Lecture-2: Basic Concepts of Economics Part-I (Macroeconomics) by S.Maitra, Associate Professor, Civil Services Study Centre, Administrative Training Institute, Kolkata (Feb 2014)

Gross domestic product (GDP): The sum of values of all final goods and services produced within the geographical limit of a country.
Gross National Product (GNP): The sum of values of all final goods and services produced by the citizens of a country within the country and the rest of the world. Gross National Product (GNP) =  Gross Domestic Product (GDP) + Net Factor Income from Abroad (NFIA)    
Gross domestic product at market price (GDPMP): While deriving GDP of a country we estimate value added at the market prices. The estimate of GDP obtained this way is known as GDP at market price.
Gross National Product at Factor Cost (GNPFC): Market prices normally include indirect taxes net of subsidies. Gross national product at factor cost {GNPFC) is simply, Gross national product at market price (GNPMP) minus net  indirect taxes (Net IT), i.e.       GNPFC  = GNPMP – Net IT
Net National Product (NNP):  Net National Product (NNP) is simply obtained as gross national product (GNP) minus depreciation (D) i.e. Net National Product (NNP) = Gross National Product (NDP) -- Total Depreciation (D). Fixed capitals have their own life-time and depreciates in value every period of time after their participation in the productive process. Depreciation of fixed capital takes place because of their normal ‘wear and tear’.
National income (NI): Net national product at factor cost is equivalent to the notion of national income {NI), which the accrual of income to all normal residents in a country due to their participation in production anywhere in the world. Therefore,                   National Income(NI) = NNPFC
GDP Deflator: The GDP deflator, also called the implicit price deflator for GDP, is defined as the ratio of nominal GDP to real GDP:
                            GDP Deflator = (Nominal GDP/ Real GDP)
Nominal GDP measures the value of the output of the economy at current prices. Real GDP measures output valued at constant prices. The GDP deflator measures the price of output relative to its price in the base year.
Aggregate demand shock: Shocks such as change in government expenditure or change in money supply that cause a change in aggregate demand in an economy.
Aggregate supply shock: Shocks such as increase in petroleum price, a drought etc. that lead to a change in aggregate supply in an economy.
Depreciation: The reduction in value of asset through wear and tear. Also, fall in the value of a currency in terms of another currency.
Rational expectations: Expectations about the future making best use of available information.
Efficiency wage: Modern-sector urban employers sometimes pay a higher wage than the equilibrium wage rate in order to attract a higher-quality work-force or to obtain higher productivity on the job.

Keynesian model: Model developed by Lord John Maynard Keynes in the early 1930s to explain the cause of economic depression and hence the unemployment of that period. The model states that unemployment is caused by insufficient aggregate demand and can be eliminated by increasing government expenditure. Increase in aggregate demand would lead to increase in production and hence create further employment.
Laissez-faire: Free-enterprise market economy without any government intervention.
Macroeconomic instability: When an economy is passing through a phase with high inflation accompanied by rising budget and trade deficits and a rapidly expanding money supply.
Macroeconomlc stablllzatlon: Policies designed to eliminate macroeconomic instability.
Procyclical fiscal policy: Changes in government spending and taxes that increase the cyclical fluctuations in the economy instead of reducing them.
Natural rate of unemployment The average rate of unemployment around which the economy fluctuates. The natural rate is the rate of unemployment toward which the economy gravitates in the long run, given all the labor-market imperfections that impede workers from instantly finding jobs.
Recession: A recession is a decline in a country's gross domestic product growth for two or more consecutive quarters of a year.
Accounting classification of government expenditure:
(i)           Revenue and Capital (ii) Developmental and Non-Developmental and (iii) Plan and Non-Plan.
Revenue and capital expenditure:
  Expenditures that result in the creation of new assets and those which do not.
  Revenue expenditure is for the normal running of government departments and various services, interest charges etc.
  The main purpose of the capital account is to show the gross and net capital formation in the public sector during the accounting period. Capital expenditure results in creation of assets in the economy.
Revenue and capital budget:
  Government budget comprises Revenue Budget and Capital Budget.
  Revenue budget consists of revenue receipts of government (tax revenues and other revenues) and the expenditure met from these revenues.
  Tax revenues comprise proceeds of taxes and other duties levied by the Union.
  Revenue expenditure is for the normal running of government departments and various services. Broadly speaking, expenditure which does not result in creation of assets is treated as 'Revenue expenditure'. All financial administration grants given to state governments and other parties are also treated as revenue expenditure.
  Capital budget consists of capital receipts and payments.
  The main items of capital receipts are: a) loans raised by government from public which are called market loans, b) borrowings from Reserve Bank of India and other parties through sale of Treasury Bills, c) loans received from foreign governments and d) loans granted by Central government to state and union territory governments and other parties.
Capital expenditure:
  A capital expenditure may be defined as any expenditure the benefits of which extend over a period of time exceeding one year.
  Capital expenditure is the expenditure which is intended for creating concrete assets of a material character in the economy.
  Examples of capital expenditure are the acquisition of assets like land, buildings machinery, equipment and also investment in shares and loans and advances granted by Central government to state and union territory governments, government companies etc.
Developmental and non-developmental expenditure:
  Developmental expenditure comprises expenditure incurred on education. medical care, public health and family planning, labour and employment, agriculture, cooperation, irrigation, transport and communication and other miscellaneous services. Expenditure incurred on these items both on Revenue and Capital accounts is also treated as development expenditure.
  Non-Developmental expenditure, on the other hand, comprises expenditure incurred on items like defence, collection of taxes and duties, administrative services, interest on debt and other services, stationery and printing and other expenditure on general services.
  Developmental expenditure leads to economic growth and development whereas Non-Developmental expenditure does not, at least directly.
Plan and Non-Plan Expenditure:
  Plan expenditure refers to the expenditure incurred by the Central Government on programmes / projects, which are recommended by the Planning Commission.
  Non-Plan expenditure, on the contrary, is a generic term used to cover all expenditure of government, not included in the plan.
  The distinction between 'plan expenditure' and non-plan expenditure' is purely an administrative classification.
  Non-Plan expenditure consists of many items of expenditure, which are obligatory in nature.
  Items of expenditure, such as interest payments, pensionary charges, statutory transfer to states come under the obligatory nature.
  Defence, internal security are essential obligations of a state.
  Besides, there are special responsibilities of the Central Government like external affairs, currency and mint, cooperation with other countries and the expenditure incurred in this connection are treated as "non-plan" expenditure.
  Of all the major items of Non-plan expenditure of the Central Government, interest payments, defence, subsidies take the lion's share of expenditure.
Revenue Deficit, Fiscal Deficit and Primary Deficit of Central Government:
  Revenue Deficit = Revenue expenditure – Revenue receipts
  Fiscal Deficit = Total expenditure—Revenue receipt— Recovery of  loans                            — Other receipt                            
  Primary  Deficit = Fiscal Deficit – Interest payment
