A perspective on systems science and systems philosophy

A philosophical survey of systems science and systems philosophy is offered to provide an integrated, if personal, view of the ideas within the contemporary systems movement. An attempt is made to establish the validity of the two disciplines by meeting some of the criticisms levelled at the systems paradigm—particularly Sir Karl Popper's attacks on holistic thought. During the discourse the arguments that rage around reductionism and holism will be seen to contain some confused thinking, and it is suggested that the philosophy, theories and methods in systems science and systems philosophy offer a means for bringing reductionism and holism into a satisfactory alliance.     

Sustainable product-service systems

The concept of sustainable product-service systems has emerged recently, and is distinct from the ideas of cleaner production, eco-design and design for the environment. The concept goes beyond the environmental optimisation of products and processes and requires radical and creative thinking to reduce environmental impacts by a factor of between four and 20 times while maintaining an acceptable quality of service. Sustainable product-services consider alternative socio-technical systems that can provide the essential end-use function, such as warmth or mobility, that an existing product offers. Four types are outlined—result services; shared utilisation services; product-life extension services; and demand side management. Sustainable product-service systems attempt to create designs that are sustainable in terms of environmental burden and resource use, whilst developing product concepts as parts of sustainable whole systems, that provide a service or function to meet essential needs.     

Emergent complex systems

Complex systems are becoming the focus of important innovative research and application in many areas, reflecting the progressive displacement of classical physics and the emergence of a new and creative role for mathematics. This article makes a distinction between ordinary and emergent complexity and argues that a full analysis requires dialectical thinking. In so doing the authors aim to provide a philosophical foundation for post-normal science. The exploratory analysis developed here is complementary to those conducted with a more formal, mathematical approach, and begins to articulate what lies on the other side of that somewhat indistinct divide, the conceptual space called emergent complexity.     

Criteria of systems thinking

In science, the framework of systems theory—especially as developed over the past two decades—seems to be the ideal framework to express the emerging ecological paradigm. This article addresses the question: what is systems thinking—and more generally, holistic or ecological thinking—in modern science? The author identifies three key aspects of systems thinking that are characteristic in all the sciences. In presenting these aspects, the transition from the old to the new paradigm for each aspect is emphasized.     

Optimal fiduciary monetary systems

In a fiduciary monetary system, there is a social agreement to quote prices and denominate financial instruments in terms of a specific paper liability of the government. What are the best terms for this paper instrument? I investigate a system where the terms involve not only paying market interest rate on the monetary instrument, as proposed by many economists earlier, but also indexing the returns to the price level. The result is a homeostatic monetary system with a highly stable price level in the face of shifts in money demand and other disturbing influences. The paper examines the performance of the new fiduciary standard in equilibrium and disequilibrium models.     

Managing hybrid marketing systems

As competition increases and costs become critical, companies that once went to market only one way are adding new channels and using new methods - creating hybrid marketing systems. These hybrid marketing systems hold the promise of greater coverage and reduced costs. But they are also hard to manage; they inevitably raise questions of conflict and control: conflict because marketing units compete for customers; control because new indirect channels are less subject to management authority. Hard as they are to manage, however, hybrid marketing systems promise to become the dominant design, replacing the "purebred" channel strategy in all kinds of businesses. The trick to managing the hybrid is to analyze tasks and channels within and across a marketing system. A map - the hybrid grid - can help managers make sense of their hybrid system. What the chart reveals is that channels are not the basic building blocks of a marketing system; marketing tasks are. The hybrid grid forces managers to consider various combinations of channels and tasks that will optimize both cost and coverage. Managing conflict is also an important element of a successful hybrid system. Managers should first acknowledge the inevitability of conflict. Then they should move to bound it by creating guidelines that spell out which customers to serve through which methods. Finally, a marketing and sales productivity (MSP) system, consisting of a central marketing database, can act as the central nervous system of a hybrid marketing system, helping managers create customized channels and service for specific customer segments.     

Understanding multidimensional tax systems

Income tax systems are multidimensional, and ignoring their non-rate aspects can introduce bias into cross-country empirical estimation of the impact of taxation on economic outcomes. We analyze 10 non-rate tax system aspects, codified based on recent reports published by the Organisation for Co-operation and Development. We find that a single factor (which we call Dispersed Responsibility), related to the role of taxpayers and third parties in tax collection, can reasonably summarize the cross-country covariation, and offer it as a parsimonious measure of non-rate tax system dimensions for future empirical analysis. We also ascertain that a standard measure of trust in government is positively associated with greater administrator coverage and administrative assessment, as well as more serious sanctions for non-compliance. Ethnic heterogeneity, individualism, and a history of external conflict also can explain certain aspects of tax systems. We find that countries with greater trust in government score lower on Dispersed Responsibility. Finally, we find that adding a measure of the number of tax authority employees can eliminate the otherwise significant positive estimated coefficient of GDP per capita on the tax level, and attracts a significant positive correlation itself, suggesting that the extent of tax administration and enforcement is part of the story that explains the enduring statistical regularity between tax levels and per capita income.     

