Does studying abroad enhance employability?

Over 200,000 European students study abroad under the Erasmus programme. It appears that studying abroad may impart skills which are helpful for professional careers after graduation. Approximately, 54% of European students report that participation in the Erasmus exchange programme helped them to obtain a first job; however, interestingly, those from Central and Eastern European countries report it much more often—in 73% of cases. The aim of this paper is to find out whether studying abroad enhances the employability of higher education graduates in Poland. Using the propensity score matching method and data from a nationwide tracer survey of Polish graduates, we find that Polish students who completed at least one semester of their studies abroad do not benefit in terms of a higher employment rate after graduation.     

Application of collective knowledge diffusion in a social network environment

ABSTRACT

We present a group dynamics model that shows knowledge integration as a process occurring over time. As each individual in the group contact others, his own knowledge changes, and over time the collective knowledge is obtained. This allows modeling knowledge diffusion in a social network and while the models presented in this paper are not competitive in that area, they approach the problem from previously unconsidered direction. We test the behavior of the model in a multi-agent simulation and we test a simple advertisement campaign in a social network. We provide discussion of elements needed for making model more competitive.     

Knowledge integration via the fusion of the data models used in automotive production systems

ABSTRACT

In this paper a novel information model that can be used in Manufacturing Execution Systems is presented. The model is based on the fusion of ISA95, AML and OPC UA. ISA95 is used to define, unify and describe the details of a product and production technology. It also enables communication with ERP systems. The AML standard allows information about the production facilities to be presented. The OPC UA address space represents different parts of an information model while the OPC communication protocol enables it to be linked to actual production systems. The proposed concept is illustrated using an actual example of a production line for electronic devices.     

Problems of Incentives for Employees in the Quality Management of the Service Sector

The paper presented below concentrate on worker’s motivation problems in quality management of the services sector. The problem with motivation is particularly important in management of services. In our publication, we analyze motivation system in McDonald’s restaurants form quality of services point of view.     

Urban Geographies of Hesitant Transition: Tracing Socioeconomic Segregation in Post‐Ceauşescu Bucharest

Scholars have raised concerns about the social costs of the transition from state socialism to capitalism in Central and Eastern Europe, and geographers are particularly interested in the spatial expressions and implications of these costs, including apparently increasing residential segregation. Applying a range of segregation measures to 1992 and 2002 census data, this contribution studies socio‐occupational residential segregation in Bucharest. The conclusion is that Bucharest was relatively socio‐spatially mixed at both times; in fact, a modest, yet fully legible, decreasing overall trend is observable. This is at odds with many popular assumptions of the past 20 years.     

The Oaxaca–Blinder Unexplained Component as a Treatment Effects Estimator

In this paper I use the National Supported Work (NSW) data to examine the finite‐sample performance of the Oaxaca–Blinder unexplained component as an estimator of the population average treatment effect on the treated (PATT). Precisely, I follow sample and variable selections from Dehejia and Wahba (1999), and conclude that Oaxaca–Blinder performs better than any of the estimators in this influential paper, provided that overlap is imposed. As a robustness check, I consider alternative sample (Smith and Todd, 2005) and variable (Abadie and Imbens, 2011) selections, and present a simulation study which is also based on the NSW data.     

Working capital (mis)management – impact of executive age

Several recent studies have used the upper echelons theory to explain the impact of personal traits of top executives on various corporate policies. In this, first of its kind, study we find that older executives invest more in working capital; take longer to convert inventories to cash; and pay their suppliers sooner. These findings are consistent with the argument that risk aversion increases with executive age. Our findings indicate that executive age has significant bearing on working capital management policies. This study also initiates new avenues in research relating behavioral aspect of executives with short‐term financial management.     

The Small Border Traffic Zone between Poland and Kaliningrad Region (Russia): The Impact of a Local Visa-Free Border Regime

After Poland’s accession to the EU, the Polish-Russian border became the EU external border. This significantly changed its nature and started the new type of cross border relation. Since 2012, when the Small Border Traffic (SBT) zone came into force, the border has changed its blockade function and started instead to be treated as a resource. The fundamental loosening of the border crossing regime reduced the social and functional distance between Poland and Kaliningrad, and in a broader sense between EU and Kaliningrad. This paper will try to show how small but meaningful initiative, the SBT, has had an impact on cross-border region. The present paper will describe the relationship between larger geopolitical actors and how they affect local border relations. The aim of this paper is to present phenomenon of new visa regime at the Polish-Russian border. The paper likewise describes the impact of the SBT on local communities and their economies, as well as national relations between adjacent countries. The analysis is based on the interviews and surveys conducted in the Polish-Russian border region in late 2014.     

Can banks default overnight? Modelling endogenous contagion on the O/N interbank market

We propose a new model of the liquidity-driven banking system focusing on overnight interbank loans. This significant branch of the interbank market is commonly neglected in the banking system modelling and systemic risk analysis. We construct a model where banks are allowed to use both the interbank and the securities markets to manage their liquidity demand and supply as driven by prudential requirements in a volatile environment. The network of interbank loans is dynamic and simulated every day. We show how the intrasystem cash fluctuations alone, without any external shocks, may lead to systemic defaults, and what may be a symptom of the self-organized criticality of the system. We also analyze the impact of different prudential regulations and market conditions on the interbank market resilience. We confirm that the central bank’s asset purchase programmes, limiting the declines in government bond prices, can successfully stabilize banks’ liquidity demands. The model can be used to analyze the interbank market impact of macroprudential tools.
