Competition was introduced into the electric utility industry with the passage of the Public Utilities Regulatory Policy Act (PURPA) of 1978. Increasing interest has appeared in structuring the PURPA purchase market into an auction system. This paper addresses the design issues associated with setting up such markets and introduces a simulation model to study them. The simulation analysis is guided by theoretical issues such as the alleged inefficiency of first-price auctions. We find that efficiency concerns raised about first-price auctions turn out to be less important than simple theoretical concerns would suggest. 相似文献

We examine the debt-equity decisions of startup firms using the Kauffman Firm Survey, the largest database of U.S. startups launched in 2004. To control for sample selection bias and the correlation among financing decisions, we employ a Bivariate Probit-Tobit model. Our results show that several firm characteristics such as growth prospects, firm size, tangible assets, and selling products, as well as owner characteristics such as net worth, experience, education and ethnicity explain the debt-equity decisions in the startup year. In addition, for firms that use debt, we document traits that explain the use of a particular type of business versus personal debt. Larger firms use more business debt, whereas home-based and growth firms use more personal sources of debt. Immigrants, owners who lack work experience and those who invest more time in the business tend to rely more on personal sources of debt. 相似文献

Multi-tenant architectures (MTAs) are considered a cornerstone in the success of Software as a Service as a new application distribution formula. Multi-tenancy allows multiple customers (i.e. tenants) to be consolidated into the same operational system. This way, tenants run and share the same application instance as well as costs, which are significantly reduced. Functional needs vary from one tenant to another; either companies from different sectors run different types of applications or, although deploying the same functionality, they do differ in the extent of their complexity. In any case, MTA leaves one major concern regarding the companies’ data, their privacy and security, which requires special attention to the data layer. In this article, we propose an extended data model that enhances traditional MTAs in respect of this concern. This extension – called multi-target – allows MT applications to host, manage and serve multiple functionalities within the same multi-tenant (MT) environment. The practical deployment of this approach will allow SaaS vendors to target multiple markets or address different levels of functional complexity and yet commercialise just one single MT application. The applicability of the approach is demonstrated via a case study of a real multi-tenancy multi-target (MT2) implementation, called Globalgest. 相似文献

Although there are encouraging trends, alcohol abuse continues to be a significant public health problem. Econometric studies of alcohol demand have yielded a great deal of information for alcohol abuse prevention policy. These studies suggest that higher alcohol taxes and stricter drunk‐driving policies can reduce heavy drinking and drunk driving. In this paper we explore the role physician advice plays in the campaign to prevent alcohol‐related problems. Compared to alcohol taxation, physician advice is a more precisely targeted intervention that does not impose extra costs on responsible drinkers. Compared to the resource costs of arresting, processing, and punishing drunk drivers, physician advice may be a lower‐cost intervention. To provide a basis for alcohol policy analysis, we use an alcohol demand framework to test whether physician‐provided information about the adverse consequences of alcohol abuse shifts demand to more moderate levels. There are three aspects of our alcohol demand model that complicate the estimation: (1) the dependent variable is non‐negative (it is a count variable—number of drinks consumed); (2) a non‐trivial number of sample observations have zero values for the dependent variable; and (3) because the data we use is non‐experimental, the treatment variable indicating receipt of advice from a physician may be endogenous. We implement an estimation method that is specifically designed to deal with these three complicating factors. Our results show that advice has a substantial and significant impact on alcohol consumption by males with hypertension, and that failing to account for the endogeneity of advice masks this result.

This article aims to identify and analyze the key benefits of adopting Guaranteed Maximum Price and Target Cost Contracts (GMP/TCC) over and above the traditional lump‐sum contractual arrangement through an empirical questionnaire survey conducted in South Australia and compared with the findings in Hong Kong. The Mann‐Whitney U Test indicated differences in perception between the two groups of respondents on the majority of the identified benefits. The study has provided an in‐depth understanding of the perceived benefits of the GMP/TCC scheme, hence leading to a wider application of those alternative integrated procurement strategies in both regions for reference by the construction community at large. 相似文献

One of the most widely discussed and highly agreed upon curricular issues for business and economic programs is the need to integrate international topics into the curriculum. Evidence indicates that little progress has been made in achieving this objective. To ignite the process of internationalizing the curriculum, a departmental study abroad program, based on the experience of Niagara University and Schiller International University, is proposed. Unlike most study abroad models, this approach systematically links the curricula of the host and domestic institutions. Faculty, who on most campuses are largely bystanders in the study abroad process, now assume a central role. This approach makes study abroad a major campus focus and a source of faculty development in international topics. 相似文献

The undeniable success of order-maintenance policing (also community policing or broken windows policing) is despite the deficiency in the theory which propelled the practice into policy: Wilson and Kelling's broken windows theory. We discuss what is wrong with the theory and why it nevertheless works when put into practice. 相似文献

This paper presents a model of innovations and endogenous economic growth with two main assumptions: first, the cost of searching
for innovations differs across innovations, and second, innovations take time to find. The paper shows that given these two
assumptions together, competition leads to patent races and to duplication of innovative activity. The paper then shows that
duplication significantly reduces the effect of scale on growth. It also shows that competitive R&D creates too much research
on easy innovations, and too little research on the difficult ones. Finally, the paper shows that risk sharing might increase
duplication and reduce growth. 相似文献
