Which of the following is not a dimension of Global economy?

The correct answer is option 4: Barter economy

The global economy is characterized by features such as:

• Liberalization – Removal of trade barriers to encourage free flow of goods and services.

• Transnational corporations (TNCs) – Companies that operate across multiple countries.

• Globalisation of finance – Free movement of capital and integration of financial markets worldwide.

In contrast, the barter economy is a pre-modern system of exchange where goods are traded without money. It is not a feature or dimension of the modern global economy, which is based on monetary transactions and market systems.
