NSQR of National Accounts and Balance of Payments ONS Response - Overview ONS very supportive of review recommendations and suggestions and grateful to Dame Kate Barker and Art Ridgeway ONS accepts most of the recommendations completely and partially accepts the remainder (where full acceptance requires further practical considerations, review or consultation) Response to the review means we will: develop annual volume balanced Supply and Use tables. This will include the introduction of annual double deflation of Gross Value Added, reintroduction of the Purchases survey and a possible change to the alignment of GDP(O) with annual expenditure. develop the IDBR review capital stock methodology including consultation with experts prioritise development of the extended flow of funds dataset draw on wider statistical and economic expertise to support and enhance our work Response work will be open to public consultation later in 2015 and will influence future work plans 4

Flow of Funds Developing financial data is considered essential for identifying the build-up of risks in the financial sector and to understand better the financial connections. An important part of this development is the ‘Flow of Funds’. New tables published in BB14 (Chapter 14). 5

Flow of Funds ONS is considering wider options for developing Flow of Funds datasets, in conjunction with the Bank of England Wider consultation and user engagement will be taken forward this year A business case is being prepared around options by May/June

Scope of BB 2015 On-going work to address Gross National Income (GNI) reservations Classification changes Other methodological improvements Take on of new data and moving forward base and reference year 7

BB15 Communications Similar process to Blue Book 2014 Series of articles on impact of changes Seminars and user groups External peer review 8

Saving and “visible” income Users have requested a measure of the saving ratio that corresponds more closely to the economic factors that are pertinent to households' decisions on what to spend and what to save. ONS considering whether to publish a supplementary indicator that users may find useful, including reviewing the approach taken by other countries Stakeholders will be consulted ahead of any publication 9

Owner occupiers’ housing costs in CPIH National Statistics status was suspended for CPIH in August 2014 ONS and VOA have completed work looking into Owner Occupiers’ Housing (OOH) component Growth in private rents now more responsive to recession Still at odds with HPI, but rents a stock measure and HPI a flow measure 70% of rent updates result in no price change 12

OOH - next steps Improvements to OOH in CPIH will be introduced as part of the 2015 annual update on 24 March 2015 Revise only OOH component of CPIH back to 2005 Article documenting the improvements to be published 30 January 2015, responds to Johnson Review: Recommendation 21 Planned user event in February/March around housing statistics 13

OOH - next steps Also take opportunity of revision to VOA data to align OOH weight in CPIH with national accounts estimates historically and anticipate methodological changes to the measurement of imputed rents, planned for BB16. Begin process for re-accreditation of National Statistic status for CPIH (from 30 January 2015), aim for process to be completed March/April

Prices by webscraping ONS is looking at alternative options for obtaining price quotes including: 1. Scanner data 2. Web scraping Web scraping can be: 1. collected by the ONS directly 2. purchased. ONS is investigating both of these options – in two research phases Phase one: Web scraping started in April 2014 collecting 35 CPI/RPI items from 3 online supermarkets – 6,500 price quotes collected daily Prototype cleaning and classifying programs have also been set up – and exploratory analysis is being conducted on the data Phase two: Will assess data ONS has recently purchased from mysupermarket.com, and further explore methodological and technical challenges of using such data.....

Prices by webscraping Such data has the benefits of: 1. Being high frequency 2. Collecting many items 3. Timely collection It has its challenges, such as: 1.Item classification 2. Methodological challenges 3. Website diversity 4. Website change 5. Cleaning challenges ONS is learning/using open source tools, data science concepts and big data technologies to overcome these challenges High frequency data allow detailed investigation of price distributions at the lowest level The production of (very) experimental indices...more methodological research needed 16

Scanner Data Project Scanner data are point of sale data held within retailers’ systems. They can: o provide real-time price and quantity information, allowing for use of up to date weights o allow for complete coverage of sales by selected retailers o create data handling and acquisition challenges ONS has test scanner data from one UK retailer for two products (shampoo and toothpaste) Investigations are in early stages o Continue to explore potential uses o Learn from other countries whose – research is further advanced 17
