Strategic planning of complex economic systems ∗

A major drawback of conventional models of the behavior of economic systems (and derived tools for policy intervention) is that the desire for tractability leads generally to a high degree of abstraction from reality. This article suggests an alternative, and arguably complementary, approach which engages specifically with economic complexity. The technique used is one of interactive spatial modelling over long time periods where the principle economic agents base decisions on incomplete heuristic information. For illustrative purposes the model has been calibrated on the basis of Senegalese data for 1981–91 and broad generic equations presented. The article argues that such a methodological approach holds out considerable advantages for strategic planning of sustainable economic systems. In particular it permits the direct engagement of noneconomic disciplines and client stakeholders in the planning process.     

An exploratory study of operational reasons to budget

Budgets are used widely but criticized, mainly for performance evaluation reasons. We find that organizations regard budgets as more important for planning and control than evaluation, thus proposing a rationale for their continued use irrespective of evaluation‐based criticisms. This finding is also important, because most extant budget research focuses on evaluation, suggesting a potential disconnect between budget research and practice. We also find that rolling forecasts are used in tandem with the annual budget in most organizations, and for the same reasons. This was unexpected, as coexistence suggests their adoption for different reasons.     

Publishing in accounting journals: A fair game?

Publication in the social sciences appears to have evolved into a game, played by four parties: the author, the reviewers, the editor and the bureaucrats using the simple criterion that a quality researcher publishes in quality journals. Acceptance rates for top quality journals now hover around the 10% mark. Something cannot be right with a system which creates so much apparent waste. Either too many authors are submitting substandard articles or too many reviewers are setting unrealistically high hurdles over which authors have to jump. Most of the literature has focussed on the unrealistically high hurdle rate explanation and also on the fallibility of reviewers and editors. The aim of this paper is to explore the issues of low acceptance rates as well as an increasingly lengthy publication process. The paper considers what is the purpose of publishing in academic journals and what are the motivations of authors, reviewers and editors. In order to inform both authors and reviewers of best practice, a summary of the extensive literature is given in the Appendix. The paper concludes with a survey of the suggestions that have been made to improve the publishing process in order to link back to the original purpose of publishing, that of communicating important results to inform public debate on major issues.     

Strategic profiles and performance: An empirical test of select key propositions

Competing theories on internal orientation versus external orientation are examined. The relevant theories are amalgamated and condensed into a number of competing propositions that are empirically tested. The findings suggest that the internally oriented businesses as well as the externally oriented businesses underperform the efficient, marketing oriented businesses.     

Strategic environmental policy and the accumulation of knowledge

In dealing with a transnational pollutant-emitting duopoly welfare-maximising policy makers face two negative externalities: imperfect competition and unpriced emissions. Strategic environmental policy models show that these externalities involve a trade-off between reducing pollution and allowing for rent-seeking of the respective firm. This dilemma usually results in a suboptimal internalisation of the negative externality emerging from emissions. Indeed, the conventional model setup includes an R&D stage that enables the firms to mitigate regulation costs. But the typical one period configuration ignores that R&D expenditures create knowledge capital which is, due to its inherent cumulativeness, also effective in following periods. Our model analyses the established trade-off in a two period setting and therefore allows for an investigation of intertemporal knowledge accumulation. We find that the intertemporal effects provide an incentive for a policy maker to set a higher tax rate compared to a one-period setup which lessens the magnitude of the suboptimal internalisation of emissions. Under certain conditions even a tax rate above the Pigouvian level is possible in period 1.     

Comment on the Kannai-Peleg impossibility theorem for extending orders

Recent work by Y. Kannai and B. Peleg shows that two appealing axioms for extending a linear order on a set of six or more elements to a weak order on the family of non-empty subsets of that set are mutually incompatible. This comment shows that a modest restriction of their monotonicity axiom is compatible for extension with a generalization of their other axiom provided that the linear order on the basic set is a well ordering.     

Small-sample inference with spatial HAC estimators

This paper examines the small-sample performance of spatial HAC (SHAC) estimators of the standard errors on parameters. We find that, in small to moderately-sized datasets, the use of HAC estimators may be recommended only with a relatively large degree of cross-sectional interdependence.
