Correcting for the Missing Rich: An Application to Wealth Survey Data

It is a well‐known criticism that if the distribution of wealth is highly concentrated, survey data are hardly reliable when it comes to analyzing the richest parts of society. This paper addresses this criticism by providing a general rationale of the underlying methodological problem as well as by proposing a specific methodological approach tailored to correcting the arising bias. We illustrate the latter approach by using Austrian data from the Household Finance and Consumption Survey. Specifically, we identify suitable parameter combinations by using a series of maximum‐likelihood estimates and appropriate goodness‐of‐fit tests to avoid arbitrariness with respect to the fitting of the Pareto distribution. Our results suggest that the alleged non‐observation bias is considerable, accounting for about one quarter of total net wealth in the case of Austria. The method developed in this paper can easily be applied to other countries where survey data on wealth are available.     

A taxonomy of small- and medium-sized international family firms

This study develops a taxonomy of small- and medium-sized family firms that internationalise and discusses the different configurations of these firms based on firm culture (in terms of organisational orientations), firm strategy (in terms of differentiation, cost leadership and marketing standardisation) and firm structure (in terms of integration, centralisation and specialisation). Although the literature on international family firms has highlighted the significant role of organisational culture in firm internationalisation, the strategies and structures of international family firms and their consequences for performance have been disregarded. To examine the interplay of international family firm culture, strategy and structure, we employ a quantitative taxonomic approach that is rooted in configurational theory, analysing 504 Germany-based small- and medium-sized family firms. Different combinations of strategy, structure and culture result in different configurations of family firms and different levels of non-domestic performance. In considering these configurations, we aim to determine which combinations of strategies, structures and firm orientations are primarily applied by international family firms and whether these organisational configurations are successful. Our empirical findings suggest that there are four groups of firms: Domestic-Focussed Traditionalists, Global Standardisers, Multinational Adapters and Transnational Entrepreneurs. These configurations are clearly distinctive in terms of their structure, orientations and performance but differ less in terms of their strategies. Superior international (i.e. non-domestic) performance tends to be driven by a decentralised entrepreneurial approach.     

Integrating soft factors into the assessment of cooperative relationships between firms: accounting for reputation and ethical values

Alliances and other forms of cooperation between firms often promise great benefits, for example, by the exchange of knowledge or co‐specialization of resources. At the same time, the necessary actions to realize these benefits can augment vulnerability to opportunistic behaviour of partners. In addition to formal contracts to mitigate the resulting behavioural uncertainties, often, mechanisms, such as reputation or ethical values, are suggested as important supplements. However, when it comes to assessment of a specific cooperation opportunity, it is difficult to account systematically for the economic consequences of these ‘softer factors’. Therefore, this paper aims to surpass mere financial analysis of chance and risk and to integrate systematically both reputation and ethical values into an economic assessment of cooperative relationships. For this purpose, we develop a theoretical framework that is based on a simple‐decision model to account for reputation and ethical values of potential partners as drivers of behavioural uncertainty reduction. We also discuss how this framework can be used to assess cooperative relationships and illustrate these ideas with reference to the inter‐organizational accounting practices of a large drugstore chain and its suppliers.     

How Do Investors' Expectations Drive Asset Prices?

Based on an extension of the process of investors' expectations to stochastic volatility we derive asset price processes in a general continuous time pricing kernel framework. Our analysis suggests that stochastic volatility of asset price processes results from the fact that investors do not know the risk of an asset and therefore the volatility of the process of their expectations is stochastic, too. Furthermore, our model is consistent with empirical studies reporting negative correlation between asset prices and their volatility as well as significant variations in the Sharpe ratio.

Competitive supply behavior when price information is fuzzy

The theory of fuzzy sets is applied to the output decisions of a price-taking firm facing imprecise information about expected future prices. Accepting risk resulting from the randomness of prices, the manager is interested in expected profits only. Since the set of possible expected-price vectors is fuzzy, a suitable defuzzification strategy is defined in analogy to the pessimism-optimism index proposed by L. Hurwicz. It depends on the manager's willingness to accept surprises resulting from a deviation of the true expected prices from the values that guided output decisions. Despite a linear cost function, well specified solutions to the optimization problem are possible without resorting to capacity constraints.     

Wie viel Fertilität und Migration braucht Deutschland?

In der Diskussion um die demografische Entwicklung in Deutschland wird immer wieder danach gefragt, welche Maßnahmen möglich bzw. erforderlich sind, um den Bevölkerungsumfang bzw. die Altersstruktur der Bevölkerung auch längerfristig auf einem für die Stabilität der Gesellschaft angemessenen Niveau zu halten. In welchem Umfang wird die Bevölkerungsentwicklung durch ihre drei wichtigsten Komponenten Fertilität, Mortalität und Migration beeinflusst?Prof. Dr. Eckart Bomsdorf, 61, lehrt und forscht an der Wirtschafts- und Sozialwissenschaftlichen Fakultät der Universität zu Köln; Bernhard Babel, 27, Dipl.-Kaufmann, ist Wissenschaftlicher Mitarbeiter am Seminar für Wirtschafts- und Sozialstatistik der Universität zu Köln.
