Privatisation Effects: Some Evidence from Serbia

This paper analyses basic outcome and effects of the privatisation process in Serbia. The first two parts of the paper deal with general achievements of the newest privatisation plan adopted in 2001. We present a brief background of the results of the privatisation process, analysing changes in the structure of enterprises by ownership status, the number of privatised firms, revenues earned through privatisation, the rate of successful transactions, and other relevant privatisation indicators. The paper continues with an analysis of a survey conducted within a sample of Serbian enterprises offering some evidence about performance, competition, and restructuring within different types of firms: socially owned, privatised, and new private. Contrary to the broadly accepted statement that new private firms are leading in transition economies, according to our estimation of the effects of the ownership type on firm performance, it appears that the privatised sector seems to be more active. A comparison of the survey results with findings for three neighbouring countries indicates that there is no general conclusion about the way how ownership status of a firm affects its performance in a transition economy. Although conclusions drawn from our survey analysis should be regarded as preliminary and limited by the quality of survey data and could not be generalised for the privatisation process in other transition countries, the findings we present, including the comparison made with other economies, could contribute to the understanding of both privatisation effects in general and effects remarkable for the Serbian economy.      

Serbian Judiciary and Transition: Recent Jurisprudence

This article examines the role and position of national courts during transitional periods with focus on and case study of the judiciary in Serbia. Courts in Serbia, as any other judiciary in transition, have undergone a staggering transformative process as illustrated by a chronology of human rights cases. On the other hand, courts in Serbia, as their counterparts worldwide, have also been the transformation force, as evidenced by recent jurisprudence in cases dealing more or less successfully with political assassinations, organized crime, corruption, war crimes, and international courts.     

Diathesis stress or differential susceptibility? testing longitudinal associations between parenting,temperament, and children's problem behavior

In this study we investigated longitudinal associations among parenting, children's temperamental negative affectivity, and internalizing and externalizing behavior. Second, we tested whether findings confirmed the diathesis‐stress model or differential susceptibility theory when conducting stringent interaction tests. The sample included 129 children and their families. Parenting quality (age 5) was measured by parent–child interaction observations. Parents evaluated child negative affectivity (age 7) and teachers reported on problem behavior (age 12). Multiple regression analyses revealed an interaction effect of negative affectivity and parenting on externalizing behavior. Visual inspection suggested ‘for better and for worse’ effects of parenting for children with negative affectivity. However, more stringent tests failed to show convincing evidence for differential susceptibility theory. For internalizing behavior, negative affectivity may render children vulnerable regardless of parenting. Our results point at the importance of further testing interaction effects to distinguish between differential susceptibility theory and the diathesis‐stress model.     

Exchange Rate Policy in Serbia

In August 2006, Serbia adopted an inflation targeting regime as its monetary regime. The initial period of implementation of this regime was characterized by an extremely high capital inflow and appreciation of the exchange rate of the dinar. Under such conditions, the selected monetary policy regime functioned well. However, at the end of 2008, when the global financial crisis caused the outflow of foreign capital, deterioration of foreign borrowing conditions and an increase in inflationary expectations, the dinar lost about 25 per cent of its value within a relatively short period, despite the interventions of the National Bank of Serbia in the foreign exchange market. Therefore, the authors of this paper raise a dilemma whether Serbia conducts an adequate policy of the exchange rate of the dinar. The authors point out that, at the moment, the policy of a free floating exchange rate is not adequate for Serbia. As an alternative, a two nominal-anchor regime—inflation and the exchange rate—is proposed.     

Broadcasting multiple messages in the 1-in port model in optimal time

In the 1-in port model, every vertex of a synchronous network can receive at most one message in each time unit. We consider simultaneous broadcasting of multiple messages from the same source or from distinct sources in such networks with an additional restriction that every received message can be sent out to neighbors only in the next time unit and never to already informed vertex. We use a general concept of level-disjoint partitions developed for this scenario. Here we introduce a subgraph extension technique for efficient spreading information within this concept. Surprisingly, this approach with so called biwheels leads to simultaneous broadcasting of optimal number of messages on a wide class of graphs in optimal time. In particular, we provide tight results for bipartite tori, meshes, hypercubes, Knödel graphs, circulant graphs. We also propose several open problems and conjectures.     

Sozialer Status und prosoziales Handeln: Ein Quasi-Experiment im Krankenhaus

Sociological, social psychological and economic research on the nexus between socioeconomic status and prosociality has so far provided contradictory findings. Some studies suggest that actors with a high socioeconomic status act more egoistically than actors with a lower socioeconomic status. Other studies find the opposite to be true. In contrast to previous research, which has worked with one-dimensional measures for socioeconomic status, this study examines prosocial behavior among occupational groups that have regular real-life contact in their workspace. About 150 hospital employees (physicians, nursing staff and nursing students) participated in experiments on altruistic giving in dictator games. The findings are surprisingly strong and clear-cut: Actors with higher social status act more prosocial than low-status actors. Furthermore, we find hardly any in-group effects, which have been repeatedly postulated. Our findings support the claim that high status promotes prosocial behavior. Also, they indicate that the inconclusive and in part contradictory findings provided by previous research stem to a considerable degree from deficient measures of social status and problematic experimental designs.     

Strengthening family cohesion through shared participation of family members in religious activities in Croatia

This article presents research results pertaining to an examination of the relation between family members’ participation in shared religious activities, perception of family cohesion, satisfaction with family life, and the level of conflict in the family. The survey of 503 parents of preschool children was conducted in Zagreb, Croatia. The findings demonstrate a significant correlation between shared participation of family members in religious activities, perception of family cohesion and satisfaction with family life, but not with perception of the level of conflict in the family. The results suggest that spiritual and religious matters are an important element necessary for understanding family functioning, and that cultivating shared religious practices in the family can contribute to the strengthening of family cohesion and greater satisfaction with family life.     

Cross-entropy method for estimation of posterior expectation in Bayesian VAR models

In this article, an importance sampling (IS) method for the posterior expectation of a non linear function in a Bayesian vector autoregressive (VAR) model is developed. Most Bayesian inference problems involve the evaluation of the expectation of a function of interest, usually a non linear function of the model parameters, under the posterior distribution. Non linear functions in Bayesian VAR setting are difficult to estimate and usually require numerical methods for their evaluation. A weighted IS estimator is used for the evaluation of the posterior expectation. With the cross-entropy (CE) approach, the IS density is chosen from a specified family of densities such that the CE distance or the Kullback–Leibler divergence between the optimal IS density and the importance density is minimal. The performance of the proposed algorithm is assessed in an iterated multistep forecasting of US macroeconomic time series.     

Uncovering the Truth: The Lake Perućac Exhumations in Eastern Bosnia

The aggression and genocide in Bosnia and Herzegovina (BiH) from 1992 to 1995 left an estimated 30,000 missing persons mainly Bosniaks (Bosnian Muslims). These victims consisted of mostly male civilians, but also a significant number of women, elderly and children. Remains of victims are being uncovered in mass graves by expert teams since 1996. The mass graves included various sites spread across the territory that became known as Republika Srpska after the war ended. In many cases ravines, rivers and lakebeds were used as mass graves where the bodies were dumped and hidden. This article describes the largest operation to uncover human remains of victims in BiH and beyond, which took place in 2010, and was undertaken by the Missing Persons Institute of BiH on the dried up surface of the Peru?ac Lake on the Drina River in Eastern Bosnia. This article aims to record the important aspects of the operation and the personal stories of the victims found.
