This study begins a research program that examines how IT professionals cope with the threat of professional obsolescence. In answering this question, this study draws on theories of occupational stress, in particular the theory of conservation of resources (Hobfoll 2002; Hobfoll and Freedy 1993), to relate the threat of professional obsolescence with IT professionals’ coping strategies and the...

We use two stage optimal control techniques to solve some adoption problems under embodied technical change. We first solve a benchmark problem without learning behavior. At the date of switching, the consumption level is shown to drop, as the relative price of capital goes down (obsolescence). In such a case, the economy sticks to the initial technology, or immediately switches to a new techno...

This application note describes a high-speed, reconfigurable, full-precision Transposed Form FIR filter design implemented in the VirtexTM and Virtex-II series and SpartanTM-II family of FPGAs. The VHDL reference design provided with this application note is easily modified to change filter parameters including coefficients and the number of taps. By illustrating a design methodology for digita...

What effect have computers had on U.S. productivity growth? This paper shows that increased productivity in the computer-producing sector and the effect of investment in computers on the productivity of those who use them together account for the recent acceleration in U.S. labor productivity. In calculating the computer-usage effect, standard NIPA measures of the computer capital stock are ina...

The incentives that durability offers to a monopolist to price discriminate over time and the related difficulties that secondhand markets create in these situations have been well recognized in the economics literature. The conventional problem for the monopolist is that, having sold a durable good, there is an incentive to reduce price later to bring into the market those consumers who would ...

Background and Objectives: In the real world, the obsolescence items are some items that lose their value over time due to the emergence of new technology. Because of rapid changes in technology, inventory management of such items is considered in recent years. Moreover, suppliers try to encourage the retailers for purchasing an item before it is outmoded with some policies suc...
