International Trends in Income Inequality and Social Policy

In most OECD-countries income inequality has increased during the last two decades. In this paper, we investigate whether changes in the overall distribution of income can be attributed to social policy measures. For most (but not all) countries we find a possible relationship between changing welfare state policies (as measured by expenditure ratios and replacement rates) and changing income inequality. Especially the United Kingdom and the Netherlands combined an above-average rise in inequality with a reduction in the generosity of the welfare system.A more elaborate budget incidence analysis for the Netherlands indicates that in the period 1981–1997 inequality of disposable household income increased sharply. The two main forces behind this phenomenon were a more unequal distribution of market incomes and changes in social transfers. Fundamental social security reforms in the Netherlands indeed seem to have made the income distribution less equal. However, income inequality in the Netherlands is still below the OECD average at the end of the observed period.     

Boorstin's consumption community concept: A tale of two countries

The concept of consumption community, first proposed by historian Daniel Boorstin, claims that in the modern era of high mobility, people look not only to neighborhood as a basis for feelings of community but also to communality of consumption behavior (e.g., drinking the same brand of beer). The idea was tested cross-nationally by administering a newly devised psychological sense of community (PSC) scale to more than 100 adult respondents in Belgium and a like number in the U.S. The findings support Boorstin in that for both national samples, PSC values for consumption items were generally positive and consistent with social science theoretical expectations. Implications of the study findings are discussed for theory and social policy.

Zusammenfassung Das Konzept der Konsumgemeinschaft von Boorstin: Eine Geschichte von zwei Ländern. Das Konzept der Konsumgemeinschaft, erstmals durch den Historiker Daniel Boorstin vorgestellt, behauptet, da\ im heutigen Zeitalter hoher Mobilität der Einzelne sein Gemeinschaftsgefühl nicht nur durch seine Beziehung aus der direkten Nachbarschaft bezieht, sondern auch aus der Gemeinsamkeit bestimmter Konsumverhaltensweisen (z. B. das Trinken derselben Biermarke). Diese Idee wurde empirisch geprüft durch eine ländervergleichende Untersuchung, in der eine neu entwickelte psychologische Skala für den Gemeinschaftssinn bei jeweils einer Stichprobe von mehr als 100 erwachsenen Personen in Belgien und in den USA angewendet wurde. Die Ergebnisse stützen Boorstin insofern, als beide Länderstichproben zu Skalenwerten führen, die mit den theoretischen sozialwirtschaftlichen Erwartungen übereinstimmen.

Should the Central and Eastern European Accession Countries Adopt the EURO Before or After Accession?

I analyse the option of unilateral euroisation for Central and Eastern Europe. The thorny questions of losing seigniorage and losing the lender of last resort are explicitly addressed. It is found that the option of unilateral euroisation might be quite inviting for some countries. This is certainly the case if one takes into account the difficulties thrown up by the Maastricht–criteria. It is argued that unilateral euroisation provides an elegant way out of the catch of the official EMU-accession path. The EU has, however, expressed explicitly its enmity against euroisation. I think this is a policy error. It should be at least a genuine policy option for all countries concerned. At best the EU should stimulate euroisation by embedding it in a broader and more embracing framework that would support integration and ultimately accession to the EU of the whole of Central and Eastern Europe.     

Innovation-Oriented Culture in the Public Sector: Do managerial autonomy and result control lead to innovation?

This article examines the effect of specific new public management (NPM)-related characteristics to explain innovation-oriented culture within public sector organizations. According to NPM doctrines, an enhanced managerial autonomy combined with result control will stimulate a more innovation-oriented culture in such organizations. Using multi-country survey data of over 200 public sector agencies, we test for the influence of organizational autonomy, result control and their interactions, on innovation-oriented culture. High levels of managerial autonomy and result control have independent and positive effects. However, the interaction between high personnel management autonomy and high result control has a negative effect.     

How Do Investment Banks Value Initial Public Offerings (IPOs)?

