The factor structure of the Multidimensional Ethics Scale (MES; Reidenbach and Robin: 1988, Journal of Business Ethics 7, 871–879; 1990, Journal of Business Ethics 9, 639–653) was examined for the 8-item short form (N = 328) and the original 30-item pool (N = 260). The objectives of the study were: to verify the dimensionality of the MES; to increase the amount of true cross-scenario variance through the use of 18 scenarios varying in moral intensity (Jones: 1991, Academy of Management Review 16, 366–395); and, to examine the items for measurement precision using item-response theory (IRT) methods. Results of confirmatory and exploratory factor analysis failed to conclusively support the hypothesized 3- (short form) or 5-factor (long form) structure; both instruments were instead dominated by a general factor. Item response theory analyses using Samejima’s (1969, Psychometrika Monograph Supplement 34, (4, Pt. 2)) graded response model revealed that many items in the 30-item pool performed very well, and suggested that a different collection of items be used to form a short-form version of the MES. Our proposed 10-item instrument includes more discriminating items than the 8-item version, and has the added advantage of including two items from each of the five ethical philosophies represented in the original 30-item pool.

This article presents the results of an empirical study that investigated coordination and control within multinational companies over six key aspects of their environmental strategy. Specifically, it first examines the level of centralization of these key issues. Second, it investigates whether there is a positive relation between three variables associated with organizational complexity and the level of centralization of the environmental issues. Statistical analyses of the data obtained from a sample of 98 North American multinationals were conducted. The study's results revealed that most companies have adopted a global environmental standard to govern their worldwide business activities that is supported by strong central controls over both environmental performance evaluation of facilities and decisions regarding the development of environmental programs. Results also revealed that there are limited links between organizational complexity and most aspects of the environmental strategy.

There is a shortage of engineers and scientists, in particular, electronic engineers and computer scientists, in Sweden. This shortage is argued to be one factor behind the structural weakness of Swedish industry in the 'high tech' area. The conventional explanation of the imbalance in the supply and demand for electronic engineers and computer scientists is focused on the incentives for the individual to demand higher education. These are argued to be low due to the relatively equal income distribution in Sweden and to high taxation. We find that the evidence given in support of this specification of the institutional problem is not convincing. Instead, we specify the institutional problem as having been a lack of opportunities to study electronics and computer science. With recent institutional changes in higher education, this problem is currently being tackled. Looking ahead, we see a new institutional problem emerging with a distinct gender bias. In order to increase the number of degrees awarded in electronics and computer science further, we will need to raise the interest of women in science and technology studies. This requires major institutional changes with regard to both the form and content of the educational programmes.  相似文献

Identification, weak instruments, and statistical inference in econometrics   总被引:1,自引:0,他引:1  
Abstract.  We discuss statistical inference problems associated with identification and testability in econometrics. We consider inference in non-parametric models and weakly identified structural models (weak instruments). We point out that many ill‐defined statistical problems, such as non‐testable hypotheses, occur in these areas and are typically associated with asymptotic approximations. In non‐parametric models, such problems include testing moments and inference under heteroscedasticity or serial dependence of unknown form. For weakly identified structural models, difficulties are typically associated with improper pivots, and we review recent developments aimed at proposing more reliable procedures, including alternative proposed statistics, bounds, projection, split‐sampling, conditioning, Monte Carlo tests.

An arbitrary number of units of a good is sold to two bidders through a discriminatory auction. The bidders are homogeneous ex ante and their demand functions are two‐step functions that depend on a single parameter. We characterize the symmetric Bayesian equilibrium and prove its existence and uniqueness. We compare this equilibrium with the equilibrium of the multiunit Vickrey auction and with the equilibria of the single‐unit first price and second price auctions. We examine the consequences of bundling all units into one package. We study the impacts that variations of the “relative” supply have on the equilibrium, on the bidders' average payoffs per unit, and on the efficiency of the equilibrium allocation.  相似文献

Historically, trading volume reported for NASDAQ stocks has been overstated vis‐à‐vis New York Stock Exchange (NYSE) stocks, both because of the dealer's participation in trades as a market maker and because of interdealer trading. Beginning in 1997, the Securities and Exchange Commission changed order‐handling rules and trade‐reporting rules, which may have reduced or eliminated the overstatement of NASDAQ trading. We examine trading volumes of firms changing from NASDAQ to the NYSE since 1997 and document that reported trading volume for NASDAQ stocks continues to be overstated. Moreover, the degree of overstatement is much larger for firms with high trading volume.  相似文献

Abstract:   We test the hypothesis that the passage of the Financial Services Modernization Act (FSMA) of 1999 has spillover effects cross‐nationally, using a sample of US, non‐US transactional (Australian, Canadian, and UK), and relationship (German, Japanese, Dutch, and Swiss) banks. Our results suggest that financial modernization in the US has limited cross‐national effects. We find strong evidence that US banks were affected favorably. Although we detect some evidence of significant reactions by banks in certain countries, a closer examination reveals that the reaction is most likely attributable to events in the respective countries during the event period. We do find, however, that non‐US transactional banks have been more likely to elect financial holding company status compared to relationship banks, suggesting they are positioning themselves to exploit the expanded opportunity set created by the FSMA. Nonetheless, the majority of elections have been made by US banks. In general, the results suggest that the respective banking markets are efficient in filtering events that are largely country‐specific with only limited implications for other international banks.  相似文献

The paper derives a consistent accounting framework for the treatment of inventories when measuring the productivity of a distribution firm. The average purchase price of an inventory item during an accounting period must be distinguished from its average selling price and these two average prices should be distinguished from the corresponding balance sheet prices. The accounting framework is implemented for a distribution firm which sold 76,000 separate items. The firm achieved a 9.6 percent per quarter total factor productivity growth rate over 6 quarters.The first author is a Professor of Economics at the University of British Columbia and a research associate of the NBER.
