A Comment on Nashs Independence of Irrelevant Alternatives Assumption for Choice Problems

Lahiri Somdeb

In a recent paper, Campbel (1994) shows that if a choice correspondence satisfies Arrow8217;s choice axiom then it has a complete, reflexive and transitive rationalization, even if the domain does not include any set with fewer then m members, where m is a given positive integer. The purpose of this paper is to provide a simpler proof (than the one provided by Campbell) of the same result when the choice correspondences are single – valued i.e., the case of choice functions. In such a situation Arrow's choice axiom is formally equivalent to Nash's Independence of Irrelevant Alternatives assumption.

Role of Culture in Institution Building and Sustenance: The Case of IIMA

Kolavalli Shashi

The paper argues that organizational culture plays a central role in building and sustaining institutions. The process of institution building and sustenance is analyzed using institutional economics and collective action frameworks. The paper examines culture at IIMA, what it was, and is, how it was developed and the role it played in IIMA achieving excellence in some spheres of management education. It is argued that the declining commitment of the faculty to institutional tasks can be traced to erosion of culture more than anything else. The development and sustenance of culture is also shown to be heavily dependent on leadership style.

Some Aspects of Value Added Tax in Indian Economy

Dholakia Bakul H

Comprehensive tax reform has always been an integral part of the overall package of economic policy reforms introduced in a large number of developing and newly industrialising economies in recent years. A crucial ingredient of the tax reform is a large scale reform of the existing system of indirect taxation through the introduction of Value Added Tax (VAT). An attempt has been made in this paper to examine the rationale for introducing VAT in Indian economy as a part of the overall process of fiscal reform and also examine some aspects of Value Added Tax such as the international experience in this regard as well as some specific issues in implementation of VAT in India.

A System Dynamic Study of Apple Movement from Orchards to Wholesale Market

Kayastha Sandeep and Girja Sharan

Two northern states, Jammu and Kashmir (J&K) and Himachal Pradesh (HP) account for most of the apple grown in India. Fruit is graded and packed near orchards and sent to Agricultural Produce Market Committee (APMC), Delhi for auction. This paper presents a simulation model of fruit movement from orchards in HP to APMC market in Delhi. Daily arrival of fruit in Delhi as predicted by the model is compared with the data on actual arrivals from records maintained at APMC. The comparisons appear satisfactory. Simulations indicate that transit delays during peak phase will belong enough to reduce the storage potential of fruit to a negligible level. Cold stores in Delhi, therefore, tare likely to remain under-utilized, which is indeed the case. These results suggest that the systems dynamics approach to modelling is promising.

Availability and Work Targets of Bulldozers

Khandwalla P N, Girja Sharan, and Kumar M Krishna

Setting work targets for machines is an important task for engineering managers, especially where they operate large fleets with machines of different makes and ages. Setting uniform work targets is easier but it does not take into account operating characteristics of machines which could differ with make and change with age. It is suggested here that using analysis of availability of machines can provide an alternate basis to set work targets. Availability analysis of bulldozers is reported here which suggests the feasibility of achieving higher work targets compared to the present 1000 hours per season.

Discovering People Potential: Organizational Constraints and Facilitators

M. R. Dixit and Deepti Bhatnagar

The paper highlights the importance of discovering people potential for organizations. It argues that constant search for people potential in teams and as individuals has to be an important item on organizational agenda, more so in the current context of rapid changes in the environment of today's organizations. Potential discovery processes are needed for fuller utilisation of talents which often remain unidentified and underdeveloped. After presenting a conceptual framework, the paper discusses organizational factors which influence the potential discovery process. It presents the case study of a successful organization which has consciously chosen systems and processes that facilitate the discovery, development and utilisation of people potential. Need for organizational mechanisms to sustain the potential discovery process is emphasised.

Privitization of Ports - Framework for Governmental Action

G. Raghuram

Given the delays and congestions at ports, leading to extensive demurrage charges for ships, a lot of attention on improving port productivity through better management systems and infrastructure developments are being considered. Privatization of ports at various levels is being proposed as a structural solution. The Government of India as well as many of the coastal states in India are examining this issue rather seriously. The author has been involved in a study for a state with a large coastline having over forty notified ports, on this issue of privatization. The objectives of this study were to examine and recommend” (a) Which of the present ports should be privatized? (b) Possible locations for future privately owned ports based on traffic considerations. (c) Which of the port-related services should be privatized? (d) The terms and conditions for selecting the parties for private ownership and/or provision of services. (e) The process of smooth implementation of privatization. As part of the methodology, the author also studied the experiences of a few countries abroad as well as nearly 10 major ports spread all over the country. This paper reports on this study and the development of a conceptual framework for governmental action for privatization of ports.

Fertilizer Plant Modelling: A Simulation Study

Girja Sharan, Tripathy Arabinda, and Kumar M Krishna

A Simulation model of a fertilizer plant has been made. It includes activities from production to despatch, from the plant site. Input to the model is daily demand which comes to the plant as despatch instructions. The model includes provision for internal generation of realistic daily demand. Output gives the state of the system at any desired interval of time. Simulation reports can be used by managers for planning logistics and other operational aspects at the plant site. SLAM II has been used for modelling.
