Credit scoring for individuals
No full textLending money to different borrowers is profitable, but risky. The profits come from the interest rate and the fees earned on the loans. Banks do not want to make loans to borrowers who cannot repay them. Even if the banks do not intend to make bad loans, over time, some of them can become bad. For instance, as a result of the recent financial crisis, the capability of many borrowers to repay their loans were affected, many of them being on default. That’s why is important for the bank to monitor the loans. The purpose of this paper is to focus on credit scoring main issues. As a consequence of this, we presented in this paper the scoring model of an important Romanian Bank. Based on this credit scoring model and taking into account the last lending requirements of the National Bank of Romania, we developed an assessment tool, in Excel, for retail loans which is presented in the case study.Credit scoring, credit risk, retail loans.
Equity Indexing: Conitegration and Stock Price Dispersion: A Regime Switiching Approach to market Efficiency
No full textThis paper examines the performance of a general dynamic equity indexing strategy based on cointegration, from a market efficiency perspective. A consistent return in excess of the benchmark is demonstrated over different time horizons and in different, real world and simulated stock markets. A measure of stock price dispersion is shown to be a leading indicator for the excess return, and their relationship is modelled as a Markov switching process of two market regimes. We find that the entire ‘abnormal return’ is associated with the high volatility regime, so the presence of a latent risk factor cannot be ruled out. Moreover, any market inefficiencies identified by the dynamic indexing model are temporary and occur only in special market circumstances. Our results have implications for equity fund managers: we shown how, without any stock selection, solely through smart optimisation and market timing, the benchmark performance can be significantly enhanced.cointegration, dispersion, efficient market hypothesis equity markets, index tracking, Markov switching
Flexibilizing the Termination of the Employment Contract: Pros and Cons
No full textThe changes in the Romanian Labour Code appear to be a way of implementing the concept of flexicurity in our system of law. And among all institutions changed by the new law, probably the one related to termination of employment has the most dramatic effect within labour relations and the very application of the principle of workers’ protection. Indeed, after eight years in force, the Labour Code has been changed, aiming at re-balancing the powers of the parties over the issue of the termination of the employment. These changes may lead to a new content of the concept of job security, and also to a new approach of the idea of career. The Government’s goal was to offer the possibility for the employers to dismiss and employ personnel more easily, allowing him/her to select best employees at a time of economic crisis. However, as a result of an analysis of how the flexicurity principles were applied in other states (especially in case of the new member states) one may be very much afraid that flexicurity cannot be obtained by just un-protect the employees and simplify the dismissal procedure. This is why the changes in the Labour Code, particularly with the intention to render more flexible the labour market and the contractual arrangements were received by trade unions, and by the entire society with deep concerns and skepticism. From the perspective of trade unions, if the implementation of the flexicurity concept seems to be successful in some of the European states, since it guarantees a certain level of protection, in Romania such a process would be disadvantageous for employees in terms of the special job stability they enjoyed. Flexicurity itself demands to be flexibly adapted – from case to case, from one state to another. One can even say that there are 27 ways of applying the concept of flexicurity within European Union... Which is the Romanian way, especially when it comes to the termination of the employment contract? The paper aims to put into light the advantages and disadvantages of the very recent changes in the Labour Code, and to configure a possible perspective in this regard.Labour law, employment contract, dismissal, flexicurity
Sources of Over-performance in Equity Markets: Mean Reversion, Common Trends and Herding
No full textIn the field of optimisation models for passive investments, we propose a general portfolio construction model based on principal component analysis. The portfolio is designed to replicate the first principal component of a group of stocks, instead of a traditional benchmark, thus capturing only the common trend in the stock returns. The main advantage of this approach is that the reduction of the noise present in stock returns facilitates the replication task considerably and the optimal portfolio structure is very stable. We analyse the portfolio performance over different time horizons and in different international equity markets. The strategy over-performs both equally weighted and price weighted benchmarks, even after transaction costs. A market premium, a value premium associated with mean reversion in stock returns, and a volatility premium which give the strategy characteristics of a benchmark enhancer, all explain the over-performance, but have time-varying contributions to it. A behavioural explanation for the mean reversion mechanism leads to the conclusion that the portfolio performance is influenced by the extent of investors herding towards the common trend in stock returns.common trends, mean revrsion, herding, principal component analysis, abnormal returns, value strategies, behavioural finance
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

The impact of investments in global financial crisis
No full textThe global financial crisis really started to show its effects in the middle of 2007 and into 2008. Around the world stock markets have fallen, large financial institutions have collapsed or been bought out, and governments in even the wealthiest nations have had to come up with rescue packages to bail out their financial systems. The most important task is to break the spiral of falling asset prices and falling demand and to revive the financial sector’s ability to provide credit for productive investment, to stimulate economic growth and to avoid deflation of prices. In this time of global financial crisis and recession it is essential to keep markets open to international trade and investment. The current global financial crisis is probably the most severe for the world’s financial system since the Great Depression in 1929. This crisis has gone far beyond the financial sector and has seriously affected the real economy. An ample evidence of its negative impacts on FDI has been observed.investment risk, mergers
