Optimal Consumption Plans with Uncertain Planning Periods

Lahiri Somdeb

In this paper we study the one sector optimal growth model with uncertain planning horizons. We prove the non-existence of steady states, and the dependence of optimal capital stock at time 't' on the conditional probability of a 't' period planning horizon given that the planning process does not terminate before time 't'. We illustrate our results using a consumption optimal growth model and Cobb-Douglas technology.

Role of Women in Risk Adjustment in Drought Prone Regions

Anil K. Gupta, Yugandhar Mandavkar, Amin Surekha, and Shah Rekha N

Households strategies for adjustment with risks is an understudied subject, in general but role of women in this regard has remained particularly neglected. Author had taken up a comprehensive study of Impoverishment in Drought Prone Regions in collaborations with Swiss Dev Corporation and NABARD during 1981 in a drought prone district (Ahmednagar) of Maharashtra. The purpose was to identify the policy options for rural credit for drought prone regions. Subsequently during 1985-86, some of the women member of the households were revisited to understand the changes if any in terms of repertoire of the risk adjustment strategies. The paper summarizes some of the ways in which rural women contribute towards risk adjustment with special reference to the problems of credit. This is a preliminary draft and a more comprehensive study will be separately brought out.

Optimal Maintenance and Life of Machines, Subject to Time Varying Rate of Depreciation

Lahiri Somdeb

In this paper we study the optimal maintenance policy and life of machines with time varying decay rate of quality. Many management problems involve the determination of the life or horizon of an activity in combination with the management of it. We study a particular class of such problems, and obtain solutions for optimal maintenance policies and life of machines.

Marine Fisheries Development: An Outlook at Turn of the Century and Key Policy Issues

Srivastava Uma Kant

Marine fisheries will have to play a crucial role in augmenting supplies both in the domestic as well as export markets. Thrust of the development will be deep sea and brackish water resources. The exploitation of these resources, particularly deep sea, will require a rapid transition from chartering of vessels to joint ventures and owned fleet with modern and sophisticated technology. Creation of sizeable owned fleet would require massive credit and fiscal support. This thrust for exploitation of deep sea resources can be sustained with consorted attempts to formulate and implement strategies for product development and marketing in both domestic as well as export markets. This will also require the attention to develop the necessary infrastructure to handle such vessels, onshore processing facilities, better management of fishing harbors, cold chain grid in the domestic markets, development of transit and terminal markets at wholesale and retail levels. Boat Building Yards will have to take up new challenges. This also throws up challenges for net marketing industry in this country. All these developments would also require massive efforts for training and development of manpower. This paper deals with all these areas in a systems framework and suggests appropriate policy support measures for strengthening various elements of the system.

Marketing of Fresh Water Fishes in India

Srivastava Uma Kant

In this paper an attempt has been made to analyze the marketing pattern (use flows, physical flows, channel flows and fishermen's share in consumer rupee) of fresh water fishes and to summarize the key areas for action to improve the marketing system and farmer's share in consumer rupee. Before discussing the marketing pattern, demand-supply scenario, price behavior of fish vis-à-vis other commodities and role of inland fisheries in meeting the demand is presented. The most important concern for improving the fish marketing system is to give larger share of consumer's rupee to fisherman/fish farmers. As the same time availability of fish to consumers including those located in the hinterland, need to be assured at reasonable prices. Keeping these two major concerns in view, following areas of actions can be suggested for improving inland fish marketing system: (i) Market Regulations, Weights and Measurements, (ii) Strengthening of Transit-and-Terminal Markets and setting up of Retail Markets, (iii) Packing and Transportation, and (iv) Vertical Integration of Cooperative from Primary to Transit and Terminal Markets.

Considerations in Evolving a Comprehensive Leasing Policy for Inland Waterbodies for Fish Production

Srivastava Uma Kant

Inland fishery resources can be classified in terms of rivers, fresh water ponds, reservoirs and brackish water bodies (ponds for culture, term's farms for capture/filtration, lakes, swamps and estuaries). Some States have made an attempt to license the river stretches to the fishermen for a small fee but in view of the declining catches from the reverie resources, it is doubtful whether reverie fishermen in Gujarat can be made to pay anything. There is, however, a need for conservation of fish breeding and genetic resources in the reverie sector. The question of lease/royalty is important for the other three sub-systems of inland sector i.e. fresh water ponds, reservoirs and brackish water water-bodies. This paper is designed to highlight some of the critical elements in decision-making about the leasing of these water-bodies. The paper makes recommendations for the lease duration, rent and institutional support for each of the inland fishery sub-systems.

Priority Areas for Research in the Operations of Small Enterprises

Srivastava Uma Kant

Failure and sickness of small venture during project cycle has received very little attention by the developmental institutions, specialized research institutions and management specialists. Failure and sickness is caused due to problems in pre-operative and operative phases of a project. In operative phase, which broadly could be considered as project pre-planning and implementation phase, internal and external factors cause delay in project implementation. Delay in implementation often seriously jeopardizes the financial viability of the project right from the initial stage. Major problems in operative phase include faulty project formulation and implementation, non-availability of raw materials, poor financial management, training and retraining of manpower, marketing problems and technical problems associated with production. Survey research and case research are important methods of research in small ventures. Survey research is not only time consuming but also does not provide insight at micro-level into the reasons, which lead to failure and sickness in small ventures. Case researches of selected small enterprises from various regions of the country can be an extremely effective tool for generating the required understanding of small business. It is desirable that major specialized research institutes should take the lead in generating ideas and providing regional and state levels should pool the researches and share the funding with each other.
