1. Which will be larger for a country: PG or APG? Please explain. (8 points)

2. Country A and Country B have the same population of 200 million. Use the figures in the table below to calculate the head-count ratio and average poverty gap in each country. Finally, carefully interpret the results. (8 points)

Income Distribution below poverty line ($1 per day) 25 cents per day     50 cents per day                75 cents per day

Country A (millions of people)        90     30    30

Country B (millions of people)        10     60    80

3. Can the Lorenz curve slope downward? Please explain. (8 points)        Econ homework代写

4. This table below reports the distribution of income in Canada and the United States.

Quintile            1st            2nd             3rd            4th            5th            

Canada            7.7               13.7            19.0          24.8          34.8

U.S.                  4.5               10.7            16.6          24.1          44.1

Draw the Lorenz curves for the two countries in the same graph. Without actually calculating the Gini coefficient, use the information from the Lorenz curves and explain which country has the lower income inequality measure. (8 points)

5. From the data in 4, compute the Gini coefficient for both countries. Does this agree with your answer to the previous question? (8 points)

6. If all income quintiles in a country experience the same percentage increase in income, what happens to the Lorenz curve? (8 points)

7. For the sake of this question, let’s assume a country with a zero return to education and education is the only factor that affects income, which is $30,000 per person. What would the Lorenz curve look like? (8 points)

8. Now, let’s modify the last question and say that the return to education is 20% and that those with no income earn $10,000 a year. There are five equal sized groups in the economy and the first has no education, the second has 1 year,  the third has 2 years, and so on. Draw the Lorenz curve. (8 points)

9. How do the Lorenz curves from 7 and 8 differ? What concept does this change illustrate? (6 points)

10. Please read the article “To Beat Back Poverty, Pay the Poor” and answer this and the next two questions. First, how do these “conditional cash transfer” programs affect the average poverty gap in the countries that use them? (5 points)

11. Next, what happened to the Lorenz curve and Gini coefficient in Brazil as a result of the introduction of the Bolsa Familia? Be sure to fully explain your answer. (5 points)

12. Finally, what is the likely impact of Mexico’s Oportunidades program on intergenerational mobility? Please explain. (5 points)

13. Please read the article “Hope Springs a Trap” and answer this and the next two questions. First, from the first four paragraphs in the article, name two specific clues that led Duflo and Bardhan to believe that it is indeed the absence of optimism that played a large role in keeping people trapped in poverty. (5 points)

14. What are two examples that illustrate that the poor have misconceptions (ideas that are contrary to economic findings in the area) about what they can do to escape the poverty trap? (5 points)

15. What is the nature of the law in India that has led to a striking degree of convergence between goals for sons and daughters? (5 points)

Hope Springs a Trap – The Economist

An absence of optimism plays a large role in keeping people trapped in poverty           Econ homework代写

THE idea that an infusion of hope can make a big difference to the lives of wretchedly poor people sounds like something dreamed up by a well-meaning activist or a tub-thumping politician. Yet this was the central thrust of a lecture at Harvard University on May 3rd by Esther Duflo, an economist at the Massachusetts Institute of Technology known for her data-driven analysis of poverty.

Ms Duflo argued that the effects of some anti-poverty programmes go beyond the direct impact of the resources they provide. These programmes also make it possible for the very poor to hope for more than mere survival.

She and her colleagues evaluated a programme in the Indian state of West Bengal, where Bandhan, an Indian microfinance institution, worked with people who lived in extreme penury. They were reckoned to be unable to handle the demands of repaying a loan. Instead, Bandhan gave each of them a small productive asset—a cow, a couple of goats or some chickens.

It also provided a small stipend to reduce the temptation to eat or sell the asset immediately, as well as weekly training sessions to teach them how to tend to animals and manage their households. Bandhan hoped that there would be a small increase in income from selling the products of the farm animals provided, and that people would become more adept at managing their own finances.

The results were far more dramatic.    Econ homework代写

Well after the financial help and hand-holding had stopped, the families of those who had been randomly chosen for the Bandhan programme were eating 15% more, earning 20% more each month and skipping fewer meals than people in a comparison group. They were also saving a lot. The effects were so large and persistent that they could not be attributed to the direct effects of the grants: people could not have sold enough milk, eggs or meat to explain the income gains. Nor were they simply selling the assets (although some did).

So what could explain these outcomes?

One clue came from the fact that recipients worked 28% more hours, mostly on activities not directly related to the assets they were given. Ms Duflo and her co-authors also found that the beneficiaries’ mental health improved dramatically: the programme had cut the rate of depression sharply.

She argues that it provided these extremely poor people with the mental space to think about more than just scraping by. As well as finding more work in existing activities, like agricultural labour, they also started exploring new lines of work. Ms Duflo reckons that an absence of hope had helped keep these people in penury; Bandhan injected a dose of optimism.

Ms Duflo is building on an old idea. Development economists have long surmised that some very poor people may remain trapped in poverty because even the largest investments they are able to make, whether eating a few more calories or working a bit harder on their minuscule businesses, are too small to make a big difference. So getting out of poverty seems to require a quantum leap—vastly more food, a modern machine, or an employee to mind the shop.

As a result, they often forgo even the small incremental investments of which they are capable: a bit more fertiliser, some more schooling or a small amount of saving.

This hopelessness manifests itself in many ways.   Econ homework代写

One is a sort of pathological conservatism, where people forgo even feasible things with potentially large benefits for fear of losing the little they already possess. For example, poor people stay in drought-hit villages when the city is just a bus ride away. An experiment in rural Bangladesh provided men with the bus fare to Dhaka at the beginning of the lean season, the period between planting and the next harvest when there is little to do except sit around.

The offer of the bus fare, an amount which most of the men could have saved up to pay for themselves, led to a 22-percentage-point increase in the probability of migration. The money migrants sent back led their families’ consumption to soar. Having experienced the $100 increase in seasonal consumption per head that the $8 bus fare made possible, half of those offered the bus fare migrated again the next year, this time without the inducement.

People sometimes think they are in a poverty trap when they are not.      Econ homework代写

Surveys in many countries show that poor parents often believe that a few years of schooling have almost no benefit; education is valuable only if you finish secondary school. So if they cannot ensure that their children can complete school, they tend to keep them out of the classroom altogether. And if they can pay for only one child to complete school, they often do so by avoiding any education for the children they think are less clever.

Yet economists have found that each year of schooling adds a roughly similar amount to a person’s earning power: the more education, the better. Moreover, parents are very likely to misjudge their children’s skills. By putting all their investment in the child who they believe to be the brightest, they ensure that their other children never find out what they are good at. Assumed to have little potential, these children live down to their parents’ expectations.

The fuel of self-belief       Econ homework代写

Surprising things can often act as a spur to hope. A law in India set aside for women the elected post of head of the village council in a third of villages. Following up several years later, Ms Duflo found a clear effect on the education of girls. Previously parents and children had far more modest education and career goals for girls than for boys.

Girls were expected to get much less schooling, stay at home and do the bidding of their in-laws. But a few years of exposure to a female village head had led to a striking degree of convergence between goals for sons and daughters. Their very existence seems to have expanded the girls’ sense of the possible beyond a life of domestic drudgery. An unexpected consequence, perhaps, but a profoundly hopeful one.


The programme with the ultra-poor in West Bengal evaluated by Ms Duflo was implemented by Bandhan, not BRAC, as we mistakenly wrote in the original version of this article. BRAC devised the original programme on which Bandhan’s was based.
