Is the Optimal Labor Income Tax Progressive in a Unionized Economy?*

This paper concerns optimal nonlinear labor income taxation in an economy with union wage setting and endogenous hours of work. The purpose is to study the determinants of tax progression. We show that the optimal degree of progression of the labor income tax depends on the extent to which the government can influence the wage rate via tax policy as well as on its ability to redistribute income across individuals. In addition, the argument for progressive labor income taxation depends on whether hours of work are chosen by the employed themselves or the union.     

Combining data and text mining techniques for analysing financial reports

There is a vast amount of financial information on companies' financial performance available to investors in electronic form today. While automatic analysis of financial figures is common, it has been difficult to extract meaning from the textual parts of financial reports automatically. The textual part of an annual report contains richer information than the financial ratios. In this paper, we combine data and text mining methods for analysing quantitative and qualitative data from financial reports, in order to see if the textual part of the report contains some indications about future financial performance. The quantitative analysis has been performed using self‐organizing maps, and the qualitative analysis using prototype‐matching text clustering. The analysis is performed on the quarterly reports of three leading companies in the telecommunications sector. Copyright © 2004 John Wiley & Sons, Ltd.     

Relationships among pay inequity,perceptions of procedural justice,and organizational citizenship

This study explored relationships between employee dissatisfaction with pay, perceptions of procedural justice, and organizational citizenship behavior. It was hypothesized that pay inequity would be negatively related to citizenship, while favorable perceptions of procedural and interpersonal justice would be positively related. Results provided strong support for the hypotheses only with regard to a dimension of citizenship labeled “compliance.” Implications for employee behavior in the workplace and the expression of grievances are discussed; future research directions are also offered.     

Nothing is so good it can't be made better

The concept of continuous improvement can be viewed from the perspectives of the elimination of waste or the improvement of quality. The waste elimination approach attacks all forms of waste, whereas quality improvement uses the concept of total customer satisfaction. This article describes an eight-step model for continuous improvement that addresses waste elimination and customer satisfaction.

On the importance of matching strategic behavior and target market selection to business strategy in high-tech markets

Business strategy is fundamentally concerned with the actions required to create superior customer value in the firm’s target markets with the ultimate goal of achieving superior performance. Marketing theory suggests that two critical marketing activities required to achieve this end are: (1) the adoption of appropriate strategic behaviors (i.e., customer-oriented, competitor-oriented, technology-oriented) and (2) targeting of the appropriate market segments (i.e., innovators, early adopters, early majority, late majority, laggards). This study builds on prior research which demonstrates that the strategic behavior—firm performance relationship is contingent on the firm’s strategy by examining this relationship in high tech markets and by considering the incremental contribution of appropriate target market selection. Responses from 160 senior marketing managers in high-tech firms reveal strong support for our framework. Thus, this study provides useful guidance to executives and managers in high-tech firms regarding the steps that they should take to increase their probability of success.

Market-focused sustainability: market orientation plus!

The concept of sustainability is increasingly being addressed theoretically by scholars and practically by managers and policymakers. With this growing focus on sustainability efforts, marketing is in a unique position to elevate its focus from managing relationships with customers to strategically managing a broader set of marketplace issues. Overall, an organization achieves market-based sustainability to the extent that it strategically aligns itself with the market-oriented product needs and wants of customers and the interests of multiple stakeholders concerned about social responsibility issues involving economic, environmental, and social dimensions. To set the stage for marketing’s inquiry into sustainability efforts, I briefly review the concept of sustainability, compare it with corporate social responsibility, bring in stakeholders, argue for the notion of “market orientation plus,” and consider the possibility that the notion of what sustainability encompasses is converging in the marketing literature.
