The Importance Of Public Sector Undertakings Economics Essay

ABSTRACT Public sector undertakings (PSUs) are considered to be vital and crucial pillars for strengthening country’s economy. The prime purpose of starting public sector enterprises was to fabricate infrastructure for economic growth and economic development. Since their birth PSUs have played an essential role in achieving the goal of economic development. Various factors such as deterioration of financial performance of PSUs, rising fiscal deficit forced Government to adopt a radically new approach towards the working of PSUs. The policy measure implemented involved Disinvestment of public sector undertakings (PSUs) .During the regime of P.V Narasimha Rao, entire new economic policy of Liberalisation, Privatisation, and Globalisation (LPG) was introduced in India in the year 1991.Dr Manmohan Singh was the finance minister who successfully implemented the policy of Liberalisation, Privatisation, Globalisation (LPG) into India. The goal of Disinvestment policy was as follows:
Improving the financial performance of PSUs.
Generating resources to reduce the fiscal deficit.
Promoting extensive public participation (including employees).
INTRODUCTION Public sector undertakings (PSUs) are the companies established, maintained and controlled by the Central Government of India having 100% stake in it. In 1947 when India became independent, the country was confronting with a variety of socio-economic concerns which had to be resolved. India was mainly agriculture dependent economy with poor infrastructure facilities, no knowledge about investment, pathetic industrial base and low level of savings. There was wide difference in incomes of different people. The private sector neither had the necessary resources, trained managerial staff nor the ability to undertake risks involved in long term projects which forced the state government to intervene in all the sectors of economy. The type of problems faced by the country in all domains including economical, social obliged the Government of India to focus on public sector enterprises (PSEs) to empower self -dependent economic development. The holistic outline of public sector undertakings in India is heterogeneous mixture of service industries, manufacturing industries and infrastructural industries.
The basic objectives of starting public sector enterprises in India were as follows:
Generate employment opportunities.
Reduce gap between incomes of different people by redistribution of wages.
Promote rapid economic growth.
Improve essential infrastructure for economic development.
Support development of small and medium size enterprises (SMEs).
Central public sector units are widely diversified in products and services from steel manufacturing, instruments and machine tools, road transport, power generation, mineral mining, coal mining, manufacture of heavy machines, telecommunication equipment, equipments for thermal power station. Over the last five decades, huge investments have been done in public sector enterprises to expand their production, employ new emerging technologies. As on 31st March, 2005 there were 237 central public sector undertakings out of which 10 fall under the category of enterprise under construction, 144 are from field of manufacturing/producing goods and 83 under the head of enterprises providing services. From the Table-1 it is evident that initially at the commencement of First Five Year Plan, only Rs.29 crore was the total investment for 5 enterprises. After gradually increasing the budget, at the commencement of Fifth Five Year Plan, the total investment reached whooping Rs.6237 crore and the number of units became 122.By the end of the fifth Five year plan, total investment touched Rs.15534 crore and the number of enterprises reached 169.From the data, it is quite clear that there has been increasing trend of investment from the commencement till the end of fifth five year plan, a rise of 149.06 % is observed. Similarly a hike of 57.70% in investment was examined from the start till the end of eighth five year plan. The investment made in public sector in 2005 was Rs.3, 57,849 ,an increase of 2.24 % from 2004.It can thus be concluded that there is increasing tendency towards investment made in the different five year plan.
TABLE 1:
DISINVESTMENT The dictionary meaning of word “disinvestment” is opposite of investment. Investment means putting money into something with the hope to generate profits from it. So disinvestment means to pull out money from the investment. Initially central government had 100% stake in all the public sector enterprises, but due increasing fiscal deficit government is forced to sell 5 or 10 % stake to the public, thereby generating income for government spending. This way the government is losing full control over the corporations, but has no other option. Many times the government finds it very difficult to fulfil all the financial obligations of public sector enterprises, hence undergoes rigorous resource crisis. To bring back country’s economy on right path, disinvestment formed an important part of structural reforms carried on by the government. The two most important reasons which favour disinvestment are as under:
Offer financial support to public sector undertakings (PSUs).
Develop effectiveness

