Two of the articles should be of particular interest to journalists interested in how education can help address issues of poverty. One, by economist Greg J. Duncan of Northwestern, Jens Ludwig an economist at the University of Chicago , and Katherine J. Magnuson of the School of Social Work at the University of Wisconsin, Madison, proposes an intensive two-year, education-focused intervention for all three- and four-year-olds that would charge fees on a sliding scale. The article is unusually specific. One key part of the idea is that the feds would offer incentives to states to participate rather than funding the program directly. The authors are more cautious than some advocates and researchers in that they don’t put a ratio on the return on investment. But they do say that the program’s $20 billion cost would be more than matched by the benefits—in the $2 or $3 per $1 spent range rather than the $7 to $14 that economists have calculated for other comprehensive programs in the past. They do, however, say such a program aimed at poor kids would reduce poverty by 5% to 15%, a very healthy gain.
