"Facta non verba" : an experiment on pledging and giving
2015
International audience; We design an experiment to investigate whether asking people to state how much they will donate to a charity (i.e., to pledge) increases their actual donation. Individuals’ endowment is either certain or a random variable. We study different types of pledges, namely, private, public and irrevocable, which differ in terms of the cost to the individual for not keeping the promise. We show that in absence of endowment uncertainty, private and public pledges are associated with lower donations as compared to donations in the no-pledge case: private pledges slightly reduce donations and public pledges reduce them more significantly. Donations increase with uncertainty (in…
Market empowerment of the patient: the French experience.
2011
Through analysis of the French experience, this article explores the way economic policy has sought to encourage active, well-informed patients by giving them market power. The new status of the patient as consumer is based on two foundations: the endeavour to build a healthcare market and the activation of demand-based policies. The keystone of this new system is a conception of the market as a process constructed by economic policy. Recent measures such as the standardization of care and the introduction of incentives to respect a treatment pathway then constitute effective levers to establish a free-market rationale.
Environmental expenditure interactions among OECD countries, 1995-2017
2021
International audience; How do countries respond to other countries when setting the level of their environmental expenditures? Using data from 1995-2017 on a sample of 28 OECD countries, we examine the nature and extent of strategic interactions in environmental expenditures among OECD countries using a spatial Durbin model including economic and political control variables and both economic and spatial weight matrices reflecting several interaction mechanisms. The results show the existence of significant positive spatial dependence in environmental spending suggesting that OECD countries consider their neighbors' behavior when making policy choices related to environmental expenditures. …
Dynamics of female labour force participation in France
2013
International audience; This article formulates and estimates a structural intertemporal model of labour force participation. Relying on theoretical characterizations derived from an economic model of lifetime behaviour, we estimate a dynamic probit model with correlated random effects using longitudinal data to allow for a dynamic structure. The model is applied to a panel of married women drawn from the 1997–2002 French Labour Force surveys in order to represent their participation behaviour. It is estimated by maximum simulated likelihood. Our results show that women’s decisions to go out to work are characterized by significant state dependence, unobserved heterogeneity and negative ser…
Determinants of COVID-19 Vaccine Rollouts and Their Effects on Health Outcomes
2022
Background Vaccination against the coronavirus disease (SARS-CoV-2) is understood to be the key way out of the COVID-19 pandemic. Limited evidence exists on the determinants of vaccine rollouts and their health effects at the country level. Objective Examine the determinants of COVID-19 vaccine rollouts and their effects on health outcomes. Methods Ordinary least squares regressions with standard errors clustered at the country level for Cross-section and Panel daily data of vaccinations and various health outcomes (new COVID-19 cases, fatalities, intensive care unit (ICU) admissions) for an unbalanced sample of about 200 countries during the period 16 December 2020 to 20 June 2021. Results…
Putting time into space: the temporal coherence of spatial applications in the housing market
2016
International audience; Relationships between past events, future expectations and present decisions, typically examined through a temporal prism within applied economics, have been lately moving to the spatial dimension through spatial econometrics. However, violations of the “arrow of time”, and thus causality, have been identified in spatial econometric techniques applied to spatio-temporal data consisting of observations each at a specific location and distinct moment in time. A comprehensive review classifies for the first time several redresses to this issue in a currently fragmented literature. This paper puts back the temporal dimension into spatial Hedonic Pricing models through a …
Portrait des étudiants au Togo : état des lieux et analyse des besoins de santé, des comportements de santé et de recours aux soins à partir d’une en…
2021
Parmi les 1,8 milliard de jeunes que l’on dénombre dans le monde, 90 % vivent dans les pays en développement (UNFPA, 2014). Les projections (Nations Unies, 2019a) prévoient une croissance de 62 % de cette population d’ici à 2050 dans les 47 pays les moins développés (dont le Togo fait partie). Au Togo, les jeunes représentent 19,6 % de la population en 2019 (Nations Unies, 2019b).On compte plus de 1,5 million de jeunes âgés de 10 à 24 ans décédés, soit près de 5000 par jour dans le monde (OMS, 2021). La probabilité moyenne à l’échelle mondiale qu’un enfant de 10 ans meure avant l’âge de 24 ans est six fois plus élevée en Afrique subsaharienne que dans le reste du monde (OMS, 2021). Ces chif…
Using cluster analysis to study the modelling abilities of engineering undergraduate students: a case study
2016
In this contribution we discuss the application of a quantitative, non-hierarchical clustering method to make sense of the answers that 120 engineering undergraduates students at the University of Palermo, Italy, gave to four open-ended questions on the meaning of the modeling processes in Science. We will show that the use of non-hierarchical analysis allows us to easily separate students into groups that can be recognized and characterized by common traits in students’ answers without any prior knowledge on the part of the researcher of what form those groups would take (unbiased classification).
Peer-group mentoring as a tool for teacher development
2014
Abstract: Peer-group mentoring (PGM) is a new model designed to support the professional development of teachers in Finland. This study examines the experiences of mentees participating in PGM and potential differences in the experiences of teachers in general education and vocational education. It also addresses the mentees perceptions of the results of PGM with regard to the professional, personal and social dimensions of professional development. Quantitative research methods were used. An online survey was completed by 69 teachers in general education and 47 teachers in vocational education (n = 116). The results showed that the participants saw PGM as an important tool for professional…
Molecular origin and hydration dependence of protein anharmonicity: an elastic neutron scattering study.
2010
Two main onsets of anharmonicity are present in protein dynamics. Neutron scattering on protein hydrated powders revealed a first onset at about 150 K and a second one at about 230 K (the so called dynamical transition). In order to assess the molecular origin of protein anharmonicity, we study different homomeric polypeptides by incoherent elastic neutron scattering, thus disentangling the contribution of different molecular groups in proteins. We show that methyl group rotations are the main contributors to the low temperature onset. Concerning the dynamical transition, we show that it also occurs in absence of side chains; however, the presence and mobility of side chains substantially i…
