A durable good is a type of product that delivers utility over a long period, typically three years or more. These goods are contrasted with non-durable goods, which are consumed quickly. Durable goods play a significant role in both individual consumption and national income accounting.
Historical Context
The concept of durable goods dates back to early economic theories. Historically, the classification of goods into durable and non-durable became essential with the advent of industrialization and mass production, which increased the variety and availability of such products.
Key Events
- Industrial Revolution (1760-1840): Mass production of durable goods began, making items like machinery and home appliances more accessible.
- Post-World War II Boom: Significant increase in the production and consumption of durable goods like automobiles and household appliances.
- Digital Age (1990s-Present): Introduction of electronics as a major category of durable goods.
Types/Categories of Durable Goods

Detailed Explanations
Economic Importance
Durable goods are significant indicators of economic health. High demand for durable goods suggests consumer confidence and financial stability, while a decrease can signal economic downturns.
Mathematical Models
Economists often model the consumption of durable goods using the Permanent Income Hypothesis and Life-Cycle Hypothesis, which predict consumer behavior over time.
Consumption Model Example:
Where:
- \(C_t\) = Consumption of durable goods at time t
- \(Y_t\) = Disposable income at time t
- \(D_{t-1}\) = Stock of durable goods from the previous period
- \(a, b\) = Coefficients indicating the sensitivity of consumption to income and existing stock
