Our article investigates the impact of vertical integration (without foreclosure) on innovation. We compare cases where either (i) two manufacturers or (ii) a manufacturer and a vertically integrated retailer invest. Then, the independent manufacturer(s) and the retailer bargain over nonlinear contracts before selling to consumers. We show that vertical integration always increases the incentives to ...

While socioeconomic status (SES) and personality have both been identified as relevant predictors of academic achievement, little is known about their possible interplay in predicting school performance. The present study used the latent moderated structural equations (LMS) method to investigate latent interactions between familial SES and parent-rated Big Five in a sample of German high school students ...

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 ...

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 ...

While the existing evidence on added worker effects is mixed, most studies find no or only small effects. However, studies to date have mostly analyzed individuals’ actual labor supply responses to their partners’ job loss, neglecting to consider a potential mismatch between desired and actual labor supply adjustments. Using data from the German Socio-Economic Panel (SOEP), we study individuals’ changes ...

This paper outlines two studies on education bias in German probability-based surveys. Study 1 reviews data from 67 surveys across 19 survey programs conducted in Germany from 2000 to 2023. We found a consistent underrepresentation of individuals with a low level of formal education. We also found that the transition to self-administered modes due to rising survey costs may exacerbate this bias in ...

We examine the additivity of expectations over different time intervals. For example, when asked about 10-year stock price growth, survey respondents report an expected change that is not equal to, but closer to zero than, the sum of their expectations over two shorter time intervals that cover the same 10 years. Such subadditivity, which we also find in expectations for other economic variables, is ...

This paper presents comparative information on the strength of the association between socioeconomic status (SES) and literacy skills at ages 6–8, drawing on data from France, Germany, Japan, Rotterdam (Netherlands), the United Kingdom, and the United States. We investigate whether the strength of the association between SES and literacy skills in early-to-mid childhood depends on the operationalization ...

Recent proposals for a European deposit insurance scheme (EDIS) favor a reinsurance framework. In this paper, we use a regime-switching open economy DSGE model with bank defaults to assess the relative efficiency of such a scheme. We find that reinsurance by EDIS is more effective in stabilizing real activity, credit, and welfare than a national fiscal backstop. We demonstrate that risk-weighted contributions ...

In the fight against antibiotic resistance, reducing antibiotic consumption while preserving healthcare quality presents a critical health policy challenge. We investigate the role of practice styles in patients’ antibiotic intake using exogenous variation in patient-physician assignment. Practice style heterogeneity explains 49% of the differences in overall antibiotic use and 83% of the differences ...
