school choice is good

In a new paper in the Review of Economic Studies, Victor Lavy (Hebrew U) considers what happens when students can attend any public school they want. That is, he looks at the impact that free public school choice has on graduation rates, student performance, and other outcomes. From the abstract:

Across identification methods and comparison groups, the results consistently suggest that choice significantly reduces the drop-out rate and increases the cognitive achievements of high-school students. It also improves behavioural outcomes such as teacher–student relationships and students' social acclimation and satisfaction at school, and reduces the level of violence and classroom disruption.

Across the board, school choice looks like a winning policy. Download the paper here.

voting patterns drive PAC contributions

Do PACs give political contributions in an effort to "bribe" or otherwise convince politicians into voting in their favor? Or, do PACs give political contributions to the politicians that have underlying preferences consistent with the PACs positions (i.e., those politicians who would vote in favor of the PAC regardless of their contributions)?

In a recent NBER working paper, Dalton Conley and Brian McCabe (NYU) present some evidence that the later story might be correct, at least in some situations. First, they show that politicians are more likely to vote liberally on women's issues when they daughters. (This has been shown before.) Second, they show that this exogenous change in voting behavior has a significant impact on PAC contributions, suggesting that contributions follow from voting choices, not the other way around.

daughters make you more conservative

In 2008, I wrote about a paper by Ebonya Washington which showed that legislators with daughters were more liberal as reflected in their voting records. A new NBER working paper by Dalton Conley and Emily Rauscher (NYU) suggest that maybe "elite politicians" are affected differently than the "general citizenry."

They show that "female offspring induce more conservative political identification."

Controlling for gender, religion, age, education, and marital status, the proportion of girls [children] significantly increases Republican Party identification in the United States.

Why would this be? The authors suggest that "daughters may elicit grandparental preferences for a world in which male sexuality is constrained and parental investment in offspring is greater."

physical attractiveness and performance

Previous papers have shown that physical attractiveness has a positive impact on student performance. However, the past studies tend to not control for other characteristics that may be highly correlated with attractiveness, including personality and grooming. In a recent paper in Labour Economics, Michael French, Philip Robins, Jenny Homer, and Lauren Tapsell (all at U Miami) conclude:

Including personality and grooming, the effect of physical attractiveness turns negative for both groups, but is only statistically significant for males. For male and female students, being very well groomed is associated with a statistically significant GPA premium. While grooming has the largest effect on GPA for male students, having a very attractive personality is most important for female students.

did no child left behind work?

Thomas Dee (Swarthmore) and Brian Jacob (Harvard) empirically consider the impact of No Child Left Behind legislation in the U.S. From the abstract:

Our results indicate that NCLB generated statistically significant increases in the average math performance of 4th graders as well as improvements at the lower and top percentiles. There is also evidence of improvements in 8th grade math achievement, particularly among traditionally low-achieving groups and at the lower percentiles. However, we find no evidence that NCLB increased reading achievement in either 4th or 8th grade.

From the introduction:

The lack of any effect in reading, and the fact that NCLB appears to have generated only modestly larger impacts among disadvantaged subgroups in math (and thus only made minimal headway in closing achievement gaps), suggests that, to date, the impact of NCLB has fallen short of its ambitious “moon-shot rhetoric”

high school sports and teen pregnancy

Females who participate in sports are less likely to get pregnant than ones who do not. This has largely been used to insinuate that by participating in sports, a girl decreases her chances of getting pregnant. In a recent working paper, Joseph Price (BYU), Daniel Simon (Cornell), and Betsey Stevenson (Penn) find the flaw in this logic.

The authors point out that girls who decide to participate in sports may be significantly different from the typical girl who does not participate. They are likely more confidence, for example. We observe that sports participants are less likely to get pregnant; this is different from saying that a girl who plays sports is less likely to get pregnant than the same girl if she was not on a sports team.

It turns out that sports participation actually increases the pregnancy rate among girls. To show this, the study looks at the effect of Title XI, and the introduction of additional female sports participation, on pregnancy rates. From the paper's abstract:

We find that a 10 percentage point increase in the fraction of girls playing sports in a state increases the teen birth rate by 0.3 percentage points (about a 10% increase). However, there are racial differences in the effect of sports participation. The increase in the teen birth rate is most pronounced for white young women with some suggestive evidence that sports decreases teen birth rates among black young women.

longer school days and student performance

In the current issue of Economics of Education Review, Cristián Bellei (U Chile) considers whether lengthening the school day increases student achievement. Looking at a change in the length of a school day in Chile, the paper shows that more classroom time increases achievement in mathematics and language. This impact is larger for public school, rural, and high-achieving students.

parents, child self confidence, and child performance

In a recent paper, Rajeev Darolia (George Washington) and Bruce Wydick (U San Francisco) test how parents can affect the academic effort and performance of a child through "signals," such as praise or financial rewards. From the abstract:

Our results show that some complementary actions before college, such as parental praise, foster academic achievement above what natural ability would predict. Conversely, we find that some substitutionary actions before college, e.g. providing cars as gifts, are associated with lower effort in college and underachievement.

