Provision of safe injecting rooms (SIRs), needle exchanges and other harm minimisation schemes reduce mortality and other health risks that illicit drug users experience. However, SIRs diminish incentives to refrain from the use of drugs by reducing the risk of a key harmful consequence of use, namely the user's death. Moreover, such harm minimisation efforts are socially costly. Economic approaches to drug management balance benefits from harm minimisation against policy costs and the costs associated with a failure of community drug abstinence. This article shows that the economic case for SIRs disappears with conservative assumptions about adverse incentive effects of reduced mortality risks even when only modest weight is placed on drug abstinence objectives. 相似文献

Since the mid‐1980s U.S. domestic firms have faced significant increases in foreign‐based (i.e., import) competition as reductions in barriers to international commerce have resulted in markets and industries becoming increasingly global. Despite the growing and widespread importance of foreign‐based competition, the influence that such competition may exert on corporate diversification strategy is a question largely overlooked in the strategic management literature. This paper examines the impact of foreign‐based competition in a firm's core business on both the level and nature of a firm's diversification strategy at the corporate level in a panel dataset of U.S. firms over the period 1985–94. Our findings provide the first evidence that increased foreign‐based competition is indeed a statistically significant factor explaining both the reduced business‐level diversity and the increased strategic focus of U.S. firms that has been widely perceived over the past two decades.

This article provides an overview of mandated commodity programs in California, and summarizes and interprets existing evidence on their economic impacts. The analysis draws upon the recent book edited by the authors: The Economics of Commodity Promotion Programs: Lessons from California . New York: Peter Lang Publishing, April 2005. The book documents the institutional arrangements, summarizes the history of recent litigation, and presents the results of a number of benefit–cost studies of mandated commodity programs in California. The overwhelming conclusion from the studies reported in the article is that the programs have been very profitable for California's agricultural producers. 相似文献

The paper considers a Cliff–Ord type spatial model with a spatially lagged dependent variable and a row normalized weighting matrix with equal weights. We show that the 2SLS and OLS estimators are inconsistent unless panel data are available. The weighting matrix in question is one which would naturally be considered if all units are neighbors to each other, and there is no other reasonable or observable measure of distance between them. 相似文献

This article presents the results of a study on the evaluation criteria that companies use at several gates in the NPD process. The findings from 166 managers suggest that companies use different criteria at different NPD evaluation gates. While such criteria as technical feasibility, intuition and market potential are stressed in the early‐screening gates of the NPD process, a focus on product performance, quality, and staying within the development budget are considered of paramount importance after the product has been developed. During and after commercialization, customer acceptance and satisfaction and unit sales are primary considerations. In addition, based on the performance dimensions developed by Griffin and Page (1993), we derive patterns of use of various evaluative dimensions at the NPD gates. Our results show that while the market acceptance dimension permeates evaluation at all the gates in the NPD process, the financial dimension is especially important during the business analysis gate and after‐market launch. The product performance dimension figures strongly in the product and market testing gates. The importance of our additional set of criteria (i.e., product uniqueness, market potential, market chance, technical feasibility, and intuition) decreases as the NPD process unfolds. Overall the above pattern of dimensions' usage holds true for both countries in which we collected our data, and across firms of different sizes, holding different market share positions, with different NPD drivers, following different innovation strategies, and developing different types of new products. The results also are stable for respondents that differ in terms of expertise and functional background. The results of this study provide useful guidelines for project selection and evaluation purposes and therefore can be helpful for effective investment decision‐making at gate‐meetings and for project portfolio management. We elaborate on these guidelines for product developers and marketers wishing to employ evaluation criteria in their NPD gates, and we discuss directions for further research. 相似文献

Within the independent private-values paradigm, we derive the data-generating process of the winning bid for the last unit sold at multi-unit, sequential, asymmetric, English auctions. When the identity of the winner and the number of units won by each bidder in previous stages of the auction are observed, we demonstrate nonparametric identification and propose a semi-nonparametric estimation strategy based on orthogonal polynomials. We apply our estimator to daily data from fish auctions in Denmark. For single-unit supply, we use our estimates to compare the revenues a seller could expect to earn were a Dutch auction employed instead. 相似文献

Josef Steindl offers an innovative dynamic analysis of competition in Maturity and Stagnation in American Capitalism, with a key role for technical change. However, in his later writings he suggests that he had not gone far enough and that his account was not ‘sufficiently dynamic’, noting particularly his neglect of fundamental issues in technological development. Here, we critically examine the nature of technical change in Steindl’s analysis, pointing to ambiguities and contradictions that arise. Standard characterizations of the nature of technical change are then introduced and used to further integrate technical change into Steindl’s analysis of competition. 相似文献

Traditionally, the presence of serial correlation has been presumed to indicate an inefficient market for financial assets. As Latham [15] discusses, while the absence of serial correlation implies market efficiency, its mere presence does not imply inefficiency. Rather, market efficiency is a characteristic of security pricing. This study investigates pricing efficiency in the mortgage market. Using mortgage loan quotations for 343 institutions over a 71-week period, the empirical findings show that a wide variety of mortgage contracts are efficiently priced. 相似文献
