Motivation
Introductory notes
 UN Statistical Commission considered an international programme of
work on short-term economic statistics as part of a coordinated
statistical response to the economic and financial crisis ;
 ETS are a theme comprised in the international programme because:
o ETS data have been recognized as tools to improve the
estimation of other economic indicators and as components of
composite indicators;
o Confidence indicators are useful in providing an early warning of
changes in economic activity (UN, EUROSTAT);

Motivation
Why an ETS handbook?
 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;

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

The Process
Arranging the drafting
The drafting of the handbook was arranged for chapters: each chapter
deals with a (main) topic.
 For each chapter:
 three/four working group members worked
 One role was assigned to each member, among:
• Leader (responsible of the chapter: it coordinated the drafting
of the chapter and, in some cases, it has contributed in the
drafting)
• Contributor
• Reviser
 For some chapters (it depends on the topic), an external reviser
(EC, INSEE) was assigned.
