A PRESENTATION ON THE STATUS OF ECONOMIC STATISTICS (MANUFACTURING) IN UGANDA By John Bonaventure Musoke Senior Statistician www.ubos.org
“A CANDLE LOOSES NOTHING BY LIGHTING ANOTHER CANDLE” Prof. Ssenteza Kajubi www.ubos.org
Content • The Business Register 2001/2002 and 2006/7 • Uganda Business Inquiry 2000/2001 • Index of Industrial Production (IoP – M) • Producer Price Index (PPI) • Challenges www.ubos.org
The Business Register 2001/2002 Defn: A business register is a record of all active business establishments. Essentially it contains structural information about each business. • Objectives - Create a comprehensive list of businesses • Provide a frame for future business surveys www.ubos.org
The Business Register ….. • Prior to the start of the Registration exercise an attempt was made to compile the register from administrative sources; • The Uganda Revenue Authority • Uganda manufacturers Association (UMA) • Uganda Investment Authority etc. www.ubos.org
The Business Register ….. • Variables collected • Name of Establishment, Activity ( ISIC), Location, GPS Coordinates, Tel:, Postal Address, Employment by sex, Type of Ownership, Start date, if enterprise – name. www.ubos.org
The Business Register ….. • Coverage We covered all businesses operating from a fixed location, regardless of employment size band A total of 160,883 businesses were registered out of which 11,968 were for manufacturing www.ubos.org
THE UGANDA BUSINESS INQUIRY (UBI) 2000/2001 Defn: This is an economic survey covering all sectors in the economy for the financial year 2000/2001 www.ubos.org
UBI Cont……… • Objectives • Compute VA for estimating GDP • Estimate capital Formation • Update input output table • Compile SAM • Update weights for IIP • Establish wts for PPI www.ubos.org
GO and VA for manufacturing 2000/1 www.ubos.org
Annual Business Inquiry 2006/7 • In order to produce high frequency data that can enable us update these important indicators we are now carrying out an ABI with ref. yr 2006/7. We finished data collection and have just finished data entry. A draft report is expected around July 2009. www.ubos.org
Index of Production (Manufacturing) By John B. Musoke www.ubos.org
Historical Background of IIP • Work started in 1990 after the Census of Business Establishments (COBE) • The IIP was based mostly on measuring quantities of production for products available in the base period. www.ubos.org
Errors within the IIP System • Challenges encountered in using Quantity to measure volume change…. • Establishments that close • New Establishments and products • Non Homogeneous products • Conversion factor related problems or problems related to human error www.ubos.org
Index of Production (IoP) • Index rebranded IoP to expand and Cover • Manufacturing • Services • Utilities • Mining www.ubos.org
IoP – Manufacturing……. • The index computation mostly utilizes deflated Sales values to measure change. It still remains a volume/quantity index. Q * P = V Q = V/P Qindex = Vindex/Pindex www.ubos.org
IoP – Manufacturing……. • Just as PPI, data for IoP is collected from formal manufacturing across the country majority of it coming from the industrial belt of Uganda C:\Documents and Settings\john.musoke.UBOS.000\My Documents\Maps\ugandan map1.doc www.ubos.org
IoP – Manufacturing……. • Monthly data is collected on a quarterly basis but entered by month in an Excel data file.(IoP DATA SALES) There are three sources of data:- • Survey data • VAT data • Quantities data from mandated Authorities www.ubos.org
IoP – Manufacturing……. • The index is derived in two steps: • First, for each “basic heading” (product or activity group) a value index is compiled by adding total turnover for each business (no weighting – full coverage assumed) • The value index is then divided by a corresponding price index (PPI) • This operation delivers volume indices at “basic heading” level www.ubos.org
IoP – Manufacturing……. • Second, these basic level indices are combined using the Laspeyres formula into the major Divisions/Groups and all Manufacturing. • The weights used to aggregate are based on gross value added taken from the UBI www.ubos.org
IoP – Manufacturing……. • The index is based on 2002 • Until June 2004, the basic heading indices were based on the old system (quantities) • From July 2004 onwards, deflated turnover has been adopted in most cases • The new indices are “linked” to the old before being aggregated. www.ubos.org
IoP – Manufacturing……. Quality control (Sales are much more variable than prices and more subject to error) • We calculate the response rates based on known (or assumed) average values of turnover in the previous 12 months and impute for non-respondents. • We check the month-to-month change in sales values and query large changes www.ubos.org
IoP – Manufacturing……. • Challenges • Correcting outliers with VAT data. • Reliability of monthly series • Using survey data – small economy • Using survey data – few estabs. www.ubos.org
UGANDAS EXPERIENCE WITH THE PRODUCER PRICE INDEX (LUSAKA 4th – 7th May 2009) www.ubos.org
What is a Producer Price Index (PPI)? • PPI is a PRICE index (number) used to measure the rate of change in the prices of goods and services bought and sold by producers. • PPIs can differently be calculated to suit specific goals thus we have a PPI for Manufacturing • PPIs for Mining and Quarrying, Agriculture, Hotels and Utilities are in the initial stages of development. www.ubos.org
Output PPI.. • UBOS started compiling PPIs (Manufacturing) in 2004.What is generated is an output PPI which measures the rate of change in the prices of products sold as they leave the producer. • The PPI generated is categorized btn. - the Local Market (PPI for Local Market) - for goods and services produced for export, (PPI for Exports) • And PPI combined which combines the two above www.ubos.org
Which PPI are we measuring? • PPI-M measures both goods produced for the local market and those produced for export. • This PPI covers the ‘formal’ Manufacturing sector • It measures the change in the effective unit selling prices received by manufacturers for products sold for both the home market and for exports. www.ubos.org
PPI - M cont… • Products are priced at Basic Price • Basic Price is the price per unit of goods/ services receivable by the producer. Because the producer does not receive taxes on products but does receive subsidies. Taxes on products (excise, non-refundable VAT, taxes on exports, etc) are excluded, while subsidies on products are included. www.ubos.org
Methodology & Sample Size determination WHY PPI was generated? • Out of the UBI which was conducted in 2000/01, the Bureau then had comprehensive data on Value Added (VA) and Gross Output (GO) for establishments. The data on GO was then used for generating weights for PPI-M. www.ubos.org
Methodology Ctd • The PPI Manufacturing is based on a sample of establishments with 10 or more employees as reported during the UBI. • A wide range of representative products were selected in July 2004 • PPI-M covers all ISIC Manufacturing Divisions from 15 to 37 (Table of ISIC) www.ubos.org
Methodology Ctd • A sample of 200 establishments as of now are covered in the PPI with close to 600 products. • The sampling method used was Probability Proportional to size combined with Concentration of businesses and personal judgment based on previous data/information. • There are 36 main headings based on 4-digit ISIC. www.ubos.org
Challenges before • Establishments that close • Inclusion of new establishments and products • Non Homogeneous products • Conversion factor related problems or problems related to human error www.ubos.org
Methodology Contd… • These are collapsed into 21 groups. Closely related activity codes producing almost homogenous commodities are grouped together to form the 21 as shown in the table. • Which are later put into 8 major headings which are re-grouped to suit the requirements in National Accounts. www.ubos.org
Challenges after • Correcting outliers within VAT data files. • Variability of monthly sales/ turnover series • Using survey data – respondent fatigue • Using survey data – few establishments • Need for specialized respondents • Harmonizing data collection within UBOS and without www.ubos.org
Challenges cont… • Getting transaction prices (actual) other than price-list prices. www.ubos.org
