Discipline Reform, School Culture, and Student Achievement
Does relaxing strict school discipline improve student achievement, or lead to classroom disorder? We study a 2012 reform in New York City public middle schools that eliminated suspensions for non-violent, disorderly behaviour. Math scores of students in more-affected schools rose by 0.05 standard deviations over three years relative to other schools. Reading scores rose by 0.03 standard deviations. Only a small portion of these aggregate benefit…
Cognitive Biases
Despite decades of research on heuristics and biases, evidence on the effect of large incentives on cognitive biases is scant. We test the effect of incentives on four widely documented biases: base-rate neglect, anchoring, failure of contingent thinking, and intuitive reasoning. In laboratory experiments with 1,236 college students in Nairobi, we implement three incentive levels: no incentives, standard lab payments, and very high incentives. We…
Measuring Aggregate Social Capital Using Census Response Rates
Despite the importance of social capital to political science research, conventional means of measuring it are subject to a range of problems, including nonresponse bias, declining validity over time, and/or a lack of conceptual coherence. We argue that, in the case of the United States, rates of response to the decennial census represent a powerful yet overlooked measure for aggregate social capital. In this research note, we elaborate a theoret…
Sandy the Rainmaker
The arrival of Hurricane Sandy within a week of the 2012 presidential election caused unprecedented disruption to the final days of the campaign and Election Day in areas that were affected. The precise impact of the storm on those areas hit hardest was not necessarily clear. Contrary to prior research on the effect of disasters on electoral outcomes, we find that the president's vote share was ultimately increased in storm-affected areas by abou…
Leadership and the Glass Ceiling
This study investigated influences of gender and ethnic group through the perspective of four leader behaviors deemed important by top managers and exhibited by 658 middle managers and executives in a large professional services business organization. As rated by subordinates, female and male executives were similar in that they generally engaged in greater amounts of the leader behaviors valued by top management than did male and female middle m…
Managerial motivation among MBA students
A longitudinal study of the effects of business school training on the motivation to manage of Masters of Business Administration (MBA) students was conducted using the forced‐choice version of the Miner Sentence Completion Scale (MSCS). Male MBA students had significantly higher levels of motivation to manage than female MBA students, with part‐time females registering the lowest managerial motivation levels among the MBA students. Managerial mo…
Factors Influencing Pay Decisions
This study investigated the pay raise distributions of allocators when their job situations make them particularly dependent on subordinates. The study compared recommended pay raises when the worker was a high or average performer, had high or low specialized expertise relative to the particular work unit circumstances, and either used no influence attempt, voiced an inequity complaint, or engaged in ingratiating behaviors involving complimentin…
Age, Abstract Thinking, and the American Concept of Person
Predictors of Job Status among Trained Economically Disadvantaged Persons
Based on interview data obtained from 50 trained economically disadvantaged persons and their supervisors on the first job after training, this study examined 10 potential predictors of job status (stayers versus leavers) among trained economically disadvantaged individuals. Appraised performance by the supervisor, satisfaction with the supervisor, and perceived ease of movement were significant differentiators among stayers and leavers. Only per…

The International Geophysical Year
rpHE International Geophysical Year 1957-58 will be written into JL history books because it recounts how man made his break through to study of space beyond atmosphere of his own planet Earth. But first a word of history itself. Early man could not but be aware of sun and moon. Indeed, we know that Egyptians among others derived their calendar from observing first moon, then sun. It was important in producing food that they should be able to pre…
