Supply factors affecting the costs of obtaining schooling explain much the U-shaped trend in the skill premium in the U. S. across the twentieth century. Specifically, the direct costs fell dramatically in the early part of the century as a result of increased public funding and falling fertility rates during the high school movement. The foregone earning costs of schooling were also low for mi...

Common-sense folk psychology and mainstream philosophy of action agree about decisions: these are under an agent's direct control, and are thus intentional actions for which agents can be held responsible. I begin this paper by presenting a problem for this view. In short, since the content of the motivational attitudes that drive deliberation and decision remains open-ended until the moment of...

McFarland and Crouch (2002) reported substantial positive correlations (a) between the Implicit Association Test (IAT) and response speed and (b) between IATs assessing racism or self-esteem and ostensibly unrelated control IATs. Using an IAT measure in millisecond-difference score format, they concluded that the IAT was confounded with general cognitive ability. A reanalysis of these data usin...

In the early 1990s, a set of new techniques for manipulating mouse DNA allowed researchers to 'knock out' specific genes and observe the effects of removing them on a live mouse. In animal behaviour genetics, questions about how to deploy these techniques to study the molecular basis of behaviour became quite controversial, with a number of key methodological issues dissecting the interdiscipli...

The purpose of this study was to compare performance factors of youth soccer players according to position. A total of 101 high school soccer players were selected and were classified into goalkeeper (n=7), defense (n=37), midfield (n=39), and forward (n=18) positions. All subjects were subjected to the Wingate test for anaerobic capacity, shuttle run test for aerobic capacity, and pass, kick, ...

We introduce skill chaining, a skill discovery method for continuous domains. Skill chaining produces chains of skills leading to a salient event—where salience can be defined simply as an end-of-task reward, or as a more sophisticated heuristic (e.g., an intrinsically interesting event (Singh et al., 2004)). The goal of each skill in the chain is to reach a state where its successor skill can ...

China has witnessed rapid increases in the skill premium over last few decades. In this paper, we study short-run effect of capital goods imports on China. The surge imports, which embody advanced technology, can explain rising demand for We exploit regional variations import exposure stemming from initial differences structure and instrument growth using exchange rate movements. A city at 75th...

The focus of this review research is on skill mismatch rather than educational mismatch. Specifically, examines the definition, extent, measurement mismatch, and impact earnings, productivity, job satisfaction employed individuals. Skill occurs when a worker’s possessed skills are incompatible with required task-related skills. underutilization or overskilling arises an individual exceed those ...

When developing skills on a physical robot, it is appealing to turn to modern machine learning methods in order to automate the process. However, when no accurate simulator exists for the type of motion in question, all learning must occur on the physical robot itself. In such a case, there is a high premium on quick, efficient learning (specifically, learning with low sample complexity). Recen...

In this article, we present a unified treatment of and explanation for the evolution of wages and employment in the US over the last 30 years. Specifically, we account for the pattern of changes in wage inequality, for the increased relative wage and employment of women, for the emergence of the college wage premium and for the shift in employment from the goods to the service-producing sector....
