The impact of product diversification strategy on the corporate performance of large Spanish firms

We analyze the impact of product diversification on performance. This topic has been discussed in the literature, and there is no consensus so far as to the significance or the direction of the impact. Performance is measured using Tobin's q for a sample of 103 large, non-financial Spanish firms (1992–1995). Diversification is measured by means of a categorical variable, as suggested by Varadarajan. The principal results indicate that the firms with intermediate levels of product diversification have the highest performance, while the firms with low and high levels of diversification show significantly lower performance, which performance is not significantly different between them.     

Tracking Can Be More Equitable Than Mixing

Parents and policy‐makers often wonder whether and how the choice of a tracked or mixed educational system affects the equality of opportunity. I answer this question by analyzing the influence of peers on future educational results. I define an equal opportunity policy as one that maximizes the average lifetime income of the worst‐off type of individuals in society (i.e., students from disadvantaged backgrounds). I find that tracking maximizes average lifetime income if the opportunity cost of college attendance is sufficiently high.     

Management Information System – A Tool for Corporate Sustainability

This paper represents the attempt to define a methodology that can evaluate the degree to which companies' information systems correspond to needs determined by the objectives of sustainability the firm imposes on itself. The result is the creation of a general model which define the correct approach to evaluating information systems – a model which should be adapted to the specificity of each single company which intends to adopt it. In the chart indicated, we obviously have not considered activities connected to the implementation of the survey system, which are particular to each company's situation. The first part of the paper consists of an overall introduction to the approach that has been used to assess the (MIS) of Granarolo, one of the Italian companies involved. The case study contains a profile of the company, the analysis of its MIS referred to the three dimensions of sustainability, and an evaluation of the strong points and issues to be developed. This approach to evaluate the gap between desired requirements of an information system for sustainability and current data available in a firm, has proved its consistency and usefulness. It helps to understand where data are, which dimensions, spheres, stakeholders account for and what is the level of integration between different information systems existing in the firm.     

Can incentives mitigate student overconfidence at grade forecasts?

Research shows that college students exhibit bias in their forecasts of exam performance. Most students are overconfident in their forecasts, academically weaker students are the most overconfident, and top-performing students are underconfident. The literature identifies negative repercussions of these biases, including inadequate preparation for exams. A recurring attribute of this literature is the absence of meaningful incentives for students to forecast accurately. We implement an extra credit scheme to incentivize accurate forecasts. Depending on how forecast bias is measured, the scheme mitigates bias by top-performing students and marginally mitigates bias by other students. Our results have several implications. First, we illustrate an extra credit tool instructors can use to incentivize students to make more thoughtful assessments of their future exam performance. Second, we show how the association between incentives and forecast bias differs across student groups. Finally, we show that results in this literature are sensitive to how bias is measured.     

The Role of Incentives in the Public Sector: Issues and Evidence

Using incentive pay to improve public-sector efficiency is animportant component of the UK government's public-service modernizationagenda. In this paper, we review the important issues in performancepay in the public sector, and summarize the evidence on itseffects. We consider how optimal incentives for public-sectorworkers may differ from those in the private sector and, ifthey do, what types of incentives are more appropriate for thepublic sector. We investigate the reasons for the infrequentuse of explicit incentives in the public sector. We summarizeevidence of particular relevance to the public sector, on issuessuch as the impact on output of incentive pay schemes, gamingand dysfunctional behaviour, multiple principals, intrinsicmotivation, and teamwork. Finally, we comment on the designof new policies being introduced in the UK public sector inthe light of the theoretical arguments and the evidence.     

Examining the Decision Process of Students' Cheating Behavior: An Empirical Study

This research examines the association between attitudes on cheating and cognitive moral development. In this research, we use Rest's (1979a) Defining Issues Test, the Attitudes on Honesty Scale (Authors) and Academic Integrity Index (Authors); the last two are adaptations of the DIT. A total of 220 students from three universities participated in the study (66 psychology majors and 154 business majors). The data indicate that 66.4 percent of the students reported that they cheated in high school, college, or both high school and college. Psychology majors scored higher than business majors on both the Defining Issues Test (Rest, 1979a) and the Attitudes on Honesty Scale (AHS, Authors). Using factor analysis, we found significant associations between students' ratings of the importance considerations present in the three cheating scenarios and their estimates of whether cheating would occur (i.e., the Academic Integrity Index). Finally, using logistic regression, we found that the scores on the Attitudes on Honesty Scale and Academic Integrity Index associate with the self-reported cheating behavior of college students.     

EXTENSIONS TO THE MULTIPLIER DECOMPOSITION APPROACH IN A SAM FRAMEWORK: AN APPLICATION TO VIETNAM

The aim of this paper is to provide an extension of a technique recently introduced by Pyatt and Round (2006) to decompose each element of the ‘global multiplier matrix’ in ‘microscopic detail’ in order to capture the linkages between each household groups’ income and the exogenously injected income of other accounts. The methodology we propose allows dividing the impact of exogenous injections into four different effects: direct-direct effect (D-D); direct-indirect effect (D-I); indirect-direct effect (I-D) and indirect-indirect effect (I-I). Results using the 2000 Vietnamese SAM show that the highest direct effects on the income of household groups are related to exogenous injections into the agricultural sector, while the highest indirect effects result from investing in other agriculture-related sectors such as, for example, food processing. Policy interventions focusing on the agricultural sector and on rural households will thus have the greatest effect on reducing the level of income inequality.     

Are More Innovative Firms Less Vulnerable to New Environmental Regulation?

Compliance with pollution limits and standards requires firms to implement adaptation processes that are not only costly themselves but also affect future profits in as much as they modify production systems and methods. This paper attempts to respond to the question of how technological knowledge moderates the effect that the implementation of a new environmental regulation has on the results of affected firms. The regulation selected for this study is the Integrated Pollution Prevention and Control Act (IPPC). A Multivariate Regression Model (MVRM) has been applied to the regulatory event. The most important implication of this paper is that technological knowledge prepares a firm for adapting to a greater environmental demand such as may be derived from a new regulation. This paper has been developed under the objectives of the CREVALOR Research Group (DGA-Spain). Moreover, it has been financed by the MEC-FEDER Research Project SEJ2005-07341.
