Abstract

After joining the European Union in 2004, the post-communist countries have dramatically changed their structure of expenditure for medical services. The cause of this is legislative and ownership changes in the new economy. The study analyzed the expenditure on medical services in the European Union with a special focus on Poland, Latvia, Lithuania and Estonia. The European Union countries were divided into clusters using different methods, that is, Ward’s, Two Step and Centroid Clustering. In the paper, the structure and changes in health expenses were presented according to the types of expenditures over the years 2004-2015. Countries were assigned to clusters based on three variables: medical products, appliances and equipment, outpatient services and hospital services. Variables were considered as a percentage of household budget. In Lithuania, Latvia and Estonia, there is a clear increase in the outpatient services spending compared to the hospital services expenditure.

Abstract

An assessment of the degree of the development of the digital economy in Poland in comparison to chosen European countries is the main purpose of the paper. The methodology of the conducted research is based on the analysis of secondary sources and applying statistical methods. In order to make the comparison in methodically correct manner, synthetic measures of the development of the e-economy were used in the form of two indexes: NRI (Networked Readiness Index) and DESI (Digital Economy and Society Index). On the basis of available statistical data, four European countries were confronted with Poland. Results of the analysis indicate a relatively unfavorable situation of Poland.

Czech Republic, Denmark, Finland, Norway, and Poland. Secondly, models can be differentiated according to how much the procedure is formalized. In other words, in Denmark, Finland, Flanders (Belgium), Lithuania, Poland and Spain, evaluation is formalized because of some type of publisher classifications and quality labels, or formal criteria for books are formalized and used. In non-formalized systems, like in Serbia, France, Italy, Latvia, Israel, Portugal and Switzerland, evaluation is based on expert panels or committees. Thirdly, the analyzed European models
