By any measure economists have played increasingly prominent roles in antitrust policy making, at least since the early 1970s. Indeed, the approach to the analysis of public policy toward business pioneered by Chicago school economists dominates the academic literature nowadays. According to the Chicago school's adherents, their insistence that antitrust be examined through the lens of price theory should have produced discernably ‘better’ (read pro-consumer) laws and ‘better’ law enforcement. This paper contends that economists have in fact not had a positive influence on antitrust policy, but have instead actively contributed to its use as a way of subverting competitive market forces. 相似文献

Plant-based precision nitrogen fertilizer application technologies have been developed as a way to predict and precisely meet nitrogen needs. Equipment necessary for precision application of nitrogen, based on sensing of growing wheat plants in late winter, is available commercially, but adoption has been slow. This article determines the expected profit from using a plant-sensing system to determine winter wheat nitrogen requirements. We find that plant-sensing systems have the potential to be more profitable than traditional nonprecise systems, but the existing system simulated was roughly breakeven with a traditional system. 相似文献

The objective of this paper is to evaluate the effect of Plant Variety Protection (PVP) on the productive merit/yield increases of US seed varieties. As an example, we use wheat varieties, which are and have been available as both protected and unprotected under PVP from both the public and private sectors. We find evidence that PVP has contributed to the genetic improvement of wheat, using varietal trial data from Washington State. As the private open‐pollinated varieties exist only because of PVP and are higher yielding, these results indicate a clear public benefit from PVP. 相似文献
