Econometric Modelling of the Indian Cotton Sector: Disaggregate Analysis

Naik Gopal and Jain S K

Keeping in view the magnitude, importance, interlinkages among the variables and the high involvement of a large number of decision makers and the government intervention in Indian cotton sector, this study aims at understanding and quantifying the interrelationship among the important variables of this sector through an econometric simulation model. This model explains interlinkages among cotton farming, spinning and weaving sub-sectors through 27 equations. The estimated model performs satisfactorily in terms of goodness of fit, sign, significance of the coefficients and short-and long-term predictability. Forecasts were made for the period 1992-93 through 2001-2002. The trends indicate that the production of cotton would grow slightly slower growth rate than its consumption. The production of long staple cotton will increase faster than that of medium staple cotton. In the spinning sector, the export of cotton yarn will increase substantially. Therefore, the production of cotton yarn will increase at a higher growth rate than its consumption. The growth rates in the production of medium and coarse count yarn will be almost same. The demand for and production of decentralised fabric will increase at the growth rate of 3.63 per cent. However, the demand for and mill fabric will increase but the export of decentralised fabric will grow faster. The demand, production and price of khadi fabric will remain more or less stagnant. The simulation results of two different policy variables namely, export of cotton and yarn show that the promotion of export of yarn is more beneficial for the Indian cotton industry and raw cotton export does not have any impact on fabric export.

Economic Analysis of Industrial Agroforestry: Popular (Poulus Deltoides) in Uttar Pradesh (India)

Jain S K

To meet raw material requirements. Wimco.the biggest match industry in India, has been promoting popular based agroforestry thorough agroforestry projects approved by National Bank for Agricultural and Rural Development (NABARD) in the northern region of India since 1984. This study aims at evaluating the performance of polular based agroforestry in terms of income, employment and environmental impact. Popular based agroforestry is economically viable and relatively more profitable in comparison to many of the crop rotations followed in the study are. Popular plantations with intercrops are more remunerative in a plantation of seven years instead of eight years. This land use system is capable of providing employment opportunities on farms and the preserving ecological system as well. The cost charged by Wimco for technical advice, however, reduces the income from poplar plantation substantially. With farmers gaining experiences, farmers can expect high dividends in subsequent rotations.

Analysing Technology Strategies: Some Issues

Rakesh Basant

A firm's technology strategy is influenced by the 'technology regime' in which it operates. The regime is broadly defined by a combination of variables capturing industrial structure, nature of technical knowledge and the policy environment. Together, these variables determine the opportunity and appropriability conditions faced by a firm in a well defined industry. Given these broad relationships, firms' technology strategies may differ across industry groups. In addition, differences in technology strategies within an industry group may be induced by some form specific characteristics like size, nature and level of diversification, technological and other capabilities. Analyses of strategy using the modified the Strucutre-Conduct-Performance paradigm at the industry level have been unsatisfactory; industry heterogeneity gives rise to significant differences in the strategies of firms within the same industry. Dissatisfaction with the definition of industries has resulted in the use the concept of strategic groups, which differentiate a group of firms from others within a given industry in terms of their strategic choices. The value of the concept of strategic group lies in its role as a meaningful explanatory variable between the level of the firm and the industry. It should be capable of delineating extant structures and explaining (or predicting) conduct of firms within an industry. The major research problem with the strategic group approach is how to identify the different strategic groups in practice and how to allocate firms within an industry to the different groups which make up the industry's industrial structure. The present paper attempts a selective review of studies pertaining to technology strategy to explore parameters which can be used to define strategic groups within an industry. It is argued that nature of technology, industry and firm characteristics have major implications for theory and action related to the content of technology strategy and for the processes through which it is developed and implemented.

Trends of Outpatient Visits and Inpatient Admissions in Public Hospitals of Ahmedabad, India over last 24 years

Saha Chandrahi and Dileep Mavalankar

This paper tries to show the trend of registration of patients (indoor & outdoor) in various medical institutes of Ahmedabad which are run by the Ahmedabad Municipal Corporation (AMC) in last 24 years (1971-94). The Civil Hospital which is run by State Government was also studies for the same time period for comparison. The trend analysis of the registered patients is based on the secondary data available from AMC. The study shows that in last 24 years there is substantial decline in outdoor patients in most of the hospitals under AMC inspite of 3.6% annual increase in city population. Only Civil hospital shows a rising trend. Overall number of indoor admissions have increased somewhat in AMC hospitals. But it was mostly in tertiary hospitals, while in smaller hospitals & maternity homes number of indoor admissions have declined. On the other hand there is a marked rise in number of private nursing homes over this period. The paper also tried to explore the likely reason for such trend in patient registration. It also discusses the policy implications for providing quality health service to the citizens.

Modelling a Vegetable and Fruit Market to Aid Modernisation

Girja Sharan and T. Madhavan

We present in this paper, an operational study of CJ Patel Wholesale Fruit and Vegetable Market of Ahmedabad city using simulation. This market was built in the year 1996 in order to reduce congestion in another older market. Viewed as a dynamic queuing system, simulations suggest that even though the buildings are designed to last a lot longer, utility of this complex as a market place will diminish considerably in just 10 to 15 years. So much so that by the year 2010 A.D., it may become necessary to move out yet again. Such an eventuality can be warded off, if loading, unloading and other handling systems are modernised and made speedier. A more general conclusion is that design procedures for such markets in future need to recognize these as dynamic queuing systems and not just an assembly of buildings and road.

