UN encourages countries to conduct ETS (if not doing so already) in respect the role of the surveys data in the economic research; UN has identified a handbook as a tool to assist member States in compiling and reporting internationally comparable tendency survey data; the shortcoming of a unique guide for “economic” tendency surveys (the current handbooks deal with the consumer surveys or the business “traditional” surveys, excluding e.g. agriculture sector) comprising: • best practices • harmonized principles • Guidance; 3 Handbook on Economic Tendency Surveys - UN Workshop on short-term economic indicators, Hangzhou, 8 October 2014 The process Preparation step: the team International working group The Italian National Statistical Institute (ISTAT) – leader – Italy Statistics Netherlands (CBS) – Netherlands The Swiss Economic Institute (KOF – ETH) – Switzerland Philippine Statistical Authority (PSA former NSCB) – Philippines The Organisation for Economic Co-operation and Development (OECD) 4 Handbook on Economic Tendency Surveys - UN Workshop on short-term economic indicators, Hangzhou, 8 October 2014 The process Preparation step: the Team External revisers The European Commission (DG Ecfin) French National Institute of Statistics and Economic Studies (INSEE) Contributors Instituto Brasileiro de Economia, Fundação Getulio Vargas, IBREFGV 5 Handbook on Economic Tendency Surveys - UN Workshop on short-term economic indicators, Hangzhou, 8 October 2014 The process Milestones February 2012: decision of the Statistical Commission of UN to produce a handbook; October 2012: constitution of the Working Group; Time span for the realization of a first draft of the handbook: January 2013 - October 2013; November 2013: the first draft was submitted to the revisers; Realization of a second draft (including further comments of the revisers): January-may 2014; UN Global consultation: 28 July – 29 August 2014; The finalization of the handbook is expected by beginning of 2015. 6 Handbook on Economic Tendency Surveys - UN Workshop on short-term economic indicators, Hangzhou, 8 October 2014 The process Method of work • No meetings (pros and cons); • No multi-conference call (time gap between countries and language difficulties); • Bilateral conference call; • Contacts only by e-mail; • Standardization of the template to write the chapters; • always in touch with UNSD; • Hard centralized work of harmonization and revision (different experiences, languages…) to avoid repetitions, non homogeneous 7 Handbook on Economic Tendency Surveys - UN Workshop on short-term economic indicators, Hangzhou, 8 October 2014 The Process Arranging the drafting The drafting of the handbook was arranged for chapters: each chapter deals with a (main) topic.
