Charmonium production in pp collisions with ALICE

The ALICE Collaboration studies the production of J/psi meson in pp collisions at the center-of-mass energies of 2.76 and 7 TeV at mid- and forward-rapidity. Inclusive production cross-sections are presented as a function of the collision energy, rapidity and transverse-momentum. The J/psi polarization measurements in the helicity and Collins-Soper frames are discussed. A novel result on the correlation between the collision charged particle multiplicity and J/psi yield is also shown.Comment: Talk given at the XX International Workshop on Deep-Inelastic Scattering (DIS2012), 26-30 March 2012, Bonn, Germany; 4 pages, 5 figure

Efficiency frontier on Japanese banking system

Since the emergence of the efficiency frontier techniques, a series of comparisons between the methods that led to the resultant efficiency has been presented. In this paper, data from 99 Japanese banks are used in order to prove the applicability of efficiency frontier analysis on the East-Asian financial system and to reveal the differences between inter and intra-regional banks, showing the effect of the present financial crisis on the efficiency of the studied banks. DEA and FDH are used to determine the technical and scale efficiency of the analyzed banks and also it compares fully efficient banks by ranking them through the super-efficiency notion.This work was co-financed from the European Social Fund through the Sectoral Operational Programme Human Resources Development 2007–2013, project number POSDRU 159/1.5/S/134197 “Performance and excellence in doctoral and postdoctoral research in Romanian economics science domain”

Nonlinear Considerations on Economic Systems’ Behaviour

Recent work done within the CNCSIS IDEI ID_1046 financed project has resulted in some ideas related to complex system behaviour and to certain ways in which this behaviour may be described using nonlinear models especially in relation to the evolution of the PIB and its components. We are presenting here some of these results and the way an oscillatory response in industrial production may be used to determine the associated differential equation of evolution.nonlinear models, decision, financial crisis

An assessment of the current account sustainability in Romania

This paper assesses the sustainability of the CA deficits in the New Member States (NMS) of European Union by estimating its structural component based on fundamentals. Using a large sample of panel data, we estimated long term relationships for the CA deficit and its fundamentals using two methods from the literature. The main conclusion of the paper is that in some countries there is an excessive CA deficit which should be adjusted. In the case of Romania, the results are showing that the structural CA could be between 6.3% and 10.9% of GDP, depending on the model used and the econometric procedure. Another important result of the paper is that the main drivers of the CA deficits in NMS are the economic convergence factors.structural CA deficit, convergence, relative income, Ricardian equivalence
