hedonic regression
Free rider
Not worrying about collective interest.
Hope everybody will
People who don’t pay but benefit anyway
no effort
Factors to concider for vehicle uses ;
(Is it going to perform well)
Is it going to be drivable
Is it going the perform well in a cold country
Is it price competitive
How economical is it to use
What is the purchase cost
What is the operation cost
If your fuel has very low energy content, and to travel the same distance you now need a much larger fuel tank.
Not desirable to have a large tank because it reduce your payload capacity
How frequently do I need to refuel
How reliable is the fuel supply
Induced demand
Refers to the idea that increasing roadway capacity encourage more people to drive, even though it fails to reduce congestion.
By adding roadway capacity, you create more traffic and congestion because people will ahve more incentive to use their vehicles.
Stage #1 of demographic transition
Preindustrial
- CBR = CDR
- High death rate
- High birth rate
What is envrionmental injustice
the disproportionate pollution burdens in areas primirily inhabited by disadvantaged ethnic groups
Demographic trap
When a country is stuck in a vicious circle of rapid growth population
biofuel ; Advantage of climate change point.
Climate change point view : biofuels produced by agriculture crops, carbon dyoxyde can be recaptured when you grow them again by photosynthese. Use of biofuel allow you recapture when you burn them.
In the case of fossil fuels, when you burn them, you release carbon dioxyde from the atmosphere
The carbon dioxyde released by burning biofuels can be recaptured when you grow them again through photosynthesis.

old pipolllle
Net benefit
if a project creates more resources than it uses it
e.g. 10L gas for 100 fishes
4 natural limits onn the growth of a city (MUMFORD)
- nutritional limit of adequate food and wwater supply
- Military limits of protecting walls and fortification
- Traffic limits set by slow moving agents
- power limits
rebound effect
Appliances a lot more efficient, but there is a lot more appliances
- Direct/Indirect effect : the energy being saved is being used somewhere else
Financial incentives for transport
- Gas taxes
- automobile taxes
- driver license cost
- parking cost

number of year a new-born child is expected to live
Nigeria/central africa/sierra leonne ; 52
Japan : 82
