Anyone languishing in the shadow of a more financially successful sibling can take hope from a new study from the National Bureau of Economic Research, which concludes that siblings' incomes tend to converge over the course of their lifetimes. This tendency is weaker among siblings on the lower rungs of the socioeconomic ladder. But it is stronger among black siblings overall—a counterintuitive finding, the authors write, that "begs for further research." The study suggests that even when factors relating to shared background—similarities in education and occupational prestige—are taken into account, roughly 60 percent of the phenomenon is unexplained, and may be genetically based. The researchers note, however, that they used the relatively simplistic "years of schooling" as a marker of education; it may be that shared educational status (as in a family whose children all attend private rather than public colleges) is responsible for some of the correlation.

Adoption Options

Taking in a child from abroad is often perceived as riskier than domestic adoption, because orphans in countries from which Westerners adopt often suffer from poor medical care, malnutrition, or abuse. But some of those fears may be put to rest by a study in the Journal of the American Medical Association. Two researchers from Leiden University, in the Netherlands, reviewed medical literature on the behavioral problems of adoptees in the United States, Canada, Western Europe, and elsewhere in the developed world from the 1950s to the present. They concluded that children adopted from other countries were less likely than domestic adoptees to experience behavioral problems or to be referred for mental-health treatment. They postulate that the explanation may lie in part with the adoptive parents: those willing to adopt a child from overseas may be more "highly motivated to raise children" than parents who adopt from within their own country. In addition, they theorize, obvious racial differences between parents and children, which are more likely to exist in families formed through international adoption, may prevent parents from trying to keep the fact of the adoption a secret from their child, "resulting in more communication and trust."

Lonely at the Top

Social scientists have long debated whether a cultural bias against "acting white" affects academic performance among minority youths. A recent paper provides new fodder. For white teenagers it finds a correlation between higher grades and popularity among other whites. Same-race popularity also rises along with grades for black and Hispanic teenagers, up to a point; but above a certain achievement level the trend reverses. For blacks popularity peaks at a GPA of 3.5 (B+) and then declines; a black student with a 4.0 average, or straight As, has about as many black friends as a black student with a 2.9 GPA. The threshold for Hispanics is much lower: popularity begins to decline at a GPA of 2.5 (C+), and a Hispanic student with a 4.0 average is less popular among other Hispanics than one with a 1.0. These losses are not offset by cross-racial friendships; if anything, the study notes, higher grades appear to cost blacks and Hispanics white friends as well. The stigma attached to "acting white" appears more pronounced in racially mixed environments; in largely black schools it all but disappears, as if the presence of white students is required for minorities to be perceived as—and ostracized for—"acting like" them.

"G" Is for "Greenbacks"

Would Hollywood make more money if it emphasized movies suitable for all ages over those containing sex and violence? This question was posed by the Dove Foundation, an organization that seeks to "promote the creation, production and distribution of wholesome family entertainment." The Dove study examined all movies released in U.S. theaters from 1989 to 2003. Those with a G rating made an average profit of nearly $80 million, compared with only $7 million for those with an R rating. Yet G-rated movies accounted for only four percent of all movies released during those years (123 of 2,982), while the 1,533 R-rated movies accounted for 52 percent. The Dove study doesn't mention that though R-rated films individually made a lot less money, collectively they won a lot more awards: of the fifteen Oscar winners for Best Picture during the years studied, eight were rated R, six were PG-13, and only one—Driving Miss Daisy (1989)—was sufficiently family-friendly for a PG.

The Poor Get Poorer

It's a paradoxical fact that being poor frequently results in having to spend more, not less, than other people on goods and services, whether health care (which is costly without comprehensive insurance) or groceries (which are generally overpriced in inner-city supermarkets). Recently the Brookings Institution, in Washington, D.C., studied low-income families in Philadelphia in an effort to quantify these additional costs. Such families, the researchers found, pay at least $500 more than other families in the city for the same type of car, both because they are less likely to comparison shop and because poor consumers, being likelier to default, are charged higher rates on auto and other loans. And the annual cost of insuring that car and its driver is, on average, $400 higher for families living in the city's poor neighborhoods, where accident and theft rates are high. The poor often do not have bank accounts and instead must rely on check-cashing establishments, which in Pennsylvania may legally charge up to three percent to cash payroll checks—a fee that amounts to $450 a year for a household earning $15,000. They are less likely to be able to buy furniture and appliances outright, and the markup on installment plans can be staggering: in Philadelphia it averages 90 percent over the purchase price. And the poor are likelier than other people to take out short-term loans, which in Pennsylvania may have an annual interest rate of more than 450 percent.
