This document discusses global warming and its effects on polar bears, penguins, and the North and South Poles. It also mentions the Kyoto Protocol and climate change. The rest of the document focuses on diesel fuel in Bangladesh, including the price of diesel over the years, its top uses by sector, its inelastic demand, factors that determine its elasticity, what cross elasticity is, and how diesel's cross elasticity would be affected by changes in the price of substitutes like CNG. The document was prepared by three students and thanked their lecturer for English 102.

11. Elasticity of demand for diesel inElasticity of demand for diesel in
BangladeshBangladesh
According to the all those sectors Diesel are more inelastic
good in Bangladesh.
Bangladesh is a agricultural based country and our
Agricultural dependent on diesel.
Our railway sector is dependent on Diesel.
Some of the transportation is also runs on Diesel.
Power engines like generator also runs on diesel.

12. Price
A E
B F
Demand
C D Quantity
An inelastic demand shows that a big change in price results to a
smaller change in quantity demanded. So for a high increase in
price quantity demanded will fall in a small range. This is cause
there are no alternative goods for diesel, industries will need
diesel to run their machines.

13. Factors that determines diesel’s
Elasticity
Necessity or a luxury
Availability of a substitute
Time (in a short or a long run)
Percentage of the total budget

14. What is Cross Elasticity
Cross elasticity of demand or cross-price elasticity of
demand measures the responsiveness of the demand
for a good to a change in the price of another good.

15. Formula for Cross Elasticity
For substitute if the price of A increases then the
demand for B increases.(+ve)
For complement if the price of A decreases then the
demand for B increases.(-ve)

16. Comment on Diesel’s Cross
Elasticity
If the price of CNG goes up which is an substitute for
diesel then the demand for diesel will also increase.
There are no complements for diesel because the cars
that runs on diesel can not run on fuel.
