Groups put at Particular Risk by COVID 19 (GaPRisk)

The Covid-19 pandemic poses numerous societal challenges. We will examine how it affects distinct social and at-risk groups in Germany, what it implies for societal inequalities, and what role welfare state measures play. First, we will describe the situation of the population before and during the pandemic in the health and the socio-economic domain. In each domain, we will study a set of core...

Risky Asset Holdings during Covid-19 and Their Distributional Impact: Evidence from Germany

We present evidence from a repeated survey on risky asset holdings carried out on a representative sample of the German population six times between April and June 2020. Given the size of the Covid-19 shock, we find little evidence of portfolio rebalancing in April 2020. In May, however, individual investors started buying heavily, fueling market recovery. The cross-section shows large differences ...

Discounting Behavior in Problem Gambling

Problem gamblers discount delayed rewards more rapidly than do non-gambling controls. Understanding this impulsivity is important for developing treatment options. In this article, we seek to make two contributions: First, we ask which of the currently debated economic models of intertemporal choice (exponential versus hyperbolic versus quasi-hyperbolic) provides the best description of gamblers’ discounting ...

Leisure Activities as a Driver of Personality Development? A Random-Intercept Cross-lagged Panel Model across 13 Years in Adulthood

Repeated experiences and activities drive personality development. Leisure activities are among the daily routines that may elicit personality change. Yet despite the important role they play in daily life, little is known about their prospective effects on personality traits and vice versa. The objective of this study was to examine the extent to which within-person changes in leisure activities lead ...

Keine eindeutige Lagerbildung bei Ungleichheitskonflikten – Open-Access-Artikel auf Basis der SOEP-Innovationsstichprobe erhält den ersten Preis der Fritz Thyssen Stiftung

Immer wieder ist in Debatten von einer neuen Lagerbildung die Rede: Demnach sprächen sich zum Beispiel die besser gestellten Gruppen für Migration und die Anerkennung von Diversität aus, während die schlechter gestellten dem ablehnend gegenüberstünden. Auf Basis der SOEP-Innovations-Stichprobe aus dem Jahr 2017 hat nun ein Team von Sozialwissenschaftlern der Humboldt Universität ...

Long-run Expectations of Households

The rational expectations assumption, e.g. in life-cycle models and portfolio-choice models, prescribes that all actions are in line with a well-structured and unbiased system of expectations. In reality, justification and identification of expectations are nontrivial, and we lack empirical evidence especially for the long run. This paper starts to fill this gap and elicits short-run and long-run expectations ...

Urban Green Is More than the Absence of City: Structural and Functional Neural Basis of Urbanicity and Green Space in the Neighbourhood of Older Adults

The relationship between urbanization, the brain, and human mental health is subject to intensive debate in the current scientific literature. Particularly, since mood and anxiety disorders as well as schizophrenia are known to be more frequent in urban compared to rural regions.Here, we investigated the association between cerebral signatures, mental health and land use indicators (Urban Fabric and ...

Kein Grund zu Angst vor Inflation

Wie das Statistische Bundesamt heute mitgeteilt hat, lagen die Verbraucherpreise im Juli 2021 um voraussichtlich 3,8 Prozent über dem Vorjahresmonat - deutlich mehr als im Juni und zum ersten Mal seit Sommer 2008 über der Drei-Prozent-Marke.
