We examine how relationship lending affects firm performance using a panel dataset of about 70,000 small and medium Spanish firms in the period 1993-2004. We model firm performance jointly with the firm's choice of the number of bank relationships. Controlling for firm fixed effects and using instrumental variables for the decision on the number of bank relationships, we find that firms maintaining exclusive bank relationships have lower profitability. The result is consistent with the view that banks appropriate most of the value generated through close relationships with its borrowers as long as they do not face competition from other lenders.

L'existència dels parlars juvenils ens recorda el fet que totes les formes de cultura, i les identitats mateixes de les persones, van estretament lligades a les maneres de parlar que els són pròpies. El que segueix és doncs una reflexió sobre aquest lligam, aquestes relacions tan estretes entre les cultures i les identitats per una banda, i les maneres de parlar i les llengües per l'altra. La primera part del llibre tracta sobre les diverses identitats de gènere que vaig detectar dins els grups estudiats. El lector es preguntarà potser què és això de les identitats de gènere, i per què són tan importants. Els estudis del gènere tracten sobre el funcionament de la divisió sexual en la nostra societat, és a dir, sobre els diversos papers que homes i dones tenen en el mercat laboral, en la política, en la família, etc. A partir de tots aquests conceptes, a la segona part del llibre procediré a explicar quines identitats i ideologies anaven associades a les diverses formes de parlar (argot juvenil, accent andalús) i a l'ús de les llengües catalana i castellana. I aquí es veurà també perquè és important estudiar les diverses veus que apareixen en la nostra parla.

Sardinia is the second largest island in the Mediterranean and, together with Corsica and nearby mainland areas, one of the top biodiversity hotspots in the region. The origin of Sardinia traces back to the opening of the western Mediterranean in the late Oligocene. This geological event and the subsequent Messinian Salinity Crisis and Pleistocene glacial cycles have had a major impact on local biodiversity. The Dysdera woodlouse hunter spiders are one of the most diverse ground-dweller groups in the Mediterranean. Here we describe the first two species of this genus endemic to Sardinia: Dysdera jana sp. n. and Dysdera shardana sp. n. The two species show contrasting allopatric distribution: D. jana sp. n. is a narrow endemic while D. shardana sp. n. is distributed throughout most of the island. A multi-gene DNA sequence phylogenetic analys based on mitochondrial and nuclear genes supports the close relationships of the new species to the type species of the genus Dysdera erythrina. Age estimates reject Oligocene origin of the new Dysdera species and identify the Messinian Salinity Crises as the most plausible period for the split between Sardinian endemics and their closest relatives. Phylogeographic analysis reveals deep genetic divergences and population structure in Dysdera shardana sp. n., suggesting that restriction to gene flow probably due to environmental factors could explain local speciation events.
