Price,Rebate, and Returns Supply Contracts for Coordinating Supply Chains with Price‐Dependent Demands

Channel rebates and returns policies are common mechanisms for manufacturers to entice retailers to increase their order quantities and sales ultimately. However, when the underlying demand depends on the retail price, it has been known that channel coordination cannot be achieved if only one of these mechanisms is deployed. In this article, we show that a policy that combines the use of wholesale price, channel rebate, and returns can coordinate a channel with both additive and multiplicative price‐dependent demands. In addition to determining the sufficient conditions for the contract parameters associated with the equilibrium policy, we show that multiple equilibrium policies for channel coordination exist. We further explore how the equilibrium policy can be adjusted to achieve Pareto improvement. Other issues such as the maximum amount of expected profit that the manufacturer can share under the coordinated channel, the structural properties of the contracts under both the additive and multiplicative price‐dependent demand functions are also discussed.     

Measuring the influence of built neighborhood environments on walking in older adults

There is a need for greater understanding of how perceptions and objective measures of the physical environment influence physical activity among seniors. The goal of this study was to examine the degree of association between perceived and objective characteristics of the neighborhood environment and the relation of each type of measurement to neighborhood walking in older adults. Data on self-reported frequency of walking in the neighborhood and perceived measures of neighborhood environment from 105 older adults were linked to objective measures assessed by geographic information systems and an audit instrument. Perceived and objective measurements of the built environment exhibited a low degree of agreement (kappas: <.20). After adjustment for education, age, and gender, presence of a mall was positively associated with neighborhood walking in both the objective and perceived models.

Do childcare policies and schedule control enhance variable time workers' work–life balance? A gender analysis across European countries

Variable time work is no longer abnormal in the post-industrial economy and is accelerating due to digitisation and the COVID-19 pandemic. Previous studies have revealed a causal relationship between working time variability and work–life balance at the individual level; however, there has been less discussion of the role of the institutional context. This study examines the interplay among childcare policy, schedule control, and its relationship with work–life balance. We conducted a multilevel analysis using the European Working Conditions Survey. The analyses revealed that childcare policy has a U-shaped relationship with work–life balance for female variable time workers without schedule control. In contrast, workers with schedule control and male workers did not have a curvilinear relationship with the outcome. Our analyses imply that sufficient childcare intervention and its interaction with schedule control are necessary to offset the negative effect of childcare services on work–life balance.
