Chapter 1 - The Art and Science of Economic Analysis

  • Economics is all about making decisions, and you make economic decisions on a daily basis, such as whether to work part-time or focus on your education. Taking an accounting or history course, bringing and choosing a simple snack over another, would lead to the issue of demands being essentially limitless, but resources to fulfill them are finite.

    • The term resources refer to inputs or factors of production, used to produce the goods and services that people want; resources consist of labor, capital, natural resources, and entrepreneurial ability.

  • The resources, or elements of production, are utilized to create the commodities and services that people desire. Because resources are limited, goods and services are scarce.

  • Labor, capital, natural resources, and entrepreneurial aptitude are the four basic kinds of resources. Human effort, both physical and mental, is defined as labor. Labor is derived from a more basic resource called time. Nothing is accomplished if there is not enough time. Time for alternate uses can be allocated, for which it can be sold or spent upon.

    • The term Human capital refers to the information and skills that individuals gain in order to boost their production, such as the surgeon's understanding of human anatomy, the cab driver's knowledge of city streets, and your understanding of economics

  • Natural resources are split into two categories: renewable and nonrenewable. If used sparingly, a renewable resource can be used eternally. As a result, if destroyed trees are replanted to ensure a continuous supply, wood is a renewable resource. If given enough time and space, the air and rivers are renewable resources. It's time for them to get rid of whatever contaminants they've accumulated. Biological resources, in general, include Fish, game, cattle, woods, rivers, groundwater, grasslands, and soil are all renewable resources if they are managed properly appropriately managed.

  • Due to the matter of which goods and services are made with limited resources, they are in short supply. A good or service is scarce if the number of people who want it exceeds the number of individuals who can get it for free.

  • We must constantly pick between things and services since we cannot have all we want. We must pick between more pleasant ways of life to make more comfortable accommodations such as better food, finer clothes, more dependable transportation, quicker computers, and so on. In a world of scarcity, we must forgo some goods and services while making decisions.

  • Households, companies, governments, and the rest of the world are the four categories of economic decision-makers. How an economy's resources are distributed is determined by their interaction. The spotlight is on households. Households want the products and services that are produced because they are consumers. Households, as resource owners, provide companies, governments, and the rest of the world with labor, capital, natural resources, and entrepreneurial aptitude.

    • The term entrepreneurial ability refers to the imagination required to develop a new product or process, the skill needed to organize production, and the willingness to take the risk of profit or loss.

  • Firms, governments, and the rest of the world require the resources that households provide, and these resources are then used to provide the products and services that households desire.

  • Foreign families, foreign companies, and foreign governments that supply resources and goods to US markets and demand resources and products from US markets make up the rest of the world.

  • Markets are the places where buyers and sellers meet to exchange goods and services. Markets influence price, quantity, and quality by bringing the two sides of trade together. Supermarkets, department stores, shopping malls, and yard sales are all examples of marketplaces. However, markets often include alternative means of communication between buyers and sellers, such as classified advertisements and bartering. These market processes give data on the number, quality, and price of items available for purchase.

    • The term circular-flow model refers to a diagram that traces the flow of resources, products, income, and revenue among economic decision-makers, as shown on the image attached on the right.

  • Individuals rationally pick what they believe to be in their best interests, according to a basic economic premise. Economists define rationality as people trying to make the best decisions they can given the time and knowledge they have. People may not be able to predict which option will turn out to be the greatest. They just choose the options that they believe would provide the most enjoyment and fulfillment. In general, rational self-interest means that each person attempts to maximize the expected gain for a given cost or reduce the expected cost of attaining a given benefit.

    • The term economic theory, or economic model, refers to a simplification of economic reality that is used to make predictions about the real world.

  • Economists employ scientific analysis to create hypotheses or models that assist explain the economic activity. A theory, or model, such as the circular flow model, encapsulates the key features of the topic under investigation without having to explain every detail and interrelationship. In fact, adding additional features to a theory may make it more cumbersome and therefore less helpful.

  • A good theory aids us in comprehending a complex and perplexing reality. Our brain might get congested with facts, one heaped on top of the other, like in a cluttered closet, if we don't have a theory of how things function. A good theory may be thought of as a mental closet organizer. A good theory provides a framework for organizing, storing, and comprehending data.

  • The majority of dispute among economists is about normative issues, such as the proper role of government, rather than positive analysis. Although many theoretical questions remain unsolved, economists usually agree on the most basic theoretical principles—that is, positive economic analysis.

  • Economists employ theories, or models, to assist them to understand the consequences of economic changes, such as price or income changes, on individual decisions and how these choices influence specific markets and the economy as a whole. To study an economic problem, economists use the scientific method, which includes

    • (a) formulating the question and identifying relevant variables

    • (b) specifying the assumptions under which the theory operates

    • (c) developing a theory, or hypothesis, about how the variables relate

    • (d) testing that theory by comparing its predictions with the evidence

  • A hypothesis may not be flawless, but it is helpful if it predicts better than rival hypotheses.

  • Positive economics seeks to understand how the economy operates. Normative economics is more concerned with how the economy should function from someone's perspective. Those who are not cautious may fall victim to the fallacy of association as causation, the composition fallacy, and the error of disregarding secondary effects.

  • Microeconomics is concerned with decisions made in families, firms, and governments, as well as how these decisions influence specific markets, such as the market for used automobiles. The rational self-interest of the decision-maker guides the decision-making process. The choice usually necessitates the use of time and information, both of which are limited and important.
