Decreasing Sports Activity With Increasing Age? Findings From a 20-year Longitudinal and Cohort Sequence Analysis

According to cross-sectional studies in sport science literature, decreasing sports activity with increasing age is generally assumed. In this paper, the validity of this assumption is checked by applying more effective methods of analysis, such as longitudinal and cohort sequence analyses. With the help of 20 years' worth of data records,from the German Socio-Economic Panel, the development of ...

Testing Missing at Random Using Instrumental Variables

This article proposes a test for missing at random (MAR). The MAR assumption is shown to be testable given instrumental variables which are independent of response given potential outcomes. A nonparametric testing procedure based on integrated squared distance is proposed. The statistic?s asymptotic distribution under the MAR hypothesis is derived. In particular, our results can be applied to testing ...

Is there a "dead-anyway" effect in willingness to pay for risk reduction?

In a recent paper, Pratt and Zeckhauser (JPE, 1996) discuss the measure of individuals' willingness to pay (WTP) for the reduction of risks to their lives which should be used for public decisions on risk-reducing projects. They suggest to correct observed WTP for the "dead-anyway" effect, which says that WTP increases with the level of risk to which the individual is exposed - an effect ...

Feature Selection Methods for Optimal Design of Studies for Developmental Inquiry

Objectives: As diary, panel, and experience sampling methods become easier to implement, studies of development and aging are adopting more and more intensive study designs. However, if too many measures are included in such designs, interruptions for measurement may constitute a significant burden for participants. We propose the use of feature selection—a data-driven machine learning process—in study ...

Income Distribution and Current Account Imbalances

We develop a three-country, stock-flow consistent macroeconomic model to study the effects of changes in both personal and functional income distribution on national current account balances. Each country has a household sector and a non-household (corporate) sector. The household sector is divided into income deciles, and consumer demand is characterized by upward-looking status comparisons following ...

Youth unemployment: Déjà vu?

This paper reviews current issues in youth labour markets in developed countries. It argues that young people aged 16-25 have been particularly hard hit during the current recession. Using the USA and UK as cast studies, it analyses both causes and effects of youth unemployment using micro-data. It argues that there is convincing evidence that the young are particularly susceptible to the negative ...
