This study assesses the association between different absenteeism-related factors and the economic costs related to it in a Belgian hospital from 2014 to 2016. During this time 1,692 unique employees worked in this hospital who cost the employer in total 2,071,000.75 euro in terms of direct absenteeism costs. After reviewing the literature about the determinants of absenteeism and the costs and gains related to it, a descriptive analysis is done to show general tendencies and correlations between the variables. It follows an econometric analysis in which multivariate regression models are used to detect the association between the variables. The direct absenteeism costs are regressed on the following factors: gender, age, health status, statute, past absenteeism behavior, seniority, weather conditions, number of legal holidays and the number of influenza incidences in Belgium. Several regression methods are used which give different results

Les institutions de microfinance sont des organisations qui fournissent des services financiers aux personnes pauvres ou exclues du système financier. Cependant, elles sont souvent confrontées à de nombreuses difficultés, comme le non-remboursement des prêts par les emprunteurs. Au Burkina Faso, cette situation a conduit à la faillite de plusieurs institutions de microcrédit. L'objectif de cette étude est d'examiner les facteurs qui affectent la défaillance des emprunteurs en utilisant une régression logistique à l’aide du lasso d’une part et du réseau neuronal artificiel d’autre part. L’étude a porté sur un échantillon de 18 240 prêts accordés dont 1 782 n'ont pas été remboursés. Les variables utilisées dans cette étude regroupent le profil sociodémographique des clients, les caractéristiques des prêts et de leurs entreprises. Les résultats ont montré l'importance des du nombre de prêts antérieurs non soldés, de l'âge et de la durée du prêt dans l’explication des défauts de remboursement. Dans l'ensemble, le modèle de réseau neuronal et celui de la régression logistique donnent des résultats similaires.

This study aimed to determine how excess mortality rates due to the Covid-19 pandemic have changed in high- and middle-income countries. It is examined that the partial relationship between the excess mortality rate and its economical and political factors. Several variables are controlled when the economical and political factors are observed. The sample occurs with the annual excess mortality rates in 99 countries (63 high-income and 36 middle-income economies) between April 2020 and April 2021. The period began when the mainland officially announced an all-cause mortality rate of 10. Two different models are examined with the Weighted Least Squares (WLS) Estimation Method. As a result, it is found that the interest variable, GDP per capita PPP, has a significant effect on the dependent variable, excess mortality rate p - score. While mobility trends for grocery and pharmacy stores, Government Stringency Index, Hospital beds rate, Population age ratio (+65 age), and Young age dependency ratio are statistically significant in one of the Models, they are insignificant in the other Model. On the other hand, there is no significant effect of the urban population, income support, and mobility trends for retail and recreation areas on the excess mortality rate. Geographical location, as continental dummies, is significant only with reference continents, Asia, and North America.
