In the year 2010, suppose the Gini ratio for Canada was 0.30 and the Gini ratio for the US was 0.50. In the year 2015, suppose the Gini ratio for Canada rises to 0.35. Which of the following statements is true?Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer.aCanada has greater inequality than the US. bCanada has greater inequality in 2015 than it did in 2010.cThe US has greater equality than Canada.dBetween 2010 and 2015 Canada’s Lorenz curve has become straighter (closer to the diagonal).

2. In a given country, there are 5 people that earn $1 per year and 5 people that earn $ 3 per year.(a) Draw the Lorenz curve for this country.(b) On the diagram indicate (using the areas) how you would calculate the Gini coefficient

Consider an economy with a particular distribution of income. Over the next 10 years, the income of ALL households increases by exactly $20,000. How will the Gini coefficient change over those 10 years?  The Gini coefficient will decrease.   The Gini coefficient will stay the same as all households received the same increase in income.   The Gini coefficient will become more negative.   It is impossible to determine how the Gini coefficient will change as it will depend on the original income distribution.   The Gini coefficient will increase.
