How much can we trust maternal ratings of early child development in disadvantaged samples?

An increasing number of panel studies use short screening questionnaires to assess infant development. Although some research examines the validity of screening questionnaires for middle-class families, knowledge about their accuracy in disadvantaged households is scarce. This paper validates a short screening questionnaire included in the German Socio-Economic Panel (SOEP) with the Bayley Scales of ...

Estimating Heterogeneous Returns to Education in Germany via Conditional Heteroskedasticity

In this paper I investigate the causal returns to education for different educational groups in Germany by employing a new method by Klein and Vella (2010) that bases identification on the presence of conditional heteroskedasticity. Compared to IV methods, key advantages of this approach are unbiased estimates in the absence of instruments and parameter interpretation that is not bounded to local average ...

Atypical Employment and Health: A Meta-Analysis

In this meta-analysis we provide new quantitative evidence on the relationship between the characteristics of working contracts and worker's health. We examine 52 studies covering 26 countries in the time period 1984 - 2010 with a combined sample size of 192. We apply a random effects model using odds ratios and their 95\% confidence intervals as measures for the effect size. We distinguish between ...

Understanding Trust

The World Values Survey (WVS) question on trust has been widely used to study the economic effect of trust. Recent work, however, questions its validity as an accurate measure of trust by showing that it is not correlated with the sender's behaviour in the Berg et al. trust game. What measure then should we trust to measure trust? In this article, we argue that the sender's behaviour in a ...

The Role of Prescribing Generic (Non-proprietary) Drugs in the Prevalence of Therapeutic Inertia in Multiple Sclerosis Care

Importance: Generics companies may market products at low or similar costs to brand drug competitors given the more flexible compliance rules, and regulations for marketing their products in the health system. This phenomenon may influence prescriber’s behavior. Objectives: To compare the prevalence of therapeutic inertia (TI) between primary prescription of brand-name vs. generic drugs in the management ...

Decision making under uncertainty, therapeutic inertia, and physicians’ risk preferences in the management of multiple sclerosis (DIScUTIR MS)

Background: The management of multiple sclerosis (MS) is rapidly changing by the introduction of new and more effective disease-modifying agents. The importance of risk stratification was confirmed by results on disease progression predicted by different risk score systems. Despite these advances, we know very little about medical decisions under uncertainty in the management of MS. The goal of this ...

The Relationship Between Income and Satisfaction: The Effect of Measurement Error and Suppressor Variables

Individual differences in implicit learning abilities and impulsive behavior in the context of Internet addiction and Internet Gaming Disorder under the consideration of gender

Introduction In three consecutive studies, we aimed to investigate the relationship between problematic Internet use (PIU), Internet Gaming Disorder (IGD) and implicit learning abilities, and impulsivity/risk-taking among online video gamers and control participants. Methods In study 1, male visitors, recruited at the “Gamescom” in Cologne (2013), filled in a short version of the Internet Addiction ...
