πŸ“š Quick Study Guide

    πŸ“ˆ Definition: A Production Possibility Frontier (PPF) shows the maximum possible output combinations of two goods or services an economy can achieve when all resources are fully and efficiently employed. 🍎 Assumptions: Fixed resources, fixed technology, full and efficient resource utilization, and production of only two goods. πŸ“‰ Shape: Usually concave (bowed outwards) due to the law of increasing opportunity cost. Linear PPFs indicate constant opportunity costs. πŸ’° Opportunity Cost: The amount of one good that must be sacrificed to produce one additional unit of another good. It's represented by the slope of the PPF. 🎯 Points on the PPF: Represent efficient production. Points inside the PPF represent inefficient production, and points outside are unattainable with current resources and technology. βš™οΈ Shifts in the PPF: An outward shift represents economic growth, caused by increases in resources or technological advancements. πŸ“Š Formula for Opportunity Cost: Opportunity Cost of Good A = $\frac{\text{Change in Good B}}{\text{Change in Good A}}$
