How do humans view their place/role in the environment? (2 definitions)
Holistic: whole system interacts in "web" or "lattice", every action connected
Atomistic:pieces interact with linear cause and effect, little attention to broader effects unless they begin to effect demand
The second half of agriculture development was based on what type of thinking?
atomistic. we started intensification vs extensification. add water, lime, phosphorous: Danger- fallacy of composition
Why is agricultural pollution different from industrial pollution?
Hard to pin-point a source, called "nonpoint-source pollution" the runoff from many farms causes pollution
5 principals of environmental Regulation
1- When parties bear damage, they have incentrive to reduce damages
2- Policy makers can induce any given behavior by imposing a large enogh penatly
3- Policy makers can induce efficient entry and exit by imposing the rule "everyinjurer pays FULL damages"
4- The marginal cost of abatement(cutting back on problem) should be the same across all injurers
5- It is always best to use regulatory instrument focused on actual source of problem, be as direct & flexible as possible
5-
Possible Policy Responses to Environmental Problem
Market Regulation, Economic incentives (taxes or subsidies), legal liability
Types of Environmental Regulation
performance standards(emissions standards), design standards(must use particular equipment), restrictions on input use (ban of DDT), output restrictions, regulation of land use, policy-related restrictions
What is the harvest index? def and %
Increase our efficiency to the maximum possible, each plant can have at most 60% efficiency
What are our Net Primary Production (NPP) dynamics
we have local externalities (your farm's runoff) and pervasive externlities (effects the entire system, eg. using oil to transport everything)
25% of the entire world's resources are used for humans, we are taking up 40% of the land
Neo Malthusian
We have always had theories that we will run out of food, but we always find a way to overcome it. We can keep innovating and changing the rules/boundries of the Earth and we will survive
SAK stated premise
the food system is consumer driver, rather than producer driven. Consumers look for the following attributes: quality, value, convenience, nutrition, wholesomeness
Poultry consumption increased by 62% while beef dropped 27% between 76-89
8 consumer Trends
demographics, working women/convenience, changing eating patters, food safety concerns, food variety, nutrition/obesity concerns, food retailing, agricultural production
Demographics
Consumer trend: decline in pop growth/avg. household size, we have an older population, growth of ethnic groups
Working women/convenience
Consumer Trend: more women in work force leads to time pressure. demand for convenience mixed with higher incomes = ability to pay for convenience
changing eating patterns
Consumer Trend: dining w/family and 3 square meal declining. Individual choice is up, each family member eats what they want. Cheese consumption stayed solid [bc of pizza] while pork declines
48% of our food is eaten away from home, food price index up from $46 to $482
betty crocker vs from scratch
Food safety concerns
consumer trends: food borne diseases, pesticides, GMOs
Nutrition/Obesity Concerns
2/3 of U.S. deaths from heart disease, cancer and stroke.
consumer trend: 30% of Americans are obese, another 34% are overweight
consumer schizophrenia: concern/awareness does not match actual consumptive behavior
Food Variety
consumer trend: 10,000 new products every year
Total product concept = physical attributes + packaging + advertising + brand + convenience
Food Retailing
consumer trend: fewer, bigger supermarkets. one stop shopping
Agricultural Production
consumer trend: more production under contracts, must respond to market needs (fresh, safe, nutritious, convenient, high quality)
Food Economics: we use economic science to explain: (2)
food consumption patterns, behaviors of consumers
Food consumption is determined by:
income, price, taste, preferences
define: demand schedule
a price-quantity relationship, it assumes other things such as income, are constant
demand shift or move along curve: russia put embargo on our wheat
change in quantity demands: move
demand shift or move along curve: economy in slump: income falls
change in demand: shift
demand shift or move along curve: drought reduces crop size
move along curve
demand shift or move along curve: price of substitutes falls:
change in demand: shift
Engel's insight into Food Budget Shares
as income increases, percent of income spent of food decreases.
Elasticites:
n > 1 =
n < 1 =
n < 0 =
luxury
necessity
inferior good
income elasticity in higher for:
foods for which quality is more important and food eaten away from home
nominal price
actual price paid per unit of good
CPI:
consumer price index: an average change in prices for a fixed market basket of goods
inflation
percent change in CPI
real price
the nominal price divided by CPI. a form of "relative price"
real income
consumer income / CPI
relative price
price paid relative to another price paid (p1/p2). aka "real" price
unitary elastic
E=-1
perfectly inelastic
E=0 ( nD=0 ) demand exists at ANY price
transplant heart, water when almost dead from thirst
perfect elasticity
E = infinity
the smallest measurable change in price will result in infinite change in demand
own price elasticity
the percent change in quantity demanded in response to a one percent change in it's own price
cross price elasticities
the percent change in quantity demanded for a range of goods in response to a one percent change in a different (but similar [substitute?]) good's price
what cross price elasticities means (the numbers)
E > 0 : the goods are substitutes
E < 0 : the goods are complements
What do we like to use elasticies?
because they don't use units so it is easier to analyze change
are most food elastic or inelastic?
inelastic. poor households consume inferior goods
What is the US's food budget share?
10%, the lowest of all countries, however lower income houses spend 30%

hunger:
sustained falure to consumer nutrients in sufficient quantity and in proper proportion to sustain normal bodily functions
malnutrition
deficiency of proteins or other key nutrients
overnutrition:
intake of food excess of bodily needs
famine
hunger occurring to a large population over a wide area for a period of time lasting months to years
6 Causes of Hunger
poverty, income problem, logistic access problem, low education problem, inequality of income, poor health
food deficit value equations

25%
Why trade?
specialization, absolute advantage(a country can naturally produce at a lower cost than anywhere else), comparative advantage (when total output can be increased when each country speacializes and trades
Types of trade barriers
trariff vs non tarrif (import quaota, export subsidies, health/safety restrictions)
GATT
Gneral Agreement on Tariffs and trade
Doha Negoatiations
reduce export subsdies, improve market access, and reduce trade-distorting domestic support (along with things about the environment, property rights, etc)
Boxes
Green: permitted, minimal trade distorting payments such as income support (decoupled)
Blue: permitted, min trade-dist. payments because production cannot respond much due to other constraints
Amber: to be reduced: distort production
Red: forbidden, currently nothing is red
effects of trade diversion
trade creation: resources shift from the least to the most efficient
