This paper proposes a theory for the evolution of knowledge diffusion and growth over the very long run. A feedback mechanism between capital accumulation and knowledge spillovers creates a unified growth theory that explains a long epoch of (quasi-) stasis and an epoch of high growth linked by gradual economic take-off. It is shown how the feedback mechanism can explain the Great Divergence, t...

IEEE 802.11 Wireless Local Area Networks (WLANs) are a fundamental tool for enabling ubiquitous wireless networking. Their use has been essentially focused on best effort data transfer because the basic access methods defined in the 802.11 standard cannot provide delay guarantees to real-time flows. To overcome this limitation, the 802.11e working group has recently proposed the Hybrid Coordina...

Automated high-frequency trading has grown tremendously in the past 20 years and is responsible for about half of all trading activities at stock exchanges worldwide. Geography is central to the rise of high-frequency trading due to a market design of ‘‘continuous trading’’ that allows traders to engage in arbitrage based upon informational advantages built into the socio-technical assemblages ...

This dissertation studies the impact of learning about unobserved payoff-relevant variables on economic decisions. In chapter 1, I study a labor market in which employers learn about a worker’s unobserved skills by observing output. Skills evolve as a mean-reverting process with a trend that is potentially endogenous due to human capital accumulation. Output is additively separable in the worke...

This paper uncovers a counter-intuitive effect of international trade on female labor shares: whenever trade expands sectors intensive in female labor, female labor shares drop. When capital complements female labor more than male labor, the following mechanism operates: Expansions of sectors intensive in female labor come along with contractions of sectors intensive in male labor. Thus, male l...

Though we have abolished the death penalty, we have done next to nothing about developing a rational alternative method for dealing with the crime of murder. Life imprisonment, as such, is no better than a makeshift substitute, for it is based on precisely the same legal rationale: namely, that because murderers are, by definition, extremely culpable and extremely dangerous, they deserve to be ...

This study examined the development of individual social capital in a distributed learning community. Feld’s theory of focused choice predicts that the formation of network ties is constrained by contextual factors that function as foci of activities. In our research, we examined how group assignment and location could function as such foci to influence the development of individual social capi...

Inmany developing countries, lack of IT skills and human capital impede the potential of IT investments in organizations in developing countries [Lee, J. (2001). Education for technology readiness: Prospects for developing countries. Journal of Human Development, 2(1), 115–151]. This paper draws upon theories of humanand social capital, andknowledge, to explain enablers/obstacles for knowledge ...

Although developing the innovative behaviour of employees is considered to contribute to improving organisational efficiency and effectiveness, very little is known about innovative behaviour within the context of small to medium enterprises (SMEs). Human resource managers who are able to develop the innovative behaviour of employees create an opportunity in which an employee's behaviour can be...

Intellectual capital (IC) is organizational intangible asset which is frequently associated with performance. IC is commonly categorized into three core components: human capital, structural capital and relational capital. This study takes a step further in the evolution of the IC model for the hotel industry and divides relationship capital into two categories: End customer- relationship capit...
