Measuring input-specific productivity change based on the principle of least action

In for-profit organizations, efficiency and productivity measurement with reference to the potential for input-specific reductions is particularly important and has been the focus of interest in the recent literature. Different approaches can be formulated to measure and decompose input-specific productivity change over time. In this paper, we highlight some problems within existing approaches and propose a new methodology based on the Principle of Least Action. In particular, this model is operationalized in the form of a non-radial Luenberger productivity indicator based on the determination of the least distance to the strongly efficient frontier of the considered production possibility sets, which are estimated by non-parametric techniques based upon Data Envelopment Analysis. In our approach, overall productivity change is the sum of input-specific productivity changes. Overall productivity change and input-specific changes are broken up into indicators of efficiency change and technical change. This decomposition enables the researcher to quantify the contributions of each production factor to productivity change and its components. In this way, the drivers of productivity development are revealed. For illustration purposes the new approach is applied to a recent dataset of Polish dairy processing firms.     

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.     

Single Market effects on productivity in the German insurance industry

The Single Market project of the European Commission was supposed to foster productivity growth in the financial service industry. We assess its consequences on productivity development in the German insurance industry, one of the largest insurance markets within the European Union, by applying Data Envelopment Analysis to a panel of German insurance companies. We estimate standard and bootstrapped efficiency scores for the years 1991 through 2006 and apply a test on scale efficiency based on bootstrapped statistics. Furthermore, we compute a Malmquist index and test for different types of productivity convergence across firms.     

Enumeration of Nash equilibria for two-player games

This paper describes algorithms for finding all Nash equilibria of a two-player game in strategic form. We present two algorithms that extend earlier work. Our presentation is self-contained, and explains the two methods in a unified framework using faces of best-response polyhedra. The first method lrsnash is based on the known vertex enumeration program lrs, for “lexicographic reverse search”. It enumerates the vertices of only one best-response polytope, and the vertices of the complementary faces that correspond to these vertices (if they are not empty) in the other polytope. The second method is a modification of the known EEE algorithm, for “enumeration of extreme equilibria”. We also describe a second, as yet not implemented, variant that is space efficient. We discuss details of implementations of lrsnash and EEE, and report on computational experiments that compare the two algorithms, which show that both have their strengths and weaknesses.     

Learning and Innovation in International Strategic Alliances: An Empirical Test of the Role of Trust and Tacitness

Drawing on knowledge-based, organizational learning, and social capital perspectives, we propose and test an integrated framework in which knowledge tacitness and trust act as mediating mechanisms in the relationship between partner characteristics and alliance outcomes. We distinguish between learning and innovation outcomes and suggest that while innovation may result from alliance learning, it can also be created by combining separate knowledge bases without learning from each other. We contend that tacitness and trust play differing roles in the pursuit of learning and innovation and test this proposition on a sample of 120 international strategic alliances.     

Top management team nationality diversity and firm performance: A multilevel study

This research reexamines the equivocal relationship between top management team (TMT) diversity and firm performance. Combining upper echelons theory with insights from institutional theory, we establish a new, timely dimension of TMT diversity—nationality diversity—and develop an integrated multilevel framework explaining how its performance implications vary across contextual settings. We find that nationality diversity is positively related to performance; and this effect is stronger in (a) longer tenured teams, (b) highly internationalized firms, and (c) munificent environments. More generally, our research demonstrates that the consequences of TMT diversity depend on the (1) specific attributes of diversity being considered and (2) firm and industry conditions under which strategic decisions take place.

