Apple produces iPhones and iPads; two different products; however, it can only produce a limited number of each product because of its scarce resources; physical capital (plants and equipment) and people (labor), for example. Countries, like businesses or consumers, also have limited resources to produce goods and services for their citizens. These resources might include labor, arable land, and weather. The PPF curve shows where production and allocation are most efficient and where scarce resources are most efficiently utilized. In your own words, address the following requirements. Be sure to exceed a minimum of 125 words for each requirement to ensure thorough depth and detail is utilized in demonstrating your understanding of the answer. Describe what the PPF Curve represents and explain the relationship between the vertical axis representing one good or service and the horizontal axis representing another good or service. Discuss why countries should avoid producing inside of the PPF curve. Explain how a country can achieve production outside the PPF curve and provide examples. Explain why different countries might have different PPF curves for the same good and how each country might help the other, providing examples
