What is Economics for? What should economists spend their time doing? In the prologue to his “Economics: A Very Short Introduction,” Partha Dasgupta tells us about the world of Becky, 10 years old, who
…lives with her parents and an older brother Sam in a suburban town in America’s Midwest. Becky’s father works in a firm specializing in property law. Depending on the firm’s profits, his annual income varies somewhat, but is rarely below $145,000. Becky’s parents met at college. For a few years her mother worked in publishing, but when Sam was born she decided to concentrate on raising a family. Now that both Becky and Sam attend school, she does voluntary work in local education. The family live in a two-storey house. It has four bedrooms, two bathrooms upstairs and a toilet downstairs, a large drawing-cum-dining room, a modern kitchen, and a family room in the basement. There is a plot of land at the rear – the backyard – which the family use for leisure activities.
Although their property is partially mortgaged, Becky’s parents own stocks and bonds and have a saving account in the local branch of a national bank. Becky’s father and his firm jointly contribute to his retirement pension. He also makes monthly payments into a scheme with the bank that will cover college education for Becky and Sam. The family’s assets and their lives are insured. Becky’s parents often remark that, because federal taxes are high, they have to be careful with money; and they are. Nevertheless, they own two cars; the children attend camp each summer; and the family take a vacation together once camp is over. Becky’s parents also remark that her generation will be much more prosperous than theirs. Becky wants to save the environment and insists on biking to school. Her ambition is to become a doctor.
Then there is Desta, 10 year old from Ethopia:
Desta, who is about 10 years old, lives with her parents and five siblings in a village in subtropical, southwest Ethiopia. The family live in a two-room, grass-roofed mud hut. Desta’s father grows maize and teff (a staple cereal unique to Ethiopia) on half a hectare of land that the government has awarded him. Desta’s older brother helps him to farm the land and care for the household’s livestock, which consist of a cow, a goat, and a few chickens. The small quantity of stuff produced is sold so as to raise cash income, but the maize is in large measure consumed by the household as a staple.
Desta’s mother works a small plot next to their cottage, growing cabbage, onions, and enset (a year-round root crop that also serves as a staple). In order to supplement their household income, she brews a local drink made from maize. As she is also responsible for cooking, cleaning, and minding the infants, her work day usually lasts 14 hours. Despite the long hours, it wouldn’t be possible for her to complete the tasks on her own. (As the ingredients are all raw, cooking alone takes 5 hours or more.) So Desta and her older sister help their mother with household chores and mind their younger siblings. Although a younger brother attends the local school, neither Desta nor her older sister has ever been enrolled there. Her parents can neither read nor write, but they are numerate.
Desta’s home has no electricity or running water. Around where they live, sources of water, land for grazing cattle, and the woodlands are communal property. They are shared by people in Desta’s village; but the villagers don’t allow outsiders to make use of them. Each day Desta’s mother and the girls fetch water, collect fuelwood, and pick berries and herbs from the local commons. Desta’s mother frequently complains that the time and effort needed to collect their daily needs has increased over the years.
There is no financial institution nearby to offer either credit or insurance. As funerals are expensive occasions, Desta’s father long ago joined a community insurance scheme (iddir) to which he contributes monthly. When Desta’s father purchased the cow they now own, he used the entire cash he had accumulated and stored at home, but had to supplement that with funds borrowed from kinfolk, with a promise to repay the debt when he had the ability to do so. In turn, when they are in need, his kinfolk come to him for a loan, which he supplies if he is able to. Desta’s father says that such patterns of reciprocity he and those close to him practise are part of their culture. He says also that his sons are his main assets, as they are the ones who will look after him and Desta’s mother in their old age.
Where does Economics fit in?
Economics in great measure tries to uncover the processes that influence how people’s lives come to be what they are. The discipline also tries to identify ways to influence those very processes so as to improve the prospects of those who are hugely constrained in what they can be and do. The former activity involves finding explanations, while the latter tries to identify policy prescriptions. Economists also make forecasts of what the conditions of economic life are going to be; but if the predictions are to be taken seriously, they have to be built on an understanding of the processes that shape people’s lives; which is why the attempt to explain takes precedence over forecasting.
Understanding their [Becky's and Desta's] lives involves a lot more; it requires analysis, which usually calls for further description. To conduct an analysis, we need first of all to identify the material prospects the girls’ households face – now and in the future, under uncertain contingencies. Second, we need to uncover the character of their choices and the pathways by which the choices made by millions of households like Becky’s and Desta’s go to produce the prospects they all face. Third, and relatedly, we need to uncover the pathways by which the families came to inherit their current circumstances.
These amount to a tall, even forbidding, order. Moreover, there is a thought that can haunt us: since everything probably affects everything else, how can we ever make sense of the social world? If we are weighed down by that worry, though, we won’t ever make progress. Every discipline that I am familiar with draws caricatures of the world in order to make sense of it. The modern economist does this by building models, which are deliberately stripped down representations of the phenomena out there. When I say ’stripped down’, I really mean stripped down.
And what can we take as given about these two girls before building our models?
That the lives people are able to construct differ enormously across the globe is a commonplace. In our age of travel, it is even a common sight. That Becky and Desta face widely different futures is also something we have come to expect, perhaps also to accept. Nevertheless, it may not be out of turn to imagine that the girls are intrinsically very similar. They both enjoy playing, eating, and gossiping; they are close to their families; they turn to their mothers when in distress; they like pretty things to wear; and they both have the capacity to be disappointed, get annoyed, be happy. Their parents are also alike. They are knowledgeable about the ways of their worlds. They also care about their families, finding ingenious ways to meet the recurring problem of producing income and allocating resources among family members – over time and allowing for unexpected contingencies.
