0.50 & 0.30 \\
0.41 & 0.33
\end{array}\right]\). Test whether the system is viable as per Hawkins Simon conditions.
Solution:
Technology matrix B = \(\left[\begin{array}{cc}
0.50 & 0.30 \\
0.41 & 0.33
\end{array}\right]\)
I – B = \(\left[\begin{array}{ll}
1 & 0 \\
0 & 1
\end{array}\right]-\left[\begin{array}{ll}
0.50 & 0.30 \\
0.41 & 0.33
\end{array}\right]\)
= \(\left[\begin{array}{rr}
0.50 & -0.30 \\
-0.41 & 0.67
\end{array}\right]\), the main diagonal elements are positive.
|I – B| = \(\left[\begin{array}{rr}
0.50 & -0.30 \\
-0.41 & 0.67
\end{array}\right]\)
= 0.335 – 0.123
= 0.212, positive

0.6 & 0.9 \\
0.20 & 0.80
\end{array}\right]\). Test whether the system is viable as per Hawkins-Simon conditions.
Solution:
Technology matrix B = \(\left[\begin{array}{cc}
0.60 & 0.9 \\
0.20 & 0.80
\end{array}\right]\)
I – B = \(\left[\begin{array}{ll}

0 & 1
\end{array}\right]-\left[\begin{array}{cc}
0.60 & 0.9 \\
0.20 & 0.80
\end{array}\right]\)
= \(\left[\begin{array}{rr}
0.4 & -0.9 \\
-0.20 & 0.20
\end{array}\right]\), the main diagonal elements are positive.
|I – B| = \(\left|\begin{array}{rr}
0.4 & -0.9 \\
-0.20 & 0.20
\end{array}\right|\)
= 0.4 × 0.20 – (-0.20) × (-0.9)
= 0.08 – 0.18
= -0.1, negative
Since |I – B| is negative one of the Hawkins-Simon condition is not satisfied. Therefore, the given system is not viable.

Question 3.

0 & 1
\end{array}\right]-\left[\begin{array}{cc}
0.50 & 0.25 \\
0.40 & 0.67
\end{array}\right]\)
= \(\left[\begin{array}{rr}
0.50 & -0.25 \\
-0.40 & 0.33
\end{array}\right]\), the main diagonal elements are positive.
|I – B| = \(\left|\begin{array}{rr}
0.50 & -0.25 \\
-0.40 & 0.33
\end{array}\right|\)
= (0.50) (0.33) – (-0.40) (-0.25)
= 0.165 – 0.1
= 0.065 (positive)
Since the main diagonal elements of I – B are positive and |I – B| is positive, Hawkins-Simon conditions are satisfied. Therefore, the given system is viable.

Question 2.
Solve for x quantity demanded if 16x – 4 = 68 + 7x?
Answer:
16x – 4 = 68 + 7x
16x – 7x = 68 + 4
9x = 72
x = \(\frac{72}{9}\) = 8
∴ x = 8

Question 3.
A firm has the revenue function R = 600q – 0.03q2 and the cost function is C = 150q + 60,000, where q is the number of units produced. Find AR, AC, MR and MC?
Answer:
R = 600q – 0.03q2
C = 150q + 60000

(i) AR = \(\frac { R }{ q }\)
= \(\frac{600 q-0.03 q^{2}}{q}\)
= \(\frac { 600q }{ q }\) – \(\frac{0.03 \mathrm{q}^{2}}{\mathrm{q}}\)
= AR = 600 – 0.0.q

(ii) AC = \(\frac { c }{ q }\)
= \(\frac { 150q + 60000 }{ q }\)
= \(\frac { 150q }{ q }\) + \(\frac { 60000 }{ q }\)
AC = 150 + (\(\frac { 60000 }{ q }\))

(iii) MR = \(\frac { dr }{ dq }\)
R = 600q – 0.03q
\(\frac { dR }{ dq }\) = 600 (1) – 0.03 (2q)
MR = 600 – 0.06q

(iv) MC = \(\frac { dc }{ dq }\)
C = 150q + 60000
\(\frac { dc }{ dq }\) = 150 (1) + 0
MC = 150

Question 5.
If a firm faces the total cost function TC = 5 + x2 where x is output, what is TC when x is 10?
Answer:
TC = 5 + x2
TC = 5 + 102
TC = 5 + 100
∴TC = 105

Question 6.
If TC = 2.5q3 – 13q2 + 50q + 12 derive the MC function and AC function?
Answer:
\(\frac{dc}{dq}\) = MC
AC = \(\frac{TC}{q}\)
\(\frac{dc}{dq}\) = 2.5(3)q2 – [13 × 2]q + 50
MC = 7.5q2 – 26q + 50
AC = \(\frac { 2.5q^{ 3 }-13q^{ 2 }+50q+12 }{ q } \)
∴ AC = 2.5q2 – 13q + 50 + \(\frac{12}{q}\)

