The association between children’s TV consumption and their development is subject of
controversial scientific and public debate. Heavy TV consumption may be detrimental to
children as flashing lights, quick edits and scene changes are overstimulating to
developing brains. It may also involve less time children spent on more stimulating
activities and interactions with their parents. In the present analysis, we use data from
the 2004/5 birth cohort of the Growing Up in Scotland study and investigate the
relationship between weekly hours of TV consumption – measured at the ages 2 to 4 and
cumulatively – and children’s language, cognitive and behavioral outcomes at age 5. Our
analysis shows a gap in TV consumption by parental education that grows across early
childhood. However, we did not find any substantive association between TV consumption
and children’s inductive reasoning and expressive language ability. There were small
associations between TV consumption and conduct problems and prosocial behavior,
particularly for children with lower educated parents. Nonetheless, these results suggest
that the impact of TV consumption on children’s development is less pronounced than
often assumed.

Diversity in education systems, and broader political and economic conditions, are commonly credited with international variations in inequality of educational opportunity (IEO). Comparing East and West Germany before reunification allows us to investigate whether vastly different political, economic and educational systems led to differences in IEO. Post-reunification, East Germany adopted the West’s systems and experienced an economic recession. IEO had been smaller in East than in West Germany but was on an upward trajectory before reunification. After 1990, IEO in East Germany converged to the West German level as a result of decreased IEO in the West and increasing levels in the East. Post-reunification convergence suggests differences in political context and education policy are crucial for IEO.

Mechanisms for the Effect of Field of Study on the Transition from Higher Education to Work

MZES Working Paper 130

Several studies indicate a substantial impact of horizontal differentiations in higher education on
monetary and non-pecuniary labour market outcomes. This paper scrutinizes the underlying mechanisms
of this effect and addresses the question of why fields of study differ in early labour market returns.
According to the training costs model the field of study indicates different amounts of training
costs to employers. The higher the training costs, the more problematic the labour market integration
of graduates. The average expected training costs of a study program are determined by the level of
occupational specificity and the selective choice of the graduates. Specifically, ‘soft fields’ such as
humanities or social sciences are considered as less occupational specific and less academically challenging.
Besides, it is suggested that structural relations between fields and occupational characteristics
act as mediators for the effect of field of study on labour market returns. Using the German HIS
(Hochschul-Informations-System) Graduate Panel 1997 the results show that a lack of occupational
specificity is partly responsible for difficulties in labour market entry of graduates from ‘soft fields’,
whereas selectivity measures do not contribute to an explanation. By contrast, the type of final degree,
the public sector and the required expertise of a job strongly mediate field of study differences. This
emphasizes the substantial role of structural and institutionalized relations between education and the
labour market.
