Testing for Asymmetric Information in Insurance Markets: A Multivariate Ordered Regression Approach
2016
The positive correlation (PC) test is the standard procedure used in the empirical literature to detect the existence of asymmetric information in insurance markets. This article describes a new tool to implement an extension of the PC test based on a new family of regression models, the multivariate ordered logit, designed to study how the joint distribution of two or more ordered response variables depends on exogenous covariates. We present an application of our proposed extension of the PC test to the Medigap health insurance market in the United States. Results reveal that the risk–coverage association is not homogeneous across coverage and risk categories, and depends on individual so…
Robot Shift from Industrial Production to Social Reproduction
2015
This chapter analyses people’s attitudes towards the use of robots in the different domains of life and, specifically, in the domain of social reproduction. The analysis is based on Eurobarometer 382 “Public Attitudes towards Robots” data (N = 26,751), which was carried out among EU citizens aged 15 and over in 27 member states in 2012. The results of the study show that on average European perceptions of robots are positive and permissive. The life domains in which robots have already been used for a long time (e.g. space exploration, manufacturing, military and security business, search and rescue work) turn out to be the most popular areas for the further penetration of robots. The least…

Age-related socio-economic and geographic disparities in breast cancer stage at diagnosis: a population-based study.
2015
Background: This study aimed to determine the impact of socio-economic and geographic disparities on disease stage at diagnosis according to age in breast cancer (BC) patients. Secondary purpose was to describe survival . Methods: All women with primary invasive BC, diagnosed from 1998 to 2009 in the department of Cote d’Or were retrospectively selected using data from the Cote d’Or BC registry. European transnational ecological deprivation index (French European Deprivation Index) was used to measure the socio-economic environment. Relationships between socio-geographic deprivation and disease stage at diagnosis according to age were assessed by a multilevel ordered logistic regression mod…
Colorectal cancer stage at diagnosis in migrants versus non-migrants (KoMigra) : study protocol of a cross-sectional study in Germany
2014
Background: In Germany, about 20% of the total population have a migration background. Differences exist between migrants and non-migrants in terms of health care access and utilisation. Colorectal cancer is the second most common malignant tumour in Germany, and incidence, staging and survival chances depend, amongst other things, on ethnicity and lifestyle. The current study investigates whether stage at diagnosis differs between migrants and non-migrants with colorectal cancer in an area of high migration and attempts to identify factors that can explain any differences. Methods/Design: Data on tumour and migration status will be collected for 1,200 consecutive patients that have receive…
Smoking Status and Severity of Ischemic Stroke. A Population-Based Study
2013
We aimed to investigate the impact of smoking status on clinical severity in patients with ischemic stroke event (IS). Patients were prospectively identified among residents of the city of Dijon, France (ca. 151,000 inhabitants), using a population-based registry, between 2006 and 2011. Demographic and clinical data were recorded. The initial clinical severity was quantified by the means of the National Institutes of Health Stroke Scale (NIHSS). Multivariable ordinal logistic regression was used to assess the effect of smoking status on severity. Among the 1,056 recorded patients with IS, data about smoking status were available for 973 (92.1%), of whom 658 (67.3%) were non-smokers, 187 (19…
Increasing early ambulation disability in spontaneous intracerebral hemorrhage survivors
2017
ObjectiveTo evaluate temporal trends in early ambulatory status in patients with spontaneous intracerebral hemorrhage (ICH).MethodsAll patients with ICH between 1985 and 2011 were prospectively registered in a population-based registry in Dijon, France, and included in the study. Outcomes of ICH survivors were assessed at discharge from their stay in an acute care ward with the use of a 4-grade ambulation scale. Time trends in ambulation disability and place of discharge were analyzed in 3 periods (1985–1993, 1994–2002, and 2003–2011). Multivariable ordinal and logistic regression models were applied.ResultsFive hundred thirty-one patients with ICH were registered, of whom 200 (37.7%) died …
Approaches used to care for carious primary molars among pediatric dentists and general dental practitioners in Saudi Arabia
2018
Background The aim of this cross sectional study was (1) to identify and compare the approaches which are used to care for carious primary molars between pediatric dentists (PDs) and general dental practitioners (GDPs) in Saudi Arabia and (2) to evaluate the knowledge level of the most appropriate treatment decisions for both groups with regard to caries in primary molars and its relation with demographic variables. Material and Methods A random sample of 600 GDPs and all registered PDs (n = 100) in the Saudi dental society in 2016 were emailed a two part questionnaire; the first part included questions about demographic data and the second part investigated knowledge of the participants of…
Opening the black box of food quality in the short supply chain: Effects of conventions of quality on consumer choice
2015
In recent years new forms of food distribution organisation, known as short supply chains, have gained ground. The local nature of such distribution has positive effects on the environment and on the local economy. Consumers appear to trust the short supply chain, and it has achieved considerable success. However, the short supply chain has credence characteristics which, by their very nature, cannot be identified through a system of certification. The question we address in this paper is whether it is possible to identify the constituent elements of the credence trait in relation to food quality in the short supply chain. Our hypothesis is that the latter are linked to a range of socially …
Assessment of subjective economic well-being in Italy
2010
Using the European Survey on Income and Living Conditions for the year 2005, we analyze the subjective economic well-being and its determinants relating to some sub-groups of Italian households by means of an Ordered Logit Model (OLM), whose dependent variable is represented by a perception variable, that is the ability of households to make ends meet. The empirical results highlight that the main determinants of subjective economic well-being are the same for the four typologies of households. The subjective economic well-being is not only related to the economic status, but it is mostly influenced by socio-demographic variables, as work and education conditions. Furthermore, the level of …
