapsed in large groups. This economic failure was reversed only when participants managed to concurrently develop...
This paper offers a linguistic study within the domain of popular scientific discourse in the digital age. In particular, it is concerned with print and digital magazines and aims at investigating the process of ‘remediation’ from the printed page to the Web. More specifically, it focuses on headlines contained in the Table of Contents and argues that, when migrating from the page to the screen, they undergo a process of ‘intralingual’ translation. The paper seeks to demonstrate that the kind of shifts taking place show similarities to the linguistic-cultural changes occurring in ‘interlingual’ translation in the digital world. The theoretical background...

Disasters can be seen as magnifying glasses on the behavior of subjects and on their (preliminary and contextual) decision-making processes. In fact, the sudden and disruptive events connected with the disaster do not trigger “unusual” behaviors, instead they offer an accelerated and exaggerated representation of normal organizational behaviors and problems, allowing the observation of the whole process of actions and decisions involved. This contribution proposes a reflection on two case studies (the AZF disaster and the Indian Ocean tsunami) that deals with issues related to the identification and management of risks in an industrial setting and to the coordination of...
Workplace health is guaranteed by primary prevention, not by risk management. Primary prevention requires an activity of work analysis aimed at transforming work conditions in order to ensure the well-being of workers. Thus, knowledge about the possible, alternative work design conceptions is necessary in order to make the most adequate choices for prevention. Also, it is useful to reflect on the research traditions that pointed to such pathway, upon which the European directive 89/391 is based on. Such directive introduced obligations of primary prevention and work analysis for prevention. Knowledge and competencies for such purposes are available. However, national norms...

We study a class of games featuring payoff functions being parabolic cylinders where best reply functions are orthogonal and therefore the pure-strategy non-cooperative solution is attained as a Nash equilibrium in dominant strategies. We prove that the resulting threshold of the discount factor above which implicit collusion on the Pareto frontier is stable in the infinite supergames is independent of the number of players. This holds irrespective of whether punishment is based on infinite Nash reversion or one-shot stick-and-carrot strategy. We outline two examples stemming from economic theory and one from international relations.
This paper looks at the recent debt crisis in Greece and argues that the crisis exemplifies a sequence of systematic mistakes made by International Financial Institutions, mistakes whose consequences had been clearly anticipated at the time of the first bail-out and could have been avoided. I will argue that the “original sin” of international creditors has been that of refinancing, rather than partially writing off, the debt. This mistake has led to excessively restrictive policies, and has ultimately to interventions of bail-out/in much larger than those which would have solved the problem at the outset, causing unnecessary pain to the economy...

This paper examines the behaviour of public hospitals in response to the average payment incentives created by price changes for patients classified in different Diagnosis Related Groups (DRGs). Using panel data on public hospitals located within the Italian region of Emilia-Romagna, we test whether a one-year increase in DRG prices induced public hospitals to increase their volume of activity, and whether a potential response is associated with changes in waiting times and/or length of stay. We find that public hospitals reacted to the policy change by increasing the number of patients with surgical treatments. This effect was smaller in the two years after the policy change than...

We study a broad class of dynamic consumer problems and characterize the short and long-run response of the demand for a good to a permanent increase in its market price. Such response can be non-monotonic over time, and the short and long-run price-elasticity of demand may have opposite sign. This is a testable prediction and can arise even in the absence of income effects. Our results are robust to a variety of settings that are commonly used in the economic literature, and have relevant policy implications. We provide illustrative applications to models of human capital and labor supply, addiction, habit and taste formation, health capital, and renewable resources.

A specific concept of structural model is used as a background for discussing the structurality of its parameterization. Conditions for a structural model to be also causal are examined. Difficulties and pitfalls arising from the parameterization are analyzed. In particular, pitfalls when considering alternative parameterizations of a same model are shown to have lead to ungrounded conclusions in the literature. Discussion of observationally equivalent models related to different economic mechanisms are used to make clear the connection between an economicall meaningful parameterization and an economically meaningful decomposition of a complex model. The design of economic policy is used for drawing some...

The aim of this paper is to study both the private and the social desirability of a mixed bundling strategy that generates a cost savings effect. We confirm that mixed bundling is the dominant strategy for multiproduct firms, although it may give rise to a prisoner’s dilemma. Moreover, we show that mixed bundling may maximise social welfare, provided that cost savings are sufficiently high. Finally, we highlight the parametric regions where the social and the private interests coincide, and those where they do not. The recent evolution of broadband telecommunications services provides an ideal framework to apply our theoretical predictions.

Beyond direct damages, terrorism creates fear and insecurity, potentially reducing support for democratic institutions if these are deemed inadequate to tackle the threat, and increasing support for military governments. To investigate this possibility, we use data from Pakistan, a country that experienced an exponential rise in terrorism since 2001. Exploiting individual level data on democratic attitudes and district level information on terrorist attacks, we document that persistent exposure to terrorism (and more broadly to violence) is associated to a significantly lower support for democratic values. Results are robust to the inclusion of different sets of controls, to sample splits based on...

Physicians are often alleged responsible for the manipulation of delivery timing. We investigate this issue in a setting that negates the influence of financial incentives behind “physician’s demand induction” but allows for “risk aversion” to medical errors and “demand for leisure” motivations. Working on a sample of women admitted at the onset of labor in a big public hospital in Italy we estimate a model for the exact time of delivery as driven by individual indication to receive Caesarean Section (CS) and covariates. We find that ICS does not affect the day of delivery but leads to a circadian rhythm in the likelihood of delivery. The...
This paper argues that fiscal convergence in the Euro area has been achieved at the expenses of real divergence in unemployment, investment and at, at least temporarily, growth. Statistical and econometric analysis support the view that the current fiscal framework has addressed debt sustainability concerns, but has imparted a pro-cyclical bias, which has contributed to economic divergence. The recent flexibility guidelines are a step in the right direction, but they are unlikely to have sizable effects. A reform of the fiscal framework and a mechanism for an intra-European unemployment insurance scheme is proposed.
