David Hendry has made major contributions to many areas of economic forecasting. He has developed a taxonomy of forecast errors and a theory of unpredictability that have yielded valuable insights into the nature of forecasting. He has also provided new perspectives on many existing forecast...

There are simple well-known conditions for the validity of regression and correlation as statistical tools. We analyse by examples the effect of nonstationarity on inference using these methods and compare them to model based inference using the cointegrated vector autoregressive model. Finally...

Purpose: This paper aims to investigate the changes caused by the use of the enterprise resource planning (ERP) systems in the accounting of organizations at different levels: organizational structure; processes; and employees. Design/methodology/approach: The authors use a qualitative...

This article presents a comparator module which aims to compare, in real time, executions of organizational transactions with patterns of behaviors of these transaction executions, allowing the determination of which execution pattern is being followed by running each transaction. This is...

Nowadays there is a need for real-time awareness to assure conformity of organizational transactions to increase their reliability and to mitigate organizational risk. In this context, Continuous Assurance has assumed an important role as a management goal and in ensuring improved effectiveness...

Purpose – The paper aims to present a solution which makes it possible to control and audit organizational transactions in real time, helping to determine the degree of reliability with which they are carried out, mitigating the organizational risk. This auditing is made at a very low level of...

In this paper, we build a model for the yield curve in Germany, from 1975 to 2001, and use it to test the Lucas Critique. We provide a first application of the new general-to-specific automatic model selection algorithm embodied in PcGets to term structure odeling, and use new super exogeneity...

This study explores a new data set that contains information both on inputs and outputs for a sample of Portuguese secondary schools. An FDH reference technology is used to determine radial technical efficiency scores and slacks. Although it is known that there is no reason to assume convexity...
