Group Decision Theory and Production Planning Problems

Lahiri Somdeb

In the present work it is argued that a group decision problem can be viewed as a problem in output choice of a regulated firm and conversely. Having developed the above isomorphism, we turn to a related problem: that of characterizing solutions to production planning problems which are non-decreasing in the cost constraint. Such solutions are called monotone solutions. We establish in this paper that monotone solutions to production planning problems are essentially continuous functions of the cost constraint.

Fix Price Equilibria in Distribution Economies

Lahiri Somdeb

In this paper we consider a distribution economy which is dictated by the conditions of the non-substitution theorem for linear economic models of production. Although flexible prices in the consumption section are perfectly compatible with the conclusions of the non-substitution theorem, rigid prices are likely if the production sector has sufficient say over the economy. We study some existence and efficiency properties of fixed-price equilibrium in distribution economies. Subsequently, we turn to an economy with a produced public good and show that all voluntary and efficient allocations for such an economy must be ratio equilibrium allocation, thus establishing the inherent non-optimality of rationing schemes in mixed economies. It is observed that the case for a distribution economy rests solely on the assumption of a numeraire good in terms of which all value and costs can be measured, whereas the general validity of the non-substitution theorem (and thus of uniquely defined fixed prices arising out of the production sector) depends on additional mathematical structure of the cost function. Thus, if the underlying conditions of production invalidate the non-substitution theorem, fixed prices can be considered as a policy instrument available to a social planner in order to implement a desired distribution of resources in the consumption sector.

ISO 9000 Linked Tax Incentive: A Better Leverage Point for Growth

Ragunathan V and Sebastian Morris

The efficiency and efficacy of government instruments in implementing policy have been particularly problematic in India. For instance, the incentives, mostly fiscal, to boost been linked to investments, e.g., development rebate and later investment rebate; others have been linked to depreciation like higher depreciation rates for certain categories of plant and machinery; yet a host of other incentives have been in the form of various subsidies pertaining to backward areas and free trade zones; and various duty drawbacks and value based export licensing and so forth. Many of these systems of incentives have long since become dysfunctional, while others are still in force, but surprisingly there has never been any incentive linked to quality, when it is quality which may be regarded as the single most important and fundamental hindrance to our exports and industrial growth. Given the image of shoddiness usually associated with Indian products, for international buyers, the ISO 9000 series becomes vitally necessary in lowering the perceived risk in dealing with a newcomer in the international market. In this context, we suggest linking tax incentives to quality via ISO 9000. Such an incentive system, we argue, among other benefits will strike at a pivotal leverage point for change given the present situation and the overall thrust of economic policy in opening up the economy to speed up exports.

New Product Introduction Strategy in Consumer Products Category in India

Abraham Koshy

The objective of this study is to obtain an insight into the nature of new product introduction strategies of Indian nature of new product introduction strategies of Indian organizations. Data on 237 product/brand launches were collected from information published in four business periodicals between January 1991 and July 1993. The study indicates that there are no significant differences between multinational corporations (MNCs), large, medium and small enterprises as far as propensity to introduce new products is concerned. But a higher proportion of MNCs and large enterprises tends to follow multi-product/brand strategies as opposed to a tendency to follow single product/brand strategy by small enterprises, and to a lesser degree, by medium enterprises. MNCs tend to depend heavily on brand/line extensions and to a lesser extent on new brand strategy; but they appear to be less aggressive in entering new lines through new product introductions. By and large, the strategies of large organizations resemble that of MNCs, though, on a comparative basis, they show lesser dependence on brand/line extensions and a higher emphasis on new brand strategy. New product strategies of medium enterprises fall between that of larger organizations and smaller enterprises. Small scale enterprises show an almost equal propensity to introduce products as MNCs, large and medium enterprises. The inability of the small enterprises to capitalize on equities of mega brands is compensated by aggressive new brand and new product strategies. In fact, small firms account for the highest proportion of new products that are introduced and this ability to venture into uncharted territories emerges as their greatest strength.

Existence of Equilibrated States in Multi-Criteria Decision Making Problems

Lahiri Somdeb

My interest in multi-criteria decision making is mainly due to my interactions with my colleague Professor P.R.Shukla. I have had the benefit of many useful discussions on this topic with Professor Prakash Abad, as well. The application of multi-criteria decision making studied in this paper, is in line with my current research interests, for which I would like to thank amongst others Professor J. Jordan.