Legal systems and auditor independence

This paper examines whether an appropriate legal system, which is a combination of a legal regime and a damage apportionment rule, effectively enhances auditor independence. Economic and psychological hypotheses derived from a one-period game model in which the auditor may commit either a technical audit failure (resulting from the auditor’s inability to detect true output given a lack of audit effort) or an independence audit failure (resulting from the auditor’s intentional misreporting on false output) are tested. Three major findings are documented. First, auditor independence affects firm investment, which in turn affects audit effort. Under this strategic dependence, no single legal system can provoke audit effort, improve auditor independence, and encourage firm investment simultaneously. To enhance auditor independence and motivate investment, a legal system consisting of both a strict regime and a proportionate rule is preferred. Second, the strict regime induces more auditor independence than the negligence regime, while the proportionate rule induces higher audit effort than the joint-and-several rule. Finally, auditors’ moral reasoning and penalty for misreporting are both positively associated with their independence. In addition, the effect of moral reasoning on auditor independence diminishes as the level of penalty increases. These two results hold only when the legal systems that auditors face are considered.     

The systems analysis of conflict

This article is the outcome of a continuing programme of research involving systems engineers and political scientists. The ultimate aim is to explore the relevance of some of the methodologies of systems engineering to problems in the social sciences, especially the dynamics of domestic and international conflict. An initial exercise in modelling domestic conflict in terms of state equations (system dynamics) is described, although the study reflects the authors' interest in several approaches by the broadly based survey of past work and proposed diversification of their research.     

The promise--and peril--of integrated cost systems

Recent advances in managerial accounting have helped executives get the information they need to make good strategic decisions. But today's enterprise resource planning systems promise even greater benefits--the chance to integrate activity-based costing, operational-control, and financial reporting systems. But managers need to approach integration very thoughtfully, or they could end up with a system that drives decision making in the wrong direction. Operational-control and ABC systems have fundamentally different purposes. Their requirements for accuracy, timeliness, and aggregation are so different that no single, fully integrated approach can be adequate for both purposes. If an integrated system used real-time cost data instead of standard rates in its ABC subsystem, for example, the result would be dangerously distorted messages about individual product profitability--and that's precisely the problem ABC systems were originally designed to address. Proper linkage and feedback between the two systems is possible, however. Through activity-based budgeting, the ABC system is linked directly to operations control: managers can determine the supply and practical capacity of resources in forthcoming periods. Linking operational control to ABC is also possible. The activity-based portion of an operational control system collects information that, while it mustn't be fed directly into the activity-based strategic cost system, can be extremely useful once it's been properly analyzed. Finally, ABC and operational control can be linked to financial reporting to generate cost of goods sold and inventory valuations--but again, with precautions.     

A contextual model of information systems

The social-engineering of accounting and information systems has not kept pace with the awesome advances on the teachnical side. Attempts, such as human information processing systems, have proven too narrow and research efforts now are called for which include both the psychology of the user and the program conditions of the task. This paper outlines a model which combines both personal decision style and organizational technology to derive four distinct information systems styles — concise, cursory, diffuse, and elaborate - each of which is suited to a particular technology. The central idea is that accounting and information systems should be designed to be congruent with the organizational context which they serve.     

On measuring concentration in banking systems

Assuming a Pareto-type distribution of bank sizes, we investigate the effect of changes in Zipf's exponent () and the sample size on the behavior of different concentration indices, such as the 3-bank concentration ratio, the Herfindahl–Hirschman index and the top 5%-concentration ratio. We derive analytical relations between these concentration indices and investigate the elasticity of these indices to changes in and in the sample size N. We show different regimes under which each index can be used most appropriately. Our results are highly relevant for policymakers who rely on such concentration measures to derive public policy recommendations in banking.     

PAYG pension systems with capital mobility

This paper studies the design of an optimal pension scheme in an OLG and open economy model. The pension scheme provides a flat rate benefit and is based on the PAYG principle. It thus combines inter- and intra-generational redistribution. In this setting a number of symmetric economies are connected by an open and perfect capital market. When this number is very large, we have the small open economy case; when it is reduced to one, we have the case of autarky or perfect coordination. As the number of countries increases, there is more intragenerational redistribution, but less capital accumulation. JEL Code H55 · H87

Examining dual accounting systems in Europe

After adoption of International Financial Reporting Standards (IFRS) for consolidated financial statements by European-listed companies, a number of European countries still require the use of local standards in the preparation of legal entity financial statements. This study investigates whether this requirement can be explained by a low demand for high-quality financial reporting and an orientation of accounting toward the fulfilment of regulatory needs in these countries. Specifically, using accounting quality as an indicator of the focus of accounting on capital providers' needs, we compare accounting quality between countries permitting and prohibiting the use of IFRS in individual financial statements. Consistent with our expectations, we find that countries requiring the use of local standards in the preparation of legal entity financial statements exhibit a significantly lower level of accounting quality, both prior to and after IFRS adoption. We interpret these results as evidence that these countries have local standards more oriented toward the satisfaction of regulatory needs, rather than investors' needs. Furthermore, since differences in accounting quality persist after the implementation of IFRS, results suggest that firms in these countries face a lower demand for high-quality financial reporting.
