Price-dispersed preferences and C1 mean demand

In this paper we introduce the concept of price-dispersed preferences. Moreover we state conditions under which economies with price-dispersed preference distributions have a continuously differentiable mean demand function.     

Online customer relationships in the European financial services sector: A cross-country investigation

Reportedly, over the past 30 years there has been a general sense of willingness, on behalf of suppliers and customers alike, to develop increasingly close ‘emotional’ relationships based on trust. While buyers reward suppliers with brand loyalty, suppliers in turn develop strategies continually to energise this ‘connective’ relationship. As customers and suppliers increasingly become physically connected to one another via computer networks an important emergent issue is whether the nature of their relationship is changing as a result of transactions taking place across these networks. This paper discusses part of an exploratory research project designed to question the extent to which computer-based technologies that previously enabled the building of emotionally connective relationships through the analysis of customer data are instead facilitating anonymous transactional relationships. The project focuses on organisations in three European countriescolon; France, Germany and the United Kingdom. The broad aims are to explore whether consumer segments are emerging, that actually prefer the minimal personal interaction afforded by sophisticated new computer technology, and to examine the extent to which financial service organisations are responding to the demands of such segments. The paper includes an outline of the contextual background, followed by the research methodology and a discussion of the findings. Conclusions are drawn about the implications of these findings for both industry practitioners and academic researchers.     

A Novel Sampling Strategy for Surveying High Net-Worth Individuals—A Pretest Application Using the Socio-Economic Panel

High-wealth individuals are typically underrepresented or completely missing in population surveys. The lack of comprehensive national registers on high-wealth individuals in many countries challenged previous attempts to remedy this under-representation. In a novel research design, we draw on public data on the shareholding structures of companies as a sampling frame. Our design builds on the empirical regularity that high-wealth individuals are likely to hold at least part of their assets in the form of shareholdings. Based on data from over 270 million companies worldwide, we select all individuals who are both German residents and registered shareholders of companies. In a pretest, we interviewed 124 households from a gross sample of 2,000 anchor persons. Our analysis shows that values of shareholdings from register data highly correlate with individual ranks in the wealth distribution, that the quality of personal information, particularly the residential address, is sufficiently high for subsequent interviewing, and that the approach can fill a major data and research gap in the study of high-wealth individuals.     

Facilitative Leadership and the Challenge of Renewing Local Democracy in Italy

Participatory arrangements have become a popular way of addressing modern challenges of urban governance but in practice face several constraints and can trigger deep tensions. Facilitative leadership can play a crucial role in enabling collaboration among local stakeholders despite plural and often conflictual interests. Surprisingly, this style of leadership has received limited attention within debates linking urban governance and participatory democracy. We summarize the main insights of the literature on facilitative leadership and empirically develop them in the context of participatory urban governance by comparing recent participatory processes in two Italian cities. Whereas in one city facilitative leadership gradually emerged and successfully transformed a deep conflict into consensual proposals, in the other city, participatory planning further exacerbated pre‐existing antagonism, and local democratic culture was only later slowly reinvigorated through bottom‐up initiative. These diverging pathways explain how facilitative leadership is: (1) important for making things happen; (2) best understood as situated practices; (3) an emergent property of the practices and interactions of a number of local actors and (4) a democratic capacity for dealing with continuous challenges. Key to this style of leadership is understanding participatory urban governance as an ongoing democratic process.     

Explicit normative measurement of the degree of income inequality

Summary This paper deals with the problem how to measure the degree of inequality implied by a certain distribution of personal incomes. Traditional approaches to this subject, including statistical and welfare-based indicators, possess some important short-comings. As an alternative procedure this paper proposes the use of explicit normative concepts, by defining indicators which measure the divergence between an actual income distribution and a target or desirable one. Several indicators are given. The problem how to specify a target distribution is discussed, and a tractable procedure is indicated. This is applied to both actual and simulated income data. The examples serve only as illustrations of the approach proposed and use of the indicators for actual policy evaluation still requires more data.The author wishes to thank Henk van Metelen and Arend Stemerding for research assistance, and Simon Kuipers, Peter Nijkamp and Jan Tinbergen for their stimulating remarks on an earlier draft of this paper.

Short- and long-term participation tax rates and their impact on labor supply

Generous income support programs as provided by European welfare states have often been blamed to hamper employment. This paper investigates the importance of incentives inherent in the tax-benefit system for the individual decision to take up work. Using German microdata over the period 1993–2010, we find that recent reforms in Germany increased work incentives at the extensive margin measured by the participation tax rate (PTR), particularly for low-income individuals. Work incentives are even higher if the time horizon is extended to more than one year, pointing at an overestimation of the disincentives by standard measures. Regression analysis reveals that a decrease in the PTR increases the probability of taking up work significantly.