Indian Manufacturing Industry: The Growth Episode of the Eighties

Sengupta D N

Growth of Indian manufacturing in the 80s was market-driven: policy changes enabled an expansion in output in response to growth in demand. Output growth led to productivity increase which came from material and labor savings, in that order of importance. Ten percent of the productivity increase was retained as increased profits and the rest reflected in falling prices (in relation to overall prices). This further stimulated demand. There were some structural changes, like growth of the factory sector at the expense of the cottage sector and an increase in the industrial sector's ability to sustain its own growth. Industrial growth in itself did not worsen the b.o.p. situation. In fact, the balance of commodity trade improved, because output growth led to export growth which outpaced import growth. However, the relatively slow growth in imports was the result of Bombay High and may not be sustainable. Future strategy for industrial development should pursue growth and not multiple objectives. Other desirable outcomes would follow. Growth is most likely to be achieved by explicating the existing demand for consumer goods. This will pull up the demand for intermediate and capital goods also. Both industry and government should depend on volume growth for profits and revenues and keep prices and indirect taxes low. This is possible with continuous increases in productivity. Policies that expand markets, increase competition, promote technical progress, encourage human resources development and stimulate industrial investment will also increase productivity. A cautious view on imports seems advisable.

A Study of Organizational Climate in Relation to Organizational Role Stress (ORS) and Learned Helplessness (LH)

Pestonjee D M and Desai Tripati Pande

The purpose of the study is to investigate the relationship between the factors of learned helplessness (LH) and organizational role stress (ORS) to the motivational climate of the organization. The sample comprised of two hundred and twenty respondents belonging to the middle management of five units of the engineering industry located in western India. Motivational Climate of the organization is analyzed by using MAO-C questionnaire (Pareek 1981) comprising of 60 statements employing twelve dimensions and six motives of the organization. Organizational Role Stress scale (Pareek 1981) is used to measure the stress the individual feels in the organization. It is a five point scale wherein 10 dimensions of stress are measured. Learned Helplessness scale (Pestonjee and Reddy, 1988) consisting of 24 items with a six-point rating format, is used to measure learned helplessness. Means and S.D.'s intercorrelations and regressions are used to interpret the data. From the results, we observe that Role Erosion was the highest contributor of stress in this group. The climate of the organization that is related to the trust among various members and groups seems to significantly affect the learned helplessness and stress of the executives. 'Management of rewards' was the other dimension of organizational climate which had a significant bearing on the dependent variables of learned helplessness (LH) and organizational role stress (ORS).

Arima Model for and Forecasts on Tea Production in India

Gupta G S

The paper explains the autoregressive integrated moving average (ARIMA) (Box-Jenkins) model in detail, develops an ARIMA model for tea production in India using monthly data for the period Jan. 1979 through July 1991, and applies the so developed model to forecast tea production during the future 12 months. On verification through several statistical techniques including the accuracy of sample period forecasts, the model is found to be quite strong. The post sample period forecasts are consistent with the seasonal pattern of the data in past 12 years and this enhances the model's credibility. As per the results, tea production in India during the post-sample one year is expected to be fluctuating between a low of 14,300 tonnes during Feb.-March 1992 to 90,600 tonnes in July 1992; the actual data for these periods are not yet available in published form.

Review of the Policy Changes in the Indian Telecom Sector: Implications for Decision Makers

Rekha Jain

In response to the business needs of faster, cheaper, and more varied modes of communication, the telecommunication sector in many countries has been undergoing rapid technological and structural changes over the past few years. Since the mid 80s, the telecommunication sector in India, too, has undergone major transformations. Private participation in the manufacture of end user equipment and services, reorganization of the monolithic Department of Telecommunication, and raising finances from the public for investment in the state owned factories and organizations have been some of the policy initiatives of the government. In a scenario where the features of the Indian telecom sector such as under-investment, amalgamation of regulatory and operational functions, ill-defined sector policies, and lack of financial and administrative autonomy are common to many other developing countries, the consequences of sectoral changes have implications both for decision makers at the national level as well as in other developing countries. This paper attempts to critically review the policy changes initiated by the government and draw lessons from them.
