Questo libro racconta il doppio depistaggio che si è dispiegato attorno all’omicidio di Pasolini: uno volto a sviare le indagini, l’altro a tenere nascosti alcuni contenuti-chiave di Petrolio, il romanzo che Pasolini stava scrivendo quando fu ucciso
Food exporters in global value chains: Evidence from Italy
No full textThis paper offers a firm level perspective of global value chain participation in the food industry. We single out some stylized facts on food global value chains and the Italian food industry. Exploiting a very rich and original dataset, based on a 2011 survey of 25,090 Italian firms operating in manufacturing and related services, we characterize the food industry, describing its main strengths and weaknesses, and analyze the links between the probability to export and the value chain participation. Our results show that participating in a value chain significantly increases the probability to export. This is particularly true for small firms in the industrial food value chain and for firms positioned downstream. Participating in distribution chains, for instance being able to sell products through large supermarkets, also significantly contributes to internationalization. These results can have important implications in terms of trade policy: tariffs and other protection measures are cumulative when intermediate inputs are traded across borders multiple times. Hence, protection can end up in a significantly higher cost of finished goods. When discussing trade policy therefore, it is crucial to "think value chain"
Governance, value chain positioning and firms’ heterogeneous performance: The case of Tuscany
No full textThe recent trade literature has shown how incomplete contracts can shape firms’ boundary and the decision of whether to outsource or integrate vertically. Related evidence and conceptualizations from the business literature show that buyer-supplier relations in global value chains can take several governance structures, depending on the degree of vertical coordination and power relations between firms. Building upon these two non-competing strands of the literature, we construct a taxonomy of firms that considers their positioning (upstream or downstream), their belonging to domestic or global value chains and the type of relations they entertain with other firms. We apply our taxonomy to the 2011 census of firms operating in Tuscany. We first describe regional characteristics and then study how positioning and governance affect firms’ decisions and performance. Our results show that firms in hierarchical value chains are more productive than those in market chains; that firms involved in global value chains outperform the one outside or in domestic value chains, and, finally, that firms which are both suppliers and buyers in a value chain have the highest productivity premium

Dual nature of the ferroelectric and metallic state in LiOsO3
No full textUsing density functional theory we investigate the lattice instability and electronic structure of recently discovered ferroelectric metal LiOsO3. We show that the ferroelectric-like lattice instability is related to the Li-O distortion modes while the Os-O displacements change the d-p hybridization as in common ferroelectric insulators. Within the manifold of the d orbitals, a dual behavior emerges. In the ferroelectric transition the empty e(g) orbitals change their hybridization with the oxygen p orbitals, while the t(2g) orbitals are responsible for the metallic response. Interestingly, these orbitals are nominally half filled by three electrons, a configuration which suffers from strong correlation effects even for moderate values of the screened Coulomb interaction
Electronic Correlations Stabilize the Antiferromagnetic Mott State in Cs3C60
No full textCs3C60 in the A15 structure is an antiferromagnet at ambient pressure in contrast with other super-conducting trivalent fullerides. Superconductivity is recovered under pressure and reaches the highest critical temperature of the family. Comparing density-functional calculations with generalized gradient approximation to the hybrid functional of Heyd, Scuseria, and Ernzerhof, which includes a suitable component of exchange, we establish that the antiferromagnetic state of Cs3C60 is not due to a Slater mechanism, and it is stabilized by electron correlation. Pressure reduces the stability of the antiferro-magnetic state. Our findings corroborate previous analyses suggesting that the properties of this compound can be understood as the result of the interplay between electron correlations and Jahn-Teller electron-phonon interaction
