Post - Production System: Himachal Apples

Girja Sharan and Kayastha Sandeep

A dynamic continuous mathematical model for post-production system of Himachal apples has been made. The model includes all operations from harvesting to arrival in the wholesale market at Delhi. Beta density function appears appropriate to define harvesting schedule that drives the model. Parameters used in the model are built on the basis of insights gained from published literature and discussions with the officials handling Himachal apples. The model is capable of indicating in advance the resource requirement (labour, trucks, boxes etc) at any or all nodal points in the post-production phase. It can readily show the effect of constraint on any of the resources. At present APMC market, Delhi is the only source of definitive statistics on apples. The model is therefore tested against data from the records of APMC for the season of 1987. In particular, the arrivals in Delhi as computed from the model and as recorded by APMC are compared. The form of curve resulting from computations and that of the actual are similar. When realistic constraint of shortage of trucks (inferred from APMC data) is imposed, besides the form, magnitudes of arrivals also come close. Thus, the model appears satisfactory. The model can be useful to large orchardists, cooperatives or other corporate bodies. It can also be useful to forwarding agents, cold storage facility owners and the APMC market. Design engineers working on mechanization of harvest, grading and handling will also find it useful.

Development of a Psychometric Measure of Learned Helplessness (LH)

Pestonjee D M and Reddy Prathap

Behavioural sciences have constantly attempted to bring greater rigour in their measurements. Tests and instruments represent one such attempt. The aim of the present research is to evolve and develop a scientific tool for measurement of the 'learned helplessness' (LH) concept. The authors have taken into account such attributions as: internal-external, stable-unstable, and global-specific. With the help of factor-analysis, eight of factors have been extracted and a 24-item scale on LH has been standardised.

Input-Output Tables for Kerala Methodology and Estimates

Ravindra H. Dholakia and Dholakia Bakul H

Input coefficient matrix and input transaction matrix for Kerala State are estimated in the present paper for 50 x 50 commodity sectors for the year 1984-85 at current prices. The sectors and methodology followed here are compatible and consistent with those of the national I-O tables which form the basis for the 7th Five Year Plan. The Kerala I-O matrices are estimated using both the survey based and non-survey based methods. Comparison of the estimates based on both these methods reveals that non-survey based method used in the paper performs satisfactorily to capture the overall regional differences from the national technology. If, however, the purpose is to capture sector-activity-specific differences in the regional technology, the survey based method should be preferred over the non-survey based method although the former involves much greater time and effort.

Am Empirical Study of the Intertemporal Relations Among the Regional Share Price Indicators

Bhat Ramesh

The purpose of the present research effort is to examine the intertemporal relationships among the share price indictors of five regional stock exchanges at Bombay, Calcutta, Madras, Ahmedabad and Delhi. For each regional share price index the monthly charges, both absolute and percentage, are complied and correlated with each other and all-India index over the time period March 1971 to June 1985. The lag of each regional price relative has been regressed against the lag of all-India price relative with its lead and lag variables. Finally, an attempt has been made to examine the inter-regional relationships among the five indicators by using the recursive regression method.

A Study of Role Stresses in Top and Middle Management

Pestonjee D M

In the present study, attempt is made to explore the types of role stresses experienced by top and middle management personnel and to establish the degree of relationship among these role stress variables. 'ORS Scale' developed and standardized by Pareek (1983) was administered on a sample of 221 top managers and 326 middle managers. This scale measures ten types of role stresses as well as overall role stress. Critical ratio test, median test and Pearson's product moment coefficients of correlation were used to analyse the data. Findings of the study revealed that Middle managers (MMG) scored significantly higher on interrole distance, personal inadequacy, self-role distance and resource inadequacy. Role expectation conflict, role ambiguity and overall role stress were also found to be significantly higher in case of middle managers (MMG) as compared to top managers (TMG). Out of 55 coefficients of correlation among role stress factors, 53 for top managers and 51 for middle managers emerged as statistically significant. In the light of findings, implications of the study are also discussed.

Market-Wide Commonalities in Corporate Earnings and Significance Tests of Accounting Beta

Bhat Ramesh

The annual earnings performance of a company reflect numerous events. Some of these events affect almost all the companies in the economy whereas some are specific to the industry in which the company is operating. The objective of the present paper is to discern and quantify the influences arising primarily because of economy-wide factors. They are referred as market-wide commonalities in corporate earnings. This has been done by using the market model framework. The study uses a sample of 182 companies from the population of companies listed on the Bombay Stock Exchange The earnings and book rate of return series of 17 years for each company is used to construct the market index. The accounting earnings beta estimates are obtained for each company by using OLS method. The market model has been tested in its various forms. The model consistent with OLS specification has been considered to be more relevant in interpreting the results. The hypothesis that there is a systematic index does not find empirical support. The explanatory power of the models consistent with OLS assumptions has been found to be very low.

Economy Demand Factor in Regional Industrialization

Ravindra H. Dholakia and Bhat Ramesh

In the present study it is argued that policies to achieve reduction in regional inequalities in industrialization in India so far have been guided by theories emphasizing the role of supplies of factors of production, particularly capital stock. This has resulted in only increasing the incremental capital-output ratios rather than achieving the desired reduction in the regional inequalities. The present study advocates policies based on theory emphasizing the role of national demand factors. It discusses critically the earlier studies attempting to test the role of demand factors in determining the extent of regional industrialization and suggests a more acceptable specification of the model for testing the hypothesis. State is taken as the regional unit and time series data on SDP are used for empirically testing the hypothesis. Indian regional data seem to support the hypothesis of national demand factor playing a major role in determining the extent of regional industrialization.

