Many argue that Americans are not saving enough for retirement. Indeed, some point to increasing household debt loads and voice concern that Americans may have to work longer or lower their standard of living. But how much is "enough" saving? This AEI event will feature John Karl Scholz of the University of Wisconsin who, with his coauthors Ananth Seshadr of the University of Wisconsin and Surachai Khitatrakun of the ERS group, has developed an economic model to be able to predict the saving that is optimal for each individual. The data on actual saving behavior that is included in the study allows the authors to explore—much more exhaustively than has ever been done before—the extent to which Americans save too little. Following the presentation of the study's findings, other experts will assess its implications.
