Individual-level information systems adoption research has recently seen the introduction of expectation-disconfirmation theory (EDT) to explain how and why user reactions change over time. This prior research has produced valuable insights into the phenomenon of technology adoption beyond traditional models, such as the technology acceptance model. First, we identify gaps in EDT research that present potential opportunities for advances-specifically, we discuss methodological and analytical limitations in EDT research in information systems and present polynomial modeling and response surface methodology as solutions. Second, we draw from research on cognitive dissonance, realistic job preview, and prospect theory to present a polynomial model of expectation-1 Vivek Choudhury was the accepting senior editor for this paper. disconfirmation in information systems. Finally, we test our model using data gathered over a period of 6 months among 1,143 employees being introduced to a new technology. The results confirmed our hypotheses that disconfirmation in general was bad, as evidenced by low behavioral intention to continue using a system for both positive and negative disconfirmation, thus supporting the need for a polynomial model to understand expectation disconfirmation in information systems.

According to the UN Sustainable Development Goals in 2016, the demand for resources will require natural resources equivalent to two and three planets by 2030 and 2050, respectively. The linear economic model driven by a "take-make-dispose" philosophy is unable to manage the demand and supply balance in consumption of natural resources. This imbalance is affecting the sustainability of the countries and enterprises as well as affecting the global supply chain leading to socioeconomic and environmental risks and volatility. Realizing the future resource scarcity challenge, the current linear economy model is giving way to the circular economy model. The circular economy model focuses on careful alignment and management of resource flows across the value chain by integrating reverse logistics, design innovation, collaborative ecosystem, and business model innovation. This article examines how circular model is pushing the companies in developing economies like India to design and implement business models that are based on reduce, reuse, and recycle paradigms.

A ccurate inventory records are key to effective store execution, affecting forecasting, ordering, and replenishment.Prior empirical research, however, shows that retailer inventory records are inherently inaccurate. Radio Frequency Identification (RFID) enables visibility into the movement of inventories in the supply chain. Using two different field experiments, the current research investigates the effectiveness of this visibility in reducing retail store inventory record inaccuracy (IRI). Study 1 used an interrupted time-series design and involved daily physical counts of all products in one category in 13 stores (8 treatments and 5 controls) of a major global retailer over 23 weeks. Results indicate a significant decrease in IRI of approximately 26% due to RFID-enabled visibility. Using an untreated control group design with pre-test and post-test, Study 2 expands the number of categories to five and the number of stores to 62 (31 treatment and 31 control stores). Results show that the effectiveness of RFID in reducing IRI varies by category (ranging from no statistically significant improvement to 81%). Results also suggest that RFID ameliorates the effects of known determinants of IRI and provide the key insight that the technology is most effective for product categories characterized by these determinants.

W e propose a model to study expectation confirmation in information systems. The proposed model is based on the assimilation-contrast model and prospect theory, and suggests that both are needed to account for the magnitude and direction of the deviations between experiences and expectations. Using the technology acceptance model's (TAM) primary construct-namely, perceived usefulness-expectations and experiences were conceptualized and operationalized to test our model. Data were collected in a field study from 1,113 participants at two points in time. Using polynomial modeling and response surface analysis, we demonstrated that our model offers a good explanation of the relationship among information systems expectations, experiences, and use. We discuss theoretical and practical implications.

Purpose – The purpose of this paper is to examine the social entrepreneurship focussed organizations in the context of challenges faced and strategic actions adopted by them during the different stages of self-sustainable business model design and implementation. Design/methodology/approach – The empirical context involves the use of qualitative multi-case-based research methodology for data collection and analysis. The sampling involves undertaking the field study of social entrepreneurship oriented organizations, which have made the perceptible socio-economic difference in the lives of the rural and semi-urban population lying at the base of the pyramid (BoP) in India. Findings – The findings of this study are presented in two complementary stages. The first stage involves presenting the narrative incorporating the emergent themes and key characteristics of the social entrepreneurship focussed organizations based on the field-research based data collection and analysis. The second stage involves mapping the challenges with the strategic actions thereby formulating a challenge-action framework. Research limitations/implications – The paper strengthens the belief in social entrepreneurship as a viable alternative for creating a market-based ecosystem at the BoP. This paper highlights the conception of social entrepreneurship in terms of challenges and corresponding strategic actions. Practical implications – The derived challenge-action framework will enable the social entrepreneurs to learn, understand, design and implement a better informed and transparent market-based business models at the BoP resulting in reduced market risks and uncertainty. Social implications – The government needs to recognize the social entrepreneurs as partners having a separate legal entity as well as consider their inputs and on-field experiences while framing the policies in favor of the BoP. In addition, the government needs to facilitate the social entrepreneurs in leveraging the government network and institutions for reaching the BoP segment. Originality/value – This study is an original contribution to the field of social entrepreneurship in number of ways. The first contribution lies in reviewing the research literature from the definition perspective. The second contribution lies in reviewing the research literature to determine the key challenges faced by the social entrepreneurs at the BoP. The third contribution lies in identifying the propositions and conceptualizing the challenge-action framework depicting the challenges faced and strategic actions required by the social entrepreneurs for successful and sustainable social intervention at the BoP.
