Course Overview

This course provides an introduction to microeconomic principles with a focus on applications in the food and fiber sector of the U.S. economy. Students will learn how microeconomic forces influence decision-making in agribusiness and related industries.

Course Objectives

• Apply the economic way of thinking, including marginal analysis, to decision-making in agribusiness and small business operations.

• Evaluate how markets allocate resources through the interaction of demand and supply.

• Analyze the impacts of market intervention and non-market forces (such as externalities, public goods, and government intervention) on market outcomes and efficiency.

• Compute and interpret measures of responsiveness of demand and supply to changes in determinants (e.g., own-price, cross-price, and income elasticities).

• Assess the implications of different market structures (monopoly, monopolistic competition, oligopoly, perfect competition) for efficiency, profitability, and government oversight.

• Illustrate differences in firm decision-making in factor markets versus goods and services markets.

Key Microeconomic Concepts Covered

Scarcity, Choices, and Opportunity Cost

Scarcity forces individuals and firms to make choices about how to allocate limited resources. Every choice involves an opportunity cost, which is the value of the next best alternative foregone.

• Marginal Analysis: Decision-making based on weighing additional benefits against additional costs.

• Optimization: Choosing the best feasible option given constraints.

• Production Decisions: What, how, how much, for whom, and when to produce.

Demand and Supply

Markets allocate resources through the interaction of buyers and sellers. The law of demand and law of supply describe how prices and quantities are determined.

• Demand: The quantity of a good or service consumers are willing and able to buy at various prices.

• Supply: The quantity of a good or service producers are willing and able to sell at various prices.

• Market Equilibrium: The price at which quantity demanded equals quantity supplied.

Example: If the price of wheat rises, farmers may supply more wheat, but consumers may buy less, leading to a new equilibrium price and quantity.

Economic Efficiency, Government Intervention, and Market Failure

Markets are efficient when resources are allocated to their highest-valued uses, but sometimes government intervention is necessary to correct market failures such as externalities and public goods.

• Externalities: Costs or benefits of a market activity borne by a third party (e.g., pollution).

• Public Goods: Goods that are non-excludable and non-rivalrous (e.g., national defense).

• Government Intervention: Taxes, subsidies, price controls, and regulations to improve market outcomes.

Elasticity

Elasticity measures how much quantity demanded or supplied responds to changes in price or other factors.

• Price Elasticity of Demand: $\varepsilon_d = \frac{\%\ \text{change in quantity demanded}}{\%\ \text{change in price}}$

• Price Elasticity of Supply: $\varepsilon_s = \frac{\%\ \text{change in quantity supplied}}{\%\ \text{change in price}}$

• Cross-Price Elasticity: $\varepsilon_{xy} = \frac{\%\ \text{change in quantity demanded of good x}}{\%\ \text{change in price of good y}}$

• Income Elasticity: $\varepsilon_I = \frac{\%\ \text{change in quantity demanded}}{\%\ \text{change in income}}$

Example: If the price of beef increases by 10% and the quantity demanded falls by 20%, the price elasticity of demand is $-2.0$ (elastic demand).

Market Structures

Market structure affects firm behavior, efficiency, and the need for government regulation.

• Perfect Competition: Many firms, identical products, free entry and exit.

• Monopoly: One firm, unique product, high barriers to entry.

• Monopolistic Competition: Many firms, differentiated products, some barriers to entry.

• Oligopoly: Few firms, interdependent decision-making, barriers to entry.

Example: The wheat market is close to perfect competition, while local utilities are often monopolies.

Factor Markets

Firms make decisions about hiring labor and purchasing other inputs in factor markets. The demand for factors is derived from the demand for the goods and services they help produce.

• Labor Market: Wages are determined by supply and demand for labor.

• Other Factors: Land, capital, and entrepreneurship are also allocated through markets.
