Introduction

Estimating household expenditure on

dwelling services in the GDP

Calculating PPPs for dwelling services

HOUSING

Rentals Owner-occupied

Actual expenditure by households on rents for

dwellings

Estimate of how much owner-occupiers would have paid in

rent if not owning their dwellings

Choosing Methods to Apply

Are more than 25% of dwellings rented?

Are most rented dwellings either

occupied by its citizens and not subsidized?

Are rented dwellings distributed evenly

throughout the country?

<THE USER COST METHOD>Obtain expenditure weights by:

- estimating actual rents paid for rented dwellings- applying the user cost method for owner-occupied dwellings.

<THE STANDARD APPROACH>Obtain expenditure weights by:

- estimating actual rents paid for rented dwellings;- imputing rents for owner-occupied dwellings using rents actually paid for similar dwellings.

Intra-country Validation 1

Rents Data

Rents and metadata to be added to the validation tool (excel)

Rents and metadata to be checked for errors and discrepancies

Rents to be checked for sub-national plausibility based on NCA’s market knowledge

Sub-national comparison between rents with similar specificationse.g. rents in the capital city < rents in rural area Populous regions generally have higher rents given similar specs

Rents to be checked for temporal plausibility based on NCA’s market knowledge

Between collection periods (seasonal variability)Between the 2005 and 2011 rounds

Totals should be equal

Number of occupants divided by number of

dwelling units needs to be plausible

Number of units with inside water is generally higher

than number of units with private toilet

Inter-country validation

Rents Data Quantity Data

Convert rents in LCU to rents in common currency

Similar validation as basic editing from the intra-country process

Analytical Tables (QT, DT)

Temporal Analysis for Annual Data

Step 1

Step 2

Step 3

Together with Expenditure data, calculate Volume measure

and check plausibility

Step 4

Compare both resultsStep 5

Evaluation of completeness of Quality Indicators

Calculate quality-adjusted volume

Together with Expenditure data, calculate Indirect PPPsand check plausibility