Factors That Affect Residential Demand For Electricity Economics Essay

In this chapter the methodology of the research is going to be discussed. The chapter is going to focus on the framework of analysis, in which the variables are discussed in detail. In this chapter the research hypotheses are also stated. The elements of research design will focus on the type of research, how it will be carried or what type of data will be used and it forms an integral part of the chapter. This chapter will pay a special attention to data used in the research; the chapter discusses the source of data and any limitations regarding the collection or use of data. The chapter ends with a discussion of how the data will be used to make regressions and how the regression will be interpreted.
Framework of Analysis The paper attempts to study the main factors that affect residential demand for electricity; this is to try and balance the supply of electricity with the fast growing demand in the economy. The electricity crisis is a growing concern for the country. This is reflected in the theoretical framework. The dependant variable considered is the consumption of electricity in the residential sector. The demand of electricity in this sector, as shown by the literature, is dependent on factors such as price of electricity, income of people, price of substitutes, price of electrical appliance and the number of electricity connections. Here it is important to note that this research uses consumption of electricity and not demand of electricity. In Pakistan there are other factors which affect the consumption of electricity such as worker remittances from abroad and generation of electricity; as there is a shortage of electricity one can only consume what is made available by the grid.
One of the most important factors effecting electricity consumption like most other goods is its price. Hence this study will be trying to analyze the impact of any price change on consumption of electricity. It is proposed that the price elasticity of demand for residential electricity is found otherwise a simple linear relationship is also acceptable. This will help us anticipate the responsiveness of domestic demand for electricity to a change in price; helping us make decisions on any policy regarding price changes.
The impact of income on electricity consumption is of paramount importance. The importance of this variable lies in its ability to predict future demand of electricity. It is very easy to find forecasts for national income of countries hence income elasticity of demand is going to help us estimate future demand for electricity. Again it would be preferred if the income elasticity of demand is calculated, whereas if this is not possible only a linear relation too is quite useful.
Then we have important variables such as price of natural gas and price of electrical appliances. The significance of these variables derives from the fact that natural gas is a substitute to electricity and appliances are complimentary goods. So the demand for natural gas or electrical appliances will affect the consumption of electricity directly. The higher the demand for electrical appliances, the higher will be the demand for electricity. A higher demand for natural gas will result in a lower demand for electricity. Knowing price has an inverse relation with normal good’s demand the price of natural gas has been hypothesized to have a positive relation with demand of electricity. The price of electrical appliances however, is going to have a negative impact on electricity consumption.
Over the years the government has been trying to improve infrastructure all across the country, this has resulted in the electrification of many villages. A growing population in the cities means new houses being built and electricity connections demanded. The growing number of electricity connections is going to increase the household consumption of electricity. Hence the effect of growing electricity connections is included in our study, through the variable electricity connections.
The generation of electricity as already discussed will be an important variable in determining consumption of electricity. This is because no matter how high is the demand for electricity one can only consume if electricity is supplied. Also the worker remittances form a big portion of income for people in Pakistan. This raises the living standards for the beneficiaries and increases the demand of all goods including electrical appliances and electricity.

Elements of Research Design 3.3.1 Type of research My research is applied research as questions are asked about a specific problem; that is controlling electricity consumption by households. The research is done with the attention to apply the results of the findings to solve the electricity crisis.
3.3.2 Study Settings The research is conducted under non-contrived settings.
3.3.3 Nature of Data The data used in this research is going to be of time series in nature. The data will be gathered from WDI and government and private reports. The data used will be gathered for the latest 20 year that is available.
3.3.4 Unit of Analysis The unit of analysis used for the purpose of the study is sectoral in nature and is about Pakistan
3.3.5 Reference Period The reference period preferably is 1980 to 2009. It is this time period when Pakistan has started facing chronic problems of electricity shortage.
Data Collection Preferences The nature of data to be used was secondary; hence the data could have been calculated through numerous sources. Care has been taken that the data is collected by the best source possible and that it is as consistent as possible.
To collect data for the dependant variable, the consumption of electricity by household sector, the Economic Survey of Pakistan has been chosen. The data could have been collected from sources like WAPDA’s data bases and from the world development index (WDI). The data found in WDI was not separated into sectors, hence this option was ruled out.
The data for price of electricity was available in different sources like the Private Power and Infrastructure Board (PPIB) website, the economic survey of Pakistan and electricity bills. The problem with electricity bills was that they were monthly bills and had to be accumulated and averaged to find yearly values. Also there were inconsistencies regarding the tariff structure of Pakistan as already discussed. Whereas the data provided in Economic Survey of Pakistan is in the form of indexes and hence consistent. So it will be useful to use Economic Survey of Pakistan values.
Similarly the data for natural gas prices was easily available from OGRA reports, from Sui Northern Gas Pipelines Limited (SNGPL) prices, and from the Economic Survey of Pakistan. Natural gas before the year 2000 was stated in volume consumed, after that the energy equivalent is used as the unit for pricing Natural Gas. Again the Economic Survey of Pakistan is the best and most consistent source with data stated in price indexes.
The data for variables like electricity generated, worker remittances and per capita income WDI, is preferred over other sources this is because of its world wide appeal as a reasonably correct source of data. Also because in other sources although data is easily available on these variables but it is either not complete or has the problem of being inconsistent. For example the data on electricity generated was not available as a total value but a lot of summation is required to get to the final total generation value. Also data is not available in other sources from as early as 1980.
Data Collection and related procedures The data on most variables was easily available from 1980 to 2009, also this time frame easily covered two eras of energy crisis the early 1990s and the late 2000s. The data for the dependant variable, the consumption of electricity by household sector, was collected from the source that was preferred, that is the Economic Survey of Pakistan. This data was in the form of 1000s GWh. To use it the data was converted to GWh by simply multiplying by 1000. The only problem was that the data was only available from 1988. The values for first eight years had to be interpolated. This was done by using Minitab; the mathematical form used to interpolate data was T6. This was found to be the best fit for existing values hence the predicted values were generated using this approach.
Electricity connections were again collected from the Economic Survey of Pakistan. This is because this data was not available in WDI and there was a minimum data available in WAPDAs sources.
The price of electricity and the price of natural gas both have been collected from the Economic Survey of Pakistan. These values have been collected in the form of indexes as there were inconsistencies involved in actual price data. These inconsistencies included changing of scientific unit in case of natural gas and changing of tariff tiers in case of electricity.
The data on complimentary goods that is electrical appliances was searched thoroughly. While searching, the criteria set for any option was it should not have changed much in the last 30 years also the data for as long a time period as possible is available. Price of 60 watt light bulb was chosen as its technology has not changed by much and its prices were known from 1986 onwards. The rest of the prices were interpolated using the function of T10.
Both per capita income and worker remittances have been taken from WDI. This source had a complete record of data over these years hence there was no need to find any other source for the data of these variables.
