A queueing problem with batch arrivals and correlated departures

Summary This paper considers the steady state behaviour of a queueing system in which (i) the input following the Hypergeometric Distribution is in batches of variable size (ii) queue discipline is first come first served it being assumed that the batches are preordered for service purposes and (ii) the service at two consecutive time marks is correlated. Probability generating functions for the various cases have been obtained and the mean queue lengths derived.     

Dynamic effects of externalities,optimal saving and economic growth

Conclusion Recognizing the fact that provision of mixed public goods can result in both consumption externalities of the Samuelsonian variety as well as production externalities we set out to extend the earlier results of Rao and Kalpagam (1977) on the effect of public goods on economic growth. In so doing, we considered three standard specifications of production externalities and enlarged the concept of consumption displacement. Our basic conclusion is that the results of our earlier paper remain valid under the more general conditions set out in this paper.

Mixed public goods,consumption externality,and economic growth

Conclusion From the viewpoint of pure theory the basic contribution of this paper is in identifying both the consumption inducing and consumption displacing tendencies when mixed public goods are financed by income taxes. We have come to recognize that the provision of mixed public goods is conducive to economic growth if they are consumption displacing in nature.     

OCCUPATIONS CHOSEN BY THE SONS OF FARMERS

The Government aims to reduce the number of farmers in this country by encouraging some existing operators to retire. This paper explores an alternative possibility, namely, that of influencing potential new entrants, the majority of whom are farmers' sons. For a number of reasons, sons of existing farmers may find it easier, on leaving school, to stay in agricirlture than to enter other occupations. Later realisation by many of them of the economic prospects and subsequent moves to other jobs represent a waste of human resources to the whole economy as well as causing social hardship to the individual. A recent survey of the occupational choice process of rural schoolboys and students aimed to discover the obstacles, if any, to greater outward mobility. Farmers' sons were compared with others in respect of educational and occupational aspirations, alternative jobs considered, sources of career advice and work values. Some ways are suggested whereby sons whose fathers have farms which are too small to provide a living might be made aware of their own prospects in farming, the range of opportunities open to them and the satisfactions to be gained in other occupations before they commit themselves to an unrewarding strirggle in farming.     

Training and industrial relations—a broader perspective

An analysis of the assumptions underlying the traditional approaches to training demonstrates their inadequacy when it comes to the development of training in an industrial relations context. By taking a broader approach, however, suitable training strategies and methods can be developed.     

On a certain type of priority queueing problem

This paper studies the transient behaviour of a queueing problem in which two type of units form queuesQ ₁ andQ ₂ before a single server. The units ofQ ₁ are considered first for service. As soon as there are no units ofQ ₁ in the system, a batch ofm units fromQ ₂ or the whole queue length shifts toQ ₁ and are served. Probability generating functions for the queue lengths for the two cases have been obtained.
