How do normalization schemes affect net spillovers? A replication of the Diebold and Yilmaz (2012) study

2019

Abstract This paper replicates the Diebold and Yilmaz (2012) study on the connectedness of the commodity market and three other financial markets: the stock market, the bond market, and the FX market, based on the Generalized Forecast Error Variance Decomposition, GEFVD. We show that the net spillover indices (of directional connectedness), used to assess the net contribution of one market to overall risk in the system, are sensitive to the normalization scheme applied to the GEFVD. We show that, considering data generating processes characterized by different degrees of persistence and covariance, a scalar-based normalization of the Generalized Forecast Error Variance Decomposition is pref…

Quo vadis, internal auditing? A vision for internal auditing in 2030

2023

We aim to respond to calls in international auditing (IA) literature and to the current changes in the IA field by describing the driving forces and vision of the future for IA in the year 2030. The goal was to prompt in-depth discussion informed by the divergent views of experts. As a contribution, we identify three key driving forces: prolific data and its application, globalization and new value chains between organizations. Further, the study reports a vision for the future of IA. By surveying a wide range of stakeholders, including the board, management, internal auditors, teachers and a legislator, we expand on the views in earlier literature regarding IA, IA developments and the appl…
