The effect of teenage employment on character skills, expectationsand occupational choice strategies
(2016) Fuchs, Benjamin
A growing body of research suggests that, even after controlling for cognitive abilities, personality predicts economic success in later life. The learning environment at school focuses on knowledge and cognitive skills. The transmission of character skills, however, is not at the center of attention. Leisure activities as informal learning activities outside of school may affect the formation of skills. By providing valuable opportunities, working part-time while attending full-time secondary schooling can be seen as a stepping stone toward independence and adulthood. The channel of the positive influence, however has not been identified empirically. I suggest that employment during adolescence promotes the formation of character skills that are known to have a positive effect on labor market outcomes and educational achievement. Employing a exible strategy combining propensity score matching and regression techniques to account for self-selection, I find beneficial e ects on character skills. Further, it improves future expectations, the knowledge on which skills and talents school students have and reduces the importance of parents advice with respect to their childs future career. The results are robust to several model specifications and varying samples and robust to including family-fixed effects.
The potential of smartphone apps to collect self-recorded data in agricultural households : a study on time-use in Zambia
(2019) Daum, Thomas; Birner, Regina
Mobile information and communication technologies (ICTs) have spread across the developing world and are used increasingly by smallholder farmers. While the potential of ICTs, such as smartphone applications, to provide new opportunities for agricultural development is widely acknowledged, the potential to use them as research tools has not been explored. This thesis assesses the potential of smartphone applications for the collection of data from agricultural households in developing countries. Can smartphone applications that use visual tools be used for self-recording of data by the respondents themselves where literacy levels are low? Can such smartphone applications that allow for real-time data recording increase the accuracy of the collected data? Answering these questions is important as, so far, data from agricultural households are usually collected using surveys, which are prone to recall biases. This is a problem, as researchers, policymakers and development practitioners need reliable data for their work. Poor data can lead to misguided policy recommendations and actions with adverse effects on vulnerable population groups. This can lead to agricultural development trajectories that are socially unequal and unsustainable. To assess the potential of smartphone apps to collect self-recorded data, a smartphone application called Timetracker was developed as part of this thesis. The Timetracker allows study respondents to record data in real time with the help of illustrations. Recording data in real time reduces recall bias, and using pictures ensures that participants with low literacy can use the application. In its current form, the Timetracker can be used to collect data on time-use and nutrition. Collecting reliable data on time-use and nutrition is key for various strands of research. For example, time-use data are needed to calculate labor productivity and analyze how productivity is affected by new technologies. Time-use data can also help reveal gender-based power relations and asymmetries by pointing out unpaid domestic work. Similarly, nutritional data are crucial for various academic fields and debates. For example, nutritional data are needed to explore the factors determining food and nutrition security, to study how farm diversity affects consumption diversity and to monitor food and nutrition policies and programs. This study is based on three main chapters, which reflect the main objectives of the whole thesis: 1) to explore and test whether smartphone applications can be used to collect data from rural households in developing countries focusing on time-use and nutrition data, 2) to assess the accuracy of data collected with smartphone applications vis-à-vis recall-based data collection methods, and 3) to use the data to understand the effects of agricultural mechanization on the intrahousehold allocation of time-use within smallholder farming households in Zambia. The first two chapters have a primarily methodological focus. The last chapter is an empirical study. This thesis concludes that in addition to improving the accuracy of socioeconomic data collection, smartphone applications may open new research pathways, including through the opportunities provided by real-time data collection and by combining self-recorded data with sensor-recorded data, which may open interesting transdisciplinary research pathways. This thesis suggests that there is a large and still untapped potential for using smartphone applications to collect data on complex agricultural systems in the digital age.
Work time and hours constraints
(2012) Otterbach, Steffen; Sousa-Poza, Alfonso
This thesis aims to draw a comprehensive picture of labor supply hours and the extent and determinants of work hours constraints while pinpointing possible consequences and policy implications of such constraints and highlighting the relevance of individual work time preferences with respect to a meaningful debate on work time issues. Most particularly, it offers a comprehensive analysis of how the consideration of individually preferred work hours and the discrepancy between these and actual work hours can foster an understanding of individual labor market participation decisions. What insights, for example, do individual preferences for work hours provide for successful policy implementation if policy makers address topics such as the length of the work week, balance between work and family life or the need for more substantive part-time jobs? Likewise, what incentives might lead employers to reduce work hour mismatches? Despite their importance, these issues of work hour preferences and constraints have not yet been adequately considered in the overall debate on work time and labor market policy. Nor has attention been paid to a further pivotal question: how these restrictions affect workers´ health and well-being. To date, there are only a few studies that investigate the meaning of work hours constraints in the context of happiness and well-being in the work place. This thesis, therefore, constitutes the first study for Germany and the United Kingdom on the potential adverse health consequences of being constrained in the choice of number of work hours.
