Assessing NSEs Daily Zero Coupon Yield Curve Estimates: A Comparison with Few Competing Alternatives

Vineet Virmani

This study assesses and compares, on select criteria of evaluation, the time series of daily term structure estimates provided by the National Stock Exchange (NSE) [using the Nelson-Siegel (1987; NS) methodology] with author's own estimates of NS, Svensson (1992; SV) and Cox-Ingersoll-Ross (1985; CIR). While no model comes across as best on all criteria of evaluation, NS as estimated by NSE (and in this study) turn out to be the worst of the lot. Wherever CIR comes out to be better than SV, however, the difference is only marginal. As none of the models came out to be best on all days, given the numerical tractability of parsimonious models and availability of relatively cheap computing resources, it is suggested that NSE report estimates based on 3/4 competing specifications and not just using NS, which should be phased out. A suitable alternative exists in SV. [Preliminary Draft. Please Dont Quote]

A Likelihood Integrated Method for Exploratory Graphical Analysis of Change Point Problem with Directional Data

SenGupta Ashis and A. K. Laha

In this paper we introduce a new likelihood based method, called the likelihood integrated method, which is distinct from the well known integrated likelihood method. We use the likelihood integrated to propose a simple exploratory graphical analysis for the change point problem in the context of directional data. The method is applied to analysis of two real life data sets. The results obtained by application of this simple method are seen to be quite similar to those obtained earlier by different formal methods in most cases.

Checkmate! Winning the Game of Communication: A Study of Conversational Principles

Asha Kaul and Pandit Anuradha

Managerial communication in organizations can well be studied by using drama as a heuristic device to gain an understanding of the complexities governing structure of communication, goals of participants and application of conversational principles. The technique of learning/understanding communication by application of conversational principles and maxims to drama/theatre was applied to dialogue in three absurd plays, namely, The Zoo Story, Endgame, and The Chairs. Analysis indicated that principles and maxims of cooperation and politeness are essential but not necessary prerequisites for communication. Violations of one, namely, politeness principle do not lead to cessation of communication. Communication continues despite violations, for fructification of a higher goal than is evident at the textual level of the dialogue. Extrapolating the findings in the context of the managerial situation, we found the context/situation to be the most significant variable in determining violation of conversational principles

Bangalore Cluster: Evolution, Growth and Challenges

Rakesh Basant

The dynamism and persistence of competitiveness among industrial clusters, even in the wake of globalization and liberalization in the 1990s, has led researchers to explore the causes of dynamic efficiencies at the cluster level. Given its dynamism, the ICT cluster in Bangalore, India has attracted much research and media attention. It is often referred to as the Silicon Valley of India. While the IT sector has brought the city into limelight, it has a fairly diverse portfolio of activities with firms manufacturing machine tools, telecom equipment, electronics products and to some extent auto-components located here. In recent years, the city has also emerged as a premier bio-tech cluster in the country. This paper pools together evidence to explore reasons why Bangalore emerged as a high-tech cluster and the nature of advantages that has contributed to its growth.

Unified Concept of Bottleneck

Chatterjee A K and Saral Mukherjee

The term `bottleneck` has been extensively used in operations management literature. Management paradigms like the Theory of Constraints focus on the identification and exploitation of bottlenecks. Yet, we show that the term has not been rigorously defined. We provide a classification of bottleneck definitions available in literature and discuss several myths associated with the concept of bottleneck. The apparent diversity of definitions raises the question whether it is possible to have a single bottleneck definition which has as much applicability in high variety job shops as in mass production environments. The key to the formulation of an unified concept of bottleneck lies in relating the concept of bottleneck to the concept of shadow price of resources. We propose an universally applicable bottleneck definition based on the concept of average shadow price. We discuss the procedure for determination of bottleneck values for diverse production environments. The Law of Diminishing Returns is shown to be a sufficient but not necessary condition for the equivalence of the average and the marginal shadow price. The equivalence of these two prices is proved for several environments. Bottleneck identification is the first step in resource acquisition decisions faced by managers. The definition of bottleneck presented in the paper has the potential to not only reduce ambiguity regarding the meaning of the term but also open a new window to the formulation and analysis of a rich set of problems faced by managers.

