  2. 2. USERS PRODUCERS WORKSHOP PRESENTATION ON PRICE STATISTICS BY ABDUL AZEEM SAHITO DIRECTORPRICE STATISTICS SECTION FBS, KARACHI
  3. 3. PRICE STATISTICS• PRICE STATISTICS INCLUDES COLLECTION OF RETAIL AND WHOLE SALE PRICES AND COMPUTATION OF FOLLOWING INDICES:-• 1. CONSUMER PRICE INDEX (C.P.I)• 2. WHOLESALE PRICE INDEX (W.P.I)• 3. SENSITIVE PRICE INDICATOR (S.P.I)
  4. 4. Consumer Price Index• “ Consumer Price Index is the main measure of price changes at the retail level. It measures changes in the cost of buying a representative fixed basket of goods and services and is generally accepted as a measure of inflation in the country”.
  5. 5. SENSITIVE PRICE INDICATOR (SPI)• Sensitive Price Indicator (SPI) is designed to assess price movement of essential consumer items at short intervals (on weekly basis ).
  6. 6. WHOLE SALE PRICE INDEX (WPI)Wholesale price index ( WPI) is designed tomeasure the change of price in the primaryand wholesale markets. 
  7. 7. Why Three Types of Indices?• CPI measures Inflation rate in the country• SPI is computed to assess the price movement of essential commodities at short interval of time to review the price situation in the country.• WPI measures the General Price level in the whole sale market.
  8. 8. WHAT CPI MEASURES?• It measures Price changes of fixed market basket of goods and services of constant quality and quantity.• It tells how much cost of living has risen or fallen due to price changes irrespective of changes in consumer behaviour or quality of goods.• It does not reflect the cost of living or in house hold consumption expenditure as such but only the influence of price fluctuation on the trend.
  9. 9. Selection of Markets/Outlets and Cities• Items are selected on the basis of Family Budget Survey• Markets are selected through retail and wholesale trade survey.• Outlets are selected on transaction value basis.• Cities are selected on population basis• Stratified sampling are used for selection of cities.
  10. 10. Weights for CPI The results of Family Budget Survey provide the average percentage expenditure(Consumption pattern) of Households on each item/each commodity group and for each income group for the cities covered in CPI. These average percentage expenditures on item and commodity groups are called weights and are being used in computation of the CPI. Po x qo Wi = ------------- x 100 ∑ Po x qoExample: 1. Total Expenditure: Rs. 3000, 2. Expenditure on Wheat Flour:- Rs. 100 3. % of Expenditure on Wheat flour = (100/3000)*100 = 3.33 Weight of Wheat flour = 3.33%

  16. 16. FORMULA USED FOR COMPUTATION OF CPILaspeyres formula as given below is being used for the computation of CPI. ∑ (Pn/Po) x wi In = --------------------- x 100 ∑ wiWhere In = CPI for the nth period Pn = price of an item in the in the nth period Po = price of an item in the base period wi = weight of the ith item in the base period = Po x qo / ∑ Po x Qo ∑ wi = Total weight of all items.

  21. 21. WEIGHTS FOR WPI• The value of marketable surplus is being used for deriving weights of commodities/items included in WPI. The value of marketable surplus is the value of commodity available for sale in wholesale market. It is equal to the total value of production less consumption by the producers less exports (if any) plus imports.• Example:- Production – Self Consumption +Imports- Exports Wheat = (100 )-(20) + (10) – (10) =80 Value of Marketing Surplus= 80 x 1000 = 80000 Total Value of all the Items included in WPI =100,0000 % of Wheat in Total Value = (80000/1000000) x 100 = 8%
