This study paper investigates the relation between women and men's life stages in Denmark, and their time allocation in paid work, household work, childcare, and leisure time, and, in particular, how this allocation changes when moving from one stage to another stage. The study uses a new Danish panel dataset merged with Danish administrative register data, which allows for analyzing the impact of individual endogenous characteristics of the respondents, such as preferences for doing specific activities. It has been found that the labor supply of fathers of preschool children is not different from that of young men without children, while there is a negative correlation between mothers of preschool children and young women's labor supply. In comparing fathers and mothers of school children with those of preschool children, the study finds a positive correlation in both genders' labor supply. However, fixed effects estimations do not result in a reduction in mothers, nor in fathers, to preschool children's labor supply, indicating that there are some inborn characteristics for the other life-stage changes, which are not revealed by doing ordinary cross-sectional analyses.

In parallel with the recent trend towards conducting ever more surveys, there has also been a decline in response rates, making it harder to obtain the desired number of completed interviews for these surveys. Incentives used in surveys, with the aim of increasing the response rates are manifold, varying from sending letters in advance and an increasing the number of reminder calls to pre-interview payments, cash incentives, charitable donations, and the chance to win lottery prizes. This book examines the impact of incentives and methods used to increase survey response rates.

This study paper examines parental influence on school children's everyday activities that are related to a healthy or an unhealthy lifestyle. The paper is using the Danish Time-Use and Consumption Survey (DTUC) from 2008/2009 with information on fathers', mothers', and children's time use.
