increase; decrease; demand

The gap between quantity supplied and quantity demanded is usually closed over time by the

The added expense of producing one more unit of output is called the

marginal cost.

The extra amount of output a business can generate by adding one more hour of labor is called

marginal product.

As the market price of a good rises, businesses will respond by producing more of that good because
