Recently, time equation-based costing has been developed as a cost modelling approach in which activity times are calculated using time equations. Drawing on mathematical statistics, this paper develops a risk analysis approach and shows how it can be used to determine the impact of measurement...

This study compares ex ante estimates of the direct costs of individual regulations to ex post assessments of the same regulations. Our review of more than two dozen environmental and occupational safety regulations indicates that ex ante estimates of total (direct) costs have tended to exceed...

Cost estimations provided by ABC are hardly error free. Datar and Gupta (1994) state that the following three types of errors may occur: specification errors, aggregation errors and measurement errors. Reductions in specification and aggregation errors from more disaggregated and better...

In this paper we present finite T mean and variance correction factors and corresponding response surface regressions for the panel cointegration tests presented in Pedroni (1999, 2004), Westerlund (2005), Larsson et al. (2001), and Breitung (2005). For the single equation tests we consider up...
