No full textModelling bank lending in the euro area: A non-linear approach
No full textThis paper investigates possible non-linearities in the response of bank lending to monetary policy shocks in the euro area. The credit market is modelled over the period 1985-2005 by means of an Asymmetric Vector Error Correction Model (AVECM) involving four endogenous variables (loans to the private sector, real GDP, lending rate, and consumer price index) and one exogenous variable (money market rate). The main features of the model are the existence of two co-integrating equations representing the long-run credit demand and supply and the possibility for loading and lagged-term coefficients to assume different values depending on the monetary policy regime (easing or tightening). The paper finds that the effect on credit, GDP, and prices of a monetary policy tightening is larger than the effect of a monetary policy easing. This result supports the existence of an asymmetric broad credit channel in the euro area.monetary policy transmission, credit market, credit view, asymmetries
Orbital forcing of carbonate versus siliceous productivity in the late Albian–early Turonian (Umbria-Marche Basin, central Italy)
No full textWe applied a cyclostratigraphic analysis to a late Albian – late Cenomanian Tethyan section (Monte Petrano) from the Umbria-Marche Basin. Starting from a high-resolution (mm-scale) lithological log, estimated calcium carbonate contents were used as input data for cyclostratigraphy. The orbital tuning was based on long and short eccentricity, obliquity and precessional components and was tied to a radiometric age of 93.9 ± 0.15 Ma (2σ) of the Cenomanian/Turonian boundary. The estimated variations in sedimentation rates allowed for constructing an anchored astrochronology of the composite Albian – Cenomanian δ13C record. Our estimates of the total duration of the Albian and Cenomanian stages are about 14.20 ± 0.86 Myr and about 4.94 ± 0.35 Myr, respectively. The Aptian/Albian boundary lies at 113.04 ± 0.94 Ma and the Albian/Cenomanian boundary at 98.84 ± 0.35 Ma. Moreover, according to our results, OAE1d lasted about 1.21 ± 0.17 Myr (from 100.11 ± 0.41 Ma to 98.90 ± 0.35 Ma). We obtained an astronomical tuned age of 96.28 ± 0.28 Ma to 96.12 ± 0.27 Ma for the MCE I with a total duration of the event of about 166 ± 20 kyr. Astronomical cyclicities and climatic conditions exerted a direct influence on the depositional style of the studied geological record. Orbitally-paced variation in insolation controlled the variability in monsoon intensity, with maximum in monsoon strength during insolation maxima. Under humid climatic conditions, the orbitally-paced variations in summer monsoon precipitation controlled the amount of runoff and transportation of fine-grained detrital sediments in the basin, thus modulating the alternate deposition of marls and carbonate-rich sediments. During arid climate periods, the fluctuations in winter monsoon intensity controlled the variations in wind-blown dust availability and the fluctuations in ocean fertilization with times of enhanced siliceous productivity under eutrophic conditions and carbonate productivity under oligotrophic conditions
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Securitisation and the bank lending channel
No full textThe dramatic increase in securitisation activity has modified the functioning of credit markets by reducing the fundamental role of liquidity transformation performed by financial intermediaries. We claim that the changing role of banks from “originate and hold” to “originate, repackage and sell” has also modified banks’ abilities to grant credit and the effectiveness of the bank lending channel of monetary policy. Using a large sample of European banks, we find that the use of securitisation appears to shelter banks’ loan supply from the effects of monetary policy. Securitisation activity has also strengthened the capacity of banks to supply new loans but this capacity depends upon business cycle conditions as well as upon banks’ risk positions. In this respect the recent experience of the sub-prime mortgage loans crisis is very instructive.asset securitisation, bank lending channel, monetary policy