Answer the following questions in about a page:

Question 1.
A Research scholar researching the market for fresh cow milk assumes that Qt = f (Pt, Y, A, N, Pc) where Qt is the quantity of milk demanded, Pt is the price of fresh cow milk, Y is average household income, A is advertising expenditure on processed pocket milk, N is population and Pc is the price of processed pocket milk.
Answer:

  1. What does Qt = f (Pt, Y, A,N, Pc) mean in words?
  2. Identify the independent variables.
  3. Make up a specific form for this function.

(Use your knowledge of Economics to deduce whether the coefficients of the different independent variables should be positive or negative.)

1. Qt is the function of Pt, Y, A, N, Pc
Pt – Price of fresh cow milk
Y = Average household income
A = Advertising expenditure on processed pocket milk
N = Population
Pc = Price of processed pocket milk

2. Identify the Independent variables.
“Y” = Average household income
“N” = Population [“N” are Independent Variables]
Pc = Price of processed pocket milk
“Pc” = depending “Pt”
= Pc depending “A”
“A” = depending “N”
∴ Pc depending “Pt”, “A”, and “N”.

3. Make up specific form for this function [use your knowledge of Economics to deduce whether the co-efficient of the different independent variables should be positive or negative]

  • “Pc ” = Price of processed pocket milk
    When the price of processed milk increases and the quantity demanded of fresh milk decreases.
  • “N” = Population
    When the population increases and the quantity of milk demanded Increases.
  • “A” = Advertising expenditure on processed pocket milk
    When advertising expenditure on processed pocket milk increases the quantity of milk demanded. Increases.

“Y” – Average household Income
When average household income Increases and the quantity of milk demanded Increases.
“Pt” – Price of fresh cow milk
When the price of fresh cow milk Increases the quantity of milk demanded decreases.
∴ Qt = (-Pt) (+Y) (+A) (+N) (- Pc)
(-) means decreases; (+) means Increases
∴ Qt = [- Pt + Y + A +N – Pc]

Question 3.
The demand and supply functions are Pd = 1600 – x4 and Ps = 2x2 + 400 respectively. Find the consumer’s surplus and producer’s surplus at the equilibrium point?
Answer:
Pd = 1600 – x2
Ps = 2x2 + 400
Pd = Ps
1600 – xc = 2x2 + 400
⇒ 1600 – x2 – 2x2 – 400 = 0
⇒ -3x2 + 1200 = 0
x2 = \(\frac{1200}{3}\) = \(\frac{400}{1}\)
x = ±\(\sqrt{400}\)
x = 20

When x = 20
Pd = 1600 – x2
= 1600 – (20)2
= 1600 – 400 = 1200
Pd = 1200
Ps = 2x2 + 400
= 2(20)2 + 400 = 2(400) + 400
Ps = 1200

PART – C

Answer the following questions in about a paragraph.

Question 1.
Mention the causes for Rural Poverty?
Answer:
Causes for Rural Poverty:

  • Unequal distribution of Land: The distribution of land is highly skewed in rural areas. Therefore, the majority of rural people work as hired labour to support their families.
  • Lack of Non-farm employment: Non-farm employment opportunities do not match the increasing labour force. The excess supply of labour in rural areas reduces the wages and increases the incidence of poverty.
  • Lack of public sector Investment: The root cause of rural poverty in our country is the lack of public sector investment in human resource development.
  • Inflation: Steady increase in prices affects the purchasing power of the rural poor leading to rural poverty.
  • Low productivity: Low productivity of rural labour and farm activities is a cause as well as the effect of poverty.
  • Unequal Benefit of Growth: Major gains of economic development are enjoyed by the urban rich people leading to a concentration of wealth. Due to defective economic structure and policies, gains of growth are not reaching the poor and the contributions of poor people are not accounted for properly.
  • Low Rate of Economic Growth: The fate of the growth of India is always below the target and it has benefited the rich. The poor are always denied the benefits of the achieved growth and development of the country.
  • More Emphasis on Large Industries: Huge investment in large industries catering to the needs of middle and upper classes in urban areas are made in India. Such industries are capital-intensive and do not generate more employment opportunities. Therefore, the poor are not in a position to get employed and to come out of poverty in villages.
  • Social evils: Social evils prevalent in the society like custom, believes, etc. increase unproductive expenditure.

