The different faces of coupon elasticity

Coupons account for over two-thirds of all consumer promotional efforts initiated by the manufacturers of consumer goods. In this study, the impact of coupons on brand sales is investigated and how that impact decays over the life of the coupon is demonstrated. Specifically, we present an econometric model that can capture coupon effects in terms of equivalent price reduction, account for coupon effects over time, allow inference of coupon effects when retailers decide to double or triple the coupon value, and provide both self-coupon and cross-coupon elasticities at different levels of aggregation. A widely used sales response model is adapted, and an analytical model is proposed to estimate both the self-coupon and cross-coupon (face value) elasticities of sales at the store level. From the store-level elasticity estimates for a given week, the authors analytically derive the coupon elasticities for the chain level by aggregating across stores, and over the life of the coupon by aggregating over time. The proposed sales response model is estimated with the data obtained from three markets for various product categories, and the coupon elasticities are computed. The proposed framework allows one to demonstrate the hypothetical equivalence of a shelf-price reduction for a given coupon face value in each week. Also, the effect of doubling the face value of a coupon results in more than a proportionate increase in elasticity. The authors find that both self and cross-coupon elasticities are much smaller in magnitude than the average self and cross-price elasticity measures reported in the literature.

Employee well-being attribution and job change intentions: The moderating effect of task idiosyncratic deals

We developed and tested a research model in which employee well-being human resource (HR) attribution differentially influences the intention to change jobs across organizations (i.e., external job change intention) versus that within the same organization (i.e., internal job change intention). Furthermore, we posited that task idiosyncratic deals (I-deals) moderated the relationships between employee well-being HR attribution and external and internal job change intentions. Results indicated that employee well-being HR attribution was negatively related to external job change intention, but positively related to internal job change intention. Further, task I-deals significantly moderated the relationships between employee well-being HR attribution and external and internal job change intention. Specifically, employee well-being HR attribution played a less important role in reducing external job change intention when task I-deals were high rather than low. On the other hand, high task I-deals significantly strengthened the positive relationship between employee well-being HR attribution and internal job change intention. Our study extends the careers literature by differentiating the impact of employee well-being HR attribution on job change intentions within an organization compared with that across organizations and the important role of supervisors in enhancing or mitigating these effects.     

“Moving” land across borders: spatial shifts in land demand and immiserizing effects

The rush for land acquisition has attracted considerable attention from the scientific community, although actual research on the topic remains thin. This paper attempts to break new ground by studying the potential effects of land deals in the context of a small open economy subject to exogenous shocks. In particular, it makes three main arguments: first, an increase in world prices of the agro-business sector causes skewed effects in the subsistence sector; second, an attractive premium offered by hosts to lure investors may have immiserizing effects; and third, technological efforts will have favorable effects if host countries adopt policies to revitalize agriculture.

Development and validation of a hospitality idiosyncratic deals scale

This study explores middle and senior hotel managers’ perceptions of their own idiosyncratic deals (i-deals) and develops a scale to measure i-deals in the Chinese hospitality industry. The study uses a mixed research method consisting of a questionnaire survey of 675 middle and senior hotel managers and in-depth interviews with 20 knowledge workers in the hotel industry in mainland China. The findings reveal that there are three types of i-deals in the Chinese hospitality industry: (1) career and incentives i-deals; (2) task i-deals; and (3) flexibility i-deals. The study proposes and validates a three-dimensional scale of hotel managers’ i-deals, thereby enriching our understanding of the idiosyncratic terms of employment in the hospitality industry.     

Impacts of land leases in Oromia,Ethiopia: Changes in access to livelihood resources for local people

Large-scale land deals have attracted considerable attention for various reasons, including their implications for local livelihoods. While some view the phenomena as a development opportunity, encompassing improvement in the livelihoods of local people, others argue that it is an impoverishing scheme. Ethiopia ranks among the top in terms of the size of land leased out over the last decade. Land is a major resource of state control and investment in Ethiopia. As the foundation of their livelihoods and identity, it is simultaneously a vital resource for the local people. Highlighting the importance of land for local livelihoods and state-society relations and employing a political-ecological approach, this paper analyzes the outcomes of two land lease cases for the local people in Bakko Tibbe district of Oromia, Ethiopia. The findings show that the land leases induced a significant decline in local people’s access to land, resulting in a significant reduction in crop production and livestock husbandry. The land leases also dismantled longstanding land-based social relations in both production systems. Based on empirical evidence from specific localities and contextualizing the local livelihood dynamics within broader political-economic conditions, this study contributes to the ongoing debate on livelihood impacts of global land deals.     

Antecedents and consequences of idiosyncratic deals: A frame of resource exchange

This study examines the antecedents and consequences of both timing and content of idiosyncratic deals (i-deals) for attracting and retaining valuable employees. A resource exchange frame theorizes the influence pattern of personal individualism value, social skill, and perceived insider status on i-deals timing. Individualism and social skill are expected to relate to both ex ante and ex post i-deals; perceived insider status is anticipated to relate only to ex post i-deals. The frame also suggests that i-deals’ content and personal development relate primarily to relational and balanced psychological contracts; the other ex post i-deals, flexibility and workload reduction relate to transactional psychological contracts. The frame was tested with data collected from 289 Chinese employees in the telecommunication industry.     

The Coordination and Preference of Supply Chain Contracts Based on Time-Sensitivity Promotional Mechanism

To encourage retailers to submit orders as soon as possible, manufacturers usually launch a time-sensitivity promotional mechanism that the earlier you order, the cheaper the wholesale price will be in advance of the selling season. This paper aims to investigate if the mechanism can improve supply chain performance. A dyadic decentralized supply chain system comprising a single manufacturer and a single retailer is viewed as a research framework. Initially, a benchmark model is proposed to provide a criterion-referenced for coordinating the supply chain in a non-standard distribution environment. Second, a time-sensitive wholesale price contract is constructed to confirm that the mechanism can coordinate the supply chain. However, the retailer accepts the entire forecast risk under the contract. An improved contract called a time-sensitive revenue-sharing contract is constructed based on the notion that the manufacturer shares partial forecast risk. The results show that participants can arbitrarily divide the optimal supply chain’s expected profit between the constructed price contracts; however, two differences exist between the contracts, that is, participants have contract preferences. Finally, a numerical analysis and a few management insights are given.     

How do flexible work arrangements alleviate work-family-conflict? The roles of flexibility i-deals and family-supportive cultures

Flexible work arrangements (FWAs) are becoming common in emerging economies, though it is not clear if and how employees benefit from them in terms of their work-family balance and well-being. In contrast to previous work that used structural-functional explanations, we argue that FWA implementation should be depicted within its socio-political and socio-cultural context. We used survey data collected from 213 professionals in Istanbul, Turkey to examine the roles of flexibility i-deals and perceived family-supportive culture in the relationship between FWA availability and these employee outcomes. Results supported the hypothesis that i-deals mediate the relationship between FWAs and work-to-family conflict. Furthermore, perceived family supportive cultures predicted both work-to-family and family-to-work conflict and moderated the relationship between i-deals and family-to-work conflict. Finally work-to-family conflict mediated the relationship of flexibility i-deals and family supportive cultures with perceived general health. These finding are discussed for their implications for employees who are trying to balance their work and family lives and for organizations who are considering implementing FWAs.
