    Opis:
    Sharing economy is cooperation and sharing based on providing the opportunity to access goods and services to those, who precisely need such a service. This paper attempts to organise the yet unsettled areas of sharing economy that today determine its risk and make it ambiguous, unequal, unfair and objectionable in the eyes of many a business environments. The aim of this article is to analyze the risk associated with sharing economy. To fulfil this aim the author has discussed: the paradigm of consumption and the common good in the context of the economy of the future, the etymology of the term of sharing economy and identification of risk that is linked with this phenomenon. The studies were divided into two parts:  the first concerns theoretical risk analysis of the functioning of sharing economy based on subject literature; the second part is a practical analysis of the risk of the impact of sharing economy on the Polish labour market on the example of UBER application. The following research hypothesis was adopted in the paper: The risk of impact of sharing economy on the labour market in Poland is of little significance. The analysis allowed to identify the following risk types in the number of twenty, which are present today in sharing economy: Unequivocal and coherent concept, Data safety, Taxes, Law regulations, Quality, Service performance guarantee, Pursuing claims, Employees rights, Responsibility for clients, Grey market, Competitiveness, Relations: sharing - business, Licences and permissions, Employment relationship, Deflation, Consumer rights protection, Employment, Abuse, Mentality, Sales. A risk analysis of the effects of sharing economy on the Polish labour market showed that this phenomenon was of low significance in the analysed period.

    Opis:
    The traditional methods of risk quantification include a sensitivity analysis, a scenario analysis and a historical simulation. The true nature of risk factors changes is ignored in the traditional ‘ceteris paribus’ approach to a sensitivity analysis, hence it can be reflected in a scenario analysis and a historical simulation. The most significant disadvantage of a scenario analysis is the limited number of scenarios, whereas a historical simulation depends on historical data availability and adequacy. The Monte Carlo simulation is a clear answer to the limitations of traditional methods. The changes of risk factors reflected in the Monte Carlo simulation are simultaneous, non-linear and interdependent. The most important aspect of this method is the stage of taking up the assumptions. The purpose of the paper is to indicate that considering several reasonable sets of assumptions for the Monte Carlo simulation simultaneously can bring even more comprehensive information about enterprise risk.

    Opis:
    Systematic analysis based on the assumption of rational behaviour of human being in addition to the mathematical models is based on the inherent factors in quantification of global risks. Decisions are made based on all available information, to act in order to maximize the utility. However, the current state of global quantification of risks based on the probability of economic loss scenarios, rationality of action in emergencies excludes and puts to the forefront scenarios likelihood and severity based on information asymmetry. If all risk takers were fully informed, it would avoid the moral hazard and the amount of individual risks would be stable in the global context.

    Opis:
    The development of scientific research has led to the very dynamic growth of methods in the area of financial risk management. This refers particularly to risk measures in which quantitative methods are applied. The paper provides a discussion on a systematization of different risk measures proposed in scientific literature and used in practice. There are four criteria proposed in the paper. The first is the concept of risk applied by distinguishing negative and neutral concept. The second criterion is the character of the risk variable, either discrete or continuous . The third criterion makes the distinction between high frequency, low severity events, corresponding to standard (normal) type of risk, and low frequency, high severity events, corresponding to extreme risk. Finally the fourth criterion distinguishes between the risk variable expressed in monetary values and risk variable expressed in time units. Using these criteria the most common groups of risk measures are discussed. The final part of the paper gives a synthetic discussion on model risk which is a risk resulting from the erratic model used in a real world. In the paper three main sources of model risk are presented and the methods to evaluate model risk are given.

    Opis:
    W artykule wykorzystano metody analizy przeżycia (analizy historii zdarzeń do badania czasu pracy u ostatniego pracodawcy osób długotrwale bezrobotnych. W pierwszym posłużono się analizą Kaplana-Meiera w celu identyfikacji oraz efektywnej kategoryzacji zmiennych determinujących długość okresu ostatniej pracy. W drugim kroku skonstruowano model proporcjonalnego hazardu Coxa. Przy konstrukcji modelu wykorzystano następujące kryteria: test istotności modelu oparty na ilorazie wiarygodności oraz kryteria informacyjne. Szczególną uwagę poświęcono własnościom modelu Coxa w celu zapewnienia poprawności jego stosowania w zagadnieniach społeczno-ekonomicznych.
