Is There Seasonality in the Sensex Monthly Returns?

Pandey I M

The presence of the seasonal or monthly effect in stock returns has been reported in several developed and emerging stock markets. This study investigates the existence of seasonality in Indias stock market. It covers the post-reform period. The study uses the monthly return data of the Bombay Stock Exchanges Sensitivity Index for the period from April 1991 to March 2002 for analysis. After examining the stationarity of the return series, we specify an augmented auto-regressive moving average model to find the monthly effect in stock returns in India. The results confirm the existence of seasonality in stock returns in India and the January effect. The findings are also consistent with the "tax-loss selling" hypothesis. The results of the study imply that the stock market in India is inefficient, and hence, investors can time their share investments to improve returns.

Government Role in Road Toll Collection: The Coimbatore Bypass Experience

G. Raghuram and Kheskani Deepa

India has the second largest road system in the world with a road length of 3.3 million kms. In the past 50 years, while the aggregate length of the roads has increased eightfold, the traffic has increased to almost twentyfold, resulting in congestion. To reduce the congestion and improve road quality, the central and state governments have focused on road development projects in the recent years. Public private partnerships have also been leveraged through the Build, Operate and Transfer (BOT) framework. This paper discusses various issues in toll based BOT projects, with the focus on a specific case study. L&T Transportation Infrastructure Limited, the BOT operator has been facing financial problems, experiencing a difficult time collecting tolls from the Athupalam Bridge segment of the Coimbatore Bypass project. Though the government has been trying to resolve the problem, it has not arrived at any positive solution as yet. This paper highlights the lessons from the Coimbatore Bypass experience for the future road BOT projects.

Private Public Partnership in Urban Infrastructure Projects: Getting Sweet Curd from Spoilt Milk?

Biju Varkkey

Rapid growth in urban population has made Solid Waste Management an important issue for civic administration. The 74th amendment of the Constitution of India and Municipal Solid Wastes (Management and Handling) Rules 2000 has made municipal solid waste management the responsibility of urban local bodies (city corporations and municipal corporations). Further, the Supreme Court of India, acting on Public Interest Litigation directed all urban local governments to install scientific solid waste treatment plants before a set timeline. Installing a scientific waste management system was a costly proposition, which many urban bodies found difficult to bear. Many have sought participation of the private sector in solid waste management. The city corporation of Thiruvananthapuram also invited participation of Poabs Group to set up a waste processing plant in the corporation owned land outside the city. Right from inception the project ran into social and political opposition. The investor was enticed by the government to stick to the project by offering various concessions. There were interface issues of very serious nature between the plant and corporation employees whose support was absolutely necessary for continued, viable operation of the plant. However, the concessions remained in paper and the operations of the plant reached a stalemate. Based on the experiences of the private investor, various governance and policy level implications for public private participation in urban infrastructure projects (specifically solid waste management) are discussed.

Exports of Agri-Products from Gujarat: Problems and Prospects

Ravindra H. Dholakia

Agri-products are defined to include products of agriculture & allied activities, fishing, forestry, and manufacturing industries, like food & food products, tobacco, textiles, paper, furniture, etc. Gujarat has a revealed comparative advantage in the exporting activity over the other states since, as per GITCO Study (November 2001), more than one-fifth of the exports of the country originate from Gujarat. Gujarat has the revealed comparative advantage in ground-nuts, oilmeals, castor oil, poultry & dairy product, spices, sesame & niger seeds, processed food & vegetables & fruits, cotton yarn & fabric, man-made textiles, handicrafts, and cotton raw including waste. Fresh fruits & vegetables, floriculture, and fish are not the areas of strength for Gujarat so far. Based on the large sample survey conducted by GITCO (November 2001), several features of the exports originating from Gujarat are also examined. Exports of agri-products originating from Gujarat represent excess supply rather than exclusive supply to the foreign markets. The prospects of the domestic demand and production of the agricultural sector in Gujarat are examined. The dismal picture of the declining real income in Gujarat agriculture during the late nineties is not supported by several other evidences. On the contrary, Gujarat has a very vibrant and responsive agricultural sector. It has an achievable potential to grow at 4.5% to 5% p.a. over the next 8 to 10 years. The paper concludes by identifying some areas for further research.

