Ability of managers and other nonproduction professionals is key for the productivity of firms. Hence, the assignment of heterogeneous nonproduction workers across firms determines the distribution of productivity. In turn, the transmission of productivity differences into profit differences — resulting from product market competition — determines firms’ willingness to pay for higher managerial...

The allocation of children’s time among different activities may be important for their cognitive and non-cognitive development. In our work we exploit time use diaries from the Longitudinal Study of Australian Children to study the effect of time allocation across a wide range of alternative activities. By doing so we characterize the trade-off between the activities to which a child is expose...

This paper studies the labor market in Vietnam during the transition towards market economy (1993-2006): we show that the public-private sector wage gap markedly increased, but that wage inequality decreased overall. Our aim is to assess how much of this evolution can be explained by workers’ productive skills and their allocation between sectors. We use a simple, yet innovative, method that al...

Developing and maintaining undergraduate research programs benefits students, faculty mentors, and the university. Incorporating a research component along with a sound academic foundation enables students to develop independent critical thinking skills along with oral and written communication skills. The research process impacts valuable learning objectives that have lasting influence as unde...

Problems faced by engineering students involve multiple pathways to solution. Students rarely receive effective formative feedback on handwritten homework. This paper examines the potential for computer-based formative assessment of student solutions to multi-path engineering problems. In particular, a cognitive tutor approach is adopted and tested out on problems of truss analysis, studied in ...

A research lab is the workhorse of modern science. Running a research lab, whether it is a wet lab, dry lab, or both, is a complex and costly endeavor, which requires a talented team, solid funding, lab space, and a principal investigator (PI). The success of a lab is normally associated with its PI and, indeed, very much dependent on his or her scientific achievements (hence vision), productiv...

Increasingly, immigration policies tend to favour the entry of skilled workers, raising substantial concerns among sending countries. The ‘revisionist’ approach to the analysis of the brain drain holds that such concerns are largely unwarranted. First, sustained migratory flows may be associated with an equally large flow of remittances. Second, migrants may return home after having acquired a ...

The teaching of information technology in an ever-changing world at universities presents a challenge. Are courses taught as concepts, while ignoring hands-on courses, leaving the hands-on classes to the technical colleges or trade schools? Does this produce the best employees for industry or give students the knowledge and skills necessary to function in a high-tech world? At Georgia College &...
