Are they playing by the same rules? A consumer gifting classification of marital dyads

This article sets out a research program that examines the dynamics of gifting behavior of long-term committed dyadic relationships—married couples. Our research considers the findings of a study in which the reported gifting behavior of couples reveals two gifting rulebooks; the first rulebook consisting of a set of symbolic communication rules, and a second rulebook consisting of economic exchange rules. Most importantly, we develop a consumer gifting classification of marital dyads. Finally suggestions are offered for future research and implications are drawn for marketing strategy.     

Cost-comparison of two trabecular micro-bypass stents versus selective laser trabeculoplasty or medications only for intraocular pressure control for patients with open-angle glaucoma

Aim: Patients with open-angle glaucoma (OAG) whose intraocular pressure is not adequately controlled by one medication have several treatment options in the US. This analysis evaluated direct costs of unilateral eye treatment with two trabecular micro-bypass stents (two iStents) compared to selective laser trabeculoplasty (SLT) or medications only.

Materials and methods: A population-based, annual state-transition, probabilistic, cost-of-care model was used to assess OAG-related costs over 5 years. Patients were modeled to initiate treatment in year zero with two iStents, SLT, or medications only. In years 1–5, patients could remain on initial treatment or move to another treatment option(s), or filtration surgery. Treatment strategy change probabilities were identified by a clinician panel. Direct costs were included for drugs, procedures, and complications.

Results: The projected average cumulative cost at 5 years was lower in the two-stent treatment arm ($4,420) compared to the SLT arm ($4,730) or medications-only arm ($6,217). Initial year-zero costs were higher with two iStents ($2,810) than with SLT ($842) or medications only ($996). Average marginal annual costs in years 1–5 were $322 for two iStents, $777 for SLT, and $1,044 for medications only. The cumulative cost differences between two iStents vs SLT or medications only decreased over time, with breakeven by 5 or 3 years post-initiation, respectively. By year 5, cumulative savings with two iStents over SLT or medications only was $309 or $1,797, respectively.

Limitations: This analysis relies on clinical expert panel opinion and would benefit from real-world evidence on use of multiple procedures and treatment switching after two-stent treatment, SLT, or polypharmaceutical initial approaches.

Conclusions: Despite higher costs in year zero, annual costs thereafter were lowest in the two-stent treatment arm. Two-stent treatment may reduce OAG-related health resource use, leading to direct savings, especially over medications only or at longer time horizons.     

Time perception in the diffusion of safety hazard information

Under natural marketplace conditions for a period of 12 weeks, the effect of relevance on time perception was examined in the diffusion of safety hazard information about the use of a brand of tampon. As hypothesized, a two-stage log-linear model showed that the relevance of the health hazard threat was positively related to time distortion.     

A note on optimal procurement contracts with limited direct cost inflation

Laffont and Tirole's [Using cost observation to regulate firms, J. Polit. Econ. 94 (1986) 614-641] pioneering analysis identifies the optimal procurement contract when the supplier can readily inflate his innate production cost without detection. When the buyer has some ability to limit such cost inflation, an alternative contract can outperform the contract identified by Laffont and Tirole. The alternative contract induces substantial pooling, discontinuous production costs and effort supply, and rent that varies non-monotonically with innate cost.     

Public infrastructure provision and ethnic favouritism: Evidence from South Africa

Does coethnicity with the President affect public infrastructure provision in South Africa? Using municipal-level data for 52 district municipalities from 1996 to 2016, we find that municipalities coethnic with the President are associated with higher water infrastructure provision relative to non-coethnic municipalities. Taking into account various political considerations, results show that ethnic favouritism occurs due to ethnic altruism. Our findings remain robust to different specifications of coethnicity thresholds and are applicable to electricity infrastructure provision. Results suggest that in order to minimise ethnic favouritism, politically independent institutions should oversee the allocation of funding and provision of infrastructure.     

BETWEEN DEPRESSION AND HOPE: Affective Mediations of Urban Restructuring in Leipzig,East Germany

In this article, which is based on an empirical analysis of neoliberal restructuring in Leipzig, East Germany, I describe how the study of affective atmospheres adds to our understanding of urban restructuring, showing how collective moods affect (de)mobilization, contestation and the regulation of urban political economy to shed light on the relation between institutional, political and social processes. I demonstrate the relevance of affect for power relations, political interactions beyond rationality, and the rhythms and temporalities of urban restructuring, as exemplified by two prominent atmospheres that characterize Leipzig—post shrinkage depression (PSD) and anticipatory hope (AH).
