Economics is the social science that analyzes the administration and utilization of scarce resources to maximize the satisfaction of society's unlimited wants. It encompasses factors of production such as natural resources, labor, physical and human capital, and entrepreneurship. The Production Possibilities Frontier illustrates the potential combinations of goods produced when resources are fully employed. Key economic questions include what goods are produced, how they are made, and how they are allocated within society. Understanding these concepts helps address fundamental economic issues.