Abstract:  We investigate the valuation and the pricing of initial public offerings (IPOs) by investment banks for a unique dataset of 49 IPOs on Euronext Brussels in the 1993–2001 period. We find that for each IPO several valuation methods are used, of which Discounted Free Cash Flow (DFCF) is the most popular. The offer price is mainly based on DFCF valuation, to which a discount is applied. Our results suggest that DDM tends to underestimate value, while DFCF produces unbiased value estimates. When using multiples, investment banks rely mostly on future earnings and cash flows. Multiples based on post-IPO forecasted earnings and cash flows result in more accurate valuations.     

Data accuracy's impact on segmentation performance: Benchmarking RFM analysis,logistic regression,and decision trees

Companies greatly benefit from knowing how problems with data quality influence the performance of segmentation techniques and which techniques are more robust to these problems than others. This study investigates the influence of problems with data accuracy – an important dimension of data quality – on three prominent segmentation techniques for direct marketing: RFM (recency, frequency, and monetary value) analysis, logistic regression, and decision trees. For two real-life direct marketing data sets analyzed, the results demonstrate that (1) under optimal data accuracy, decision trees are preferred over RFM analysis and logistic regression; (2) the introduction of data accuracy problems deteriorates the performance of all three segmentation techniques; and (3) as data becomes less accurate, decision trees retain superior to logistic regression and RFM analysis. Overall, this study recommends the use of decision trees in the context of customer segmentation for direct marketing, even under the suspicion of data accuracy problems.     

Sexual Harassments: Criteria for difining hostile enviorment

Sexual harassment in the workplace continues to be one of the most controversial and complex legal and ethical issues facing empolyers. The U.S. Supreme Court's June 1986 decisiion inMeitor Savings Bank v. Vinson, which applied Title VII of the Civil Reights Act to situations involving sexual harassment, is discussed. The Court's definition of hostile environment is reviwed, and federal court cases interpreting the Supreme Court's pronousncements are examined. The cases provide guidance on the kinds of situations that result in employer liability for sexual harassment. A primanry conclusion is that employers may easily avoid liability by exercising learned judgment and sound management practices.     

Revenue Effects of Tax Facilities for Pension Savings

Many countries have tax facilities for pension savings. These facilities are often associated with the application of the cash-flow treatment of pensions: pension contributions are tax-exempt, capital income of pension funds is tax-exempt, and pension benefits are taxed, but usually at a relatively low rate. This paper investigates the revenue effects of a cash-flow tax regime for pension savings by full present-value calculations. A comprehensive income tax system is used as a benchmark. We present an empirical analysis for the Netherlands as a typical example of a country with funded pensions. Our calculations show that current taxation of pensions implies a major tax revenue loss. For the year 2003, we estimate a fiscal pension subsidy of 1.4% to 1.5% of Gross Domestic Product (GDP).

Communities of Practice versus Organizational Climate: Which One Matters More to Dispersed Collaboration in the Front End of Innovation?*

Dispersed collaboration provides many benefits such as members' closeness to local cultures and markets and reachability of talent worldwide. Hence, it is no surprise that dispersed collaboration is frequently being used by product development teams. A necessary but not sufficient condition for innovation performance is the sharing of tacit, non‐codified and explicit, codified knowledge by the team. Situated learning theory, however, predicts that tacit knowledge sharing will be largely prevented by “decontextualization.” Therefore, increasing usage of dispersed collaboration will decrease levels of tacit knowledge—crucial to innovation and organizational performance—in the business unit. This research investigates the moderating role of mechanisms believed to enable tacit knowledge transfer in the front end of innovation. Using data from 116 business units, the moderating role of communities of practice and organizational climate on the relationship between the proficiency of dispersed collaboration and front end of innovation performance is investigated. Encouragement of communities of practice is found to moderate the relationship between proficiency of dispersed collaboration and front end of innovation performance on the business unit level. More specifically, proficiency of dispersed collaboration is not related at all to front end of innovation performance in business units with low support for communities of practice; but a positive relationship exists in business units with high support for communities of practice. This study does not provide support for the moderating effect of organizational climate on the relationship between proficiency in dispersed collaboration and front end of innovation performance. However, supportiveness of climate has a significant direct effect on front end of innovation performance. The findings of this study suggest that managers should simultaneously invest in increasing proficiency in dispersed collaboration and supporting communities of practice. Either one by itself is insufficient. Because of its significant direct effect, managers should also nurture an open climate favoring risk taking, trust, and open interaction.
