The Lake Wobegon effect in student self-reported data

American Economic Review 1994
For over a decade, Garrison Keillor assured listeners of American Public Radio's A Prairie Home Companion that in the women are strong, all the men are good-looking, and all the children are above average (Judith Yaross Lee, 1991). Although we can offer no explanation for the women's strength and men's appearance, we may be able to shed light on the reports of exceptional achievement of Wobegon's children. Our research indicates that students tend to overstate their academic accomplishments, and that belowaverage students are less likely to report their achievements at all. This produces a Lake Wobegon effect in student selfreported data. Overstated achievement may produce biased estimates of the relationship between achievement and educational inputs, if overstatement is correlated with achievement. In economic education, the use of student self-reported data for empirical analysis is not uncommon. Both the National Assessment of Economic Education data base and the third edition of the Test of Understanding in College Economic data base use some self-reported data. In addition, some economic-education researchers develop their own data sets that include student self-reported data. Systematic reporting biases in data collection also create problems for empirical analysis. Nonrandom reporting has been documented as a potential problem in economic education. Students are more likely to report grading errors on examinations when the correction of these errors results in raising their grades (Dale 0. Cloninger and Robert Hodgin, 1986). Sample selection bias resulting from using an unrepresentative sample has been shown to result from data lost between pretests and posttests (William E. Becker and William B. Walstad, 1990), students' failure to take standardized tests (Claude Montmarquette and Rachel Houle, 1986), and selection procedures used to place students in experimental and control groups (John J. Siegfried and George H. Sweeney, 1980).

Employment and Wage Effects of Involuntary Job Separation: Male-Female Differences

American Economic Review 1986
Recent compositional changes in industrial and occupational structures have created technological displacement for many workers. Accompanying these institutional changes is increased foreign competition which has forced previously profitable firms to collapse. What happens to workers when competition and displacement create job loss? Many studies have found that with job termination, workers face long spells of unemployment and reentry into occupations with lower wages and fringe benefits; however, few studies have examined gender differences in the consequences of job termination. In fact, most research in this area has been case studies focusing solely on men. This study analyzes gender differences in employment and wages upon job termination. It answers the question, Do women fare better or worse than men upon job termination?
