In economics, zero often signifies a neutral or balanced state, where there is neither a surplus nor a shortage of resources, prices are stable, and the economy is operating at its potential.

When the inflation rate is zero, it means that the general price level of goods and services remains unchanged over time, indicating a stable economic environment.

Zero unemployment is an ideal state where everyone who wants to work has a job, but it is often unattainable due to factors like frictional and structural unemployment. Full employment, on the other hand, is a more realistic target, where unemployment is minimized to a natural rate.

Zero economic growth, also known as economic stagnation, occurs when the real gross domestic product (GDP) of a country remains unchanged over time, resulting in a lack of economic progress and development.

Price controls are government-imposed regulations that set maximum or minimum prices for goods and services, aiming to stabilize prices and prevent inflation.

Zero interest rate policy is a monetary policy tool used by central banks to stimulate economic growth by making borrowing more attractive and encouraging investment.

Zero population growth, where the birth rate and death rate are equal, does not directly impact economic growth, as it does not affect the size of the labor force or the overall demand for goods and services.

When a firm has zero marginal cost, it can produce additional units of output without incurring any additional costs, allowing it to offer products at a very low price to gain market share.

Zero externalities occur when the production or consumption of a good or service does not impose any costs or confer any benefits on third parties, resulting in an efficient allocation of resources.

Zero-sum game theory is a mathematical model that assumes that the gains of one party in an economic interaction are exactly offset by the losses of the other party, resulting in no overall change in wealth.

In a perfectly competitive market, the price of a good or service is determined by the forces of supply and demand, resulting in zero economic surplus, where consumers and producers are indifferent between buying and selling.

Zero-based budgeting is a budgeting process where each budget cycle begins with a zero base, and all expenses must be justified and approved, ensuring that resources are allocated efficiently.

Zero poverty, while challenging to achieve, is a fundamental goal of economic development, aiming to eliminate extreme poverty and improve the living standards of the poorest populations.

Zero-rating is a practice where internet service providers offer free access to certain websites or services without charging users data fees, aiming to promote digital inclusion and access to essential online resources.

Zero-sum thinking, which assumes that one party's gain is always another party's loss, can hinder economic growth and development by discouraging cooperation, innovation, and mutually beneficial economic interactions.
