Production requires combining factors of production - land, labor, capital and entrepreneurship. A short-run production function uses existing capital and labor, while a long-run function allows installing new capital. Labor refers to human effort in production and is determined by population, participation rates, and efficiency. Capital consists of man-made wealth yielding income and plays a vital role in modern production. Entrepreneurship involves starting businesses, identifying opportunities, and organizing resources to produce goods and services for profit. Together these factors of production are essential for economic growth.
