The necessity of using the most accurate forecasts for the inflation rate is required by the realisation of economic criteria for the accession to the eurozone and by the inflation targeting strategy of the National Bank of Romania. Considering the assumption that simple econometric models provide better forecasts than complex models, in this paper we combined various forecasts from individual models using as prior information the expectations of experts. The empirical findings for Romanian inflation rate forecasts over the horizon of 2016-2018 indicated that a fixed effects model performed better than other simple models (autoregressive moving average model, dynamic model, simple and multiple linear model, VAR, Bayesian VAR, simultaneous equations model). The Bayesian combined forecasts that used experts’ predictions as priors, with a shrinkage parameter tending to infinity, improved the accuracy of all predictions using individual models, outperforming also naive forecasts and zero and equal weights forecasts. However, predictions based on Monte Carlo simulation outperformed all the scenarios in terms of the mean error and mean absolute error.","PeriodicalId":290683,"journal":{"name":"Research Papers in Economics and Finance","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128390483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology used in the study is based on the analysis of the literature and conclusions drawn from a survey conducted in Poland, the Czech Republic and Hungary (a total sample of 450 units). Logistic regression and the k-means method were used in the statistical analysis. They allow measuring the relationship between the strength of a stimulus represented by the percentage of cases showing a specific response on how productivity is verified by the stimulus. Moreover, they bring the possibility to group factors in clusters representing workers with different sets of productivity factors. Results show that across the study sample, high stress, low employee control, and limited communication with managers minimise the growth of remote work productivity, since social relationships at work are correlated with productivity. Nonetheless, work organisation traits such as proper work environment, travel cost savings, technical assistance access, and a fast Internet connection remain positively related to remote work productivity.","PeriodicalId":290683,"journal":{"name":"Research Papers in Economics and Finance","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114344078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the article is to analyse selected examples of redefinition of the concept of good in the context of new social narratives and the grounding of certain beliefs related to the idea of degrowth and sharing economy. The article is theoretical and references to contemporary research on cultural philosophy and social analyses of economic practice. A socio-regulatory concept of culture was adopted as a research perspective, and humanistic interpretation was used as an explanatory procedure. Qualitative data was analysed using atlas.ti, concept driven coding was used, and content analysis was limited to concept analysis and the creation of conceptual maps. The research results are supposed to show: 1. the impact of modern forms of economic practices using the Internet and IT technology on the redefinition of good, 2. how this redefinition builds the axiological background of society of collaborative consumption.","PeriodicalId":290683,"journal":{"name":"Research Papers in Economics and Finance","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130513225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Still, it continues to pose significant challenges. One such challenge is the problem of system characteristics of MSc methodology at the highest level of scientific practice, i.e. praxeology and systems theory. There are also the problems of MSc synthesis, i.e. the definition of its universal scope, in the light of its increasing diversity and specialisation of doma-ins. This paper aims to elaborate on the achievements to date in management science on the grounds of the systemic-pra-xeological approach, scientific synthesis of methodology, with a particular focus on the role of reasoning and inference. My assertion is that methodology is a subsystem of the core of primary scientific activity of MSc, comprising the com-ponents of scientific practice focused around the scientific method (methods). Its objective domain extends beyond the cognitive function (C), also encompassing value assignment (A), determination of post-diagnosis scientific action (R), deci-sions about scientific models (N) and implementation of scientific models (I) –CARNI system. The scientific methodology of MSc is specifically a product of scientific problems as well as the goals, principles and methods used to solve them, for-ming an exceedingly complex system. Scientific reasoning and inference are not stand-alone scientific methods – they are ingredients of every scientific method. What sets the scientific method apart is the capability of a given scientific manner to solve a given scientific problem.","PeriodicalId":290683,"journal":{"name":"Research Papers in Economics and Finance","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125101102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
