This paper examines the impact of increasingly common congressional committee jurisdictional turf wars on policy outcomes. It develops a theoretical model that shows how legislators balance the benefits of expanded committee jurisdiction against preferred policy outcomes, yielding predictions that are different from the traditional committee-dominance theories. The theory predicts that a) senio...

“Intellectual property protection is important, but, almost of necessity, imperfect. It is harder and therefore more costly to define than conventional property, and by the same token, it is costlier to enforce intellectual property rights. In some cases, the inventor gets more than his marginal contribution, in other cases, less. Intellectual property protection strengthens dynamic efficiency ...

A new watermarking method for intellectual property (IP) protection is presented. The proposed method uses a uniquely generated stream of bits, known as a watermark, embedded into the self-test circuit to represent ownership. This scheme can detect the ownership rights of the IP provider even when the chip has been packaged. Experimental results show the proposed embedding technique can survive...

This paper studies the effects of market competition and intellectual property protection in emerging technologies such as software. In doing so, this research aims at contributing to the ongoing discussion on the possibility of broadening the scope of patent protection, in the EU, in order to cover many of the newly evolving technologies. The model indicates that optimal patent protection is c...

Intellectual property (IP) protection involves a trade-off between the undesirability of monopoly and the desirable encouragement of creation and innovation. Optimal policy depends on the relative strength of these two forces. We give a quantitative assessment of current IP policies. We focus particularly on the scale of the market, showing that as it increases, due either to growth or to the e...

Intellectual property copyrights are protected by means of patents and nondisclosure agreements. In many cases however copyright laws cannot be effectively enforced due to the difficulty of proving or even detecting infringement. This problem is addressed in the paper using a scheme known as watermarking. The method consists of implanting a semi-transparent unique signature in the circuit’s int...

Embedded Sensor Networks are deeply immersed in their environment, and are difficult to protect from abuse or theft. Yet the software contained within these remote sensors often represents years of development, and requires adequate protection. We present a software based solution for the Texas Instruments C5509A DSP processor which uses object-code encryption and public-key key exchange with a...