I was particularly amused by the car-buying result. The article is forthcoming in Economica. Link to it here, or here.

demand for sons and daughters

Gordon Dahl (UCSD) and Enrico Moretti (Berkeley) consider whether there is a larger demand for sons than for daughters in the United States. It may be impossible to design a single empirical test that will answer this question, and the authors do not attempt to do so. Instead, the authors conduct a number of separate tests that, taken together, provide significant evidence that parents do prefer boys. From their abstract:

In this paper, we show that child gender affects the marital status, family structure, and fertility of a significant number of American families. Overall, a first-born daughter is significantly less likely to be living with her father compared to a first-born son. Three factors are important in explaining this gap. First, women with first-born daughters are less likely to marry. Strikingly, we also find evidence that the gender of a child in utero affects shotgun marriages. Among women who have taken an ultrasound test during pregnancy, mothers who have a girl are less likely to be married at delivery than those who have a boy. Second, parents who have first-born girls are significantly more likely to be divorced. Third, after a divorce, fathers are much more likely to obtain custody of sons compared to daughters. These three factors have serious negative income and educational consequences for affected children...We show that the number of children is significantly higher in families with a first-born girl.

do fast food ads result in fat kids?

In a new paper out in The Journal of Law and Economics, Shin-Yi Chou (Lehigh), Inas Rashad (Georgia State), and Michael Grossman (CUNY) study the effects that fast-food advertising on TV has on overweight children. They estimate that banning advertisements would decrease the number of overweight children by 14 to 18 percent. A ban might not be optimal, however, since it may also reduce the amount of information available to consumers. (For example, being informed that it is Monopoly time at McDonalds could arguably make you better off.)

The authors go on to show that eliminating the "tax deductability of would produce smaller declines of between 5 and 7 percent in these outcomes but would impose lower costs on children and adults who consume fast food in moderation because positive information about restaurants that supply this type of food would not be completely banned from television."

pro-girl teacher biases

Victor Lavy (Hebrew U) looks for gender biases held by high school teachers in Israel. His results suggest that girls benefit from teacher biases, which is largely contrary to popular beliefs that teacher biases may harm girls. The abstract:

Schools and teachers are often said to be a source of stereotypes that harm girls. This paper tests for the existence of gender stereotyping and discrimination by public high-school teachers in Israel. It uses a natural experiment based on blind and non-blind scores that students receive on matriculation exams in their senior year. Using data on test results in several subjects in the humanities and sciences, I found, contrary to expectations, that male students face discrimination in each subject. These biases widen the female–male achievement difference because girls outperform boys in all subjects, except English, and at all levels of the curriculum. The bias is evident in all segments of the ability and performance distribution and is robust to various individual controls. Several explanations based on differential behavior between boys and girls are not supported empirically. However, the size of the difference is very sensitive to teachers' characteristics, suggesting that the bias against male students is the result of teachers', and not students', behavior.

information availability and school choice program participation

It has been shown that low-income families put less weight on academic quality when choosing schools. They are less likely to take part in school-choice programs, in which they can apply for their children to attend a different school than originally assigned based on geography. This implies that school-choice programs may not have as large of a benefit for low-income families than may be possible, if they were more likely to take advantage of such programs.

In a recent QJE article, Justine S. Hastings (Yale) and Jeffrey M. Weinstein (Syracuse) consider show that providing low-income families with data on school performance increases the probability that they participate in a school-choice program. They find "that school choice will most effectively increase academic achievement for disadvantaged students when parents have easy access to test score information and good options from which to choose."

holding kids back and graduation rates

Brian A. Jacob (U Mich) and Lars Lefgren (BYU) study the impact that holding grade school students back has on graduation rates. Their abstract:

Low-achieving students in many school districts are retained in a grade in order to allow them to gain the academic or social skills that teachers believe are necessary to succeed academically. In this paper, we use plausibly exogenous variation in retention generated by a test-based promotion policy to assess the causal impact of grade retention on high school completion. We find that retention among younger students does not affect the likelihood of high school completion, but that retaining low-achieving eighth grade students in elementary school substantially increases the probability that these students will drop out of high school.

donations to universities to help one's child get accepted

Jonathan Meer (Stanford) and Harvey S. Rosen (Princeton) study alumni donations to a university, and show that alumni are more likely to give money as their children approach college age. Their abstract:

We study alumni contributions to an anonymous research university. If alumni believe donations will increase the likelihood of their child’s admission, and if this belief helps motivate their giving, then the pattern of giving should vary systematically with the ages of their children, whether the children ultimately apply to the university, and the admissions outcome. We call this pattern the child cycle of alumni giving. The evidence is consistent with the child-cycle pattern. Thus, while altruism drives some giving, the hope for a reciprocal benefit also plays a role. We compute rough estimates of the proportion of giving due to selfish motives.

