The Research Field “Modeling Business Information Systems”

The research field “Modeling business information systems” has a long tradition in the scientific discipline of Business and Information Systems Engineering (BISE). The present paper highlights research shaping the research field, discusses challenges impairing the development of the research field in the coming years, and outlines elements of a future research agenda.     

The role of accounting and the accountancy profession in economic development: A research agenda

A widely held view in the accountancy profession and the donor community is that accounting and the accountancy profession play an essential role in economic development. However, our review of the academic literature finds limited empirical research evidence on the relation between accounting and the accountancy profession and economic development, including specifically whether any such relation is causal, and if so, the direction of the causality. Entities, including those comprising the donor community, policymakers, and professional accountancy organizations (PAOs), need evidence on the question of whether and how the accountancy profession contributes to economic development. Such research could assist donors in evaluating the outcomes of interventions aimed at building the capacity of PAOs in emerging and developing economies and inform future interventions. We summarize the limited academic research addressing the relation between PAOs and economic development and present insights from two roundtables facilitated by the International Association for Accounting Education and Research. We identify research opportunities and research design considerations. We hope our paper will stimulate accounting researchers to advance this literature.     

Linking international entrepreneurship to uncertainty,opportunity discovery,and cognition

In this paper, we suggest a model of international entrepreneurship that links cognition, noticing opportunities, absorbing uncertainty, and bearing uncertainty, to international entrepreneurial action, which is important because of the increased interest in international entrepreneurship. The ways in which cognition affects opportunity identification are discussed to show how international entrepreneurs’ cognitive processes work in terms of identifying opportunities. We also explore the role of cultural differences, with respect to tolerance for bearing uncertainty, on international entrepreneurship. Finally, the model is used to identify areas for future international entrepreneurship research.     

Ambidexterity and Knowledge Strategy in Major Projects: A Framework and Illustrative Case Study

We develop a framework to analyze the multi‐level knowledge requirements of complex, major projects in terms of ambidexterity—the ability to exploit (refine existing knowledge) and explore (develop new knowledge). This is an important theme within the wider literature, yet practical operationalization methods for managers and researchers are not evident. We demonstrate the ambidexterity view through an illustrative case study of telecommunications delivery for the London 2012 Olympic Games and show how these concepts can be used to create an effective knowledge strategy. We offer a structure for the analysis of knowledge utilization in projects.     

Structural change in the world economy and forms of protectionism

Warnings about the dangers of protectionism are being heard from all sides at present. However, rehearsing the advantages of free trade and the drawbacks of protectionism is to little avail if it fails to take account of the limitations that the international context imposes on national economic policy. This article is an edited and updated version of a paper presented at a conference organized by the Evangelical Academy, Loccum, between 16th and 18th September 1988.     

Changes in insider ownership and changes in the market value of the firm

The empirically-observed cross-sectional relation between the level of insider share ownership and the level of firm value has often been interpreted to mean that a change in share ownership can lead to a change in firm value. Such an interpretation has been criticized for ignoring potential endogeneity. In this paper, we perform two sets of tests to circumvent this alleged endogeneity. First, we measure changes in value over the 6-day interval around announcements of insider share purchases and find that the cross-sectional variability in changes in value is described by a curvilinear relation between firm value and insider ownership where the value of the firm first increases, then decreases, as insider share ownership increases. Second, we conduct tests to determine (1) whether the insider purchases are a response to changes in firm characteristics that require a new optimal equilibrium ownership level or (2) whether insiders are purchasing shares to signal that the firm is undervalued. We find no evidence to support these interpretations. Overall, our results are consistent with a causal interpretation of the empirical relation between insider ownership and firm value.     

What drives corporate liquidity? An international survey of cash holdings and lines of credit

We survey chief financial officers from 29 countries to examine whether and why firms use lines of credit versus non-operational (excess) cash for their corporate liquidity. We find that these two liquidity sources are employed to hedge against different risks. Non-operational cash guards against future cash flow shocks in bad times, while credit lines give firms the option to exploit future business opportunities available in good times. Lines of credit are the dominant source of liquidity for companies around the world, comprising about 15% of assets, while less than half of the cash held by companies is held for non-operational purposes, comprising about 2% of assets. Across countries, firms make greater use of lines of credit when external credit markets are poorly developed.     

Effects of the Southward extension on the EC—Labour market

The European Community will be enlarged in the next few years by the accession of Greece, Portugal and Spain. Which will be the consequences for the labour market of the EC and the Federal Republic of Germany in particular?     

Implementing efficient market structure

Abstract. This article studies the design of optimal mechanisms to regulate entry in natural oligopoly markets, assuming the regulator is unable to control the behavior of firms once they are in the market. We adapt the Clarke–Groves mechanism, characterize the optimal mechanism that maximizes the weighted sum of expected social surplus and expected tax revenue, and show that these mechanisms avoid budget deficits and prevent excessive entry.
