Question 4
Complete
Mark 2.00 out of 2.00
Pick n Pay, Spar, Checkers and Shoprite came together to fix the price of gas heaters in July
2022. This was so that they could keep the price at a level to ensure that all four stores
remained profitable. On which area of study in economics does this focus?
a. microeconomics
b. development economics
c. macroeconomics
d. international economics
The four retail stores (Pick n Pay, Spar, Checkers and Shoprite) coming together to agree on a
price level for gas heaters is called a cartel. The purpose of a cartel is to increase the
profitability of firms and to prevent competitors from entering the market for certain goods.
This scenario applies to microeconomics because it deals with the interaction of firms in a
market and the effects of their actions on prices.
Macroeconomics focuses on the performance of the economy as a whole by providing an
overall view of the economic system of a country. This area of economics focuses on total
production, income, spending, economic growth, employment and unemployment, inflation,
price levels and the balance of payments.
International economics focuses on the financial flows, exchange rates and differences in
productive resources between countries. It is also concerned with the role of institutions
affecting transactions between countries. For example, international economics looks at how
a multinational company (for example Vodafone) investing in South Africa affects
employment, technology and skills transfer.
Development economics focuses on improving the economic, social and fiscal conditions in
developing countries. It also highlights the differences between developed and developing
countries, and how these differences can be mitigated.
