This paper attempts to explain the features of the recent U.S. economy by applying the transitional dynamics analysis of the R&D based endogenous growth model. It tries to explain the observed comovements of three variables: the relative wage rate of high skilled labour, the share of R&D workers and per capita output growth rate show a sharp decline in the ∗This paper is based upon the fourth c...

Does student employment pay off in the labor market after college? type of job matter? We use administrative data to describe amount and work for twenty cohorts students higher education Denmark. find large differences amount, especially jobs, by level field study. show that both skill content study-relevance matter earnings college. Having an additional year experience a requiring high or stud...

We introduce skill chaining, a skill discovery method for reinforcement learning agents in continuous domains. Skill chaining produces chains of skills leading to an end-of-task reward. We demonstrate experimentally that skill chaining is able to create appropriate skills in a challenging continuous domain and that doing so results in performance gains.

Current concerns over reforming engineering education have focused attention on helping students develop skills and an adaptive expertise. Phenomenological guidelines for instruction along these lines can be understood as arising out of an emerging theory of thinking and learning built on results in the neural, cognitive, and behavioral sciences. We outline this framework and consider some of i...

Abstract How does participating or moving to more upstream in the global value chains (GVCs) affect premium paid skilled compared unskilled labor within firms? In this paper, we develop a model of heterogeneous firms with intermediate trade and two skill inputs, which apply fair wage hypothesis predict changes according firms' GVCs activities. The predicts that backward GVC participation, as me...

We examined the controlling factors that allow a prompted skill to become autonomous in a discrete-trials implementation of Touchette's (1971) progressively delayed prompting procedure, but our subjects were rats rather than children with disabilities. Our prompted skill was a left-right lever-press sequence guided by two panel lights. We manipulated (a) the effectiveness of the guiding lights ...

Why are performance trade-offs so rarely detected in animals when their underlying physiological basis seems so intuitive? One possibility is that individual variation in health, fitness, nutrition, development or genetics, or 'individual quality', makes some individuals better or worse performers across all motor tasks. If this is the case, then correcting for individual quality should reveal ...

Transfer (i.e., the application of a learned skill in a novel context) is an important and desirable outcome of motor skill learning. While much research has been devoted to understanding transfer of explicit skills the mechanisms of skill transfer after incidental learning remain poorly understood. The aim of this study was to (1) examine the effect of practice schedule on transfer and (2) inv...
