This paper aims to demonstrate the links between inequality, economic growth and technological change. The latter combined with human capital distinguishes skilled unskilled workers which leads rising inequality. Thus, we analyse theoretical empirical growth, change, school enrolment, openness, unemployment income Therefore, aim of this is show that change one key elements inequality dynamics. ...

Technological change is examined in a model of capital production to show that “creative destruction” can occur as an outcome of firm’s optimizing behavior. Capital systems are made up of components that are necessary for them to operate and that have uncertainty with respect to durability. For each type of technological change agents make a corresponding decision about whether to continue to u...

Medical technology is valuable if the benefits of medical advances exceed the costs. We analyze technological change in five conditions to determine if this is so. In four of the conditions--heart attacks, low-birthweight infants, depression, and cataracts--the estimated benefit of technological change is much greater than the cost. In the fifth condition, breast cancer, costs and benefits are ...

Information systems and other computer-based systems must continuously undergo change in order to reflect change in their environments. The present technology used to implement such systems, including models, methods, tools and languages, does not have an inherent understanding of the nature of evolution. The rigidity of existing systems is a hindrance for user requested enhancements. Propagati...

Technological changes in agriculture tend to alter the mass associated with a segment or subpopulation of the yield distribution as opposed to shifting the entire distribution upwards. We propose modeling crop yields using mixtures with embedded trend functions to account for potentially different rates of technological change in different subpopulations of the yield distribution. By doing so w...

The proportion of UK people with university degrees by age 30 more than doubled between those born in 1965-69 and those born ten years later. However, the age profile of the graduate wage premium remained largely unchanged across cohorts. We show that these patterns cannot be explained by composition changes. Instead, we present a model in which firms choose between centralized and decentralize...

This paper contrasts a dynamic and interactive view of technological change with the linear model of medical innovation that is still so deeply ingrained in many policy discussions. In particular, it focuses on the role of feedback mechanisms between the users and the developers of medical technology and the demand and supply forces (including competition among medical specialties) determining ...
