Last fall in the section I teach of introductory microeconomics, I asked a student a simple question about the demand and supply of gutters. Nora had a blank expression, one that said, “I haven’t a clue of what you’re talking about.” If Nora had been struggling to understand economics, I wouldn’t have thought a thing about it. But Nora is a star, one who shines brightest when asked really tough questions.
Then it occurred to me. Nora didn’t know what the word “gutter” meant. It is easy to forget that Nora is Bulgarian -- her English is that good. I asked her whether she knew what the word meant, and looking embarrassed, she replied that she didn’t. How do you explain what gutters are without using the word gutter? It’s not easy, at least not for me. So, I broke into pantomime, with my fingers simulating raindrops heading for a cliff where they were caught by an invisible gutter.
Suddenly, her face lit up, and she quickly answered my original question. But it had taken her longer than I would have expected, even adjusting for my pantomiming skills. Still puzzled, I asked her, “How do you say ‘gutter’ in Bulgarian?” She said she didn’t know. Amazed, I said, “You’re pulling my leg, right?” She wasn’t.
Are there gutters in Bulgaria? I don’t know; I’ve never been there. Everywhere I’ve lived, gutters are ubiquitous. Are they common elsewhere, or are they just an American thing?
One student disliked my treatment of Nora, saying on her evaluation of the class:
"Something that bothered not only me but other students (and I know this from talking to my classmates) was the way Professor Harrington picked on the international students. We had about five international students in the class, and one day Professor Harrington did a problem about gutters. The student he asked to answer the question was Bulgarian and did not know what the word ”gutter” meant, and Professor Harrington made a big deal out of this. He asked her how you would say “gutter” in Bulgarian."
She says, “He continued to [quiz international students about their understanding of English] in other classes, singling out the international students and making them look inferior to the rest of the class.”
If the student had listened to the quality of her international classmates’ answers to my questions, she would have realized that they were academically superior to the vast majority of their classmates. Indeed, their median grade was 4.0; they all spoke English fluently; and, their essays had fewer grammatical errors than most of their classmates. It seems implausible to me that any rational observer would infer that they were inferior based on my questions about their knowledge of a few English words.
But even Nora looked embarrassed when she “confessed” that she didn’t know what gutters were. She had no reason to be embarrassed, yet she was. Why?
Perhaps, it has to do with the power of gut feelings, which allow people to quickly categorize experiences without having to think too deeply about them. Following them can even save your life in situations where you need to make quick decisions, implying that gut feelings are probably hard-wired into us via evolution. Hence, gut feelings probably can’t easily be turned off, implying that Nora could have been embarrassed by the gutters episode regardless of whether it was justified. And this is a shame -- because good class interactions should be full of professors and students going in any number of directions, some of them uncomfortable, without worrying about appearances or comfort levels (or whether some comment is going to make you a poster child for the Academic Bill of Rights).
I was in a gray area with Nora, one that I did not perceive as being gray until I thought about the comments of this student. I feel badly that I might have embarrassed Nora -- it was certainly not my intention. Nevertheless, asking Nora whether she knew the word for gutter in Bulgarian was the highlight of the course for me. My intuition screamed at me to ask it and her answer rewarded the impulse -- not because I was happy to discover that she didn’t know the word, but because it made me think more deeply about the way in which languages compete with one another for survival. Indeed, many languages face extinction because they are cluttered with words that people no longer find useful. For example, some languages have dozens and dozens of different words for ice, which may not be a selling point in the coming age of global warming.
Nobel laureate Robert Solow argues that the most difficult thing to teach students is how to be creative in economics, followed closely by critical judgment. It is much easier to teach tools, such as demand and supply, than how to use them creatively, or critically. The first step in using economics creatively is to ask interesting questions, ones that naturally arise during genuine conversations sparked by observing differences like those concerning the acquisition of language. While these conversations are crucial in teaching students to be creative, they are also likely to tumble into gray areas and sometimes produce dry holes, two things that make some students uncomfortable.
Another way to be creative in economics is to apply economic reasoning to topics commonly thought to lie outside the realm of economics. Hence, I want my students to learn that there are no boundaries to the usefulness of economic reasoning. I mean NO boundaries, absolutely none. Boundaries smother creativity because they encourage students to turn off their economic reasoning skills whenever they cross them.
Last semester, I described how a San Diego abortion cartel in the late 1940s charged women different prices depending on the quality of their clothing and the characteristics of the person accompanying them, a practice that economists call price discrimination. For example, a young woman who was brought to the clinic by an unrelated, well-dressed Sacramento businessman was charged $2,600 for an abortion. If the woman had come alone, she would have paid something closer to $200. Four students have come to my office or e-mailed me with concerns over the use of examples like this one. For example, one student argued that abortion is too morally charged to be used as fodder for examples, especially ones that are so narrowly drawn.
Crossing the border into conversations about race is especially dangerous, because the border is patrolled by guards searching for insensitive comments. It takes courage and tolerance on the part of both students and professors to have genuine conversations about race. However, no topic is more important to discuss in economics courses given the glaring disparities in economic outcomes between African-Americans and whites. For another course I teach, students are required to read an article about the controversy that erupted when members of one middle-class community proposed naming a “nice street” after Martin Luther King Jr. The proponents wanted to weaken the correlation of his name with poverty and crime, while the opponents feared that naming a street after him would cause their neighborhood to decay. I admire the proposal yet empathize with the opponents. Since streets bearing his name are more commonly found in poor neighborhoods, (even unprejudiced) people might rationally "steer clear" of the area if they name a street after Martin Luther King Jr., a phenomenon economists call statistical discrimination.
Teaching students to use economics creatively requires having conversations that are not smothered by fears of saying something wrong or of stepping over some boundary beyond which economic reasoning is prohibited. But genuine conversations require that students have done enough of the reading to participate with intelligence -- and checking on that may also make students uncomfortable.
A student last fall accused me in his or her course evaluation of picking on students, saying that “if it was obvious a student was unprepared or had not done the assigned reading [Professor Harrington] would call them out on it.” It’s true. I admit it. Failing to read the assigned articles imposes spillover costs on other students that can be corrected by imposing penalties on unprepared students. For example, one student could not answer straightforward questions about the readings in two consecutive classes, prompting me to ask him whether he had ever heard of the expression, “three strikes and you’re out.” At the beginning of the third class, he joined the conversation, easily answering my initial questions and making a few comments of his own.
