Study Notes
Introduction to Economics
- Economics is the social science that studies how individuals satisfy their unlimited needs and desires with scarce resources.
- This involves trade-offs; obtaining more of one good often means sacrificing something else.
- Two perspectives exist:
-
Microeconomics: Focuses on decision-making processes at the individual level, including how individuals interact in markets, and considers factors like costs, benefits, and public interventions.
-
Macroeconomics: Focuses on the aggregate economy, including factors like GDP, price levels, income distribution and its evolution over time, growth, etc.
-
Analyzing Economics
-
Economics uses scientific methods:
- Observing reality
- Understanding it
- Testing theories and refining them
-
Theory (economic models) and data (econometrics) are used to understand problems, predict outcomes, and guide policy decisions.
The Cost-Benefit Principle
- An action should be taken if and only if the extra benefits from taking the action are at least as great as the extra costs.
- Additional benefits (MB) versus additional costs (MC) are important to consider.
The Principle of Not All Costs and Benefits
- Not all costs and benefits are equally important when making decisions. Opportunity costs, marginal costs, and marginal benefits matter.
- Sunk costs, average costs, and average benefits are not relevant in decision-making processes.
Failure to Understand the Average-Marginal Distinction
- The decision-making process should focus on marginal benefits and marginal costs, not average benefit and average cost.
- Short-run vs long-run costs and benefits should be considered when making decisions.
International Economics
- International economics explores how nations interact, mainly through trade of goods and services, and flows of money and investment.
- It also examines international issues like migration, resource management, and global conflicts.
GDP Comparison
- Purchasing Power Parity (PPP) adjustments are needed to make fair international comparisons of GDP.
- Countries' relative wealth and price levels affect how much adjustment is needed.
Perfectly Competitive Markets
- Four characteristics of perfectly competitive markets:
- Standardized products. (Consumers are indifferent between products from one firm or another)
- Many buyers and sellers. (No one firm controls market price)
- Resources are mobile (free entry/exit). (Firms can freely enter and exit the market)
- Well-informed buyers and sellers. (Buyers are aware of available opportunities and prices.)
- The Wheat market is a (nearly) perfect example of this type of market, while operating systems markets aren't.
Supply and Demand (Model)
- The model involves:
- Demand Curve
- Supply Curve
- Factors shifting the curves
- Market Equilibrium
- Changes in equilibrium
Basic Concepts of International Trade
- Imports: purchase of goods/services from another country.
- Exports: sale of goods/services to another country.
- Trade balance: the difference between the total value of exports and the total value of imports.
- Trade surplus: exports > imports
- Trade deficit: imports > exports
Relevance of International Trade
- International trade has become more important; the fraction of the US economy engaged in international trade has tripled.
- International trade links societies and people and is important for economic growth, world peace, and development of countries.
The Gains from Trade
- Voluntary trade benefits both parties.
- Producers and consumers benefit when countries specialize in producing what suits their resources and skills best.
Protectionism vs. Free Trade
- Trade can benefit countries (international competition, broader income distribution), but trade can also have some negative effects on certain groups of people or industries within a country, such as decline of lower-skill worker salaries.
World Trade Overview
- Key concepts for the structure and dynamics of trade between countries:
- Gravity model
- Globalization trends
- Changing composition of trade.
Other Important Information
-
The largest trading partners of the US in 2015 were Canada, China, Mexico, Japan, and Germany. The top 20 trading partners accounted for 80% of the value of US trade.
-
Trade within Europe is the largest part of world trade, about 21%. This is due to the nature of the EU (many countries near each other, have eliminated internal trade barriers)
-
Trade with Asia is also large in volume. China is the world's leading exporter.
-
The main types of goods traded are manufactured goods (53%), followed by services (20%), fuels / mining and agricultural products (combined 27%)
-
A 1% increase in the distance between countries is associated with a 0.7% to 1% decrease in the value of trade between the two countries, all else equal.
