The Causal Effect of Watching TV on Material Aspirations: Evidence from the “Valley of the Innocent”

Abstract
The paper addresses the question of whether TV consumption has an impact on material aspirations. We exploit a natural experiment that took place during the period in which Germany was divided. Owing to geographical reasons TV programs from the Federal Republic of Germany could not be received in all parts of the German Democratic Republic. Therefore a natural variation occurred in exposure to West German television. We find robust evidence that watching TV is positively correlated with aspirations. Our identification strategy implies a causal relationship running from TV to aspirations. This conclusion resists various sets of alternative specifications and samples.

The Transition to Post-industrial BMI Values Among US Children

NBER Working Paper No. 13898,
No. 13898,
2008
Abstract
In our opinion, the trend in the BMI values of US children has not been estimated accurately. We use five models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 born 1941-2006 on the basis of all NHES and NHANES data sets. We also use some historical BMI values for comparison. The increase in BMIZ values during the period considered was on average 1.3σ (95% CI: 1.16σ; 1.44σ) among black girls, 0.8σ for black boys, 0.7σ for white boys, and 0.6σ for white girls. This translates into an increase in BMI values of some 5.6, 3.3, 2.4, and 1.5 units respectively. While the increase in BMI values started among the birth cohorts of the 1940s among black females, the rate of increase tended to accelerate among all four groups born in the mid-1950s to early-1960s with the contemporaneous spread of TV viewing. The rate of increase levelled off somewhat thereafter. There is some indication that among black boys and white girls born after c. 1990 adiposity has remained unchanged or perhaps even declined. The affects of the IT revolution of the last two decades of the century is less evident. Some regional evidence leads to the speculation that the spread of automobiles and radios affected the BMI values of boys already in the interwar period. We infer that the incremental weight increases are associated with the labor-saving technological developments of the 20th century which brought about many faceted cultural and nutritional revolutions.

Vergleich der Weiterbildungsaktivitäten von Arbeitslosen und Vollzeiterwerbstätigen
Birgit Schultz, Joachim Wilde
IWH Discussion Papers,
No. 9,
2007
Abstract
Many empirical studies consider either training activities of the unemployed or training activities of the employees in Germany. However, a comprehensive comparison of both groups is missing. The paper closes this gap. Using data of the latest time use survey (Zeitbudgeterhebung) of the Federal Statistical Office, the amount of training is compared for both groups. Furthermore, it is described which types of activities are made use of in particular. Heterogeneity due to different relevant socioeconomic characteristics in the two groups is eliminated by the appliance of a matching procedure. Findings demonstrate that only 49% of the unemployed persons participate in any kind of training activities off the job. In case of the full-time employment 59 % would take part. Concerning the average expenditure of time per week the difference turns around, i.e. the expenditure of time is higher during unemployment. However, a high proportion of the training activities of the unemployed falls upon general training, e.g. by reading books or watching TV. Furthermore, the result is driven by a different potential of time that can be used for training activities off the job. Relating to this potential of time the amount of training activities is still lower during unemployment.

Zeitpotential für berufliche Weiterbildung von Arbeitslosen wenig genutzt
Joachim Wilde, Birgit Schultz

Abstract
In general, unemployed persons spend more time on further training than full-time employees. Using data of the latest time use survey (Zeitbudgeterhebung) of the Federal Statistical Office, this study analyzes whether this higher potential of time is being used or not. Furthermore, it describes which types of activities are made use of in particular. Heterogeneity due to different relevant socioeconomic characteristics in the two groups is eliminated by the appliance of a matching procedure.
Findings demonstrate that only around 15 % of the unemployed persons participate in further training activities off the job. In case of the full-time employment just under 40 % of the persons would take part. Relating to the average expenditure of time per week the difference decrease clearly. However, altogether the expenditure of time is not higher during unemployment.
A selection of subsamples points out different results, i.e. in some subsamples the expenditure of time for further training is larger during unemployment. However, in the subsample of low skilled persons these results are mainly caused by activities like hearing radio or watching TV. Thus, it is doubtful whether the higher expenditure of time qualifies for the primary labour market.