`Commerciality` in International Commercial Arbitration

Anurag K. Agarwal and Jain D Harsh

Enterprises, the world over, now conduct business on a dramatically more international scale. The growth of world economies is directly connected with millions of commercial contracts, which are becoming more international in character owing to global integration. Commercial arbitration has been hailed as the most efficient form of dispute settlement available to participants in international trade. As the purpose of the commercial arbitration is to resolve commercial disputes, often issues have been raised whether a particular dispute is commercial or not. With globalisation and seamless trade the aspirations of global business community, it would be of immense importance to understand the meaning of 'commercial' as construed in 'international commercial arbitration' in some of the major jurisdictions of the world.

A Diagnostic Study of Jawaharlal Nehru Port Trust

G. Raghuram

The Jawaharlal Nehru Port Trust (JNPT), an autonomous body under the Major Port Trusts Act, 1963, was commissioned on 26th May, 1989. The port was originally planned to decongest the Mumbai port and serve as a hub port for container handling for the region. JNPT became the first Indian port to handle more than 1 million TEUs (twenty foot equivalent unit, the measure used for container traffic) in 2000-01. In view of the increasing containerised trade, a third container terminal was tendered in October 2002 and awarded in August 2004 to Gateway Terminals of India Private Limited (GTIPL). GTIPL has begun the construction and operations are expected to begin by early 2006. As stated by the Department of Shipping, "The increased volume of container traffic has put a lot of strain on the existing (landside) infrastructure, leading to the problem of frequent congestion in the port." The author was approached by the Ministry of Commerce for a diagnostic study of JNPT. The study was carried out during February to April 2005. As part of the study, it was decided to keep in perspective three scenarios of traffic: (i) upto 2.5 million TEUs, ie the current levels, (ii) upto 4 million TEUs, ie from mid 2006 as GTIPL becomes operational and (iii) beyond 4 million TEUs, when the fourth box terminal is made operational. This paper presents the analysis and recommendations of the study.

Financial Performance of Private Sector Hospitals in India:Some Further Evidence

Bhat Ramesh and Jain Nishant

This paper analyses financial performance of private hospitals. The study is based on financial statement data of private hospitals for the years 1999 to 2004. Using 25 key financial ratios, the study finds six key financial dimensions. These are: fixed assets age, current assets efficiency, operating efficiency, financial structure, surplus/profit appropriation, and financial profitability/operating cost ratio. The findings suggest that over the years hospitals have shown marginal improvement in financial performance. Though the total amount of debt is not high, it is the cost of debt and ability to service the debt which is making debt burden high for hospitals. The financial risks in this sector are high because of lower profitability and lower operating efficiencies. We discuss the implications of the results.

