AGEC 203 Exam 1 Study Questions
Natural Resource Economics
Branch of economics that focuses on resource allocation questions from a societal perspective
What are the 5 factors which will cause demand to shift to a new function?
Change in consumer income, change in population, change in tastes and preferences, change in related product prices, and change in peoples' expectations
Define Marginal Utility
Change in satisfaction from one more equal unit of a good or service
Explain the consumer equilibrium is the regard to consumer satisfaction and expenditures
Consumer equilibrium is when the slope of the indifference curve is equal to the slope of the budget line. Therefore it is the regard to consumer satisfaction and expenditures because its marginal utility and price are equal. MUY1/MUY2 = PY1/PY2 or MUY1/PY1 = MUY2/PY2
Cross Elasticity of Demand Complementary Products
Cross Elasticity is negative as price of y1 goes up, quantity of y2 goes down chips and slasa
Cross Elasticity of Demand Substitute Products
Cross elasticity is positive as price of y1 goes up, this brings about an increase in consumption of y2 chicken and beef
What are the 4 characteristics of firms in a pure competition model?
Homogenous product, no barriers to enter and exit, mobility of factors to produce, and many small producers
Define Aggregate Demand
Horizontal summation of the quantities of a product demanded by all individuals Ina market at a specific price
Factors that mitigate natural resource scarcity
Technology, scale economies, substitution in consumption, improved transportation & trade, conservation
Why are the production stages 1 and 3 considered to be irrational stages?
The firms are to maximize its net earnings over the cost of x1 used, the firm can increase its net revenue by moving into stage 2 from either stage
Define Demand
The schedule which shows the various amounts of a product or service which consumers are willing and able to purchase for a series of prices Ina given market at a given time

when someone consumes more of a commodity
Consumer Equilibrium
when the indifference curve is equal to the slope of the budget line
Demand
a schedule which shows the various amounts of a product or service which consumers are willing and able to purchase for a series of prices in a given market at a given time
Marginal Rate of subsitiution
(Any point on the graph) is the rate at which one good can be substituted for another without a change in the level of satisfaction equals the slope of the indifference curve MRS=change y1/change y2
Reasons for a downward sloping Demand curve
(negative) -diminishing marginal utility -marginal utility per dollar increases as cost per unit goes down -more people can get into the market as price per unit goes down
Price elasticity of demand affected by
-availability of substitutes -number of alternative uses for the product -price of commodity relative to consumer's total expenditures for that type of product -degree of necessity
Factors Affecting Income Elasticity
-level of income -type of product -where measure is made -family residence
Factors affecting aggregate demand
-number of consumers in a market -consumer income (per capita) -tastes, preferences, habits, and fads -price and availability of substitutes -environmental factors
Underlying assumptions for demand theory
-people will maximize satisfaction -individuals have limited incomes -people are aware of all goods & services available to them and are able to make choices -choices are made relative to a given time period

0<E<1
Howe's 8 major resource issues
1) Finite Supply 2) Location of Resource Supply 3) Shift towards nonrenewable 4) over-exploitation of select resources 5) Decline in environmental services 6) Global commons 7) Decreasing Quality of Services 8) Market failure
Pure Competition
1) Homogenous product 2) No barrier to entry or exit 3) Mobility of factors of production 4) Many small producers
Monopolistic Competition
1) Many sellers of product 2)each firm's product (or service) can in some way be distinguished from that of other producers 3) numerous good substitiutes for product 4) some mobility of factors of production
Oligopoly
1) small numbers of producers 2) high degree of product differentiation 3) the supply of one firm affects the total market supply 4) there are barriers to entry and exit 5) products 6) production factors quite rigid
Why economists like pure competition
1)P=MR No -> Firms controls the market 2)Firms produce at P=MC 3)Firms MC=min ATC (produce at lowest ATC) 4)Lowest opportunity cost of resources to produce the output
Define Demand vs. Quantity Demanded
A change in demand is when the shoe curves shifts, and a change in quantity demanded is movement along the demand curve due to a change in price
