<abstract xmlns="http://www.w3.org/1999/xhtml">In the present study, generalized classes of estimators for estimating population mean, ratio and product of two population means using rank of auxiliary character in presence of non-response are proposed. The bias and mean square error of proposed classes of estimators are obtained and their performances examined. Specific conditions under which the members of proposed classes of estimators attain minimum mean square error are obtained. Comparative study of the proposed classes of estimators with the relevant estimators is carried out. An empirical study is given to justify the efficiency of the proposed classes of estimators.</abstract>

Generalized Classes of Estimators for Population Mean, Ratio and Product Using Rank of Auxiliary Character Under Double Sampling the Non-Respondents

<abstract xmlns="http://www.w3.org/1999/xhtml">Identifying the macro-economic determinants of poverty is a key concern for developing poverty reduction policies. Since young people and young migrants in particular are more exposed to poverty, establishing the factors that trigger poverty among these social categories has even more relevance. A preliminary analysis shows that significant differences exist between at-risk-of poverty or social exclusion rate of young migrants and young nationals across European countries. For a more thorough study of the reasons behind these differences in poverty rates between young migrants and young nationals, two panel data regression models are estimated on a cross-section of 23 countries over the period 2010 – 2018 (one model for young migrants, the other for young nationals). Results confirm the main theories in the specialty literature: unemployment and inequality (measured by the Gini index) are the main triggers of poverty or social exclusion both for young nationals and young migrants. However, the income is significant for reducing poverty only for young nationals, but not for the young migrants. This result reinforces the necessity of better integration policies for young migrants in richer Member States.</abstract>

What Triggers Poverty of Young Nationals and Young Migrants? A Comparative Macroeconomic Approach

<abstract xmlns="http://www.w3.org/1999/xhtml">In this research work, rotating savings and credit association (ROSCA) effect on the growth of micro, small and medium enterprises (MSMEs) and identification of a factor supporting the continuity of ROSCAs is studied. A well-designed questionnaire with a reliability value of 0.957 was distributed to 400 entrepreneurs in Wukari through snowball sampling technique. After validity check, 368 valid questionnaires were used for the research. Firstly, a paired t-test was applied to know if entrepreneurs achieve significant positive growth in their business before and after 5 years of joining ROSCAs. At 5% level of significance, entrepreneurs achieved significant positive growth in their businesses 5 years and above of joining ROSCAs. Secondly, a one sample proportion Z-score test was used to identify the major factor responsible for ROSCAs continuity. At 5% significance level, flexibility was identified as the major factor responsible for ROSCAs. It was concluded based on the results obtained that ROSCAs has a significant positive effect on the growth of MSMEs and ROSCAs continuity towards MSMEs growth is due to its flexibility factor in terms of operations, disbursement, seeking loans and interest rate.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Collaborative consumption is currently an exciting topic of interest for many debates and controversies being perceived as a fast-growing social phenomenon. Considering the contemporary development processes via sharing economy, there is an interest to prove that the segment of young consumers practices changed from traditional buying and owning behaviour to collaborative consumption stratagems. Thus, the central objective of the present study is to explore the potential young consumer behaviour adjustments and to discuss the motivations behind those changes by considering the emergence of collaborative consumption.The primary hypothesis of the present article states that intrinsic and extrinsic motivations influence teenager’s attitudes and behavioural intentions regarding participation in collaborative consumption.Regarding the methodology, the author’s performed confirmatory factor analysis and structural equation modelling. The objective was to determine if previously exposed motivational factors influence positively the young consumer’s behavioural intention and their attitude towards a supposed adherence to collaborative consumption schemes.</abstract>

Journal of Social and Economic Statistics

 The Journal of Social and Economic Statistics (JSES) is an electronic open access journal that aims to publish original papers that make interesting and novel contributions to statistical theory and its applications to real life problems.  JSES is a publication of the Department of Statistics and Econometrics of the Bucharest Academy of Economic Studies.  The journal is published two times a year (Summer and Winter issues).  The Journal is indexed in the following databases: EBSCO, RePEc, and ERIHPLUS.  As information is increasingly gaining prominence in today’s globalised society, statistical methods represent a tool of constant interest and usage. There is a multitude of issues which deserve to be studied theoretically and empirically, which are useful for researchers, managers and policy makers alike.  To gain a more comprehensive and deeper understanding on how statistical methods can be conceptualized and understood, the Journal of Social and Economic Statistics aims to present new research on the theory and practice of statistics.  The goal of JSES is to bring together articles which contribute new research ideas in all areas of statistical science, the latest theoretical and applied research in statistics. JSES calls for contributions on how statistical methods can be conceptualized, developed and applied in social and economic practical settings. We welcome empirical papers, especially papers addressing insights from case study research, which can contribute to advancing our knowledge in this important area.  Theoretical, methodological and/or empirical research papers in any sector of the economy and society, qualitative and quantitative studies, as well as conceptual approaches are invited. Suitable topics include but are not limited to:   Theoretical, applied, computational or conceptual papers related to statistics and econometrics  Modelling and simulation  Studies that focus on how statistical methods can be employed to investigate microeconomic, macroeconomic, forecasting, business, and finance related topics  Decision analysis and decision techniques  Research methods   Archiving  Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.
