In every economy, the key activities revolve around production, exchange, and consumption of goods and services. Scarcity of resources leads to difficult choices regarding how to allocate these limited resources effectively. The economic problems can be summarized into three fundamental questions: 1) What goods and services to produce and in what quantities? 2) How should these goods be produced, considering the balance between labor and technology? 3) For whom are these goods produced, determining the distribution of resources among individuals? The section also highlights the concept of a Production Possibility Frontier (PPF), which illustrates different combinations of goods that can be produced, emphasizing the opportunity cost of choices made by an economy. Understanding these central problems is crucial for optimizing resource allocation and ensuring the economy meets the needs of its population.
