Although both economists and psychometricians typically treat them as interval scales, test scores are reported using ordinal scales. Using the Early Childhood Longitudinal Study and the Children of the National Longitudinal Survey, we examine the effect of order-preserving scale transformations...

We address the ordinality of test scores by rescaling them by the average eventual educational attainment of students with a given test score in a given grade. We show that measurement error in test scores causes this approach to underestimate the black-white test score gap and use an...

We show that, without strong auxiliary assumptions, it is impossible to rank groups by average happiness using survey data with a few potential responses. The categories represent intervals along some continuous distribution. The implied CDFs of these distributions will (almost) always cross...

Among college graduates, teachers have both low average AFQT and high average risk aversion, perhaps because the compression of earnings within teaching attracts relatively risk-averse individuals. Using a dynamic optimization model with unobserved heterogeneity, we show that were it possible to...

We use the exchange between Kearney/Levine and Jaeger/Joyce/Kaestner on “16 and Pregnant” to reexamine the use of DiD as a response to the failure of nature to properly design an experiment for us. We argue that 1) any DiD paper should address why the original levels of the experimental and...

Under the standard competitive model, a tax change affecting workers with highly inelastic labor supply, will lower earnings by the entire nominal employer share of the tax increase. If wages play a motivational role but the market still clears, the range of possible outcomes is broader but...

We propose a model that combines statistical discrimination and educational sorting that explains why blacks get more education than do whites of similar cognitive ability. Our model explains the difference between blacks and whites in the relations between education and AFQT and between wages...

Since applying for jobs is costly, workers prefer applying where their employment probability is high and, therefore, to jobs attracting fewer higher quality applicants. Since creating vacancies is expensive, firms create more vacancies when job-seeking is high. Our model captures these ideas...

We argue that Labor Market Segmentation theory is a good alternative to standard views of the labor market. Since it is sometimes argued that labor market segmentation theory is untestable, we first consider the uses of theory and the attributes of a good theory. We then argue that labor market...

We analyze a firm's job-assignment and worker-monitoring decisions when workers face occasional crises. Firms prefer to assign good workers to a difficult task and to not employ bad workers. Firms observe failures but only observe successfully resolved crises if they monitor the worker. If...
