Currently, no guidelines exist on how to evaluate the performance of health systems fighting the SARS-CoV-2 pandemic. Therefore, this study seeks (1) to develop a conceptual framework that would be helpful in the given context, and (2) to test the feasibility of the proposed approach. The framework is conceptualized based on investigating critical dimensions and indicators for the successful design of a method for evaluating the performance of health systems. Subsequently, the taxonomic measure of development is used and a correlational analysis made in order to run a pilot test of the proposed concept. The finalized conceptual framework has five input dimensions (demographical burden, epidemiological burden, health-related quality of life, financial resources, and access) described by 18 indicators, and two output domains (outcomes, productivity) described by six indicators to monitor system performance under the COVID-19 pandemic. The pilot-test conducted in European Union countries and the United States proved the model to be useful and feasible. The proposed framework can be used to assess the performance of health systems fighting novel pathogens, such as SARS-CoV-2, worldwide. Our methodological approach can be used as a benchmark for international agencies such as the World Health Organization in developing their own frameworks. The paper presents the first research exploring the evaluation of a health system during the COVID-19 pandemic. It has the potential to help monitor a health system’s performance during the pandemic by accounting for specific country-related circumstances. In a broader sense, it can contribute to boosting health market competitiveness in terms of quality.
The aim of the article is the use methods of duration analysis to assess the fluctuations in the prices of shares of companies listed on the Stock Exchange in
The subject of the article is the use of methods of event history analysis to assess the fall of prices and the subsequent increase of share prices of companies operating in the construction industry, developers (real estate) and building materials industry compared to other industries. The 328 examined companies were listed on the continuous market and the parallel market on the Stock Exchange in Warsaw. Share prices were observed in the period from 1 January 2008 to 31 December 2009 which was based on the earlier observations of stock quotes and the WIG index, the latter reaching its minimum in February 2009. The closing price of a share was taken into account. The 60% decrease and 80% growth in shares prices in particular sectors were analysed. What was assessed was the risk of fall in share prices and their chance for recovery. Additionally, the intensity of the increase of share prices and the probability of failure to reach the limit were examined.
The purpose of the article is to present the analysis of the influence of unemployment benefit on the duration of registered unemployment spells. The authors made a hypothesis that the very fact of receiving the benefit extends the job seeking time and determines the intensity of unemployment exit. The power of this influence varies depending on a subgroup the unemployed person belongs to. The study was conducted on the basis of data from the Poviat Labour Office in Sulecin. The data were collected as a part of the European Union project implementation. The analysis covered two periods of time – before and after Poland’s accession to the European Union and the subsequent changes in legal regulations concerning unemployment benefits. The authors observed separate cohorts of the unemployed registered in 2001 and 2005. The closing dates of the observations were: the end of 2003 and 2007, respectively. Also, the authors examined whether the EU projects implemented after 2004 had an effect on the length of the unemployment spells as well as on the intensity of the unemployment exit. The study confirmed the research hypotheses. The fact of claiming the unemployment benefit prolonged the unemployment spells in both periods of observation. The loss of the right to the benefit increased the probability of de-registration in each sub-group.
Research background: Some statistics are of a bilateral nature. This is how foreign trade data is organized. They are recorded both in the supplier and recipient countries, hence they are called mirror data. The data recorded at both trading partner countries are not the same for different reasons. Such differences between data on the same groups of transactions are often referred to as the asymmetry of mirror data. The information about the value of the flows of goods are of great importance in economic analyses and therefore their quality is particularly important. Purpose of the article: The aim of this paper is to present a new measure of data asymmetry ? the aggregated quantity index with value-based weights. Methods: The proposed measure combines the quantity and the value of turn-over in individual trade relations. Such a measure makes it possible to eliminate basic deficiencies in value-based measures, while considering the specificity of trade in individual countries. The proposed measure of data asymmetry was confronted with several measures present in the literature and previously used by the Authors. The numerical example uses Comext data on intra-Community trade in 2017 provided by Eurostat. Findings & Value added: The proposed measure performs better than all the previously used data asymmetry indices. It is to some extent immune to exchange rate differences and inconsistencies resulting from the inclusion of transport and insurance costs in the value of goods. In addition, it gives lower weights to unimportant trade directions than other data asymmetry indices. Since the new index has proved to be better than the measures previously used, it is worth applying to those trade relations where the data are not de-rived from customs documents, but from declarations made by businesses, as in the case of intra-Community trade.
Research background: As a system of official EU statistics, Intrastat contains data collected by Member States aggregated by Eurostat on the Union’s level in the form of COMEXT database. Country-level data are based on declarations made by businesses dispatching or acquiring goods from other EU Member States. Since the same transaction is declared twice — as an ICS in one country and at the same time as an ICA in another country by the partner — the database contains mirror data. Analysis of mirror data lets us assess the quality of public statistics data on international trade. Purpose of the article: The aim of the article is to rank EU Member States according to quality of data on intra-Community trade in goods collected by Intrastat. Foreign trade stimulates economic development on one hand and is the development’s reflection on the other. Thus it is very important that official statistics in this area be of good quality. Analysis of mirror data from partner states in intra-Community trade in goods allows us to claim that not every Member State pro-vides data of satisfactory quality level. Methods: We used the authors’ methodology of assessing quality of mirror data. These include data asymmetry indices, both proposed by Eurostat and the authors’ own proposals. We have also examined the changes in the above mentioned rankings over time. Findings & Value added: The result of the survey is ordering of EU Member States according to the quality of data on intra-Community trade in goods. The rankings are presented for the period of 2014–2017, during which there were 28 Member States of the EU. Changes in distinct countries’ positions were shown as a result of changes in overall quality of statistical data collected in these countries. The research methodology can be used in the process of monitoring data quality of the Intrastat system.
