Introduction to Microeconomics

Flashcards covering key themes, theories, market concepts, and price analysis from the 'Introduction to Microeconomics' lecture.

What core economic problem does microeconomics primarily deal with?

Scarcity, encompassing limited budgets, time, and ability to produce.

What fundamental concept is central to decisions made by workers, firms, and consumers in microeconomics?

Tradeoffs.

What does 'Consumer Theory' describe?

How consumers maximize their well-being by using their preferences to make decisions about tradeoffs, such as consumption versus savings or one good versus another.

What types of tradeoffs do workers face according to microeconomics?

Tradeoffs between working now and obtaining more education/training, and tradeoffs between labor and leisure.

What is the 'Theory of the Firm'?

It describes how firms make decisions about what types of products to produce, given constraints on production capacity and financial resources.

How do prices influence economic decisions by workers and firms?

Workers make decisions based on wages (the price for labor), while firms base decisions on wages, prices for other inputs, and the prices for the goods they produce.

How are prices determined in market economies?

By the interaction of market participants, which are collections of buyers and sellers.

What is the primary purpose of economic theories?

To explain observed phenomena in terms of a set of basic rules and assumptions.

What is the relationship between economic theories and economic models?

Economic models are mathematical representations created from theories, used to make quantitative predictions.

How is the validity of an economic theory assessed?

By the quality of its predictions, given its underlying assumptions.

What is 'positive analysis' in economics?

Statements that describe cause-and-effect relationships, explaining phenomena and predicting future outcomes based on what is or will likely be.

How does 'normative analysis' differ from 'positive analysis'?

Normative analysis examines questions of 'what ought to be' and often involves value judgments, while positive analysis describes 'what is' or 'what will likely be'.

Define a 'market' in economic terms.

A collection of buyers and sellers that, through their actual or potential interactions, determine the prices of products.

What characterizes a perfectly competitive market?

A large number of buyers and sellers where no individual participant can influence the market price.

What defines a noncompetitive market?

Markets where individual producers can influence the price, often including groups like cartels.

What is a 'market price'?

The price prevailing in a competitive market for a good or service.

What does 'market definition' refer to?

Identifying which buyers and sellers should be included when considering a given market, based on its geographical boundaries and the range of products.

Why is market definition important for businesses and public policy?

For businesses, it helps identify competitors and set prices; for public policy, it informs decisions about mergers and their potential impact on consumer prices.

What is the difference between a nominal price and a real price?

A nominal price is the current dollar price of a good or service when sold, while a real price is adjusted for inflation using a deflator, reflecting its purchasing power.

What is the Consumer Price Index (CPI) used for in economics?

It is used as a measure of aggregate prices, recording the prices of a large market basket of goods purchased by a typical consumer over time, with percent changes indicating the rate of inflation.

How is the real price of a good calculated from its nominal price and CPI values?

Real Price (base year) = Nominal Price (current year) multiplied by (CPI in the base year divided by CPI in the current year).

What does the historical comparison of nominal and real minimum wage trends reveal?

While the nominal minimum wage has increased over time, the real minimum wage (adjusted for inflation) has shown little to no increase in purchasing power for decades, meaning a stable standard of living for those relying on it.

Why is it important to study microeconomics?

Microeconomic concepts are used by everyone to assist them in making choices as consumers and producers, and they are essential for analyzing complex decisions such as product development, pricing strategies, and government regulation.
