Time-use, domestic production and public goods in the intra-household decision process: Theoretical, empirical and experimental approaches

这个项目的目的是通过扩展家庭的微观经济理论，采用创新的计量经济学方法来估计更现实的模型，并利用新的调查数据和原始实验的信息，更深入地了解家庭的劳动力供应和消费行为。最近，人们致力于以现实的方式代表家庭，并制定策略来识别个人偏好和家庭每个成员的讨价还价地位。从这个角度来看，集体模式似乎提供了一个方便的环境。然而，现有的研究通常忽略了儿童的存在，将非市场时间同化为纯粹的休闲，并且没有考虑公共转移，这可能导致在衡量家庭内部福利不平等以及估计家庭决策规则参数方面的偏差。因此，我们建议：建立将家庭生产内部化、不参与劳动力市场、私人和公共消费的集体模型，并对家庭中的每个成员进行福利不平等衡量；研究计量经济学方法，这些方法允许在集体框架内考虑复杂的税收优惠系统，并在估计消费选择的决定因素时避免通常强烈的假设，并将这些模型和方法应用于法国、德国、英国和美国的各种数据集；-在实验的基础上测试收入池，以更深入地了解家庭行为的决定因素。在总结研究中，我们将总结法国和德国在该项目中获得的所有结果，并在可能的情况下解释这两个国家在家庭问题上的一些差异。

The purpose of this project is to obtain a deeper understanding of household behavior concerning labor supply and consumption, by extending the micro-economic theory of the household, adapting innovative econometric methods in order to estimate more realistic models, and using information from new survey data and original experiments.Vast efforts have recently been devoted to represent the family in a realistic fashion and develop strategies for the identification of both the individual preferences and the bargaining position of each member of the family. In this perspective, collective models appear to offer a convenient setting. However, the existing studies typically neglect the presence of children, assimilate nonmarket time to pure leisure and do not consider public transfers, potentially leading to bias in the measurement of intra-family welfare inequalities, and in estimates of the parameters of household decision rules.Therefore, we propose to:develop collective models internalizing household production, non-participation in the labor market, private and public consumption, and produce welfare inequality measures accounting for every member in the household;investigate econometric methods which allow considering complex tax-benefit systems in a collective framework, and avoiding the usual strong assumptions when estimating the determinants of the consumption choices, and apply these models and methods to various data sets for France, Germany, the UK and the US;- test for income pooling on the basis of experiments, in order to gain deeper insights into the determinants of household behavior.In a concluding study, we will summarize all results obtained in the project for France and Germany, and, if possible, explain some of the differences between the two countries as regards family issues.
