This study investigates the economic outcomes of education for wage earners in Pakistan. This is done by analysing the relationship between schooling, cognitive skills and ability, on the one hand, and economic activity, occupation, sectoral choice and earnings, on the other. In Pakistan, an important question remains largely unaddressed: what does the coefficient on ‘schooling’ in conventional earning function estimates measure? Whereas human capital theory holds that the economic return to an extra year of schooling measures productivity gains acquired through additional schooling, the credentialist view argues that it represents a return to acquired qualifications and credentials, and a third view, the signalling hypothesis, suggests that it captures a return to native ability. This paper seeks to adjudicate between these theories u...
The problem with which this investigation is concerned is that students of unequal writing ability are frequently placed in the same beginning media writing classes in college journalism. It is difficult for a teacher to be effective when the ability of the students ranges from those who cannot write clear complete sentences to others whose work already appears in newspapers and magazines. The purpose of this study is to determine whether students who are ability grouped into slow—average and advanced groups do the same, better, or worse than heterogeneously grouped students. In the spring semester of 1987, students in Journalism 1345, Media Writing laboratory, at the University of Texas at Arlington, were given a pretest to determine how well they wrote a simple news story and a simple feature story. On the basis of that test, which w...
This paper considers a two-level vendor managed inventory (VMI) system comprising a distribution center (DC) and a retailer. Both the DC's and the retailer's replenishment decisions follow the order-up-to-level policy and aim at maximizing the profit of the overall system. We critically examine the potential of the DC's ability to modify delivery decisions, identify and quantify the cost factors that influence the DC's modification ability, establish a relationship between the DC's location and its modification ability, and show the trade-off between the DC's modification ability and related costs. Our analysis provides a new insight into the role of the DC and reveals the full potential of the VMI system. Our findings and their practical implications, demonstrated with the aid of computational examples, are helpful for enhancing the p...

In many countries through the industrial world the population is aging. Despite an increased life expectancy, improved living conditions, and better health status, the average time people spend in paid work is decreasing. There are several mechanisms of withdrawal from the labor force among elderly workers. Workers may leave the work force due to disability, unemployment, and early retirement. Many health problems, work related factors, life styles and individual characteristics are involved with early leaving of the labor force. In recent years, promoting work ability has been considered as an affirmative means to decrease work-related disability and early retirement. The concept of work ability expresses the interrelations between the productive potential of a worker, the worker’s individual characteristics, and physical and psychos...
The purpose of this investigation was to test the predictive value of the achievement goals theory on voluntary information selection. In a first study, 86 subjects could assess their performance after a motor test. The results showed that ego-oriented subjects chose normative information if they had a high perceived ability, and rejected information if they had a low one; task-oriented subjects chose objective information regardless of their perceived ability. In a second study, 108 subjects could use information during a training period. Data confirmed the prior results for ego-oriented subjects, and showed that task-oriented subjects preferred task information if they had a low perceived ability and objective information if they had a high one.
This paper develops two methods for estimating the effect of schooling on achievement test scores that control for endogeneity of schooling by postulating that both schooling and test scores are generated by a common unobserved latent ability. These methods are applied to data on schooling and test scores. Estimates from the two methods are in close agreement. We find that the effects of schooling on test scores are roughly linear across schooling levels. The effects of schooling on measured test scores are slightly larger for lower latent ability levels. We find that schooling increases the AFQT score on average between 2 and 4 percentage points, roughly twice as large as the effect claimed by Herrnstein and Murray (1994) but in agreement with estimates produced by Neal and Johnson (1996) and Winship and Korenman (1997). We extend the...
Education is negatively associated with mortality for most major causes of death. The literature ignores that cause-specific hazard rates are interdependent and that education and mortality both depend on cognitive ability. We analyze the education-mortality gradient at ages 18-63 using Swedish register data. We focus on months lost due to a specific cause of death which solves the interdependence problem, and use a structural model that derives cognitive ability from military conscription IQ scores. We derive the educational gains in months lost and the selection effects for each cause of death, and quantify the selection contribution of observed characteristics and unobserved cognitive ability. In a standard Cox model that controls for observed IQ, primary education was associated with 6 months lost when compared to secondary educati...
Data centres are the backbone of the digital economy and the widespread adoption of cloud services, business analytics and big data will continu to accelerate their demand. Because data centres consume a significant amount of energy, research efforts are needed to identify what facilitates actions to implement practices and technologies to either retrofit to or architect green data centres. This paper address this issu drawing from institutional, expectancy and motivation""ability theories and based on survey data collected from 96 data centres. The findings indicate that performance and effort expectancy form the strong order drivers and together with ability will lead to the implementation of practices and technologies that improve the energy efficiency of data centres. In addition, institutional isomorphic forces serve as ...
