Deliberation favours social efficiency by making people disregard their relative shares: evidence from USA and India

2017

Groups make decisions on both the production and the distribution of resources. These decisions typically involve a tension between increasing the total level of group resources (i.e. social efficiency) and distributing these resources among group members (i.e. individuals' relative shares). This is the case because the redistribution process may destroy part of the resources, thus resulting in socially inefficient allocations. Here we apply a dual-process approach to understand the cognitive underpinnings of this fundamental tension. We conducted a set of experiments to examine the extent to which different allocation decisions respond to intuition or deliberation. In a newly developed app…

The increase in the prevalence of obesity worldwide has led to great interest in the economic consequences of obesity, but valid and powerful instruments for obesity, which are needed to estimate its causal effects, are rare. This paper contributes to the literature by using a novel instrument: genetic risk score, which reflects the predisposition to higher body mass index across many genetic loci. We estimate IV models of the effect of BMI on labor market outcomes using Finnish data that have many strengths: genetic information, measured body mass index, and administrative earnings records that are free of the problems associated with nonresponse, self-reporting error or top-coding. The fi…

Modélisation du comportement des agriculteurs face au risque dans un modèle de programmation mathématique positive (PMP) à grande échelle

2017

Agricultural production is characterized for being a risky business due to weather variability, market instability, plant diseases as well as climate change and political economy uncertainty. The modelling of risk at farm level is not new, however, the inclusion of risk in Positive Mathematical Programming (PMP) models is particularly challenging. Most of the few existing PMP-risk approaches have been conducted at farm-type level and for a very limited and specific sample of farms. This implies that the modelling of risk and uncertainty at individual farm level and in a large scale system is still a challenging task. The aim of this paper is to formulate, estimate and test a robust methodol…

Information nutritionnelle, choix et caractéristiques des consommateurs

2012

Consumers’ food decisions are based on the information they receive and on their own individual characteristics. This paper is based on an experiment using experimental economics and sensory evaluation to measure individual characteristics of participants and to analyze the impact of nutritional information relative to orange juice. The aim is to explore the potential link between specific characteristics (risk aversion, time preference) and the reactions of consumers to nutritional information. The results show that participants react significantly to this information supplied, positively for the pure orange juice and a negatively for orange nectars. In addition, “risk averse” individuals …

The many faces of human sociality: uncovering the distribution and stability of social preferences

2018

There is vast heterogeneity in the human willingness to weigh others' interests in decision making. This heterogeneity concerns the motivational intricacies as well as the strength of other-regarding behaviors, and raises the question how one can parsimoniously model and characterize heterogeneity across several dimensions of social preferences while still being able to predict behavior over time and across situations. We tackle this task with an experiment and a structural model of preferences that allows us to simultaneously estimate outcome-based and reciprocity-based social preferences. We find that non-selfish preferences are the rule rather than the exception. Neither at the level of …

The Covid-19 containment effects of public health measures:A spatial difference-in-differences approach

2021

Abstract The paper studies the containment effects of public health measures to curb the spread of Covid‐19 during the first wave of the pandemic in spring 2020 in Germany. To identify the effects of six compound sets of public health measures, we employ a spatial difference‐in‐differences approach. We find that contact restrictions, mandatory wearing of face masks and closure of schools substantially contributed to flattening the infection curve. The significance of the impact of restaurant closure does not prove to be robust. No incremental effect is evidenced for closure of establishments and the shutdown of nonessential retail stores.

Le prix des paysages périurbains

2007

L'évaluation économique du prix des paysages périurbains utilise des analyses géographiques (occupation des sols, composition paysagère, distance à des biens paysagers, paysages vus : champ de vision, objets, formes). L'article fait le point sur la littérature en matière de méthode et de résultats et présente l'estimation du prix d'attributs paysagers dans la ceinture périurbaine de Dijon.

Devil in disguise : does drinking lead to a disability pension?

2016

Abstract Objectives To examine whether alcohol consumption in adulthood is related to the incidence of receiving a disability pension later in life. Methods Twin data for Finnish men and women born before 1958 were matched to register-based individual information on disability pensions. Twin differences were used to eliminate both shared environmental and genetic factors. The quantity of alcohol consumption was measured as the weekly average consumption using self-reported data from three surveys (1975, 1981 and 1990). The disability pension data were evaluated from 1990–2004. Results The models that account for shared environmental and genetic factors reveal that heavy drinkers are signifi…

Large scale and information effects on cooperation in public good games

2019

AbstractThe problem of public good provision is central in economics and touches upon many challenging societal issues, ranging from climate change mitigation to vaccination schemes. However, results which are supposed to be applied to a societal scale have only been obtained with small groups of people, with a maximum group size of 100 being reported in the literature. This work takes this research to a new level by carrying out and analysing experiments on public good games with up to 1000 simultaneous players. The experiments are carried out via an online protocol involving daily decisions for extended periods. Our results show that within those limits, participants’ behaviour and collec…

Childhood Physical Activity and Adulthood Earnings

2016

Purpose: This study examined the associations between childhood physical activity level and adulthood earnings. Methods: The data were drawn from the ongoing longitudinal Young Finns Study, which was combined with register-based Finnish Longitudinal Employer–Employee Data and registerbased parents_ background information from the Longitudinal Population Census of Statistics Finland. The study consisted of children who were 9 yr (n = 1257, 52% boys), 12 yr (n = 1662, 51% boys), and 15 yr (n = 1969, 49% boys) of age at the time when physical activity was measured. The children were followed until 2010, when they were between 33 and 45 yr old. Leisure-time physical activity in childhood was se…
