From Concurrent to Push-To-Web Mixed-Mode: Experimental Design Change in the German Social Cohesion Panel

Research shows that concurrent and sequential self-administered mixed-mode designs both have advantages and disadvantages in terms of panel survey recruitment and maintenance. Since concurrent mixed-mode designs usually achieve higher initial response rates at lower bias than sequential mixed-mode designs, the former may be ideal for panel recruitment. However, concurrent designs produced high share ...

One‐Way Versus Two‐Way Postacquisition Integration Efforts: Theory and Evidence

We develop a theory of postacquisition integration that distinguishes between one-way (acquirer-only) and two-way (mutual) effort strategies. We argue that the method of payment—cash versus shares—may serve as an ex ante commitment mechanism to a particular integration strategy, where cash deals align with unilateral effort, and share deals induce mutual engagement. Using transaction-level mergers ...

Arbeitsmigration im Wandel: Von "Gästen" zu tragenden Säulen

Die Arbeitsmigration nach Deutschland ist ein prägendes Element der wirtschaftlichen und gesellschaftlichen Entwicklung seit den 1950er-Jahren. Während sie anfangs primär als kurzfristige Lösung gegen Arbeitskräftemangel gedacht war, wandelte sich ihr Stellenwert im Laufe der Zeit grundlegend. Heute gilt Einwanderung in den Arbeitsmarkt als unabdingbar, um dem demografischen Wandel und dem Fachkräftemangel ...

How Do My Earnings Compare? Pay Referents and Just Earnings

Comparisons are crucial in shaping evaluations of one’s own position. Following this notion, we investigated the role of historical, financial, partner, occupational, and regional pay referents in predicting the just gross hourly earnings in a representative sample of German workers. Looking at this broad range of pay referents, we find that higher reference earnings were generally associated with ...

Earnings Trajectories After Divorce: The Legacies of the Earner Model During Marriage

Divorce marks the legal endpoint of a marital union. While divorce is increasingly seen as a ‘clean break’, the past marital history of the couple may nevertheless shape their present conditions. In particular, there may be a legacy of a highly gendered division of labour during marriage that may affect the ex-spouses’ earning trajectories beyond the date of divorce. Using register data from the German ...

The Intergenerational Transmission of Risk and Trust Attitudes: Replicating and Extending “Dohmen, Falk, Huffman and Sunde 2012” Using Genetically Informed Twin Data

This replication revisits an influential contribution on the intergenerational transmission of risk and trust attitudes, which, based on data from the German Socioeconomic Panel (GSOEP), reveals a positive correlation between parents' and children's attitudes. The authors of the original study argue that socialization in the family is important in the transmission process. The replication is motivated ...

Gratitude in Fundraising: Do ‘Thank You in Advance’ and Handwritten Thank You Notes Impact Fundraising Success?

While almost all charities rely on a set of donor appreciation strategies, their effectiveness for the success of fundraising campaigns is underresearched. Through two preregistered field studies conducted in collaboration with a leading German opera house (N = 10,000), we explore the significance of expressing gratitude and examine two different approaches to doing so. Our first study investigates ...
