Consequences of Debt Capitalization: Property Ownership and Debt versus Tax Choice

Public debts capitalize into property prices. Thus, they are a burden to the present generation who owns the devalued property. This largely neglected fact has important consequences for the tax versus debt choice. Property owners suffer more from the debt burden and, thus, have a stronger preference for tax financing of government spending than tenants. As a consequence of the resulting democratic struggle between property owners and tenants, higher property ownership rates in a jurisdiction lead to less debt financing. We provide empirical support for this hypothesis by analyzing a cross section of the 171 communities in the Swiss Canton of Zurich in the year 2000.     

Financing EU cohesion policy in Central and Eastern Europe

Following publication of Agenda 2000 the EU Commission has been criticised as overly optimistic on the budgetary consequences of the envisaged accession of a number of Central and East European Countries. This article briefly reviews the evolution of regional disparities within the EU and the impact of the Structural and Cohesion Funds on the present recipient regions. It then investigates whether it is financially feasible to extend EU regional policy to the five likely new CEEC member states without a major reform of the present system.     

Die Auswirkung von Globalisierung von Versicherungsmärkten aus medizinisch-demographischer Sicht

The opening of national life insurance markets is prevented by the fear, that the mortality experience might be too different to adopt one country’s principles to other markets. In this article the postwar German mortality is related to main cause of death groups, showing a simular development in relation to what was observed in the US and other countries. Comparing actual population life tables of Western European countries unvails that today’s differences in the death probabilities are only minor. From this point of view selling German life insurance contracts in neighborning countries like Austria or Switzerland would not create an unacceptable risk.     

Risk minimization in stochastic volatility models: model risk and empirical performance

In this paper the performance of locally risk-minimizing delta hedge strategies for European options in stochastic volatility models is studied from an experimental as well as from an empirical perspective. These hedge strategies are derived for a large class of diffusion-type stochastic volatility models, and they are as easy to implement as usual delta hedges. Our simulation results on model risk show that these risk-minimizing hedges are robust with respect to uncertainty and misconceptions about the underlying data generating process. The empirical study, which includes the US sub-prime crisis period, documents that in equity markets risk-minimizing delta hedges consistently outperform usual delta hedges by approximately halving the standard deviation of the profit-and-loss ratio.     

The Social Network Position of Lead Users

The field of lead user research has seen a great deal of attention from academics and practitioners alike. However, we still lack a full understanding of the nature of users with high potential for innovation. In this paper, we employ a social network perspective on lead users. Increasing the realism of our research in three empirical studies with different empirical settings and methods, we provide robust evidence that lead users have a distinctive social network position: They exhibit an unusually high level of “betweenness centrality,” meaning that they are positioned as bridges between different social groups. This finding has two major implications for lead user theory. First, it consolidates seminal conceptual work on lead users and their embeddedness in social networks. And second, the findings extend and validate prior work on the social network perspective of lead users by combining theoretical insights from cognitive psychology, research on creativity, and network theory. As the social network positions of individuals can be mapped quickly and at low cost with modern Web mining tools, our findings may point to a new and readily applicable approach for the efficient and effective identification of lead users in real‐life projects, an aspect that is usually emphasized as the most crucial activity in lead user projects.     

Value Creation by Toolkits for User Innovation and Design: The Case of the Watch Market

This study analyzes the value created by so-called "toolkits for user innovation and design," a new method of integrating customers into new product development and design. Toolkits allow customers to create their own product, which in turn is produced by the manufacturer. In the present study, questions asked were (1) if customers actually make use of the solution space offered by toolkits, and, if so, (2) how much value the self-design actually creates. In this study, a relatively simple, design-focused toolkit was used for a set of four experiments with a total of 717 participants, 267 of whom actually created their own watches. The heterogeneity of the resulting design solutions was calculated using the entropy concept, and willingness to pay (WTP) was measured by the contingent valuation method and Vickrey auctions. Entropy coefficients showed that self-designed watches vary quite widely. On the other hand, significant patterns still are visible despite this high level of entropy, meaning that customer preferences are highly heterogeneous and diverse in style but not completely random. It also was found that consumers are willing to pay a considerable price premium. Their WTP for a self-designed watch exceeds the WTP for standard watches by far, even for the best-selling standard watches of the same technical quality. On average, a 100% value increment was found for watches designed by users with the help of the toolkit. Taken together, these findings suggest that the toolkit's ability to allow customers to customize products to suit their individual preferences creates value for them in a business-to-consumer (B2C) setting even when only a simple toolkit is employed. Alternative explanations, implications, and necessary future research are discussed.     

Incorporating positions into asset pricing models with order-based strategies

The paper addresses the problem of agent-based asset pricing models with order-based strategies that the implied positions of the agents remain indeterminate. To overcome this inconsistency, two easily applicable risk aversion mechanisms are proposed which modify the original actions of a market maker and the speculative agents, respectively. Here the concepts are incorporated into the classical Beja–Goldman model. For the deterministic version of the thus enhanced model a four-dimensional mathematical stability analysis is provided. In a stochastic version it is demonstrated that jointly the mechanisms are indeed able to keep the agents’ positions within bounds, provided the corresponding risk aversion coefficients are neither too low nor too high. A similar result holds for the misalignment of the market price. We wish to thank two anonymous referees for their observations and detailed comments.

技术时代的不确定性与美国证券监管的未来

美国证监会缺乏相关的技术对策,它还不甚了解信息技术的发展趋势及其对美国证券市场的影响,也不清楚技术进步对证监会监管职能的作用及影响.因此,证监会在对全国证券市场进行监管时,无法制定有效的技术路线.
