A New Congruence Axion and Transitive Rational Choice

Lahiri Somdeb

Rationality in choice theory has been an abiding concern of decision theorists. A rationality postulate of considerable significance in the literature is the weak congruence axiom of Richter [1971] and Sen [1971]. It is well known that in discrete choice contexts of the classical type [i.e. all nonempty finite subsets of a given set comprise the set of choice problems], this axiom is equivalent to full rationality. The question is: whether a weakening of the weak congruence axiom would suffice to imply full rationality? This is the question we take up in this paper. We propose a weaker new congruence axiom which along with the Chernoff Axiom implies full rationality. The two axioms are independent. We also study interesting properties of these axioms and their interconnections through examples.

Field Trial of Vastrapur Cartons

Srivastava S M and Girja Sharan

We present in this paper the results of road transport trial of newly developed tomato packaging named Vastrapur Carton. Farm fresh tomatoes were taken from Khanderaopura village to Rajkot a distance of 250 km. Two trials were made. In one trial, entire truck was loaded with Vastrapur Carton only. This was done to determine the effect of physical location of cartons in the carrier on damage to produce and to packages. The result revealed that the damage to produce was more on the lower tiers than the upper, more near the axle than away from it, more on the left side (towards the shoulder of the road) than the middle and rightward. In second trial, one-half of truck was loaded with conventional 'Peti' and other half with Vastrapur Carton. Overall damage to produce in 'Peti' was found to be higher (4.6%) than in Vastrapur Cartons (2.8%). This difference is like to increase with increase in transport distance.

A Consequence of Chernoff and Outcasting

Lahiri Somdeb

The purpose of this paper is to prove by induction the theorem (in Aizerman and Malishevsi [1981]) that a choice function which satisfies Chernoff's axiom and Outcasting can always by expressed as the union of the solution sets of a finite number of maximization problems. The proof we offer is considerably simpler than the one in Aizerman and Malishevski [1981]. In Moulin [1985], a discussion of a similar result is available. Our framework closely resembles the one of choice theory as enunciated in Moulin [1985]. It is well known that a combination of Chernoff's axiom and Outcasting is equivalent to a property called Path Independence (See Moulin [1985]).

Science, Sustainability and Social Purpose: Barriers to Effective Articulation, Dialogue and Utilization of Formal and Informal Science in Public Policy

Anil K. Gupta

A quick look at the leading scientific journals on development brings out one thing clearly: the almost total absence of positive, creative, green voices of innovator and inventors who are solving technological and institutional problems on their own without any outside help. Why is this gap so conspicuous? There could be several reasons: (a) we have become so cynical that we just cannot see any sign of hope, and the more pessimistic we are, the higher is our intellectual reputation; (b) editors put a premium on those contributions that tell us in a laboured way why the world is doomed, why nothing works, why markets, state and civil society are all set to disintegrate; (c) the contributions that describe empirical cases of local achievements are not considered intellectually rigorous enough; (d) the scholars are convinced that unless large-scale revolutions take place, there is no chance for small sporadic islands of achievements by unsung heroes and heroines of our society to make any major dent on the problems of poverty and deprivation; and (e) the conceptual filters and techniques of social analysis (so called participatory techniques included) do not equip a genuine seeker of knowledge to discover grassroots innovators and unaided transformers of social change. Millions of dollars are being spent on training in the so-called rapid method of learning and appraising rural realities and yet the result is often more of the same. In this paper, I will not dwell on what is wrong with the world. There is a lot that is wrong and must be set right soon, for instance, lifestyles of elites in the South as well as the North are totally non-sustainable. What I will discuss in this context would be answers that people have discovered to cope with the ironies of everyday life, and the inadequacies of given technological and institutional frameworks. The paper raises issues in communication in and about science and how the connections between 'little science' and the 'big science' can be made.

Fishing in the `Troubled` Waters: Recognizing, Respecting, and Rewarding Local Ecological Knowledge, Innovations and Practices Concerning Aquatic Biological Diversity

Anil K. Gupta

The study of indigenous ecological knowledge has become an important building block of any participatory approach to natural resources management. It is not the outsiders alone who benefit from the study of indigenous ecological knowledge but even the communities themselves may benefit a great deal if they are provided the opportunity to learn from each other as well as from formal science. In this paper, I look at the relationship among knowledge providers and the outside users with specific reference to aquatic biological diversity. Given the asymmetric relationship among the knowledge providers and the users, I draw attention to the efforts made by Honey Bee Network in influencing the ethics and equity of the knowledge exchange among various stake holders. I discuss the concept of sacred waters and other institutions for conserving aquatic biodiversity. Different kinds of material and non-material incentives for individuals and communities are described. Suggestions are made for changing the ethical basis of knowledge and resource exchange among those who conserve resources and those who use them besides other policy and management interventions that can empower local communities and enrich modern science and technology in the context of aquatic biological diversity.

