The impact of vertical integration on the wage bargain: new evidence

This paper considers the impact of vertical integration on the bargaining power relationship between employers and workers. We argue that vertical integration may have either a positive or a negative effect on the employer's position. The relationship between vertical integration of the firm and wages remains, therefore, an empirical question which this paper sets out to resolve. We do this using regression analysis and by employing a new measure of vertical integration. Our results suggest that contrary to the evidence of some previous studies, vertical integration can enhance employer bargaining power.     

Exploring convenience orientation as a food motivation for college students living in residence halls

The main objective of this paper is to study the concept of convenience orientation among young adults. A project was conducted among students living in residence halls, where information on their food motivation and behaviour was obtained. Data were collected using a self‐administered questionnaire filled out by 319 students. Convenience ap‐pears to be the most important food motivation followed by price, pleasure, health and concern about weight. Positive correlations were obtained between convenience and: deciding what to eat, having a varied diet and lack of time, all of which were considered to be difficulties associated with living in residence. Negative correlations were obtained between convenience and total time spent cooking per day and having learned to be autonomous in the kitchen. For male, the perception of eating well, having a varied diet, and maintaining weight were negatively correlated to convenience. For female, the correlation between convenience and the difficulty of eating enough was significant and positive. Negative correlations were obtained between convenience and fresh vegetables, potatoes, eggs, fresh meat, fresh fish and fresh poultry, herbal tea and alcohol. Positive correlations were obtained between convenience, frozen foods and foods brought from the parents’ home. Findings are discussed from both a health and a family perspective.     

Psychometric Properties of the Reidenbach–Robin Multidimensional Ethics Scale

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.

Climate for Scandal: Corporate Environments that Contribute to Accounting Fraud

We examine the governance characteristics, earnings quality, growth rates, dividend policy, and compensation structure of 97 firms recently under investigation by the Securities and Exchange Commission (SEC) for accounting fraud. Our results show that the corporate environment most likely to lead to an accounting scandal manifests significant growth and accounting practices that are already pushing the envelope of earnings smoothing. Firms operating in this environment seem more likely to tip over the edge into fraud if there are fewer outsiders on the audit committee and outside directors appear overcommitted.     

Implementing a corporate environmental strategy: establishing coordination and control within multinational companies

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. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.     

On the Hausdorff dimension of exceptional random sets generated by multivariate spacings

We consider multivariate spacings blocks in the usual sense (refer to Deheuvels (Z Wahrsch Verw Gebiete 64:411–424, 1983)). We consider the sets of exceptional points in the neighborhood of which such spacings are, infinitely often, unusually large. Our main result, in the spirit of Hawkes (Math Proc Camb Phil Soc 293–303, 1981), shows that these sets constitute random fractals, whose Hausdorff dimensions are explicitly evaluated.     

Alternative Specifications of the Institutional Constraints to Economic Growth - Or Why is there a Shortage of Electronic Engineers and Computer Scientists in Sweden?

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.     

Early internet IPOs versus subsequent entrants

This paper examines whether investors in early Internet IPOs earned superior returns to those who invested in later entrants. We document three differences between early public firms in a new Internet technology and their followers: underpricing, operating characteristics at the IPO, and stock price performance after the IPO. We find that there is value in going public relatively early in a new Internet technology. Specifically, long-term returns are significantly higher for the early entrants. We also find evidence, consistent with previous studies that examine hot IPO markets, that the early public firms have better operating characteristics at the IPO than later entrants.     

Identification, weak instruments, and statistical inference in econometrics

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.

Multiunit Pay‐Your‐Bid Auction with One‐Dimensional Multiunit Demands*

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.