So, their story only requires that alumni believe that contributions increase the probability of their children being accepted. Now, I would like to see someone determine whether this belief has support in the data.

computers aided versus traditional instruction

Lisa Barrow (Chicago Fed), Lisa Markman (Princeton), and Cecilia Elena Rouse (Princeton) study the use of computer instruction in teaching mathematics. Their abstract:

We present results from a randomized study of a well-defined use of computers in schools: a popular instructional computer program for pre-algebra and algebra. We primarily assess the program using a test designed to target pre-algebra and algebra skills. Students randomly assigned to computer-aided instruction score significantly higher on a pre-algebra and algebra test than students randomly assigned to traditional instruction. We hypothesize that this effectiveness arises from increased individualized instruction as the effects appear larger for students in larger classes and in classes with high student absentee rates.

foster care and adult crime

Joseph Doyle (MIT) studies the impact of foster care on child outcomes -- namely whether they commit crimes as adults. To do so, Doyle first shows that whether a child ends up in foster care often depends on the identity of his or her case worker. Some case workers are more likely than others to place children in foster care. Because case workers are randomly assigned to cases, whether a child ends up in foster care (for marginal cases) is random. This randomness can be used to measure the effects of foster care. Do children assigned to a foster-care prone case worker tend to have different outcomes than children assigned to a case worker that is less likely to place them in foster care?

From the abstract:

Children on the margin of placement are found to be two to three times more likely to enter the criminal justice system as adults if they were placed in foster care. One innovation describes the types of children on the margin of placement, a group that is more likely to include African Americans, girls, and young adolescents.

impact of universal child care

In a recent Journal of Political Economy paper, Michael Baker (Toronto), Jonathan Gruber (MIT), and Kevin Milligan (British Columbia) study the effects of a universal child care program in Quebec. Unsurprisingly, they find that the program significantly increases maternal labor supply--more moms return to work and/or work more after the birth of a child. What's surprising is that the program appears to make children worse off on a variety of dimensions.

...the evidence suggests that children are worse off by measures ranging from aggression to motor and social skills to illness. We also uncover evidence that the new child care program led to more hostile, less consistent parenting, worse parental health, and lower-quality parental relationships.

Why would this be? Does this mean that childcare in general could be causing these affects? Not necessarily. First, they cannot rule out that these negative aspects result from a short-term adjustment process, as families adjust to using childcare. Second, I speculate that universal childcare likely changes the composition of children at daycare centers, which may have similar results as changing the composition of inmates at a juvenile detention center (see the earlier post).

women's suffrage and child health

Are women more concerned than men about the wellbeing of children? If that is true--or if politicians perceive it to be true--then increasing female participation in politics could lead to more policies that benefit children. Grant Miller (Stanford) tests this hypothesis in a new paper in the Quarterly Journal of Economics. He finds evidence suggesting that giving women the right to vote led to higher child wellbeing. From the paper abstract:

...Suffrage rights for American women helped children to benefit from the scientific breakthroughs of the bacteriological revolution. ... Suffrage laws were followed by immediate shifts in legislative behavior and large, sudden increases in local public health spending. This growth in public health spending fueled large-scale door-to-door hygiene campaigns, and child mortality declined by 8–15% (or 20,000 annual child deaths nationwide)...

having daughters might make you more liberal

A recent paper by Ebonya Washington (Yale) in the American Economic Review considers whether congressmen & women who parent daughters tend to vote differently than otherwise similar representatives that father sons instead. Unlike many papers in economics, her abstract is easy to read:

Parenting daughters, sociologists have shown, increases feminist sympathies. I test the hypothesis that children, much like neighbors or peers, can influence parental behavior. I demonstrate that conditional on total number of children, each daughter increases a congressperson's propensity to vote liberally, particularly on reproductive rights issues. The results identify an important (and previously omitted) explanatory variable in the literature on congressional decision making. Additionally the paper highlights the relevance of child-to-parent behavioral influence.
