We show that firms' ability to avoid taxes is greatly affected by the quality of the firm's internal information environment, with effective tax rates (ETRs) substantially lower for high internal information quality firms. Furthermore, we show that firms that experience an internal information quality improvement (reduction) are reducing (increasing) their ETRs. The effect of internal information quality on tax avoidance is strongest for firms in which information is likely to play a more important role. First, firms with high coordination needs because of their dispersed geographical or business industry presence benefit more from the reduced information asymmetry and improved information coordination between their various business units, allowing for more effective tax planning. Second, firms that are operating in a more uncertain environment are able to offset some of the negative effect of uncertainty on their ETRs through the quality of their internal information system. Because lower ETRs are obtained through better internal information quality, they do not come at the cost of increased risk in the tax positions taken: unrecognized tax benefits and ETR volatility are lower in high quality information environments.

Many different vendor selection models have been published in the purchasing literature. However there has been no systematic approach to compare the relative efficiency of the systems. In this paper we propose to use the concept of Total Cost of Ownership as a basis for comparing vendor selection models. We illustrate the comparison with the real life data set of the purchasing problem of ball bearings at Cockerill Sambre, a Belgian multinational company in the steel industry.Mathematical programming models outperform rating models and multiple item models generate better results than single item models from a Total Cost of Ownership perspective for this specific case study.

Beginning with Anderson, Banker, and Janakiraman (2003), a rapidly growing body of literature attributes the short-run asymmetric cost response to activity changes (i.e., sticky costs) resulting from short-run managerial choices. In this paper, we are agnostic on the theory of sticky costs. Rather, we focus on empirical tests of cost stickiness. We show that past decisions on cost structure, which determine the magnitude of costs controllable in the short-term, induce non-stationarity in the elasticity of Sales, General, and Administrative costs, affecting the interpretation of estimates from the standard specification used in the literature. We develop suggestions for how future research might control for the effects of cost structure. Empirically, we find that cost structure confounds results usually interpreted as cost stickiness reflecting short-run managerial actions. After adjusting for the effects of fixed costs, we find that the results are unstable across alternate subsamples. Our results provide evidence that long-run cost structure decisions impact our ability to detect short-term cost management decisions. JEL Classifications: M41; L42

About a decade ago, the constructive research approach (CRA) was proposed by Kasanen et al. (1993) as a specific opportunity for management accounting researchers to engage in solving problems relevant to managers. While the advocates of the CRA have argued in favour of its theoretical contribution potential and have shown that it satisfies the requirements of valid applied research, only very few studies using this particular approach have been published in major research journals. Our objective is to discuss the CRA methodology, both from a descriptive and from a prescriptive or normative perspective. We examine the research processes in two very different CRA studies, Degraeve et al. (2000b) and Tuomela (2000a), using the seven-step model suggested by Lukka (2000). We give practical exemplary methodological guidance for other researchers who wish to try out the CRA or obtain a better understanding of this methodology. While so doing, we also show that the CRA can provide researchers with interesting results obtained in a reliable and valid manner. In this way, we enhance the legitimacy of the CRA.
