Gross Investment refers to the total expenditure on new capital assets within a specific period. This includes the purchases of machinery, equipment, buildings, and other physical assets that contribute to the productive capacity of an economy. Simply put, gross investment accounts for all new investments in productive assets before accounting for depreciation.
Types of Gross Investment
Fixed Investment
Fixed investment involves the purchase of fixed assets like buildings, machinery, and infrastructure. These assets are essential for long-term production capabilities.
Inventory Investment
Inventory investment pertains to the changes in the stock of unsold goods and raw materials. It reflects the differences between the goods produced and sold within a period.
Importance of Gross Investment in Economics
Gross Investment plays a crucial role in an economy for several reasons:
- Economic Growth: It is a key driver of economic growth, as increased investments in capital assets lead to an increase in production capacity.
- Job Creation: Investments in infrastructure and industries typically generate more employment opportunities.
- Technological Advancement: Investments in new machinery and technology boost productivity and innovation.
Example of Gross Investment
Consider a manufacturing company that spends $1 million on new machinery and another $500,000 on a new factory. The gross investment for this company over the period would be $1.5 million, representing the total expenditure on new capital assets.
Historical Context
Early Development
The concept of gross investment has evolved over centuries as economies transitioned from agricultural based to industrialized. Early theories by classical economists such as Adam Smith touched on the importance of investments in capital.
Modern Economics
In contemporary economics, gross investment is a fundamental concept studied within macroeconomics and national income accounting. The Gross Domestic Product (GDP) of a country comprises the summation of Consumer Spending, Government Spending, Gross Investment, and Net Exports.
Gross Investment vs. Net Investment
While gross investment represents the total expenditure on new capital assets, net investment deducts depreciation from gross investment. The formula can be represented as:
Related Terms

- Depreciation: The reduction in value of capital assets over time due to wear and tear.
- Real Investment: Refers to investment in physical capital, as opposed to financial investment which involves buying financial instruments.
