Economics of Decision Making

Economic Value of Benefits and Costs

• Monetary benefits are often difficult to quantify, exemplified by deciding whether to watch a specific film.
• Economists define benefits as the willingness to pay, representing the maximum amount a person would pay for an action.
• Different individuals have varying willingness to pay based on personal preferences and enthusiasm, e.g., a Spiderman enthusiast versus a romantic comedy fan.
• Costs encompass explicit costs (actual money spent) and opportunity costs (value of the best alternative forgone).
• Opportunity cost is a vital concept in economic analysis, linking scarcity with decision-making.
• Individuals may perceive opportunity costs differently, resulting in distinct choices based on the value of alternatives sacrificed.

Income Distribution and Inequality

• Individual income stems from wages and asset ownership (land, buildings, corporate equity), demonstrating disparities in wealth distribution, as seen in Brazil and Denmark.
• Income distribution can be altered through government taxes, aiming to reduce inequality in wealth and power.
• Socioeconomic incentives differ based on income levels, influencing saving behaviors in low-income individuals and investment decisions in high-income individuals.

Behavioural Economics

• While rationality is a cornerstone of standard economics, it doesn't always predict human behavior effectively.
• Behavioral economics examines psychological and sociological factors influencing decisions, highlighting phenomena like loss aversion and consumer overspending.
• Rationality implies individuals utilize all available information when making decisions, but this is challenged by observable deviations in behavior.

Market Creation and Resource Allocation

• Markets can develop in unconventional settings, as seen in POW camps where trading emerged naturally to address resource scarcity, leading to complex exchanges.
• Prices fluctuate based on supply and demand, guiding resource allocation in production (e.g., beef versus pork during health crises).

Macroeconomic Concepts

• Gross Domestic Product (GDP) represents total economic output but fell post-2007 during a global recession.
• The aggregate price level averages price changes, indicating inflation when rising.
• The unemployment rate is a measure of job-seeking individuals within the labor force, not accounting for those outside this group.

Consumer Price Index (CPI)

• The CPI tracks changes in living costs through a 'shopping basket' of goods, calculated using index numbers weighted by expenditure categories.
• Categories such as food, housing, and transport are weighted differently based on consumer spending patterns, influencing how price changes affect the overall CPI.

Weights of Goods in CPI

• Weights in the CPI reflect consumer expenditure (summed to 1), showing that significant price changes in high-weight items (like food) have a greater impact on the CPI than low-weight items (like alcoholic beverages).
