Questions about Microeconomics
Short answers, pulled from the story.
Who coined the term microeconomics and when was it first used?
Pieter de Wolff coined the phrase microeconomics in a 1941 article. He expanded Ragnar Frisch's concept from 1933 which established the separation between micro-dynamic and macro-dynamic analysis.
What are the core assumptions of consumer theory in microeconomics?
Consumer theory assumes individuals possess stable preferences that are both complete and transitive. A technical requirement demands preference relations be continuous to ensure utility functions exist and allow for differentiable results.
How do firms distinguish between fixed costs and variable costs in production models?
Fixed costs include rent, salaries, and utility bills that do not change with output levels while variable costs encompass raw materials and delivery expenses that fluctuate with quantity produced. Over periods spanning two to three years previously fixed costs can become variable as firms adjust machinery and labor.
Which market structures fall under imperfect competition according to microeconomic definitions?
Imperfect competition exists between perfectly competitive and monopoly extremes featuring firms like Pepsi, Coke, Sony, Nintendo, and Microsoft. This category includes oligopolies dominated by small numbers of firms and monopolistic competition where many firms sell slightly differentiated products.
