Supply Curve shift factors | Input price change Technology improvements |
What are the two types of monetary policy | Change in taxes (increase or decrease) Change in government spending (increase or decrease) |
Consumer utility maximization fn & What is the equation of the consumer's constraints | Max U = U(X,Y) & Y=Px*X+Py*Y |
Demand Fn for Goods X & Y, for a utility maximizing consumer | Qx = D(Px, Py, I, preference) & Qy=D(Py, Px, I, preferences) |
Quantity Demanded (movement along demand curve) factors | Price Change |
Production Fn | Q = zf(L,M,K) ------------------Key:-------------------- Z = technology L = Land M = materials K = capital |
What is Average Product | Average output per worker |
What is the Average Product equation | (Quantity of output)/(# of laborers) |
What is the Marginal Product of labor | The amount of output produced from hiring one additional worker |
What is the equation for the Marginal Product of labor | MP(L) = (Change in Q) / (Change in # of workers) |
Diminishing Marginal Product | After a certain point the Marginal Product of a new worker will be less than the Average Product. Because after a while there will be too many workers for the workspace. |
The optimal quantity of labor for a firm is where which two curves meet? | Where Marginal Product meets Average Product |
Economic Profit = | Economic Profit = Total Rev - Explicit Cost - Implicit Cost Implicit costs = opportunity cost of running the firm |
Two ways to Maximize Profit | Maximize Quantities Minimize Costs |
Cost Fn = | C = C(W, K) |
Average Cost | (Total Cost) / (Total Quantity) |
Marginal Cost | (Change in Cost) / (Change in Output) |
If MC > AVG Cost the... | Decreasing Returns to Scale |
If MC < AVG Cost = | Increasing Returns to Scale |