Financing Public Enterprise in India: The Case of Central Government Enterprises

Gupta Anand P

This paper provides a perspective on how Central Public Enterprises' plan investments are financed. It reveals that although budgetary support continues to be a major source of financing Central Public Enterprises' plan investments, its contribution has declined from 53% in 1984/85 to 46.9% in 1986/87 and is expected to decline further to 40.3% in 1987/88. As per cent of GDP, budgetary support for CPEs' plan investments has declined from 2.83% in 1984/85 to 2.66% in 1986/87 and is expected to decline further to 2.18% in 1987/88. There is reason to believe that this trend would continue. Significantly, while budgetary support for CPEs' plan investments is declining, Government of India's budget deficit continues to be high-it is expected to be about 8.5% of GDP in 1987/88 against 7.8% in 1984/85. Indeed, the 1987/88 deficit would have been 9% of GDP, not 8.5%, had the GOI not changed the accounting treatment of oil surplus funds. (These funds amounted to at least Rs. 35 billion during 1982/83-1085/86 and were shown in the GOI's books as interest-bearing capital receipts from the Oil Coordination Committee. The GOI has now decided to treat most of these surplus funds as a current contribution from the OCC. The contribution amounted to Rs. 13 billion in 1986/87 and is expected to be Rs. 17 billion in 1987/88.) What all this boils down to is that it is the rapid growth in GOI's disbursements other than budgetary support to finance its enterprises' plan investments, which is responsible for the rising budget deficit. This is an important point, given the general tendency of many commentators to attribute the recent rises in GOI's budget deficits to its budgetary support to CPEs to enable them to finance their plan investments. Clearly, a strategy to control the GOI's rapidly rising expenditures urgently needs to be developed. There is also a strong case for determined efforts to improve the financial performance of CPEs. The paper shows that net return on net worth employed in CPEs is pitifully low-4.5% in 1986/87, the latest year for which the relevant data are available. This is substantially less than even the artificially low interest rates which the GOI pays on the resources it borrows. What is more, even the above overall net return is largely because of the petroleum enterprises, which accounted for nearly three-fourths of the net profits of profit-making CPEs. Indeed, as the net profits of non-petroleum CPEs were inadequate to offset the losses of loss-making CPEs the net return in the non-petroleum sector was in the negative - -1.2%. Clearly, this is not a happy situation.

An Exploratory Study of Key Performance Areas and Competency Requirements of Young Management Graduates

T. V. Rao and Solanki Pramod K S

The study aimed at exploring the nature of activities and tasks performed by young management graduates and the skills (human, technical and conceptual) required to perform them effectively. Forty four management graduates from 34 organizations (private sector, public sector and multinational companies, banks, family-owned business and professionally-managed organizations etc) were interviewed for the study. Analysis of the interview data has yielded the following: 1. A comprehensive list of key performance areas and competency requirements for marketing, finance, production, personnel and systems jobs in different settings. Though the performance areas show tremendous variation across different jobs, the following competencies have been stated to be indispensable for effective performance of any job: Man-management skills, innovativeness and ability to plan and execute diverse activities. 2. Certain issues which have significant implications for improving the quality of management education in India. Most important of them is faulty curriculum. A large number of readings and cases being used are written by foreign authors based on Western settings. These have limited relevance to the realities of Indian organizations. Consequently a fresh management graduate is not well prepared to meet the challenges of work life. The case discussion and exercises conducted in the class hinge around the role of Chief Executive in the organization. This gives rise to false expectations among students. They expect to do the kind of things i.e. policy planning and strategic decision-making, which in reality may come to them only in the later years of their career. In order to avoid this rude shock and frustration to the graduates, more and more Indian cases and readings highlighting work life of lower and middle level executives should be incorporated in the curriculum. 3. Recommendations for future management graduates to help them adjust to the work environment during the formative years. They have been advised to rely on the feedback from their seniors, rather than on placement talks, while making the choice of job and organization; more weightage should be given to the job content rather than the salary at this stage; they should not have "MBA hang ups" and mix freely with people as interpersonal skill is the most important ability for effective performance on any job.

Inter-Industry Tables for Gujarat: Methodology and Estimates

Dholakia Bakul H and Ravindra H. Dholakia

Regional Input-Output tables compatible with the national input-output table can play a crucial role in formulating realistic regional plans and also in ensuring that the spatial dimension is properly incorporated into the national planning model in a large sized multi-region economy like India. The regional I/O table captures the basic differences between the state economy and the national economy in terms of the production structure and technology. An attempt has been made in the present paper to construct the input-output table for Gujarat compatible and consistent with the national I/O table for 1984-85, which formed the basis for the national 7th Five Year Plan. Accordingly, the I/O table prepared for Gujarat consists of 50 sectors and represents commodity flows at current (1984-85) prices. Both the input-output coefficient matrix as well as the input transactions matrix have been presented in the paper. There are two alternative methods for constructing regional I/O tables: The survey-based method and the Non-survey based method. The latter involves regionalising the national I/O matrix. The paper presents both sets of estimates for Gujarat for the year 1984-85. A detailed comparison of the results indicates that if the purpose of constructing regional I/O table is to capture sector-activity-specific differences in the regional technology, the survey-based method should be given priority over the non-survey based method, although the former involves much greater time and effort.
