A regulated upstream monopolist provides an input to firms in a downstream market. If the monopolist enters the downstream market, a natural concern is that it will act so as to raise its downstream rivals' costs. An offsetting incentive is that a higher downstream price will reduce demand for the input, which reduces the monopolist's profit. Conditions under which one incentive dominates the other are derived. The monopolist may desire to lower its downstream rivals' costs rather than raise them. These findings suggest that regulatory policy towards such downstream entry should not focus exclusively on the ability to discriminate. 相似文献

This study is an empirical test of the Easley, O'Hara, and Srinivas (1998) multimarket sequential trade model of stock and option markets. We employ two approaches to determine the information content of signed stock and option trades executed around quarterly earnings announcements. The first approach expands the vector autoregression (VAR) technique of Hasbrouck (1991a) to include signed option trade volumes and inter‐trade durations. Estimates from the VAR models provide insight into whether both equity and option trades are viewed as informative by the equity specialist. The second approach focuses on the information content of the earnings releases to determine whether signed equity and option trades executed prior to the announcements are informed. Results indicate that although informed traders prefer to transact in both markets around earnings announcements, option market transactions contain no incremental information. 相似文献

In this paper we discuss a project, still in progress, that moves away from a traditional lecture based educational pedagogy. We present a team taught approach to ethics teaching that embraces a progressive philosophy of education and is focused on the development of a discussion based learning community. We describe our primary pedagogical tools of case discussion and the development of student expert role assignments as a locus, and how they relate to the learning community, course content and course objectives. Finally, we provide our preliminary review of outcomes and emerging issues. 相似文献

No one would deny that sustainability is necessary for individual, business, and national survival. How this goal is to be
accomplished is a matter of great debate. In this article I will show that the United States and other developed countries
have a duty to create sustainable cities, even if that is against a notion of private property rights considered as an absolute.
Through eminent domain and regulation, developed countries can fulfill their obligations to current and future generations.
To do so, the governments must reject perfectly competitive free market capitalism and the absolute right to private property,
and more fully adopt social welfare capitalism as their economic system. The result will be a sustainable society that balances
democracy, individual rights and individual flourishing with the community’s flourishing. 相似文献

The competitive free-for-all that Congress envisioned in the 1996 Telecommunications Act has for the most part not appeared. The Act calls for two forms of regulatorily-assisted entry into local markets: lease of network elements and resale. The FCC has decreed that the charges for those elements and the resale discounts must emulate the costs of an ideally-efficient firm. This standard is in fact not efficient, and the FCC’s attempt to jump-start the entry of competitors in this way has short-circuited the competitive process itself and jeopardized achievement of the goals of the Act. 相似文献

金融危机席卷而来。2009年,麦肯锡咨询公司特别采访了多家大公司的14名领导人,请他们反思自己觉得从危机中学到了什么。当然,这次访谈也不想把他们的评论仅仅局限于当前的衰退,还请他们思考了在以前扭亏为盈的转型或危机期间曾经面临的挑战。 相似文献