Samacheer Kalvi 11th Economics Guide Chapter 10 Rural Economy

Question 2.
Explain the causes for Rural Unemployment?
Answer:
Causes for Rural Unemployment:

  • Absence of skill development and employment generation: Lack of Government initiatives to give required training and then to generate employment opportunities.
  • Seasonal Nature of Agriculture: Agricultural operations are seasonal in nature and depend much on nature and rainfall. Therefore, the demand for labour becomes negligible during the offseason. So, non-farm employment opportunities must be created.
  • Lack of subsidiary occupation: Rural people are not able to start subsidiary occupations such as poultry, rope making, piggery, etc. Due to shortages of funds for investment and lack of proper marketing arrangements.
  • Mechanization of Agriculture: The landlords are the principal source of employment to the farm labour. Mechanization of agricultural operations like ploughing, irrigation, harvesting, threshing, etc. reduces employment opportunities for farm labour.
  • Capital-Intensive Technology: The expanding private industrial sector is largely found in urban areas and not creating additional employment opportunities due to the application of capital intensive technologies. The government must establish firms to absorb surplus labor-power.
  • Defective System of Education: The present system of education has also aggravated the rural unemployment problem. A large number of degree-producing institutions have come in recent years. Students also want to get degrees only, not any skill. Degrees should be awarded only on the basis of skills acquired. The unemployed youth should get sufficient facilities to update their skills.

Answer the following questions in about a page.

Question 1.
Explain the Monetary and Financial Sector Reforms?
Answer:
Monetary reforms aimed at doing away with interest rate distortions and rationalizing the structure of lending rates. The new policy tried in many ways to make the banking system more efficient.

Some of the measures undertaken were:
1. Reserve Requirements:

  • Reduction in Statutory liquidity ratio [SLR] and the cash reserve ratio [CRR] was recommended by the Narasimham Committee Report, 1991.
  • It was proposed to cut down the SLR from 38.5 percent to 25 percent within a time span of three years.

2. Interest Rate Liberalisation:
RBI controlled:

  • The interest rates are payable on deposits.
  • The interest rate could be charged for bank loans.
  • Greater competition among public sector, private sector, and foreign banks and elimination of administrative constraints.
  • Liberalization of bank branch licensing policy in order to rationalize the existing branch network.
  • Banks were given the freedom to relocate branches and open specialized branches.
  • Guidelines for opening new private sector banks.

Question 2.
Explain the Agrarian crisis after reforms?
Answer:
1. High input Costs:

  • The biggest input for farmers is seeds.
  • Before liberalization, farmers across the country had access to seeds from state government institutions.
  • The institutions produced their own seeds and were responsible for their quality and price.
  • India’s seed market was opened up to global agribusinesses.
  • The deregulation of many state government institutions were closed down in 2003.
  • Seed prices shot up and fake seeds made an appearance in a big way.

2. Cutback in agricultural subsidies:

  • Farmers were encouraged to shift from growing a mixture of traditional crops to export-oriented “cash crops” like chili, cotton, and tobacco.
  • Liberalization policies reduced the subsides on pesticide and fertilizer and elasticity.
  • As a result, prices have increased by 300%.

3. Reduction of import duties:

  • With a view to open India’s markets, the liberalization reforms also withdrew tariffs and duties on imports.
  • By 2001, India completely removed restrictions on imports of almost 1,500 items including food.

4. Paucity of credit facilities:

  • The lending pattern of commercial banks, including nationalized banks, drastically changed.
  • As a result, the loan was not easily adequate.
  • This has forced the farmers to rely on moneylenders who charge exorbitant rates of interest.

Question 30.
Elucidate the different types of land tenure systems in colonial India?
Answer:
Land Tenure refers to the system of land ownership and management. The features that distinguish a land tenure system from the others relate to the following:

  • Who owns the land
  • Who cultivates the land.
  • Who is responsible for paying the land revenue to the government.

Based on these questions, three different types of land tenure existed in India before Independence. They were:

  • Zamindari System or the Landlord-Tenant System.
  • Mahalwari System or Communal System of Farming.
  • Ryotwari System or the Owner-Cultivator System.

Zamindari System or the Landlord-Tenant System:

  • This system was created by the British East India Company when in 1793, Lord Cornwallis introduced the ‘Permanent Settlement Act’.
  • Under this system, the landlord or the Zamindars were declared as the owners of the land and they were responsible to pay the land revenue to the government.
  • The share of the government in total rent collected was fixed as 10/11th, the balance going to the Zamindars as remuneration.

Mahalwari System or Communal System of Farming:

  • After the introduction of this system, it was later extended to Madhya Pradesh and Punjab.
  • The ownership of the land was maintained by the collective body usually the villagers which served as a unit of management.
  • They distributed land among the peasants and collected revenue from them and pay it to the state.

