David Card and Alan B. Krueger have already made national news with their pathbreaking research on the minimum wage. Here they present a powerful new challenge to the conventional view that higher minimum wages reduce jobs for low-wage workers. In a work that has important implications for public policy as well as for the direction of economic research, the authors put standard economic theory to the test, using data from a series of recent episodes, including the 1992 increase in New Jersey's minimum wage, the 1988 rise in California's minimum wage, and the 1990-91 increases in the federal minimum wage. In each case they present a battery of evidence showing that increases in the minimum wage lead to increases in pay, but no loss in jobs.A distinctive feature of Card and Krueger's research is the use of empirical methods borrowed from the natural sciences, including comparisons between the "treatment" and "control" groups formed when the minimum wag

The Mystery of Hollow Places is a gorgeously written, stunningly original novel of love, loss, and identity, from debut author Rebecca Podos.All Imogene Scott knows of her mother is the bedtime story her father told her as a child. It’s the story of how her parents met: he, a forensic pathologist; she, a mysterious woman who came to identify a body. A woman who left Imogene and her father when she was a baby, a woman who was always possessed of a powerful loneliness, a woman who many referred to as “troubled waters.”Now Imogene is seventeen, and her father, a famous author of medical mysteries, has struck out in the middle of the night and hasn’t come back. Neither Imogene’s stepmother nor the police know where he could’ve gone, but Imogene is convinced he’s looking for her mother. And she decides it’s up to her to put to use the skills she’s gleaned from a lifetime of reading her father’s books to track down a woman she’s only known in stories in order to find him and, perhaps, the an
