A Comment on the Independence of Irrelevant Expansion Assumption for the Non-Symmetric Nash Choice Function

Lahiri Somdeb

In this paper we establish three distinct results: a) a unique characterization of the family of non-symmetric Nash choice functions using an Independence of Irrelevant Expansions Assumption; b) a characterization of the entire family of choice functions (containing those determined by weighted hierarchy and those which are 'mongrel' choice functions only) satisfying Pareto Optimality, Scale Translation Covariance and Weak Independence of Irrelevant Expansions; c) as a by-product of (b) we obtain a characterization of the family of choice functions determined by a weighted hierarchy by slightly strengthening the Weak Independence of Irrelevant Expansions assumption.

Cooperative Rural Banking: and Anad Shows the Growth-Oriented Path

Desai B M and Namboodiri N V

This paper is about how Anand Farmers Service Cooperative Bank could be successful under the same macro rural credit policies that governed most rural financial institutions. This bank is innovative in both the spirit of its cooperation and rural banking. It could be so because of (1) strategy of nothing succeeds like success howsoever small it is, (2) organizational continuity that has made this bank democratic, decentralized and yet accountable, and (3) organizational principles of vertical structure, high density, larger reach and diversified services for rural clientele. The paper also shows that these three factors have enabled this bank to be financially viable and growth-oriented. And it concludes with some suggestions on what macro rural credit policies may continue and which ones of them need modifications to extend the experiment of this bank.

A Watering System for Potted Plants

Girja Sharan, Kumar Sanjay, and Kumar M Krishna

This paper deals with design of a watering system for a large number of potted plants that form part of a landscape. Installation of the system was motivated by a desire to save labour, time and water. The system now in operation consists of delivery rings to which are attached large number of microtube emitters. Each emitter takes water to one pot, each ring caters to a cluster of 20 to 25 pots. More can be added when needed. Flow rate from emitters can be varied by changing the length of tube. Cost of the system was Rs.5800/- and it takes care of about 600 potted plants. Presently no provision has been made for fertigation of filtering, which is proposed to be added later.

Demand for Farm Tractors: Two Models

Girja Sharan

Demand prediction for farm tractors is of interest to industry and government. Two different models were developed earlier. One termed a causal model, was similar to a model of a process driven by potential difference. The other was based on time series analysis. In this paper the performance of these is examined over a ten-year span, and their special merits discussed.

The Equal Loss Choice Function Revisited

Lahiri Somdeb

Choice theory is a mathematical discipline which studies the problem of choosing a point from a set of points by studying the mathematical properties of maps assigning an outcome to each choice problem in some class of choice problems. A large literature has grown up concerning choice problems in Euclidean spaces. A typical choice problem is then a compact, convex, comprehensive subset of the non-negative orthant of a finite dimensional Euclidean space, containing a strictly positive vector. For such choice problems, Yu (1973) and Freimer and Yu (1976) have introduced a class of solutions obtained by minimizing the distance of the “ideal point”, measured by some norm. The equal loss solution is one such. However neither Yu (1973) nor Freimer and YU (1976), succeeded in characterizing such solutions axiomatically. It was in Chun (1988) that we find a complete axiomatic characterization of the equal loss solution for the first time. A brief glance at the proof of Chun's theorem, begs the questions, whether there is a simple alternative proof. The purpose of this paper is to provide such a proof, by modifying the technique suggested by Thomson and Lensberg (1989), in their axiomatic characterization of the egalitarian solution. In the later sections of the paper we consider choice problems with variable dimensions and obtain an axiomatic characterization of the equal-loss-choice function using a reduced choice problem property, first invoked in the relevant literature by Peters, Tijs and Zarzuelo (1994). We are thereby able to drop the assumption of Strong Monotonicity with Respect to the Ideal point, which is used in the original characterization.

Knowledge Building in Industry-Technology Institution Joint R & D Projects: A Process Model

N Prabhu Ganesh

Technology institutions (TIs) traditionally rely on industry for funding basic research, generating researchable problems and commercializing their R&D, while industrial firms traditionally rely on TIs for basic research and solutions to problems beyond their R&D capabilities. Intense firm – TI interactions in joint R&D projects also lead to both anticipated and unanticipated knowledge building and transfer across participating organizations which widen the scope of their technological and commercial activities. The type and scope of knowledge building depends on the mode of project process adopted. Synthesizing from several in depth project case studies, this paper proposes a typological theory based model, which traces the process of knowledge building in three identified ideal types of effective project process in industry – TI joint R&D projects, labeled Contracted Technology Development, Interactive Technology Transfer and Joint Technology Development. These models can enable practitioners in understanding and initiating effective knowledge development processes in such projects.

Industrial Restructuring Unions and the State: The Case of Textile Mill Workers in Ahmedabad City

Chowdhury Supriya Roy

This paper looks at the case of 50,000 odd workers who lost their jobs between 1983-84 as a result of closure of privately owned textile mills in Ahmedabad city. In a large majority of cases, these workers did not receive their due benefits or retrenchment compensation; and they remained outside the organized manufacturing sector, in situations of unstable self employment, as casual labourers, or as unemployed. The instrumentalities adopted by the Textile Labour Association (TLA) to get compensation or alternative employment projects, from the central government, for these workers exclusively to offer Voluntary Retirement Schemes to public sector employees. No comprehensive social security net has been devised for displaced workers in the private sector. The paper argues that despite India's democratic set up, a long tradition of trade union politics and a continuing labour-friendly rhetoric, state attention to the need for social safety nets even for the organized sector of the work force has been minimal. Shrinking employment in the organized manufacturing sector and the depletion of the bargaining space of trade unions have facilitated this process. Additionally, the TLA has not put forward the textile workers' case within the framework of a broad critique of the state's lack of attention to the need for social security and alternative employment in a context of industrial restructuring. The TLA is seen as characterized by an ageing leadership, heavily conciliatory methods of negotiations, and bound to an ideology of supporting rather than challenging the state. Working within these paradigms, the TLS appears to have been unable to identify instrumentalities of effective intervention called for a situation where neither the market nor the state have provided alternatives to the displaced workers. Caught between these forces, many thousands of displaced workers have been left outside of the framework of industrial restructuring.

Econometric Simulation of the Indian Silk

Naik Gopal and Singh S K

This study aims at understanding and quantifying the relationship between the important variables of the sub-sectors of the Indian silk industry through an econometric simulation model, and using the model for forecasting as well as policy simulations. Forecasts of the endogenous variables of the system (demand, supply and prices of mulberry cocoons, raw silk and silk fabric) was made for the period 1991-92 to 2000-01 which indicated that the growth in the industry will slow down in future. Policy simulations were undertaken to assess the changes in the import price of raw silk, export price of fabrics and regulation of the quantity of imports of raw silk on the silk industry. While imports and exports were closely linked, their impact on the silk industry was not very high. It was also revealed that the income of the consumers and mulberry acreage have significant influence on the industry.

A Comment on Nashs Independence of Irrelevant Alternatives Assumption for Choice Problems

Lahiri Somdeb

In a recent paper, Campbel (1994) shows that if a choice correspondence satisfies Arrow8217;s choice axiom then it has a complete, reflexive and transitive rationalization, even if the domain does not include any set with fewer then m members, where m is a given positive integer. The purpose of this paper is to provide a simpler proof (than the one provided by Campbell) of the same result when the choice correspondences are single – valued i.e., the case of choice functions. In such a situation Arrow's choice axiom is formally equivalent to Nash's Independence of Irrelevant Alternatives assumption.
