Economics, Strategy, Globalization Flashcards
Focuses on the behavior and purchasing decisions of individuals and firms
microeconomics
the quantity of a good or service that consumers are willing and able to purchase at a range of prices at a particular time
demand
occurs when demand variables, other than price, change
Demand curve shift
Goods (i.e. bread, potatoes) whose demand gos up as consumer income (wealth) goes down
Inferior goods
Ed=% Change in quantity demanded/% Change in price=(Q2-Q1)/Q1/(P2-P1)/P1
Price Elasticity of demand
Demand is elastic–sensitive ot price changes
When Price Elasicity of Demand is >1
Demand is unitary–not sensitive or insenstitive ot price changes
When Price Elasticity of Demand is =1
Demand is inelastic–not sensitive to price changes
When Price Elasticity of Demand
=(Percentage change in quantity demanded)/(Percentage cahnge in income) Positive for normal goods, negative for inferior goods)
Income Elasticity of Demand
=(Percentage change in the quanitty demanded of Product X)/(Percentage change in the price of Product Y) –If positive, goods are substitutes –If negative, goods are complements –if 0, goods are unrelated
Cross Elasticity of Demand
As the price of a good falls, con sumers will use it to replace similar goods
Substitution effect
As the price of a good falls, consumers can purchase more with a given level of income
Income effect
as a person increases consumption of a product - while keeping consumption of other products constant - there is a decline in the marginal utility that person derives from consuming each additional unit of that product.
Law of Diminishing Marginal Utility
A curve used in economics which shows how consumers would react to different combinations of products –used to evaluate marginal utility
Indiferrence curves
represents the combinations of goods and services that a consumer can purchase given current prices with his or her income
Budget Constraint
The amount of income that individuals receive and have available to purchase goods and services (after receiving transfer payments from the government andpaying taxes)
Personal Disposable income
Depicts the relationship between changes in personal disposable income and consumption C=C0+(C1*YD)
Consumption function
An economic term for the amount that consumption changes in response to an incremental change in disposable income
Marginal Propensity to Consume (MPC)
The percentage of additional income that is saved
Marginal Propensity to Save (MPS)
The percentage change in the quantity supplied of a product resulting from a change in the product price =(% change in quanitty supplied)/(% change in price)
Elasticity of Supply
The price at which all the goods offered for sale will be sold (quantity demanded=quanitty supplied)
Equilibrium Price
A specified maximum price that may be charged for a good, usually established by a government–if set below equilibrium, will cause shortages because suppliers will spend time producing other goods
Price ceiling
A specified minimum price that may be charged for a good, usually establsihed by a government–if set above equilibrium, will cause surplus
Price floor
Used to describe damange to common areas that is caused by the production of certain goods (ex. pollution)
Externalities
Fixed cost per unit of production –decreases as more units are produced
Average fixed cost (AFC)
Total variable costs/ # units produced -Initially stays constant until the inefficiencies of pdoucing in a fixed-size facility cause variable costs to begin to rise
Average variable cost (AVC)
The cost of producing one extra unity -initially decreases then beginsto increase due to ineffiencies
Marginal Cost (MC)
Total costs/# units produced –behavior depends on the makeup of fixed and variable costs
Average Total Cost (ATC)
In LR, output increases in same proportion as increases in production
Constant returns to scale
in LR, output increases by a greater proportion as increases in production
Increasing returns to scale
In LR, output increases by a smaller proportion than increases in production factors
Decreasing returns to scale
The amount of profit necessary to compensate the owners for their capital and/or managerial skills–just enough to keep a firm in business in the LR
Normal profit
the amount of profit in excess of normal profit–does not exist in a perfectly competitive market in the LR
Economic Profit
the additional revenue received from the sale of one additional unit of product
Marginal revenue
the additional cost incurredfrom the production of one additional unit of product
Marginal cost
the additional output obtained from employing one additional unit of a resource (ex. one more worker)
Marginal product
the change in total revenue from emplopying one additional unit of a resource
Marginal revenue product
=Marginal Revenue Product/ Marginal Product
Marginal revenue per-unit
The price of all goods and services produced bya domestic economy for a year at current market prices
Nominal Gross Domestic Product (GDP)
The price of ALL goods and services produced by the economy at a price level adjusted (constant) prices (i.e. with effects of inflation eliminated)
Real GDP
the maximum amont of production that could take place in an economy without putting pressure on the general level of prices
Potential GDP
difference between potential GDP and real GDP –if positive, means there are unemployed resources –if negative, means that the economy is running above normal capacity
GDP gap
GDP minus depreciation
Net Domestic Product (NDP)
The price of all goods andservices produced by labor and property suplied by the nation’s residents
Gross National Product (GNP)
Curve depicting the demand of consumers, businesses, and government as well as foregin purchasers for the goods and services of hte economy at different price levels
Aggregate demand curve
As price levels increase, nominal interest rates increase causing a decrease in interest sensitive spending (i.e. homes, automobiles, appliances)
Interest Rate Effect
When price levels increase, the market value of certain financial assets decreases cauusing individuals to have less wealth and therefore they reduce their consumption
Wealth effect
When domestic price levels increase relative to foreign currencies,foreign products become less expensive causing an increase in imported goods and a decrease in exported goods, decreasing the aggregate demand for domestic products
International purchasing power effect
Occurs when the output level of the economy creates just enough spending to purchase the entire output
Equilibrium GDP
Refers to the fact that an increase in spending by consumers, businesses, or hte government has a multiplied effect on equilibrium GDP
The multiplier
a fluctuation in aggregate economic output that lasts for several years
business cycle
businesses that perform better in periods of expansion and worse in periods of recession
cyclical businesses
