Study Notes

Introduction

Economics studies how societies transform resources into goods and services.
Aristotle and Adam Smith made initial contributions in the field.

Basic Assumptions of Economics

Scarcity is inescapable. Resources are limited while human wants are limitless.
Trade-offs are inherent in every choice.
People are rational; they compare benefits and costs.

Positive and Normative Economics

Positive economics describes and explains economic phenomena, making predictions.
Normative economics guides decisions—incorporating value judgements.

Efficiency as a Goal

Pareto efficiency means improving one person's well-being without harming another.

Microeconomics

Markets are collections of buyers and sellers of a good or service.
Demand curves illustrate how quantity demanded relates to price. Changes in prices and other factors shift demand curves.
Supply curves illustrate how quantity supplied relates to price. Changes in prices and other factors shift supply curves.
Equilibrium is where supply and demand intersect, no incentive to change behaviour.

Perfectly Competitive Markets

In perfect competition, numerous buyers and sellers mean no individual can impact market price.
Goods are standardized.
Buyers and sellers are fully informed about market price.

Economic Profits and Accounting Profits

Economic profit is total revenue minus all costs, including opportunity costs.
Accounting profit is total revenue minus explicit costs only.

Imperfect Competition

Monopolies occur when there are barriers to entry. These could be exclusive resource ownership, government grants, or natural advantages to scale.
Oligopoly arises when a few firms dominate a market. These firms might compete or cooperate, which significantly impacts market behavior.
Monopolistic competition exists where free entry exists, but firms produce slightly differentiated products.

Measuring Total Output: GDP

Gross Domestic Product (GDP) is the total market value of all final goods and services produced in a country.
GDP excludes intermediate goods (those used in the production of a final good).

Measuring Inflation: CPI

The Consumer Price Index (CPI) measures the change in the cost of a weighted average bundle of goods.

Money and Prices in the Long Run

Money is a medium of exchange, unit of accounting, and store of value.
The neutrality of money means that changes in the money supply affect only nominal (not real) quantities.

Short-Run Economic Fluctuations

Economic fluctuations, such as recessions and expansions, are a significant part of a developed economy.
The aggregate supply curve and aggregate demand curve interact to determine short-term output and price levels.
Fiscal and monetary policy can be used to mitigate the impact of fluctuations.

Climate Change-Economics Meets Ecology

Climate change poses significant global economic and ecological challenges.
Externalities, like pollution, are examples of where market mechanisms do not fully reflect the social costs and benefits of an action.
International agreements or institutional frameworks may be needed to address climate change.
