Periodic review policy for a two-echelon closed-loop inventory system with correlations between demands and returns

Abstract: In this paper, we consider a two-echelon closed-loop inventory system with remanufacturing as the recovery option for returns, and develop deterministic and stochastic models for the system under periodic review where demands and returns are correlated. For the stochastic situation, we consider two cases – emergency shipment and allocation – depending on whether the shortage quantity, if any, at the higher echelon is expedited on an emergency basis or allocated to the lower echelon, respectively. Numerical examples are provided, followed by a discussion of results. One of the major findings of this research is that although correlations between demands and returns reduce the variability of net demand, which is expected to bring down the total cost of the system, the same, on the contrary, may actually go up or go down with correlations between demands and returns depending on the set-up and the parameters of the system. Finally, concluding remarks are presented.

Preference-Based Privacy Markets

Abstract: In the modern era of the mobile apps (the era of surveillance capitalism - as termed by Shoshana Zuboff) huge quantities of surveillance data about consumers and their activities offer a wave of opportunities for economic and societal value creation. ln-app advertising - a multi-billion dollar industry, is an essential part of the current digital ecosystem driven by free mobile applications, where the ecosystem entities usually comprise consumer apps, their clients (consumers), ad-networks, and advertisers. Sensitive consumer information is often being sold downstream in this ecosystem without the knowledge of consumers, and in many cases to their annoyance. While this practice, in cases, may result in long-term benefits for the consumers, it can result in serious information privacy breaches of very significant impact (e.g., breach of genetic data) in the short term. The question we raise through this paper is: Is it economically feasible to trade consumer personal information with their formal consent (permission) and in return provide them incentives (monetary or otherwise)?. In view of (a) the behavioral assumption that humans are `compromising' beings and have privacy preferences, (b) privacy as a good not having strict boundaries, and (c) the practical inevitability of inappropriate data leakage by data holders downstream in the data-release supply-chain, we propose a design of regulated efficient/bounded inefficient economic mechanisms for oligopoly data trading markets using a novel preference function bidding approach on a simplified sellers-broker market. Our methodology preserves the heterogeneous privacy preservation constraints (at a grouped consumer, i.e., app, level) upto certain compromise levels, and at the same time satisfies information demand (via the broker) of agencies (e.g., advertising organizations) that collect client data for the purpose of targeted behavioral advertising.

Leadership Excellence: The Asian Experience:

Abstract: The globalised world needs people who exhibit courage, confidence, and vision and will to provide leadership based on holistic worldview, and cultivate flexibility, and admit diversity. Leadership excellence lies in adopting innovative approaches that foster understanding and build bridges across ethnic, racial, cultural and religious groups besides promoting social welfare, economic development, and tolerance of all religions and cultures.Asia provides one of the most inspirational role models for leadership excellence in an ancient Indian king, namely, Ashoka the Great (299–234B.C).In this paper we present a Case Study on Ashoka the Great. In order to understand his leadership excellence we focus on the vision, mission and action on which his wholesome leadership was based. The main objective of this paper is to bring out a few relevant points, which may contribute to the development of leadership excellence, which is the much focused topic in the field of management theory and practice.
