Summary

The theory of demand is a fundamental concept in agriculture economics that helps understand the behavior of buyers and the market. It involves the study of demand definition, different types of demand, demand schedule and curve, the law of demand and its determinants, extension and contraction vs increase and decrease in demand, elasticity of demand, Engel's law of family expenditure, and consumer's surplus. Understanding the theory of demand is crucial for making informed decisions in agricultural economics.

Analogy

Understanding the theory of demand in agriculture economics is like understanding the preferences and behavior of customers in a restaurant. Just as the restaurant owner needs to know what dishes are in demand, how prices affect customer choices, and how changes in income impact spending patterns, farmers and agricultural economists need to understand the theory of demand to make informed decisions about what crops to grow, how much to produce, and how to price their products.
