Growth of New Stoves - A Model

Girja Sharan

Promotion of new wood stoves has been made into a nation-wide time-bound program. At present, setting of targets in each area proceeds somewhat arbitrarily. Generally, no account is taken of the mechanics of absorption. This paper deals with this problem. A mathematical model of the process is formulated. Under reasonable assumptions, it leads to a linear, time-invariant, discrete system. Possible growth patterns that emerge are illustrated. The model is easily built and easily solved. It can be helpful to those who plan, implement and monitor the program.

European Economic Community: Underlying Motives and Their Implications

Gaikwad V R

This is the Introductory chapter to Author's forthcoming book entitle, “ European Economic Community and Non-European Communities”. What is happening in Europe is gigantic with far-reaching implications for Indian and other developing countries. The paper analyses in depth the ideas of Jean Monnet, the Father of European Economic Community, and the basic motives underlying formation of EEC and their implications. Common Market is only a strategy to achieve the primary politico-economic objective namely, a United States of Europe. The process by which Common Market might become a supra-national state is shrewdly set up in such a way that process is gradual and imperceptible. The recent developments in East Europe and Russia are not spontaneous but part of the long-term strategy for uniting Europe and people of “European Origin”, and for “Unity of West”. Europe's march from Nationalism to Supra-nationalism may lead to Euro-racialism, creating a threat of War of Races in near future. India and other developing countries which are mostly non-European countries have to keep in mind these implications of EEC.

Threat Bargaining Problems with Incomplete Information and Correlated Beliefs

Lahiri Somdeb

In this paper we provide a general framework for studying threat bargaining games with incomplete information and correlated beliefs. In this framework we obtain a characterization of the Kalai-Smorodinsky solution without any monotonicity assumption. The approach adds a dose of realism to the already existing literature on threat bargaining games.

Large Lift Plants - Performance

Girja Sharan and Kayastha Sandeep

Large lift irrigation plants (LIPs) are a recent development in parts of Gujarat. These are commonly sited on old tanks, some on intermittent streams and canals. Water is lifted to a high point of command through a riser and then led by gravity through pipes to various distribution chambers. A need had arisen to examine their performance. Accordingly, a continuos, deterministic mathematical model of a typical LIP has been made. The system is viewed as a negative feedback, automatic (on/off) control. Curve number method is used to compute runoff and moisture balance method, for effective rainfall. Simulations using actual (historical) daily rainfall were carried out to determine irrigation needed and possible. Long term value of latter is taken as a more realistic index of system capability than that originally projected. Actual performance is compared with it. Possible additional uses of simulation in design and operations are highlighted.

A Decision Support System for Improving Railway Line Capacity

G. Raghuram and V. Venkata Rao

This paper describes the design, implementation and experimental with an interactive software system which determines the line capacity of a section of running freight trains. The schedules of passenger trains are given. The package can find the effect of decisions related to infrastructure investments like improved signalling, additional stations, additional tracts at stations and additional tracks between the stations in order to improve line capacity. This model was used with test data on an important section (100 kms lenth between 2 major yards with 20 stations) in the Western Railway a zone of the Indian Railways. Experiments were conducted to determine i) the effect of changing a portion of the section from single track to double track; ii) the effect of improved signalling and higher trains speeds; and iii) the best possible starting times for freight trains at either origin.

A Periodic Review Inventory Model for Stochastic Demand with Two Storage Facilities

Shah Nitin and Shah Y K

In this paper a periodic review probabilistic inventory model for a single item with two storage facilities is developed; one warehouse is owned by the system under consideration (which is referred to as OW) and the other is a rented warehouse (RW). The capacity of OW is W units. Any quantity larger than W is to be kept in RW and are gradually withdraw in batches of K units. The model determines optimum values of lot-size q and k. An example is given to illustrate the results obtained.

Threat Bargaining Problems with Incomplete Information and Nash Solution

Lahiri Somdeb

In this paper we extend the framework of threat bargaining games to include those with incomplete information. In this set up we address ourselves to two significant problems: (1) Under what conditions would 'truthful' revelation of the disagreement payoffs by a Nash equilibrium of the threat bargaining game? (2) Obtaining a characterization of the Nash bargaining solution without the Independence of Irrelevant Alternatives Assumption. Our framework of analysis is general enough to include within its purview the study of non-cooperative bargaining problems with incomplete information, played by Bayesian players, although the specific problem addressed to in this paper does not fall in that category.

Consultant and his Role in Organizations

Parikh Indira J and Selvan Tamil S

Whenever there is a collectivity of people with structures, tasks and interphases between people and systems there are some individuals who by choice or by the need of the hour or situation become consultants, advisors, experts and problem-solution givers. This paper examines how consultants emerge, are seen, what roles they undertake in organizations, what factors influence the consultant's roles and what are the new definitions and dimensions of a consultant's role. It identifies the context in which an organization and the consultant interphase. It states the different phases of evolution of organization growth and how the role of a consultant changes. These dimensions are discussed based on experiences of many consultants and existing literature. Most of the role descriptions are borrowed from existing literature and from experiences and discussions with consultants and industrialists. In the Indian context due to constant flux and transition, consultants have to review and define an appropriate role for themselves to contribute to the design and development of institutions and formal work organizations.

Egalitarian Departures from the Ideal Point

Lahiri Somdeb

In this paper we propose a new solution to bargaining or group decision problems, which requires an arbitrator to choose that point on the Pareto frontier of the feasible set where losses in utility from the ideal point are equal for all the agents. The solution is motivated by ones already existing in the literature. We then present two modes of characterizing this solution which uses familiar axioms in bargaining theory and also some axioms which are intuitively plausible variants of those existing in the literature. The two key axioms are Independence of Common Monotone Transformation modulo the Ideal Point and Redundancy of Additional Alternatives Other Than a Reference Point.

Ghana Public Sector Finances: Recent Developments and Issues

Gupta Anand P

This paper provides a perspective on how Ghana has managed her public sector finances since the inception of the economic reforms programme in 1983. It reveals that Ghana continues to have a deficit in her public sector finances-Ghana's current public sector deficit (5.5% of GDP) is of about the same size it was before the commencement of the economic reforms programme. This is contrary to the general perception of Ghana having succeeded in eliminating her public sector deficit, and that too over a relatively short period. The paper also shows that between 1982 and 1987 the Government of Ghana's tax and nontax revenue as % of GDP grew by 8.5 percentage points (from 5.6 to 14.1%), with export duties alone accounting for roughly one-half of this impressive growth. With the government revenues growing, government consumption expenditure has also grown-from 6.5% of GDP in 1982 to 10.6% in 1987. In other words, government consumption expenditure increases alone absorbed 48.2% of the revenue growth-and as much as 113.9% of the growth in collections from export duties. The Ghana policymakers need to ponder over this development. Finally, a word must be said about capital spending which has risen from negligible level in 1983 to 8.3% of GDP in 1988. This is indeed a major achievement: capital spending has been used for rehabilitation of the country's economic and social infrastructure which was allowed to deteriorate throughout the 1970s. however, with public savings being relatively small (e.g. 2.6% of GDP in 1988), the government has chosen to finance the shortfall (in resources required to finance higher levels of capital spending) through external resources, which Ghana so far has been able to mobilize on highly concessional terms. But what about the future? In case the terms harden, will Ghana be able to afford them?