Efficient Subsidisation of LPG: A Study of Possible Options

Ajay Pandey and Sebastian Morris

The budget contained an announcement that the central government would actively explore the option of using an appropriate form of the 'food stamps' or an alternative scheme to improve the efficacy and reduce the cost of the current system of administration of food subsidies. The announcement provides an opportunity to discuss the issues of subsidy on account of LPG and device a system of subsidisation based on 'LPG Stamps' or some other scheme to improve the efficacy of subsidisation and remove the large distortions created by the current system. LPG subsidy has grown historically and has become quite high because of aggressive growth in connections and increase in per connection consumption in addition to rising input costs. Given that there is evidence that LPG subsidy has been ineffective in increasing penetration in rural and poorer households, there is a case for capping and targeting LPG subsidy. Otherwise it can explode over time unless new connection growth is curbed, which is indefensible. The best option to curtail LPG subsidy would be to eliminate it straight away. However, there are at least two factors which are likely to make it difficult. Firstly, the input costs are high (from a historical point of view). Secondly, the high input prices coupled with lack of preparatory ground work may result in political mobilization against the move. The next best option which sharply focuses on the deserving segment is direct subsidy to below poverty line families. These households may be given up to 8 coupons every year. Each coupon can be used for subsidy for a cylinder. A separation of the identification and issuance of coupon is critical to the success of this scheme. As clarified elsewhere in the study, by coupon we mean any technology which allows the target group to get a well-defined and secured entitlement. It could be paper coupons with security features or smart cards, using IT for identification and entitlements. Direct subsidy to BPL family through coupon would allow them to pay cash equal to retail price less the subsidy per coupon. This amount and a coupon would entitle them to get a cylinder. The coupon surrendered to the dealer would be in turn be surrendered by him to the Oil companies, who would pay equivalent cash to the dealer. In fact, dealer may get an additional compensation for the cost of accounting and administration. The BPL coupon holders may be allowed to trade the coupons as this would convert the LPG subsidy to income subsidy. Even if the transfer or trade is not allowed, it is bound to take place and the net effect of that would be sharing of subsidy between intended beneficiary and some intermediary. Targeting LPG subsidy to BPL consumers may encounter problems in improper identification about which Oil companies need to work closely with district/ local administration so as to proactively eliminate inappropriately classified consumers. Targeting BPL consumers for LPG subsidy also leaves open the possibility of non-BPL consumers taking connections in the name of BPL consumer and that of BPL consumers opting for multiple connections. Both problems are to some extent self limiting (due to conflict and due to connection charges) but warrant closer examination of new connections under BPL category. Coupon based direct subsidies require efficient administrative support associated with coupon distribution, appropriate documentation, coupon accounting, collection and cash reconciliation. Coupons have to be difficult to copy and print to prevent frauds etc. This can be ensured by printing of coupons at a security press, or by suitable IT enabled mechanisms. Irrespective of any method of LPG subsidy reduction, there is a need to examine the taxes built in currently estimated gross subsidy. The net subsidy to the consumers should be the basis of elimination otherwise the target is self-defeating (by being higher) and not justifiable (elimination of gross subsidy means moving from net subsidy to net tax regime). Even if the state governments continue to collect sales tax, the central government which also collects taxes and simultaneously bears subsidy should neutralize the subsidy estimate from central taxes. The state governments need to be persuaded to retain the current amount of sales tax (but at a lower rate) otherwise states get higher revenue and the price target goes up. In case the state governments were to pay truant on this issue, there is a need to explore whether differential issue prices can be used as a deterrent. Another issue which warrants closer examination is the impact of volatility of input costs on retail prices. Had the industry been competitive, this would not have been a major issue. Clearly, some oversight or regulation is required so that prices are changed at appropriate intervals and are still neither excessive nor too low. It would be appropriate to set up a regulator to review periodically review the input costs and allow changes. He may allow prices on the basis of average cost with a lag or may prescribe a band linked to input costs and may monitor the prices to prevent any abuse. The rationalisation of prices and of tax reform in this sector is long overdue. These need to be simultaneously pursued. It is possible for the entire sector to move towards a revenue neutral cenvat based tax regime. That in itself and the direct subsidization of kerosene and LPG through coupons is necessary to remove all the distortions. The ill effects of the distortions that result in misuse, diversion, revenue loss, and added environmental and governance problems can only be feasibility addressed by the movement away from price based subsidies to direct subsidies. Similarly kerosene subsidises if correctly targeted and administered can have large spillovers in the management of subsidies in LPG.

CBD and TRIPS: Empowering Knowledge - Rich, Economically Poor People through IPR Reforms

Anil K. Gupta

The discussion in the recent COP 8 (Conference of Parties) meeting ending on March 31, 2006, the subject of Prior Informed Consent and protection of intellectual property rights of knowledge holders remained very contentious. I discuss various kinds of incentives that need to be provided for protecting the IPRs of local communities and individual knowledge holders, innovators without undermining the goal of people to people learning. The policy reforms are suggested in primarily five areas viz., registry of innovation and traditional knowledge. Prior Informed Consent, disclosure requirement, licensing and other issues relating to collecting societies (collective rights of innovators), etc. It is hoped that the deliberation of the next meeting of the Article 8J working group prior to COP 9 would draw upon these lessons and incorporate the same in the discussion.
