Sensitivity Analysis of the Newsboy Model

Avijit Khanra and Chetan Soman

Sensitivity analysis is an integral part of inventory optimization models due to uncertainty
associated with estimates of model parameters. Though the newsboy problem is one of the
most researched inventory problems, very little is known about its robustness. We study
sensitivity of expected demand-supply mismatch cost to sub-optimal ordering decisions in the
newsboy model. Conditions for symmetry (skewness) of cost deviation have been identied
and magnitude of cost deviation is demonstrated for normal demand distribution. We found the newsboy model to be sensitive to sub-optimal ordering decisions, much more sensitive than the economic order quantity model.

The Way Out of the Current Macroeconomic Mess: A Note

Sebastian Morris

The current situation of a large CAD, low growth, and plunging rupee is a result the combination of early withdrawal from the fiscal stimulus and the RBI's monetary conservatism. There is possibly a way out if credit can be expanded to close the differential between the low end government bond yields and the repo, accompanied by a large push on investments with an appropriately structured investment tax credit valid for the next twenty four months. It could crowd in investments to attract FDI and portfolio investments and if the RBI does not allow the current rupee to appreciate in real terms then the CAD could close, with reasonable growth as well. Without these actions the holding out operations on the currency by the RBI can at best delay the further fall in the rupee, and growth which would have a await a protracted recovery from the expected rise in exports some six months from now.

Broadening the Concept of Sustainability and Measuring its Impact on Firm's Performance

Bipul Kumar, Piyush Kumar Sinha, P. R. Shukla, and Abhishek

There is an enhanced awareness among the firms regarding the impact of their marketing and business activities on the environment and society largely due to consumer education, the role of activists and aftermath of some disasters. The firms have started to look at these issues in a more holistic manner which is evident from the sustainability practices undertaken by them. In spite of such efforts, their outcomes regarding sustainability efforts are not in line with the expectations, raising the bigger question whether the firms are displaying and enacting right set of behavior towards sustainability. In view of this background, this paper explores the multifaceted behavioral dimension along with its drivers that contribute towards sustainability in a firm. It also endeavours to develop a measure of sustainability for the firms by including behaviour at the firm level as an additional dimension apart from the economy, social and environmental dimension from triple bottom line perspective. The paper also proposes the relationship between sustainability of the firms and performance metrics including marketing metrics. This paper aims to delineate directions for marketers and policy makers with regard to sustainability marketing.

Role of culture in celebrity endorsement:
Brand endorsement by celebrities in Indian context

Abhishek and Arvind Sahay

Celebrity endorsement is a big market in India and continues to grow bigger. However, inspite of prevalent use of celebrities for endorsement, not all celebrity endorsements have been successful. The list of unsuccessful examples suggest that it will be wrong to consider celebrity endorsement as an effective response to media clutter in all situations inspite of the intensity of involvement people have with celebrities in India. In absence of existing celebrity endorsement theories to satisfactorily explain the phenomenon in India, this paper uses the lens of culture to develop propositions on how customer attitude towards celebrity endorsements is a function of cultural parameters in emerging countries like India. We build our argument by using culture to explain the congruence between celebrity and consumers for elaborating celebrity endorsement in Indian markets.

Inter-sectoral Terms of Trade and Aggregate Supply
Response in Gujarat and Indian Agriculture

Ravindra H. Dholakia and Amey Sapre

In this paper we empirically investigate the role of inter-sectoral terms of trade in determining the growth performance of agriculture in Gujarat and All India during the period 1960-2011. Terms of trade reflects price signals and economic incentives for producers and hence could be a determinant of supply response and growth performance of agriculture and the whole economy. We identify structural breaks endogenously in inter-sectoral terms of trade and analyse phase wise growth performance in distinct periods in both Gujarat and all India. Empirical analysis supports the hypothesis that favourable terms of trade for agriculture lead to a higher growth in agriculture and the whole economy. The results show a strong evidence for positive price elasticities of supply in agriculture and almost rules out the possibility of backward bending supply curve. Favourable terms of trade for agriculture are an additional factor for the high growth trajectory of Gujarat agriculture not emphasized in the literature.

Academic Research Productivity: What may be "reining"
in the Indian B-School?

