Accounting researchers (and potentially others) generally select rather simple, lower-order, time-series models to develop proxies for earnings persistence. However, measures of persistence produced by such models are not related to characteristics of the firm's economic environment that are expected to influence earnings persistence. Using a sample of 162 calendar year-end New York Stock Exchange firms, we document the cross-sectional relations between a set of relatively constant, firm-specific, economic characteristics that are theoretical determinants of persistence and measures of earnings persistence derived from both lower-order and higher-order Autoregressive, Integrated, Moving-Average (ARIMA) models. When lower-order ARIMA models are used to generate measures of earnings persistence, the cross-sectional regression models measuring the association between persistence and economic determinants of persistence yield very low adjusted R2s. In sharp contrast, when differenced, higher-order ARIMA models are used to measure earnings persistence, adjusted R2s are in the 10–12 percent range. Moreover, independent variables such as capital intensity, barriers-to-entry, and product-type are all significant in the directions suggested by economic theory. Our results are consistent with Lipe and Kormendi (1994) who argue that higher-order ARIMA models do a better job of capturing the valuerelevance of current period earnings than lower-order models.

Approaches to risk governance are not homogeneous across organizations. Some organizations invest heavily in building formal and strategically focused enterprise-wide risk governance processes whereas others exhibit reduced formality and focus, allowing risk governance to be less structured. We argue that risk governance may best be described as a service dependent upon a network (or ecosystem) of participants who include users of risk information and providers who design and implement risk governance processes. Using a survey sample of 2,380 observations from 2011 to 2016, we find that external calls for enhanced risk governance are positively associated with risk governance processes having greater formality and strategic focus. We find this relationship is partially mediated by internal demands for enhanced risk governance. Further, we find that the positive association between internal demands and enhanced risk governance is reduced by resource constraints and that a risk-seeking attitude is negatively associated with enhanced risk governance.
