Super Partes? Assessing the Effect of Judicial Independence on Entry
No full textIncumbents can enjoy a cost advantage vis-à-vis new entrants and so deter new firm entry by establishing and leveraging connections with the judicial system. Connected firms may in fact avoid fully complying with the costly norms implied by a law, a regula- tion, or a contract. At the same time, they can also credibly threaten to sue new entrants. Therefore, a change in the institutional environment that diminishes the ability of incum- bent firms to establish judicial connections—i.e., an increase in judicial independence— can promote entrepreneurship. Exploiting reforms that change the way in which U.S. state judges are selected, we confirm that this is the case, and we show that this effect is more salient in states and industries where the likelihood of entering into a business dispute is higher. The paper also sheds some light on the mechanisms behind this effect
L'ambiente: dalle teorie economiche al management
No full textIl presente testo si propone di studiare i problemi ambientali nel contesto delle principali teorie economiche micro e macro e del management - che nel complesso costituiscono il corpus teorico fondamentale dell’economia ambientale -, tenendo altresì in considerazione quelle fonti normative che trovano nella tutela dell’ambiente la loro principale ragion d’essere. Quanto inquinamento siamo disposti ad accettare? Occorre tolleranza zero per i delitti ambientali? Quand’è che i delitti ambientali saranno considerati come delitti di lesa umanità? Perché dover dare un valore economico alla vita umana? Sono queste le domande centrali di partenza del libro e alle quali gli autori tentano di dare risposta
Super Partes? Assessing the Effect of Judicial Independence on Entrepreneurship
No full textWe study whether judicial independence from business interest groups promotes entrepreneurship. We argue that more judicial independence, by ensuring that courts do not favor connected parties in business disputes, induces more entry of new firms, as they face a lower risk of expropriation by powerful incumbents. In turn, this triggers the exit of established and less efficient firms, and, as a result, enhances the overall economy. In order to identify the effect of judicial independence on the outcomes of interest, we exploit exogenous longitudinal variations in the judicial selection system in U.S. states between 1977 and 2011. Empirical results broadly support our hypotheses
Direttiva IPPC-IED e il problema delle implementazione delle BAT nell'Unione Europea
No full textL'articolo esamina in modo critico la policy ambientale della direttiva IPPC-IED, (Integrated Pollution Prevention Control – Industrial Emission Directive), ed in particolar modo, gli aspetti di attuazione delle BAT (Best Available Technologies). Quest’ultime sono indicate in fase di autorizzazione IPPC per garantire un’economia a basso impatto ambientale, sia in termini di inquinamento e sia in termini di consumo delle risorse
Un cattivo sovrano in Polluce
No full textJulius Pollux, lexicographer in Athens under the emperor Commodus, devotes a chapter of the
Onomasticon to a bad emperor. Many references are in the works of greeks historians, especially of Cassius Dio, contemporary of Julius Pollux

No full textThe carbon market and its efficiency
No full textThis paper overviews the efficiency of the European carbon market EU-ETS (European Union Emission Trading System or Scheme) connected with projects JI (Joint Implementation) and CDM (Clean Development Mechanism). As known, these three flex mechanisms enable industries to earn emission reduction credits to be traded on the market. The aim of this paper is to highlight some relevant problems such us price volatility, environmental integrity, financial tools, etc., present since the Kyoto Protocol came into force in 2005. These aspects are here fully debated. The conclusion supports the idea that the CDM and JI projects have little connection with the principle of environmental sustainabilit
Tangible interfaces in virtual environments for industrial design
No full textIn the fields of industrial design and car manufacturing the
creation of 3D curves plays a fundamental role within the design
process: it allows the improvement of the visual appeal of
artifacts, it enhances ergonomics and the product’s commercial
competitiveness through product differentiation. When flexibility
and intuition are to be privileged it is fundamental to achieve
natural, intuitive, mathematically correct, creation and
modification of surfaces.
The scientific aim of this research is the development of an
innovative metaphor to modeling of 3D curves which maintains
the natural expertise of the designer. The major contribution of
this paper is the capability of the system to create and modify the
curve naturally, without mathematical artifices, within the limits
set by the use of Bezier curves.
The proposed metaphor combines the benefits of two
acknowledged techniques referred to as the Digital Tape Drawing
and the Eraser Pen, which allow the real-time modification of the
curve. The integrated adoption of tangible interfaces and
innovative mathematical tools, combined with the adoption of
semi-immersive environment and lightweight interaction devices,
delivers intuitive curve creation for free-form modeling within the
virtual scene. The paper describes the details of the algorithm
developed and it highlights its strengths during the styling phase