Arindam Banerjee

The article points at some historic reasons for poor productivity in research, including unproductive competition among institutions due to a false sense of self sufficiency, lack of adequate research infrastructure at the institution level and, the long standing government policy in India that has considered teaching to be the core activity in our University system. It emphasizes the need for collaborative action across institutions that by themselves do not have the wherewithal to upgrade the quality of research. It also stresses the need to build specialized competence in individual faculty members to strive for excellence in a core academic activity, be it research, teaching or executive training and administration. The traditional view of a faculty being a superior performer in all aspects of academics may not yield the results needed to attain global standards of excellence.

Planning the Activities of Doctors in a Teaching Hospital

Debjit Roy, Sahil Narang, and K. V. Ramani

Doctors in a teaching hospital perform a variety of teaching, research, seminar, and in-patient care activities in addition to managing outpatient volumes. In this paper, we study
the weekly activities of a doctor in a large teaching hospital in southern India, where the doctors daily work load has grown primarily due to large patient volumes (during the year 2010-11, the hospital handled a daily load of 5,000 outpatients, 2,000 inpatients, and 125 surgeries) and large student intake per year (about 2000 students in various health disciplines). Ineffective doctor activities plan often resulted in missed activities, long patient
duration of stay (3 days between successive visits), long doctor hospital hours (more than 10 hours per day), and low patient satisfaction levels. We propose alternate plans for doctors'
activities without compromising their involvement in other activities and maintaining the same quality of patient service. The period of stay of the out-patients as well as doctors hospital hours are reduced substantially, mutually benefiting both the hospital and the patients.

Processes, Strategies, and Performance Aspects of
Open Innovation in Information Technology
Sector - Insights from Experts

Sudeep K. Krishnan and Rekha Jain

Open innovation paradigm considers that in order to advance technologies and markets, firms can and should leverage internal and external knowledge, ideas, expertise, and paths to market. This is in contrast to the traditional or closed model of innovation management, where organizations usually leverage the in-house capabilities for innovations. Even though the concept of open innovation has received much interest in management research, majority of the studies on open innovation to date have been mostly exploratory in nature. We used semi-structured interviews to gain experts' perspective on open innovation concepts in the Information Technology (IT) sector. Twenty four interviews were conducted with top management executives in IT firms across India, Europe, and Australia over a period of eight months. A content based analysis of these interviews using open coding was used to investigate experts' perspective of open innovation, strategic relevance of open innovation, and industry perception and trends of open innovation adoption. We developed a framework to classify open innovation projects based on the market knowledge strategy, innovation objective, and stage of the project. We also analysed the existing openness and open innovation project performance measures as perceived by these experts.

Exploring Openness in Information Technology (IT)
Innovation Projects

Sudeep K. Krishnan and Rekha Jain

Open innovation paradigm considers that, in order to advance technologies and markets, firms can and should leverage internal and external knowledge, ideas, expertise, and paths to market. Open innovation being an emerging area of study, the current body of literature is not extensive enough for posing causal questions. Two in-depth case studies at SAP Co-Innovation Lab and IBM India Research Lab were conducted in this research to explore the operationalization aspects of open innovation principles in Information Technology projects. These cases were used to explain how firms identify, assimilate, and integrate external knowledge. As an output of this study, a model was developed to explain the organizational rationale to collaborate, partner selection process, and execution aspects of open innovation projects.

Degree of Openness and Project Performance: A Multi-Country Empirical Assessment of Information Technology (IT) Innovation Projects

Sudeep K. Krishnan, Rekha Jain, and Rakesh Basant

Open innovation is a paradigm that is based on the concept of availability of abundant knowledge outside the boundaries of organizations. This study identified the influence of degree of openness, strength of appropriability regime, and project management maturity on the performance of open innovation projects. Performance was measured based on reduction of technology transfer time from research labs to business units, time to market innovations from the business units, and degree of innovativeness of the outcome. Data from 92 open innovation IT projects across India and Europe were used to test the proposed hypotheses using multiple linear regression and binary logistic regression. We developed an index termed Partner Collaboration Intensity (PCI) to measure degree of openness based on number of partners, intensity of collaboration, and innovation funnel openness. Results showed that specialized research or market partners reduced technology transfer time from research labs to business units. Results also indicated higher values of PCI index, higher strength of appropriability regime, and higher levels of project management maturity positively influenced reduction of technology transfer time from research labs to business units. Results of the logistic regression model showed that all parameters except higher strength of appropriability regime had a positive correlation with the occurrence of breakthrough innovations compared with incremental innovations.
