Government Budget - Reduction in inequalities of income through quota system

Class 12 Macro EconomicsChapter Government BudgetTopic Objectives of BudgetSub topic -How to reduce inequalities of income

It is the most important question in the exam moving beyond the book I feel that we can emphasize  on the recent quota system which has been fixed by the government for socially backward category

Method to reduce inequality of income

The union cabinet decision to push for 10 percent reservation and educational institutions for the economically backward section in the general category is a significant move

The move is welcome as the new category of reservation will be targeted at the economically deprived in the general category, which does not benefit from any form of job quotas at present

It also does not differentiate on the basis of caste and religion

The reservation is not just for the hindus but also for the non - hindus such as muslims and Christians

The eligibility criteria for ‘economic weakness’ has been drawn up in such a way that it appears to cover almost all Indians.

The annual family income should not exceed Rs8 lakh.

 The maximum area of agricultural landownership is not to be above 5 acres. The area of house should not be larger than 1,000 sq ft.

 Some of these criteria are sufficiently liberal to accommodate almost 95% of Indian households.

 The country as a whole is still poor, with economic strength concentrated in the hands of a few. Also, criteria that apply to about 90% of the population being the basis for reservation for 10% is patently absurd.

Besides, the public sector has long vacated the commanding heights of the Indian economy and generated fewer and fewer employment over the recent past.

 In concrete terms, it means the number of jobs on offer will be pitifully small, and competition for them even more incredibly fierce than it already is.

The government jobs sector is simply not big enough to pick up the slack

While promoting reservations in private colleges, an extension of the Right to Education, is indeed a positive move, the key issue here is the quality of instruction imparted and the price charged for it.

Despite the challenge of creating a skilled and intelligent population, education spend (Centre and States) as a share of the GDP has actually fallen from 3.1 per cent of the GDP in 2012-13 to 2.7 per cent in 2017-18.

Production Possibility Curve - An Application

Application of Production Possibility Curve

Class 11 and Class 12

Micro Economics

Rapid ride: From Sarai Kale Khan to Aerocity in about 15 minutes

While Delhi Metro connects Gurgaon to the capital, many industrial towns beyond Gurgaon, which have been witnessing a growth in housing too, don’t have a fast and convenient mode of connecting transport. The RRTS corridor is expected fill this vacuum.

“Once these lines become operational, commuting to major points, such as the airport, will become easier. For instance, the Delhi-Gurgaon SNB link will originate at Sarai Kale Khan and reach Aerocity within 15 minutes. 

Similarly, travelling from Aerocity to Rajiv Chowk in Gurgaon will take 15 minutes,” said Sudhir Kumar Sharma, CPRO, NCRTC. “Older Gurgaon will be connected with this high-speed network and people can reach the airport in 10 minutes,” he said.

The above news article was published in the Times of India and it talks about the development of infrastructure

Explain how will it affect the Production Possibility Curve

Answer

As their is development of infrastructure ( transport ) it will help to develop employment opportunities in the way of labour mobility so we will move from inefficient use of resources to efficient use of resources 

As shown in the diagram we will move from point E inside the PPC to any point on the PPC