Differences Between Management Philosophies Among American and Chinese Hotel Managers: A Cultural Comparison Between Las Vegas and Shanghai

The aim of this study is to ascertain, in an international tourism context, whether there are cultural discrepancies between hotel employees who have been educated and trained in a host country, and guests who have traveled to that country, given that each group is imbued with their own national culture. The findings indicate that not only do Thai frontline hotel employees have different expectations about the behavior of Japanese and Korean customers, but that the expectations of both customer groups concerning their own behavior differ from those of Thai employees. A significant gap was found in perceptions of actual behavior between the international customers and hotel staff, suggesting that cultural discrepancies are indeed present, but also vary by ethnicity. The scale of the discrepancy between Thai employees’ perceptions of Japanese tourists’ behavior, for example, was larger than in the case of the Korean customers. Comparison of the expectations of the two international customer groups also revealed strong differences.     

Corporate Disclosure of Material Information: The Evolution—and the Need to Evolve Again

This article by the former chairman of the FASB and the founder and executive director of the new Sustainability Accounting Standards Board (SASB) presents the rationale for and mission of the SASB. As the authors point out, both the Securities and Exchange Commission, which was created in 1934, and the Financial Accounting Standards Board, set up in 1973, emerged during times of low investor confidence to restore trust in the capital markets. And the institutional changes brought about by the creation of both the SEC and the FASB succeeded in eliciting new information for investors and in raising the standards by which such information was reported. But as the authors go on to argue, we now live in a different world, one in which the management of environmental, social, and governance issues is increasingly viewed as critical to the long‐run value creation of companies. And because today's corporate reporting fails to account in a systematic way for material non‐financial issues, it's time once again for the capital markets to evolve. The SASB aims to meet this need by creating sustainability accounting standards for use by public companies in disclosing a minimum set of material sustainability impacts for companies in over 80 different industries. As part of a natural evolution in disclosure, the SASB aims to achieve the same goal the SEC and FASB started with: to protect investors and the public.     

Measures of risk associated to regulations compliance: a laboratory experiment on the use of common-pool resources

The present research examined the influence of different risk perspectives by the use of four different target persons (who could be affected: abstract person, self, specific person, and specific others) and of four different questionnaire answer formats (rating, open percentage, open, and closed frequency) on risk assessments. It was assumed that subjects use two different systems in terms of probabilistic reasoning: a distributional approach for abstract targets leading to higher risk estimates and a singular approach for specific targets leading to lower risk assessments. According to unrealistic optimism (UO) research (showing higher risk assessments for an abstract person than for self), the assumption was that risk assessments for a specific (named) target lead to lower risk assessments compared to an abstract target. Further, common quantitative answer formats for assessing risk were compared to explore differences in risk estimates. The hypotheses were tested using data of a sample of 512 students from a Bavarian university. The frequently confirmed finding of UO could be replicated with both rating scale and open frequency scale, which appeared to be more sensitive compared to the other used scales. However, UO disappeared when the comparison target was specific. Further, risk assessments for an abstract target were highest within every answer format and lowest for specific targets. Furthermore, results revealed that the type of answer format has a moderating effect on the extent of the influence of risk perspective on risk assessments. Overall, this study gives evidence that both the chosen scale and the risk perspective strongly influence risk assessments. Results aim to contribute to the research fields of quantitative assessment of perceived risk. They suggest that probabilistic reasoning in regard to risk not only underlies motivational or cognitive ego-defensive mechanisms but is rather presumably caused by the use of different systems of inferential strategies.     

Towards a conceptual model of country market selection: Selection processes of retailers and C&C wholesalers

Abstract

International market selection is discussed in general, particularly in respect of decisions on evaluation stages, selection criteria and evaluation methods. The present analysis focuses on the configuration of country selection models, which has received little attention in international retailing research. In order to illustrate the special features of market selection in retailing, we have used an innovative approach. Following a review of general theoretical perspectives, a case study of the Metro Group addresses the process used, inter-country selection and country-specific selection, and also shows the role of corporate principles and firms' situational factors. Based on existing literature and the case study information, we propose a strategic approach in modelling country selection processes. Three steps in the construction of a selection model are discussed and related to corporate principles and situational factors of a retail firm. The analysis is a further step towards understanding the processes of retailing internationalization.
