2.2 Examples

Query 1: What is the economic weight of the ‘European Union’ in the global economy, during the last 30 years, preferably decade by decade?

Answer: Let us first look at the data as it is. It might need interpretation because the composition of its membership changed from decade to decade since 1990. But we will handle that after looking at the raw data.

Table # 1 Percent share of EU in the global Gross National Income (GNI) from decade to decade

The above example on EU, because of the shifting membership of the EU turned out to be an atypical exercise. But it also discovered for us another dimension of using the Barometer for teaching and research purpose. A quick search on the search engines provided the necessary assistance to tailor the query to the standard solutions resolved by the Barometer. The lesson we learnt was that the primary target users of the Barometer are teachers’ students and researchers, who should be alerted to the need for minor research through search engines before solving the query through the Barometer. Whether such occasions may be a few or more, we shall discover upon our trial teaching and research activities.

Query 2: We now make a query which is simple in terms of its execution but complex in terms of its display. Can we compare the relative share of the three tiers of the world economy in 2020?

Answer: The comparative data for the three-tiered economy of the world is given in following table based on 2020 data.

Table # 2 PERCENT SHARE IN GLOBAL

Query 3: Can we now see the shifts in global economic power across the three tiers of the world economy, because of the three decades since 1990.

Answer: The tri-decennial (30 years) shift can be seen by the change, positive or negative, in their share of five indicators (as an example) in our previous query. We will compute this by finding the sores at two points in time and then computing the difference as change.

Table # 3 Tier # 1 Economies

Table # 4 Tier # 2 Economies

Table # 5 Tier # 3 Economies
