This paper provides the first comprehensive review of the empirical and theoretical literature on the determinants of the elasticity of substitution between capital and labor. Our focus is on the two-input constant elasticity of substitution (CES) production function. By example of the U.S., we highlight the distinctive heterogeneity in empirical estimates of σ at both the aggregate and industrial ...

We analyze competition between Internet Service Providers (ISPs) where consumers demand heterogeneous content within two Quality-of-Service (QoS) regimes, Net Neutrality and Paid Prioritization, and show that paid prioritization increases the static efficiency compared to a neutral network. We also consider paid prioritization intermediated by Content Delivery Networks (CDNs). While the use of CDNs ...

Competence in financial decision making is becoming increasingly important. However, most individuals make suboptimal financial decisions. Project A03 examines the hypothesis that these poor decisions may be (partially) caused by behavioral distortions and we explore how these interact with a person’s level of financial literacy. In particular, the project will test the impact of (i) biased...

Children's development is fostered by both high quality Early Childhood Education and Care (ECEC) settings and high quality home learning environments. As we know little about the interrelations between these two environments, we examine whether the child's attendance in a high quality ECEC arrangement relates to the quality of her home learning environment. Using rich NICHD Study of Early Child Care ...

We empirically investigate the possibility that a decision maker prefers to avoid making a decision and instead delegates it to an external device, e.g., a coin flip. A large data set from the centralized clearinghouse for university admissions in Germany shows a choice pattern of applicants that is consistent with coin flipping and that entails substantial consequences for the matching outcome. In ...

Competitive escalation occurs frequently in managerial environments, when decisions create sunk costs and decision makers compete under time pressure. In a series of experiments using a minimal dollar auction paradigm, we test interventions to prevent competitive escalation. Without any intervention, most people, including experienced managers, escalate and lose money by bidding more than the price ...

DIW Discussion Papers 1785 / 2019
Case and Deaton (2015) document that, since 1998, midlife mortality rates are increasing for white non-Hispanics in the US. This trend is driven by deaths from drug overdoses, suicides, and alcohol-related diseases, termed as deaths of despair, and by the subgroup of low-educated individuals. In contrast, average mortality for middle-aged men and women continued to decrease in several other high-income ...

Fairtrade certification aims at transferring wealth from the consumer to the farmer; however, coffee passes through many hands before reaching final consumers. Bringing together retail, wholesale, and stock market data, this study estimates how much more consumers are paying for Fairtrade-certified coffee in US supermarkets and finds estimates around $1 per lb. I then assess how this price premium ...
