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
