Despite the recognition of how important expertise coordination is to the performance of software development teams, understanding of how expertise is coordinated in practice is limited. We adopt a configural approach to develop a theoretical model of expertise coordination that differentiates between design collaboration and technical collaboration. We propose that neither a strictly centralized, top-down model nor a largely decentralized approach is superior. Our model is tested in a field study of 71 software development teams. We conclude that because design work addresses ill-structured problems with diverse potential solutions, decentralization of design collaboration can lead to greater coordination success and reduced team conflict. Conversely, technical work benefits from centralized collaboration. We find that task knowledge tacitness strengthens these relationships between collaboration configuration and coordination outcomes and that team conflict mediates the relationships. Our findings underline the need to differentiate between technical and design collaboration and point to the importance of certain configurations in reducing team conflict and increasing coordination success in software development teams. This paper opens up new research avenues to explore the collaborative mechanisms underlying knowledge team performance.

Consumers possess a mental account that stores the worth of items purchased and yet to be consumed. Reference prices act as the book values of these items. Movements in the account—the comparison between the reference price and the price paid at entry, and the comparison between the benefit of consumption and the reference price at exit—yield hedonic benefits. The reference price is determined by a psychological process of adaptation to the price evoked by the trade. The model is integrative, in that it explains a wide array of observed anomalies such as sunk-cost effects, payment depreciation, reluctance to trade, preference for pre-payment, and the flat-rate bias. The model also generates new testable implications.

There is a growing interest on developing efficient ways of incorporating environmental considerations into business practices in order to meet both consumers' demand for green products/services, and the firms' sustainable profitability. The main contribution of this article is in developing an integrated revenue management framework to address a firm's greening (investment) effort, pricing and inventory decisions. It is assumed that the firm inaugurates a green product along with its existing product. Even though the firm offers both the green and regular product at differentiated prices, the market segmentation as a result of this price differentiation is regarded as imperfect. This imperfect market segmentation causes a demand leakage mainly due to the heterogeneity among the customers' willingness-to-pay. These effects are included in our proposed model and simplified analytical solutions are developed to solve the same. Additional scenarios where a firm experiences a price-dependent stochastic demand with an unknown distribution is also modeled. This scenario is addressed using a distribution-free approach based on Scarf' s rule. The performance of the proposed methods and the significance of the modeling framework are finally corroborated through several simulations. This analysis provides a sustainable environment, production and retailing framework while still augmenting profitability using fundamental tools from revenue management

Herding and Social Media Word-of-Mouth: Evidence from Groupon

Modern online retailing practices provide consumers with new types of real-time information that can potentially increase demand. In particular, showing past product sales information can reduce uncertainty about product quality, inducing consumers to herd. This effect could be particularly salient for experience goods due to their inherent high uncertainty about product quality. Social media word-of-mouth (WOM) can increase product awareness as product information spreads via social media, increasing demand directly and also amplifying existing quality signals such as past sales. This study examines the mechanisms behind the strategy of facilitating herding and the strategy of integrating social media platforms to understand the potential complementarities between the two strategies. We conduct empirical analysis using data from Groupon.com which sells goods in a fast cycle format of “daily deals”. We find that facilitating herding and integrating social media platforms are complements in generating sales, supporting that it is beneficial to combine the two strategies on social media-driven platforms. Furthermore, we find that herding is more salient for experience goods, consistent with our hypothesized mechanisms, while the effect of social media WOM does not differ between experience goods and search goods
