as the price of a good increases, the quantity supplied increases
law of supply
supply refers to the ___
willingness to sell
He credited with attempting to apply rigorous mathematics to economies to turn economies into more of a science than a philosphy
published the "Economics of Industry"
Alfred Marshall
A supply curve is always __ sloping and reflect a _ correlation between quantity supplied and price
upward; direct
what will happen if the supply curve shifts to the right?
it will increase the overall supply curve
What will happen if the supply curve shifts to the left?
it will decrease in the overall supply curve
What will happen if there is a rightward movement shift ALONG, ON, WITHIN the supply curve?
it will increase in the QS
What will happen if there is a leftward movement shift ALONG, ON, WITHIN the supply curve?
it will decrease in the QS only
arises when a volume of product or service in a marketplace has been maximized.
Market Saturation
in a free market, there will be a single price that brings demand and supply into balance, also called the "Market Clearing Price"
Equilibrium
if the price exceeds the equilibrium price
surplus
if the price is below the equilibrium price
shortage
it prevents a price from falling below a certain level. legally mandated minimum price
Price Floor
it prevents a price from rising above a certain level. Legally mandated maximum price
Price ceiling
Shifts in Equilibrium (SUPPLY)
if the demand increases, what will happen to EP and QS?
both EP and QS increases
Shifts in Equilibrium (SUPPLY)
if the demand decreases, what will happen to EP and QS?
both EP and QS decreases
Shifts in Equilibrium (DEMAND)
if the supply increases, what will happen to EP and QD?
The EP decreases and the QD increases
Shifts in Equilibrium (DEMAND)
if the supply decreases, what will happen to EP and QD?
The EP will increases and the QD decreases
they can increase the output without a significant cost or delay
Elastic Supply (PES >1)
suppliers are very unresponsive to the increase of price
Inelastic Supply (PED<1)
when the percentage change in QS is equal to the percentage change in Price
Unitary Elastic Supply (PES = 1)
increase in the demand can be met without change in price
Perfectly elastic supply (PES = ∞ )
the supply is fixed and cannot respond to a change in demand
Perfectly inelastic supply (PES = 0)
Midpoint method for Elasticity
Assume that an apartment rents for Php 650 per month and, at that price, 10,000 units are rented. When the price increases to Php 700 monthly, 13,000 units are supplied into the market. By what percentage does apartment supply increase? What is the price elasticity
|MP| = 3.5 Elastic
the transformation of resources (or inputs) into commodities (or outputs)
Production
_ are economic resources that can be used to produce goods and services, while _ are the outcomes of the production process
Inputs; Outputs
refers to the period of time over which the amount of some inputs, ‘fixed inputs’ ‘variable inputs’ – production is constant
Short-run
refers as the time period during which all factors of production can be varied. All the factors are variable in the __
Long-run
a direct payment with monetary value made while running a business. (e.g., Salaries, Rent, Utilities, Raw Materials, Taxes)
Explicit Costs
a.k.a. Economic Costs are costs equal to what a firm must give up to achieve something in return. These are not recorded, nor do they have a specific reciprocal when used.
Implicit Costs
costs directly involved in developing, manufacturing, or releasing products to market
direct costs
costs that are not directly related to a specific cost object like a function, product, or department. They are costs that are needed for the sake of the company’s operations and health
Indirect costs
Occurs when a firm has an economic profit less than zero. This is where the firm is not earning enough to cover opportunity costs; resources could have higher returns somewhere els
Economic Loss
This means that the firm can also cover more than its opportunity cost
Pure/Positive Economic Profit
Revenue minus all explicit and implicit costs results in a breakeven.
Zero Economic Profit
minimum profit necessary to keep a firm in operation
Normal Profit
ceteris paribus, if one factor of production is increased while other factors are held constant, the marginal output per unit will eventually diminish
The Law of Diminishing Marginal Returns
Curves that represent different combinations of the two variable inputs that can produce the same level of output. It represents a specific level of output
Isoquants
measures the rate at which one input can be substituted for the other while keeping output constant. It is the slope of the isoquant curve and represents the trade-off between the two inputs.