Competitiveness of Indian Manufacturing: Finding of the 2001 National Manufacturing Survey

Pankaj Chandra and Sastry Trilochan

In this paper we present findings of the second national survey on the competitiveness of Indian manufacturing. The paper develops hypotheses on the competitiveness of firms in the manufacturing sector and addresses some key questions on the characteristics of world class firms in India. We analyze the processes and practices that such firms have adopted to become world class. More important, we highlight firm level practices that are preventing Indian firms from becoming globally competitive. The findings point towards three distinct aspects of manufacturing management that define the capabilities of the firm, i.e., strategies related to dynamic control of shop floors, network linkages and innovation. It is found that firms that build distinctive technological and managerial capabilities in these domains are able to compete globally. The paper provides a comparison with manufacturing capabilities of competitors in China and draws lessons for organizing large scale manufacturing. It also provides an assessment of the changes that have happened in manufacturing priorities and strategies in India since our last survey that was conducted in 1997 and highlights the implications of these changes.

Pension Reforms in India: Myth, Reality and Policy Choices

Gupta Ramesh

Escalating costs of the pension system is forcing the Indian Government to reevaluate the formal programmes that provide social security to employees. The government has so far received three official reports (namely, OASIS, IRDA and Bhattacharya), which have examined the issue and suggested several measures to provide a safety net to the aging population. This paper examines the recommendations made in these reports and analyses the potential effects of them. It is organized around five policy questions: 1. Should the reformed system create individual (funded defined-contribution) accounts, or should it remain a single collective fund with a defined-benefit formula? The changeover involves a larger public policy choice issue: who should ultimately bear the risk? Should employees/retirees shoulder those risks alone arising from variations in asset yields and unexpected changes in longevity, or should these risks be shared more broadly across participants, if not society? Choice would depend upon to which group the individual belongs. Financially successful people may believe in individual ownership and choice, while low wage earners may want assured returns because they do not have other resources to fall back upon. Unfortunately most Indians, unlike those in many other countries, are in the latter category which cannot bear any risk, more so in the old age. 2. If individual accounts are adopted, should the reformed system move toward private and decentralized collection of contributions, management of investments, and payment of annuities, or should these functions be administered by a public agency? In privately managed funds, associated problems would be intermediation costs, agency problem (principal-agent fiduciary relationship), and greatly increased costs to administer the plan. Several studies across the world have shown that periodic fee may look deceptively low but, over longer time horizons, the cumulative effect can be dramatic, sometimes reducing the benefits by 30 to 50 per cent. 3. Should fund managers of retirement savings be allowed to invest in a diversified portfolio that includes stocks and private bonds? In recent years equity investments, particularly index investing, have become a favoured strategy. Index funds are subject to tracking error, and being loaded with few big stocks, there are much higher risks in index investing than people perceive. Over the period, real annual return on index funds may be more, but people retire only once. Equity markets are highly volatile and go through long periods of feasts and famine. Guarantees would have to be provided in the form of minimum return or providing minimum basic pension on retirement. World bank studies show that government ends up acquiring conjectural liabilities wherever a pension system based on private providers is mandated. How would that be different from the present system where a government agency (EPFO) provides retirement benefits? 4. Should the government move toward advance funding of its pension obligations for its employees, or should these obligations continue to be financed on pay-as-you-go basis? Studies have shown that a simultaneous implementation of funded, diversified, individual accounts is not a "free lunch" once you properly account for existing unfounded obligations and risk. The Bhattacharya Committees estimates show that the government would have to pay out more on account of pensions to its employees for the next 38 years before the new scheme starts showing reduced government expenditure. These amounts do not include the tax foregone by the government on the employees contribution. Several assumptions have been made about the scheme, which the committee hopes would remain valid and that the future governments would behave responsibly. The proposed scheme does not consider intermediation costs and agency risks; in fact, the committee presumes that agents would behave more responsibly than principals. 5. What should be the level of government fiscal support in the form of tax subsidy, foregone tax collections, grants, administrative costs incurred by its agencies, and level of assumed contingent liabilities in case the government guarantees minimum pension? The crucial question is: how much and to whom is this subsidy accruing? Are beneficiaries of the proposed system the ones who need subsidy? Tax treatment of pension is a critical policy choice. A generous tax treatment may promote savings but may be costly in terms of revenue foregone. Apparently, an exercise in balancing is necessary. The priority should, therefore, be putting in place a policy vision and road map with specific goals in relation to pre-determined milestones. These should include a tax financed and means-tested system for lower income groups. If government cannot afford it, then it has no moral or political justification to even consider providing further tax benefits to privileged income groups. If there are no government funds for the first pillar in the World Bank recommended multipillar system, the third pillar should remain out of policy discussions. Emphasis should be on strengthening the second pillar. Suggested reforms neither enhance efficiency nor make the social security system more equitable. It would only privatize the gains while costs and risk for the government would increase considerably. It would only help well-off segment of society in availing more tax concessions. Present problem in the government pension system is due to successive governments behaving like Santa Clauses ignoring the cost to exchequer. Fund managers would not be able to solve these problems. Specific fiscal and other measures for implementing a feasible and viable pension system in Indian conditions have also been suggested in the paper.

