the aim of this paper is to study the impacts of technological progress and efficiency change on the productivity growth of iran agriculture separated by provinces. the period of this study is from 2005-2014. first of all, the impacts of efficiency change and technology change were separated using dea and malmquist model. then, their impacts on productivity growth were studied. it was concluded...

  It is widely accepted that today’s technological world is moving in a much more speed than the past, which requires the skill of keeping up with the pace of change. This change and innovation is a must for all organizations. According to Shen (2008, p. 73), this change is trickier in the educational context, where "the nature of the knowledge, skills, and attitudes of those i...

We study the importance for climate policy of uncertainty concerning the gravity of climate change and thus the benefits of abatement. In particular, this uncertainty can have different effects on the benefits of early abatement and R&D. We explore these differences, which depend in large part on the curvature of the marginal abatement cost function—prudence, in other words. With convex margina...

This case tells the true story of a university employee who suffered from color blindness and who, although he had been an exceptional employee, was terminated when he could not read the color screens displayed by the newly installed PeopleSoft system. Moral outrage on the campus initiated a process that ultimately resulted in Hal Richards being offered another position in which his talents cou...

Technological change can be understood in terms of technological evolution. Because of this evolutionary aspect, a number of scholars have made analogies between technological innovation and biological evolution (Ziman, 2000). As technological advancement has played a crucial role in industrial development, almost every nation is concerned with monitoring technological change. Technology polici...

Constructing total factor productivity growth numbers free of the effects of business cycle variations is, as the large recent literature on the topic has shown, a difficult exercise. But the trend evolutions are clear. In most countries, TFP growth has been lower-often much lower-than it was before the mid-1970s. And the decrease in the underlying TFP growth rate appears to have been quite abr...

New technologies have allowed …rms to monitor low-skill workers more closely, thus reducing the power of these workers. We show that this ’power-biased change’may generate rising wage inequality and increases in the work intensity and unemployment of low-skill workers. JEL numbers: J31, O33

We develop a general equilibrium dynamic stochastic business cycle model augmented with uncertain total factor productivity shocks and investment specific technology shocks. Agents only observe noisy signals of these shocks, such as realized GDP, and update their beliefs each period about the fundamentals of the economy. We interpret this inability to perfectly observe the fundamentals of the e...
