Document Summary

Rtopic 9 use of supply and demand. Goods and services are scarce relative to what people want. Resources to produce goods and services are limited. Decisions on what to produce, how, and for whom inevitably involve trade-offs. Free market system automatically makes these trade-offs based on what is socially optimal, not basone on what is good for individuals. Only free market equilibrium meets both conditions. Naturally occurring equilibrium is the only place where both conditions are satisfied. Mu = mc condition and maximization of social value. Mu = marginal utility = marginal happiness from consumption. Mc = marginal variable cost of production. Variable costs faced by producers reflect society-wide opportunity costs. They are prices set in factor markets where alternative users bid for scarce resources, such as labor and energy. Serve as a signal for efficient allocation of resources across product markets. Mu in any market marginal social benefit. Mc in any market marginal social oc (related to foregone happiness!)
