  5. But it does get complicated…

  6. What is Economics? • Study of allocation of scarce resources to highest and best use • Competing demands on and finite supplies of resources determine how resources are allocated • Study of human behavior • Economics is a social science, which means we are studying human beings and their decisions • Economics requires a broad understanding of both physical and social sciences

  7. Resource Scarcity • A resource is an input provided by nature and modified by humans using technology to produce goods that satisfy human desires. • Two key elements here: • Resources have a finite supply (are limited); yes, yes, the sun and wind are not “limited” in the sense that they will be used up; but they must be combined with other scarce resources to be useful • Human wants are not limited; we call this non-satiation. “More is preferred to less.”

  8. Important Characteristics of Resources • Resource are “scarce” • Because resources are scarce, the goods produced from them are scarce as well • How do we distribute resources—determines how we distribute goods and services • Resources have alternative uses • Because of scarcity and alternative uses, trade-offs must be made • Resources have economic value • Because of scarcity and alternative uses, resources have economic value—that is, we must generally pay to use them

  9. Cost-Benefit Principle • Actors should engage in an action if, and only if, the extra benefits from taking the action are at least as great as the added costs • Easy in concept, difficult to implement • What are the added costs of increased asthma from pollution? • What is the value of a human life?

  10. Opportunity Cost • In economics, we are concerned with trade-offs—that is, how much of one good must we give up to get another. We call this opportunity cost • Opportunity cost reflects the value of alternatives that are foregone or sacrificed to choose another alternative • In our land example, the opportunity cost may be the lost value of agricultural production to society for building another subdivision—by building the subdivision, you are giving up the opportunity to grow strawberries • You are giving up current income to get a college degree (hopefully more future income!!)

  11. Other Dimensions of Economics • Time is another important element of economic decisions • Do we use our petroleum/water reserves today or save them for future generations? • Who makes that decision? • Distribution of income/goods is another important element • Who gets access to educational opportunities? Who pays for it?

  12. Thinking at the margin… • Marginal cost-the added cost arising from the production of one more unit of output • Marginal benefit-the added benefit arising from one more unit of consumption

  13. Micro/Macro Economics • Macroeconomics—examines the performance of national/international economies (e.g., inflation, unemployment, interest rates, etc.) • This is what you hear most about on the news • Microeconomics—study of economic decisions at the individual level • How does a firm maximize profits? • What goods are consumers most likely to purchase?

  14. Analyzing Economic Problems • Positive Economics • Normative Economics • Prescriptive Economics

  15. Positive Economics • Deals with “what is” – purely concerned with measurement and reporting • Does not involve value judgments • Ex. – If the government raises the price support for a commodity, does this cause farmers to produce more of that commodity…and by how much?

  16. Normative Economics • Deals with “what should be” • Inherently involves making value judgments—to address these questions, someone must decide what is “good” and “bad” • Ex. – Should government policy guarantee that farmers get a “fair” price for their grain?

  17. Prescriptive Economics • Deals with ways to achieve a desired result. • Involves both positive and normative issues • Ex. – If we want to increase household income of families in the bottom 20% of U.S. incomes, how can we do this in the manner least costly to U.S. taxpayers?

  18. Economic systems must, then, answer: • What do we produce? • How do we produce it? • For whom will it be produced? • When/how will it be consumed?

  19. Common assumptions • Because of the complexity of the real world, we use simplifying assumptions to aid our analysis of questions. For now, the two most common for which you need to be aware are: • Individuals want to maximize their own well-being (or, as we call it, utility) • Firms want to maximize profits

  20. Agriculture Overview • The principles we will discuss apply to all economic problems, but we will focus on agriculture as our centerpiece for analysis • Agriculture is a complex system beginning with natural resources, biological production of food and fiber products, agribusinesses that process and distribute those goods, the public sector that influences the process through policy, and consumers

  21. Agricultural Production • Includes all farms and ranches that grow crops and livestock (usually, but not always, for sale) • Changes in the agricultural production sector have occurred due to technological change, development of markets, and government policy and international trade

  22. Agribusiness • Input suppliers (produce goods and services used in agricultural production) • Processing and distribution

  23. Public Sector • Government policy and government supplied goods • Higher education • Roads, rail, shipping channels • Extension service • Information services

  24. Some example issues • Food availability and safety, nutrition, etc. • Environmental and resource management • Technological advancement and adoption • Globalization and global competition • Risk and uncertainty • Declining farm numbers, rural development • Alternative energy production
