Linking Metatraits of the Big Five to Well-Being and Ill-Being: Do Basic Psychological Needs Matter?

There is considerable evidence that two higher order factors underlie the Big-Five dimensions and that these two factors provide a parsimonious taxonomy. However, not much empirical evidence has been documented as to the extent to which these traits relate to certain psychological constructs. In this study, we tested a structural model to investigate the individual differences in well-being and ill-being by examining the mediating effects of autonomy, relatedness, and competence on the extent to which two higher order factors of personality, namely Stability and Plasticity, are linked to life satisfaction and depression. In testing the model, we controlled for the effects of current affect. A large community sample participated and responded to self-measures of The Big-Five personality, basic psychological needs satisfaction, satisfaction with life, depressive symptoms, and positive and negative affect. The results revealed that satisfaction of basic psychological needs fully mediated the relationship between Plasticity and life satisfaction, as well as depression. It also fully mediated the relationship between Stability and life satisfaction, and partially mediated the relationship between Stability and depression.     

A Comparison of Two Group Classification Approaches to Fat-tailed and Skewed Data

The problem of two-group classification has implications in a number of fields, such as medicine, finance, and economics. This study aims to compare the methods of two-group classification. The minimum sum of deviations and linear programming model, linear discriminant analysis, quadratic discriminant analysis and logistic regression, multivariate analysis of variance (MANOVA) test-based classification and the unpooled T-square test-based classification methods, support vector machines and k-nearest neighbor methods, and combined classification method will be compared for data structures having fat-tail and/or skewness. The comparison has been carried out by using a simulation procedure designed for various stable distribution structures and sample sizes.

Confessions without guilt: public confessions of state violence in Turkey

Drawing on Austin’s speech act theory and on related theories of performativity and positioning, this article analyses the public confessions during the 1990s by three prominent state actors in Turkey about their direct involvement in state crimes against Kurds and left-wing political opponents. All three cases received significant media attention at the time. The aim of the article is not only to shed new light on those specific confessions by the perpetrators within the Turkish context, but also to develop further theoretical insights into the phenomenon of public confessions as such. Whilst confessions of this kind are often welcomed and portrayed as truth-statements that are cathartic and enable society to move forward, this analysis demonstrates that the reality is often more complex as the confessions in question tend to go hand in hand with a disavowal of individual responsibility by the perpetrators involved.

A politico-economic model of aging,technology adoption and growth

This paper provides a politico-economic theory that explains how an economy evolves when the longevity of its citizens is jointly determined with the process of economic development. We propose a three-period overlapping generation model where agents’ decisions embrace two dimensions: a private choice about education and a public one on innovation policy. We find that (a) poverty traps can emerge in human capital accumulation, (b) higher life expectancy increases the incentive to innovate for both young and adults, (c) different political configurations can arise depending on endogenous demographic structures and (d) the steady state can entertain both innovation and its absence.     

Doing Well by Returning to the Origin. Mission Drift,Outreach and Financial Performance of Microfinance Institutions

The majority of studies discussed the existence of a trade-off between financial performance and outreach, pointing out those MFIs that look for higher profits lead to lower outreach. Another stream of research discussed the phenomena of mission drift, which see MFIs leave from their social mission, which is to provide micro financial services to break the cycle of poverty by reducing financial exclusion and move away from the traditional microcredit business model by three different ways. The paper contribute to the debate focussing the impact of mission drift phenomena on both financial performance and outreach of MFIs. This paper uses a dataset of 194 microfinance institutions (MFIs), 788 annual ratings from 2001 to 2010, collected by MicroFinanza Rating, an international MFIs’ rating agency, to study and test three hypotheses on the relationship between mission drift, financial performance and outreach of MFIs. Data analysed with mixed effect regressions shows that a trade-off exist between financial performance and outreach. Results show that mission drift positively impacts on financial performance but it reduces outreach. MFIs should be encouraged to clearly define if their main aim is to assure remuneration of shareholders or if they want to contribute to the outreach of poor.     

Variance Estimation for Fractional Brownian Motions with Fixed Hurst Parameters

Some real-world phenomena in geo-science, micro-economy, and turbulence, to name a few, can be effectively modeled by a fractional Brownian motion indexed by a Hurst parameter, a regularity level, and a scaling parameter σ², an energy level. This article discusses estimation of a scaling parameter σ² when a Hurst parameter is known. To estimate σ², we propose three approaches based on maximum likelihood estimation, moment-matching, and concentration inequalities, respectively, and discuss the theoretical characteristics of the estimators and optimal-filtering guidelines. We also justify the improvement of the estimation of σ² when a Hurst parameter is known. Using the three approaches and a parametric bootstrap methodology in a simulation study, we compare the confidence intervals of σ² in terms of their lengths, coverage rates, and computational complexity and discuss empirical attributes of the tested approaches. We found that the approach based on maximum likelihood estimation was optimal in terms of efficiency and accuracy, but computationally expensive. The moment-matching approach was found to be not only comparably efficient and accurate but also computationally fast and robust to deviations from the fractional Brownian motion model.     

On Decomposing Net Final Values: Eva,Sva and Shadow Project

A decomposition model of Net Final Values (NFV), named Systemic Value Added (SVA), is proposed for decision-making purposes, based on a systemic approach introduced in Magni [Magni, C. A. (2003), Bulletin of Economic Research 55(2), 149–176; Magni, C. A. (2004) Economic Modelling 21, 595–617]. The model translates the notion of excess profit giving formal expression to a counterfactual alternative available to the decision maker. Relations with other decomposition models are studied, among which Stewart’s [Stewart, G.B. (1991), The Quest for Value: The EVA™ Management Guide, Harper Collins, Publishers Inc]. The index here introduced differs from Stewart’s Economic Value Added (EVA) in that it rests on a different interpretation of the notion of excess profit and is formally connected with the EVA model by means of a shadow project. The SVA is formally and conceptually threefold, in that it is economic, financial, accounting-flavoured. Some results are offered, providing sufficient and necessary conditions for decomposing NFV. Relations between a project’s SVA and its shadow project’s EVA are shown, all results of Pressacco and Stucchi [Pressacco, F. and Stucchi, P. (1997), Rivista di Matematica per le Scienze Economiche e Sociali 20, 165–185] are proved by making use of the systemic approach and the shadow counterparts of those results are also shown.     

The Serbian Banking System: Recent Development and Major Players

The paper analyzes the banking system of Serbia. First, we briefly overview the institutional and legal framework of the banking system and describe the main structural features of the sector. Then we discuss the evolution in traditional banking intermediation, and outline the main features of the banking competitive environment, focusing on the transformations in ownership structure of banks, especially on the increasing importance of foreign ownership, and summarising the key characteristics of major players.