Ryotwari System (or) the Owner-Cultivator System:

  • This system was initially introduced in Tamil Nadu and later extended to Maharashtra, Gujarat, Assam, Coorg, East Punjab, and Madhya Pradesh.
  • Under this system, the ownership rights of use and control of land were held by the tiller himself.
  • There was a direct relationship between owners and tillers. This system was the least oppressive system before Independence.

Question 35.
Discuss the Indian economy during the British Period?
Answer:
Britain had exploited India over a period of two centuries of its colonial rule. On the basis of the form of colonial exploitation, economic historians have divided the whole period into three phases namely the period of merchant capital, the period of industrial capital, and the period of finance capital.

1. Period of merchant capital (1757 to 1813):
The only aim of the East India company was to earn profit by establishing monopoly trade. India was considered as the best hunting ground for capital. By attaining political power the objective of monopoly trade was fulfilled. The company administration succeeded in generating huge surpluses which were repatriated to England.

2. Period of industrial capital (1813 to 1858):
India had become a market for British textiles. Indians were exploited by fixing low prices for exports and high price for imports. India’s traditional handicrafts were thrown out of gear.

3. Period of financial capital (Late 19th century – 1947) : Finance imperialism began to entrench. Britain decided to make massive investments in various fields by plundering Indian capital.

4. The land tenure system in India: Land tenure refers to the system of land ownership and management.
The Zamindari system, the Mahalwari system and the Ryotwari system were the systems of land tenure introduced by British.

5. Problems of British rule : Their profit motives led to drain of resources from India. The handicraft industries were collapsed.
The British rule stunted the growth of Indian enterprise. Capital formation in India was retarded.

Question 36.
Explain the role of SSIs in economic development?
Answer:
1. Provide Employment:

  • SSIs use labor-intensive techniques. Hence, they provide employment opportunities to a large number of people. Thus, they reduce the unemployment problem to a great extent.
  • SSIs provide employment to artisans, technically qualified persons and professionals, people engaged in traditional arts, people in villages and unorganized sectors.
  • The employment-capital ratio is high for the SSIs.

2. Bring Balanced Regional Development:

  • SSIs promote decentralized development of industries as most of the SSIs are set up in backward and rural areas.
  • They remove regional disparities by industrializing rural and backward areas and bring balanced regional development.
  • They help to reduce the problems of congestion, slums, sanitation and pollution in cities. They are mostly found in outside city limits.
  • They help in improving the standard of living of people residing in suburban and rural areas in India.
  • The entrepreneurial talent is tapped in different regions and the income is also distributed instead of being concentrated in the hands of a few individuals or business families.

3. Help in Mobilization of Local Resources:

  • SSIs help to mobilize and utilize local resources like small savings, entrepreneurial talent etc., of the entrepreneurs, which might otherwise remain idle and unutilized.
  • They pave way for promoting traditional family skills and handicrafts. There is a great demand for handicraft goods in developed countries.
  • They help to improve the growth of local entrepreneurs and self-employed professionals in small towns and villages in India

4. Pave for Optimisation of Capital:

  • SSIs require less capital per unit of output. They provide quick return on investment due to shorter gestation period. The payback period is quite short in SSIs.
  • SSIs function as a stabilizing force by providing high output-capital ratio as well as high employment – capital ratio.
  • They encourage the people living in rural areas and small towns to mobilize savings and channelize them into industrial activities.

5. Promote Exports:

  • SSIs do not require sophisticated machinery. Hence, import the machines from abroad is not necessary. On the other hand, there is a great demand for goods produced by SSIs.
  • Thus they reduce the pressure on the country’s balance of payments. However, in the recent past large scale industries are able to borrow large funds with a low-interest rates and spend large sums on advertisements. Hence SSSs are gradually vanishing.
  • SSIs earn valuable foreign exchange through exports from India.

6. Complement Large Scale Industries:

  • SSIs play a complementary role to large scale sector and support large scale industries.
  • SSIs provide parts, components, accessories to large scale industries and meet the requirements of large scale industries through setting up units near the large scale units.
  • SSIs serve as ancillaries to large scale units.

7. Meet Consumer Demands:

  • SSIs produce a wide range of products required by consumers in India.
  • Hence, they serve as an anti-inflationary force by providing goods of daily use.

8. Develop Entrepreneurship:

  • SSIs, help to develop a class of entrepreneurs in society. They help the job seekers to become job givers.
  • They promote self-employment and a spirit of self-reliance in society.
  • SSIs, help to increase the per capita income of India in various ways.
  • They facilitate the development of backward areas and weaker sections of the society.
  • SSIs are adept in distributing national income in a more efficient and equitable manner among the various participants of the society.
