Macroeconomics and Microeconomics I. Economics is the science of allocating
scarce resources among different and competing choices and utilizing them to best satisfy human wants. It is a study of how to get the most satisfaction for a given amount of money or to spend the least money for a given want or need. The study of economics is based upon the principle of scarcity of resources. Resource scarcity states that the inputs needed to make products are not available in unlimited supply.

Macroeconomics and Microeconomics A. Macroeconomics is the study of
the economy as a whole. It is comprised of all the choices made at the microeconomic level. 1. Macroeconomics looks at the effects of
changes in the production of goods and services and employment and how they interact to influence economic performance on a broad scale. The actions of individuals, businesses and government entities all influence macroeconomics.
![Page 9: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/9.jpg)

Macroeconomics and Microeconomics 2. Concepts related to macroeconomics
include: a. Gross Domestic Product (GDP) is the market
value of all goods and services produced within a country in one year.
b. Total Supply is the total amount of goods and services produced during a defined period of time.
c. Total Demand is the total amount of spending on goods and services during a defined period of time.
![Page 10: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/10.jpg)

Macroeconomics and Microeconomics
d. Inflation is a sustained increase in the average price of goods and services within the entire economy. Deflation is a sustained decrease in the average price of goods and services within the entire economy.
e. Governmental policy that relates to the amount of money (cash) available in the economy and policy that relates to taxes and government spending.
![Page 11: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/11.jpg)
11
Macroeconomics and Microeconomics B. Microeconomics is the study of
individual economic choices. 1. Every person makes choices about how to spend
his or her money. They decide on how to allocate a scarce resource (money) in return for a perceived benefit that the allocation will bring.
2. The common denominator that individuals use in making these choices is price. Any economic system must have a method of establishing prices. Once these prices are established, individuals are able to make choices about how to allocate their resources.
![Page 12: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/12.jpg)

Macroeconomics and Microeconomics 3. Concepts related to microeconomics include:
a. Markets and prices give individuals the opportunity to buy and sell goods. Markets are the locations where this interaction occurs. Prices are the amounts of money that people pay for a good or service.
b. Supply and demand is affected by business organizations and consumers. Governmental policies can sometimes affect supply and demand.
c. Competition is determined by the number of buyers and sellers in particular markets.
d. Business failures occur due to inadequate competition, lack of access to reliable information, not enough demand for goods, and other reasons.
![Page 13: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/13.jpg)

Law of Supply II. The law of supply states that
when the price of a product is lowered, with no change in other factors, less of the product will be supplied. A. Supply is the quantity of a product or
commodity that sellers are willing to provide to the market at a given price.
![Page 14: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/14.jpg)

Law of Supply 1. The law of supply
principle can be illustrated on a graphic. a. As the law of supply
states, when price is raised, supply (the quantity of products or commodities) will increase.
b. In the same way, when price is lowered, supply (the quantity of products or commodities) will decrease.

17
Law of Supply B. Several factors influence supply and
can cause an increase or decrease in supply. 1. Technology affects supply.
a. Generally, technology decreases the cost of production, making it cheaper to produce the product.
![Page 18: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/18.jpg)
18
Law of Supply 2. Costs of production affects supply.
a. When prices of inputs change, the level of production often changes.
b. Generally, producers try to sell products for at least as much as the total cost of all the inputs.
![Page 19: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/19.jpg)
19
Law of Supply 3. Price of other products affects supply.
a. If a farm or agribusiness can produce a different product that is priced higher, it may change production to capitalize on higher profits. For example, if the price of apple butter increased greatly, an applesauce producer might stop producing applesauce in order to start producing apple butter.
b. Sometimes it is unfeasible to shift fixed assets to produce different products. For example, it would be too expensive and difficult to remove a grape vineyard to plant wheat and take advantage of higher wheat prices.
![Page 20: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/20.jpg)
20
Law of Supply 4. Seasonal and cyclical production affects
supply. a. Some cycles of production are uncontrollable
such as the time required for livestock to reproduce or the time needed for plants to bear fruit.
b. Certain nuts, fruits and vegetables are considerably cheaper when "in-season". A food is considered "in-season" during the time that it is ripe and being harvested.
![Page 21: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/21.jpg)
21
Law of Demand III. The law of demand states that
when the price of a product or commodity is increased with no change in other factors, less product will be purchased. A. Demand is the quantity of a product or
commodity buyers are willing to purchase from the market at a given price.
![Page 22: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/22.jpg)
22
Law of Demand 1. The law of demand
principle can be illustrated on a graphic. a. As the law of demand
states, when price is raised, demand (the quantity of products or commodities) will decrease.
b. In the same way, when price is lowered, demand (the quantity of products or commodities) will increase.

25
Law of Demand B. Several factors influence demand
and can cause demand for a product or commodity to increase or decrease. 1. Size of population affects demand.
a. With higher population, more product will be needed.
b. All other things constant, demand is increased as population increases.
![Page 26: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/26.jpg)
26
Law of Demand 2. Tastes and preferences of consumers
affects demand. a. Tastes and preferences change with
time and other factors. b. Weather and climate affects
preferences. For example, soups and stews may be more desired in cold climates while cool drinks may be more desired in hot climates.
![Page 27: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/27.jpg)
27
Law of Demand 3. Income and distribution of wealth
affects demand. a. Generally, higher income results in more
products being purchased. b. More expensive and luxury items are
purchased as incomes increase.
![Page 28: Unit D: Applying Basic Macroeconomic Principles in Agribusiness · 2019. 10. 24. · Unit D: Applying Basic Macroeconomic Principles in Agribusiness Lesson 1: Understanding Supply](https://reader035.fdocuments.us/reader035/viewer/2022071103/5fdd68a4e0733d3d801624e7/html5/thumbnails/28.jpg)
28
Law of Demand 4. Relative prices of all goods and services affects
demand. a. With a limited budget, decisions to buy an item
directly affects the amount of another item that can be purchased.
b. When the price of a substitute item decreases, consumers will purchase more of the substitute. i. A substitute is a product that is similar to and can
replace another product. ii. For example, a substitute for pistachios would be
almonds. c. When the price of a complement decreases, more of
the item will be purchased. i. A complement is a product that is used together with
another product.

30
Relationship of Supply and Demand B. As supply or
demand changes, the equilibrium price also changes. 1. If the supply curve
shifts left (supply decreases), the price increases.
2. If the supply curve shifts right (supply increases), the price decreases.