Information Asymmetry and Trust: A Framework for Studying Micro-Finance in India

Sriram M S

The work in the area of microfinance has concentrated on the issue of transaction costs in delivering the financial services to the poor. However, the mechanisms of reducing transaction costs have been mostly in the area of building trusts within local communities and using trust as an effective surrogate for sorting the twin problems of inadequate information and high cost of transactions. The paper presents a theoretical framework to study the field of microfinance from this point of view. There has been significant literature both in Economics as well as in Behavioural Sciences in examining the role of trust in organisational settings. This paper postulates that the element could be extended to networks like self-help groups. Eventually, it tries to identify some thresholds where the concept of trust and social capital can be used as a surrogate to reduce transaction-documentation costs and when the costs become indifferent to the underlying trust in exchanges.

Term Structure Estimation in Illiquid Government Bond Markets: An Empirical Analysis for India

Goutam Dutta, Vaidyanathan K, and Basu Shankarshan

With increasing liquidity of the Indian sovereign debt market from 1997, it has become possible to estimate the term structure in India. However, several frictions that cause individual securities to be priced differently from the "average" pricing in the market characterize the market. In such a scenario, traditional estimation procedures like ordinary least squares using various functional forms do not perform well. In this paper, we find that mean absolute deviation is a better estimation procedure in illiquid markets than the ordinary least square. We further find out a novel liquidity weighted objective function for parameter estimation. We model the liquidity function using the exponential and hyperbolic tangent functions and suggest the most robust model for estimating term structures in India.

Applying Machine Based Decomposition in 2-Machine Flow Shops

Saral Mukherjee and Chatterjee Ashis K

The Shifting Bottleneck (SB) heuristic is among the most successful approximation methods for solving the Job Shop problem. It is essentially a machine based decomposition procedure where a series of One Machine Sequencing Problems (OMSPs) are solved. However, such a procedure has been reported to be highly ineffective for the Flow Shop problems (Jain and Meeran 2002). In particular, we show that for the 2-machine Flow Shop problem, the SB heurisitc will deliver the optimal solution in only a small number of instances. We examine the reason behind the failure of the machine based decomposition method for the Flow Shop. An optimal machine based decomposition procedure is formulated for the 2-machine Flow Shop, the time complexity of which is worse than that of the celebrated Johnsons Rule. The contribution of the present study lies in showing that the same machine based decomposition procedures which are so successful in solving complex Job Shops can also be suitably modified to optimally solve the simpler Flow Shops.

Some Aspects of Organizational Communication in India: An Empirical Study

Dholakia Jigisha

This study, being essentially empirical in nature, is based on primary data relating to Indian organizations. The primary data has been collected through a sample survey based on a questionnaire focusing on the following aspects of organizational communication: (a) Nature of Communication, focusing on the proportion of working time spent in talking and listening and also the perceived extent of non-verbal communication. (b) Communication Content, focusing on the communication of compliments and criticism across levels. (c) Communication Outcomes, focusing on the communication goof-ups and the degree of satisfaction with ones communication dealings within the organization. An attempt has been made in the study to try and examine communication dealings by differentiating between the people working in the Corporate & Academic organizations; and Males & Females. The study highlights significant differences between males and females in terms of several aspects of organizational communication. There are a few differences in some aspects of organizational communication between the people working in the corporate and academic organizations. In most cases, the differences in the given aspects of organizational communication across categories and levels observed in this study seem to corroborate the broad conceptual patterns emerging from the available literature on organizational communication.
