• This refers to those sectors of the economy which produce stuff that weigh lighter than other sectors that manufacture traditional goods and services.
• The term is used to emphasise the changing nature of economies as they increasingly concentrate on producing stuff that is intangible but also of much more valuable to consumers.
• Economic growth in the previous centuries depended largely on increasing the total quantity of physical inputs that went into production.
• Now, producing things of higher value requires the use of intellectual capital more than physical capital, which explains the rapid increase in the size of the weightless economy.
