Consider an economic model that seeks to analyze the impact of a change in consumer confidence on overall economic output. The model includes variables such as consumer spending, investment, and government expenditure. Economists collect historical data on these variables to calibrate the model and validate its predictions. Now, If the economists discover that the model consistently underestimates the actual increase in output following a surge in consumer confidence, even after accounting for all known factors, the model:

A team of economists is constructing a sophisticated macroeconomic model to simulate the effects of various fiscal policies on long-term economic growth. The model incorporates numerous equations, variables, and intricate feedback loops. After extensive calibration and validation, the economists find that the model's results are highly sensitive to even minor changes in the initial values of certain key parameters, such as the savings rate and the rate of technological progress. Specifically, small variations in these parameters lead to drastically different predictions about the long-term growth trajectory of the economy. The economists also observe that the model exhibits chaotic behavior under certain conditions, with unpredictable fluctuations in output and employment. Given these findings, the economists are most likely to conclude that:

Study Notes
Introduction to Economics
- Economics is the study of how societies manage scarce resources to produce goods and services, and distribute them among individuals.
- This stems from the human need for unlimited wants with limited resources.
- Economics investigates what is produced, how it is produced, its purpose, and who makes these decisions.
Economics and Markets
- Economics is derived from the ancient Greek word "oikonomia."
- This word is formed by two other words, oikos and nomos, meaning "house" and "custom/law," respectively.
- Microeconomics focuses on the management or administration of individual households.
- Macroeconomics focuses on the management or administration of nations.
Market vs. Centrally Planned Economies
- Market Economy: Resources are allocated through decentralized decisions of firms and households interacting in markets.
- Centrally Planned Economy: Resources are allocated through the decisions of a central authority, determining production levels, factors of production, and distribution.
Markets
- A market is a mechanism through which buyers and sellers interact to set prices for goods and services.
- The price system solves the problems of consumption, production, and distribution.
- Market prices reflect the value a product has to consumers and the resources used to produce it
Adam Smith's Invisible Hand
- Adam Smith observed that households and firms act as if guided by an "invisible hand" in the market.
- The invisible hand operates through the price system.
- Interactions of buyers and sellers determine prices, reflecting both the value of the good for buyers and the cost to produce it.
- This self-interest in the market leads to maximizing economic welfare for society.
- This market system can lead to efficiency in resource allocation.
Mixed Economies
- Most modern economies are mixed, combining market mechanisms with some government intervention.
- Government intervention may be required for:
- Redistribution of income
- Addressing market failures
- Macroeconomic policies
Economic Models
- Economists play two roles:
- Scientists to explain the world
- Consultants to improve the world
- The scientific method is used to develop and test theories - Observation leads to theories. - Data is then collected to verify or refute theories. - The method must be repeatable under similar conditions.
- Economic models are simplified descriptions of reality using assumptions. To be useful assumptions must be demonstrably testable.
Characteristics of Economic Models
- Understandable & manageable
- Based on reasonable & realistic assumptions
- Testable through empirical analysis.
- Typically composed of diagrams and equations
Economic Variables
- Economic models use variables that represent aspects of the economy or outcome of behavior.
- Endogenous variables are determined by relationships within the model.
- Exogenous variables are determined outside the model.
- Flow variables are measured per unit of time (e.g., income).
- Stock variables are measured at a specific point in time (e.g., wealth).
- Nominal variables are expressed in current prices.
- Real variables are expressed in constant prices.
Analysis Types
- Positive analysis: Studies economic consequences of policies based on specific assumptions without determining if the outcomes are desirable or not.
- Normative analysis: Analyzes whether an economic policy is useful or not, considering both the policy's effect and a subjective view about the characteristics of the economic system.
Circular-Flow Diagram
- The circular-flow diagram depicts the transactions in an economy, showing flows around a circle.
- It illustrates the flow of goods and services, factors of production, and money between households and firms.
Microeconomics
- Focuses on the decisions of individual economic agents (households and firms) and their interactions in specific markets.
- Explains how much an individual consumes of a good, the output of a company, and why prices vary.
Macroeconomics
- Examines the economic phenomena affecting the entire economy.
- Factors of concern include unemployment, changes in price levels, economic growth, and government policies.
Relationships Between Micro and Macroeconomics
- Micro and macroeconomics share common concepts and methods.
- Microeconomics concentrates on individual actors and markets, while macroeconomics focuses on aggregate concepts and the overall economy.
