DESCRIPTION:3.00 pm – 3:40 pmMeasuring the efficiency of Italian airports: 
 How to counter unexpected shocksGraziella Bonanno\, Sapienza Università di
  RomaAbstractThis paper investigates the efficiency of Italian airports. I
 t uses a sample of 45 airports and covers the period from 2007 to 2016. Th
 e contributions of the analysis are twofold. The first novelty comes from 
 the consideration of low cost flights operated to/from Italian airports. T
 o the best of our knowledge\, this aspect has been considered in the case 
 of American airports. Since American airports are mostly public\, while It
 alian airports are mostly private\, we expect different findings as to the
  efficiency of vertical relationship between airports and airlines. Second
 ly\, the estimations of  efficiency refer to some recent methodological ad
 vances in the Stochastic Frontier approach (SFA) which relax the hypothesi
 s of independence between the two error terms of a stochastic frontier\, t
 hat is\, the erratic and the inefficiency components (Bonanno et al.\, 201
 7). In a context like the airport industry current managerial decisions ar
 e influenced by past natural shocks\, thereby rendering the assumption of 
 independence too stringent. A shock may impact on the random error compone
 nt and\, at the same time\, may affect future decisions\, influencing the 
 inefficiency component. This makes the random noise and the inefficiency o
 f airport two dependent variables rather than independent as assumed in st
 andard SFA models. Our findings provide airport managers with a robust too
 l to suitably deal with unexpected frequent shocks and increase efficiency
   3.40 pm – 4:20 pmTransition Towards a Green Economy in Europe: Innovatio
 n and Knowledge Integration in the Renewable Energy SectorChiara Conti\, S
 apienza Università di RomaAbstractA major concern regarding innovation in 
 clean technologies in the EU is that the fragmentation of its innovation s
 ystem may hinder knowledge flows and\, consequently\, spillovers across me
 mber countries. A low intensity of knowledge flows across EU states can ne
 gatively impact their technological base\, suppressing opportunities for f
 urther innovations and slowing the movement towards the technological fron
 tier. This paper investigates the fragmentation of the EU innovation syste
 m in the field of renewable energy sources (RES) by estimating the intensi
 ty and direction of knowledge spillovers over the years 1985-2010. We modi
 fy the original double exponential knowledge diffusion model proposed by C
 aballero and Jaffe (1993) to provide information on the degree of integrat
 ion of EU countries’ innovation efforts and to assess how citation pattern
 s changed over time. We show that EU RES inventors have increasingly built
  “on the shoulders of the other EU giants”\, intensifying their citations 
 to other member countries and decreasing those to domestic inventors. Furt
 hermore\, the EU strengthened its position as source of RES knowledge for 
 the US. Finally\, we show that this pattern is peculiar to RES\, with othe
 r traditional (i.e. fossil-based) energy technologies and other radically 
 new technologies behaving differently.  4.20 pm – 5:00 pmThe international
 ization of State Owned Enterprises and the moderating role of varieties of
  capitalismRiccardo Marzano\, Politecnico di MilanoAbstractThis article co
 ntributes to shedding light on how the internationalization process of sta
 te owned enterprises (SOEs) is influenced by the degree of state involveme
 nt in ownership and by the home country’s institutional architecture. Inte
 grating international business studies with both recent theoretical develo
 pments on the varieties of state capitalism and the debate among comparati
 ve economists on the institutional varieties of capitalism\, we claim that
  the state per se neither facilitates nor hinders the internationalization
  expansion of SOEs\, when compared with each other and with privately owne
 d enterprises (POEs). Rather\, the influence of the state is contingent on
  the home country’s form of capitalism. With reference to the well-establi
 shed tripartite taxonomy of Western capitalism (liberal\, coordinated\, an
 d state-influenced market economies)\, we contend that SOEs’ propensity to
  internationalize is lower (higher) than that of POEs in liberal (coordina
 ted) market economies\, whereas in state-influenced market economies no di
 fferences are expected. Our empirical analysis on the 1995-2014 evolution 
 of the internationalization degree of a sample of European enterprises ope
 rating in the energy and telecommunications sectors confirms our expectati
 ons. This article adds to the literature that studies the influence of nat
 ional institutions on firms’ internationalization strategies and has some 
 major implications for both SOEs’ managers and policy-makers.
