Explanation of Solution

Lorenz curve:

is defined as a curve that measures the degree of inequality of income distribution of an economy.

When the income is equally distributed, the Lorenz curve will be a straight 45 degree line.

In case of a normal economy, the Lorenz curve will lie beneath it, presenting the reality of wealth distribution.

As per the definition, this curve cannot be bowed upward as the bottom 10% of incomes can't earn more than the top 90% of incomes.

Economics Concept Introduction

Lorenz curve:

is defined as a curve that measures the degree of inequality of income distribution of an economy.

In other words, it is defined as a graph on which the cumulative percentage of total national income is plotted against the corresponding population (cumulative percentage of the corresponding population)

The degrees to which this curve sags below the straight line represents the degree of inequality in the distribution of income.

Difference-in-Difference In the beginning of 2001, North Dakota legalized fireworks. Suppose you are interested in studying the effect of the legalizing of fireworks on the number of house fires in North Dakota. Unlike North Dakota, South Dakota did not legalize fireworks and continued to ban them. You decide to use a Difference-in-difference (DID) Model. The numbers of house fires in each state at the end of 2000 and 2001 are as follows: Number of house fires in Number of house fires in Year North Dakota 2000 2001 35 50 South Dakota 54 64 a. What is the change in the outcome for the treatment group between 2000 and 2001? Show your working for full credit. (10 points) b. Can we interpret the change in the outcome for the treatment group between 2000 and 2001 as the causal effect of legalizing fireworks on number of house fires? Explain your answer. (10 points)
C. Regression Discontinuity Birth weight is used as a common sign for a newborn's health. In the United States, if a baby has a birthweight below 1500 grams, the newborn is classified as having “very low birth weight". Suppose you want to study the effect of having very low birth weight on the number of hospital visits made before the baby's first birthday. You decide to use Regression Discontinuity to answer this question. The graph below shows the RD model: Number of hospital visits made before baby's first birthday 5 1400 1450 1500 1550 1600 Birthweight (in grams) a. What is the running variable? (5 points) b. What is the cutoff? (5 points) T What is the discontinuity in the graph and how do you interpret it? (10 points)