Changing Perspective on Rural Credit between Mid-80s and Mid-90s - Experiences of two West Bengal Villages

Samar K. Datta and Chakraborti Milindo

Credit is a 'pure service' transaction between two points of time rather than a spot market transaction in 'pure goods'. Because of the time gap involved between sanction and realization of credit, the players in the market confront several kinds of risks, many of which are not independent of the socio-economic environment. Against the backdrop of the institutional changes in the form of establishment and strengthening of the Panchayats in rural West Bengal over the last two decades, the present study is an attempt to capture the attendant changes in rural credit market between mid-1980s and mid-1990s from the experiences of two villages in the district of Birbhum. In doing so, it compared the profile and mode of operation of prevailing moneylenders and lending institutions with those documented in an earlier study carried and in the same two villages and made an endeavour to find out as to whether the changes in the functioning of both formal and rural credit have led to greater accessibility to credit of the rural masses, a larger base for agricultural production through productive use of assets and ensuring better prices for farmers. The experiences of several successful multipurpose primary credit societies in India, the Indian Grameen Services, Hyderabad, the Bangladesh Grameen Bank and the Chinese Township and Village Enterprises are cited to provide some future guidance in improving the rural credit scenario in West Bengal.

Comparative Financial Systems: Financial Liberalisation, The Black Market Exchange Rate and Demand for Money in South Korea, Taiwan and Thailand

Chotigeat Tosporn and Pandey I M

Central to the unbridled economic success of the Pacific-Rim countries is their financial liberalisation from 1981 to 1990, their ratio of M2/GDP (measure of the depth of the financial sector) is as large as the M2/GDP of the OECD economies. The Pacific-Rim countries have also been moving --albeit at different speed-- to liberalise their equity and bond markets and integrate them more closely into international financial markets. This paper first summarises the most essential aspects of the financial liberalisation and innovation process in Thailand, Taiwan and South Korea. Second, it tests at various stages of financial liberalisation for an appropriate overall functional form of demand for money for each country, using the Box-Cox extended auto-regressive model with data from January 1970 through June 1989. Black market exchange rate is used in the model as a key variable, instead of a conventional variable of the official exchange rate. The empirical results confirm that real income, expected inflation and expected inflation and expected depreciation in the black market exchange rate are appropriate scale and opportunity cost variables in the long-run money demand function, especially for South Korea. In addition, depreciation in the black market exchange rate is found to be a negative effect on the demand for money in all cases, but there is no empirical evidence to indicate that the black market exchange rate influences the demand for money differently over the period before and during the on-going financial liberalisation process. Therefore, the Pacific-Rim countries in this study must carefully select an appropriate exchange rate policy to support their economic goals because (a) the black exchange rate is significant to their economies, and (b) neither a decline in the black market nor an alignment of the black market and official exchange rates will occur as long as the financial liberalisation has not reached maturity and/or exchange rate control still exists.

An Operational Study of CO Patel Vegetable and Fruit Market of Ahmedabad

Girja Sharan and T. Madhavan

We present in this paper, an operational study of CJ Patel Wholesale Fruit and Vegetable Market (CJP Market) of Ahmedabad city. The market is viewed as a dynamic queuing system. A simulation model is constructed. Simulations are used to generate statistics on congestion as the volume of trade is increased form the present level to what would be expected by the year 2010 A.D. This market was built in the year 1996 in order to reduce congestion in another older market. While the buildings are designed to last a long time, simulations show that its handling capacity will get saturated much sooner, most likely by the year 2010 A.D. Based on this work, it is argued that programe to modernize loading, unloading and other handling systems must be initiated now. Further, design procedures for such markets need to recognize these as dynamic queuing systems and not just an assembly of buildings and road.

Generalized Shapely Value for Games with a Coalition Structure

Lahiri Somdeb

In cooperative games with transferable utility, there is usually no restriction on the possible coalitions that can materialize. A significant departure from this tradition, occurs in Moulin [1995], where the concept of admissible coalitions arise. In this paper we consider cooperative games with admissible coalitions, requiring that both the grand coalition, as well as, the null coalition are always admissible. We call such games, 'games with a coalition structure'. We define the concept of a core for such games and introduce a generalization of the notion of Shapley value. We define this generalized Shapley value to be the unique value satisfying the Dummy Player Property, Anonymity and Linearity. All these properties have been adapted from the standard context to our framework in such a way, that the existence of a unique value satisfying these properties is guaranteed. We subsequently consider specific coalition structures and obtain closed form solutions for the generalized Shapley value in each case.

Process of Developing Venture Capital Activity--: A Study of Three Indian VCFs

Pandey I M and Fliegal F C

This study investigates the venture capital activity development process in India. The discussion covers the issues of the initiation of venture capital fund, investment strategy and evaluation criteria and the value addition by venture capital firms (VCFs). The history of modern venture capital in India is not very old, which was formally introduced in 1986-87. In the initial years, VCFs in India encountered a number of problems in developing their business. From in-depth case studies of three VCFs of India, it is found that all of them went through the initial constraints of not knowing the venture capital business well and learnt through trial and error and failures and mistakes. They faced problems in raising funds and evaluating prospective ventures. All of them initially focused their investment on the high technology business. But gradually they shifted their focus towards potentially high-growth, high profitable businesses and not just high-tech businesses. It is also noticed that VCFs maintained a closer link with the assisted firms in order to ensure the success of the venture capital.
