Answers.
a)Income elasticity of demand measures the responsiveness of demand for a particular good to changes in consumer income. The higher the income elasticity of demand for a particular good, the more demand for that good is tied to fluctuations in consumer's income.
b)The two countries with highest per capita demand could be China and Russia.
c)The potential future effects of global climate change include more demand for air conditioners, longer periods of drought in some regions and an increase in the number, duration and intensity of tropical storms.
d) The expected results is that there will be a considerable increase in global warming.
