Some Implications of Structural Changes Within the Sample

Misra P N

An implicit assumption underlying least squares estimation procedure is that the unknown coefficients remain invariant over sample observations. In actual practice, however, one tends to use larger and larger number of observations without verifying as to whether this assumption holds true for the entire set of sample observations. Present article examines the consequence of ignoring this fact under the framework of a general linear regression model. We find that in the presence of parametric shift within the sample, the least squares estimators are biased as well as inefficient and that the explanatory power of the model is reduced. Theoretical findings are supported by empirical evidence.

Corporate Planning Practices in Private Sector Companies in India

Nambudiri C N S

This paper summarises the results of a study of corporate planning practices in private sector companies in India. Even though long term planning is not very widely practised by companies in the private sector, those companies which are practising it have developed some degree of sophistication in this direction. Planning in these companies is characterised by explicit statement of company's objectives and roles specific delineation of sectors for future growth, specific organisational responsibilities for scanning opportunities and detailed operational planning. While companies find many aspects of the plans and planning process as supportive to the process of corporate planning, they found that process of planning had not eliminated the uncertainties of economic policy. Firms have generally found that corporate planning within the framework of national economic planning is both feasible as well as rewarding: The long range goals of economic development presented by the plans is a sufficient justification to undertake long term corporate planning. The study reveals both the uncertainties arising from government regulated as well as the certainties that such revelations provide to companies. In general, the study points to the importance of government and the objectives of national economic development programmes as a significant area for attention of planners.