Agenda for Change before the Republic of India

Singh J P

Based on the electoral history of past 13 General Elections in the country, the paper argues that while the electorate has been pushing the political parties towards coalitions and grand alliances, the same are unlikely to be stable or effective. It proposes that long with the constitutional reforms for the choice of a leader and longevity and stability of the government, the opportunity should be utilized to resolve other issues that have come to the fore in the Indian democracy. Towards this end, the paper proposes an agenda for change before the Republic of India that includes apart from the various provisions of the constitution, the issues that have rocked the nation and steps needed to meet the future challenge.

WTO Agreements and Indian Agriculture: Retrospection and Prospects

Satish Y. Deodhar

By the end of 1999 World Trade Organization (WTO) will complete its five years of existence. At that time, re-negotiation on Agreement on Agriculture (AOA) will also begin. It is time to take a retrospective look at what were the expected gains for India, how was the AOA implemented, and ponder over India's prospects in the up-coming re-negotiations. While the predictions of various macro-models about the gains to Indian agriculture and farmer were not unequivocal, their implicit assumption of perfectly competitive export markets is also questionable. Under imperfectly competitive export market structure, improvement in the terms-of-trade for Indian agriculture may be very limited. Whatever little improvement in terms-of-trade may occur, it may not have a favourable effect as agricultural supply response to changes in terms-of-trade is quite ambiguous. Moreover, the ex-post gains accruing to Indian agriculture so far seem to be very little since developed countries have used various escape routes in the WTO agreements to minimise their reform commitments. India will have to concentrate on non-price factors to improve welfare in the agricultural sector. The prospects of getting additional gains in the up-coming re-negotiations hinge on how India can take maximum advantage of the existing clauses of the AOA, and, to what extent it is successful in amending some of the clauses to its advantage.

Dynamic Demand Analysis of India Domestic Coffee Market

Satish Y. Deodhar and Venkatram R

Coffee, although an important commodity in India agricultural exports, has faced fluctuating international prices and decreasing unit value realisation, especially in the post-reform period. Hence, domestic market for coffee cannot be neglected altogether. In fact, Coffee Board has proposed a promotional campaign to increase domestic demand for coffee. In this context, it becomes necessary to understand weather the emphasis should be on price incentives or nonprice factors. We estimate coffee demand for the Indian domestic market using the dynamic error-correction methodology (ECM). Results show that while demand for coffee is inelastic in the long-run, it is highly inelastic in the short-run. This suggests that Coffee Board may focus efforts on non-price factors rather than price incentives in their generic coffee promotional campaign.

GEB Reforms: A Note on Regulatory Strategy and an Approach to Privatisation

Sebastian Morris

Briefly the proposal is for market competition in generation, through the development of a hybrid wholesale and retail (for bulk consumers alone) market. It is not a marker for all the electricity in the system, but largely a market that would allow distribution-cum-generation companies to purchase power from each other, and form pure generators; and would also allow bulk purchases and captive generators the choice of supply and customer. A market for generation, while allowing distribution companies the comfort of having some distribution assets, would lead to quicker development of the market and allow easier privatisation. The transmission assets of the GEB would need to be in a PSU with 50% shareholding by the state government and all other shares held by consumer interests including farmers' cooperatives, households and industry associations and at least 25% of the stock disbursed through the stock market.

Axiomatic Characterizations of Voting Operators

Lahiri Somdeb

In this paper we provide a model for the analysis of the electoral process. We prove some theorems in this paper, which characterize some voting operators. Apart form other well-known voting operators existing in the literature, we also provide an axiomatic characterization of the first past the post voting rule. In a final section, we take up the problem of a rationalizable voting operators. It is observed that except in the trivial case where every feasible alternative that is voted for by somebody, is chosen, no other voting operator is rationalizable. However, we are able to offer a necessary and sufficient condition for voting operators, to always select the best elements from the feasible set, according to a reflexive, complete and transitive binary relations.
