This paper studies the implications for reserve lifetime and related quantities in a continuous time model of resource extraction under uncertainty. Both the resource price and the extracted amount are assumed to follow stochastic processes. Reserve lifetime is determined by the...

We propose a new model formulation for a three-echelon supply network design problem incorporating the concept of relocatable modular capacities. A robust supply network configuration must be determined based on uncertain demand. Furthermore, by incorporating the conditional value at risk...

In recent years, several U.S. government agencies have pioneered the use of artificial intelligence (AI) and other emerging technologies to improve the efficiency and accuracy of their 'responsibility determinations' (reviews of, among other things, contractor representations and certifications,...

This paper attempts to provide a decision-theoretic foundation for the measurement of economic tail risk, which is not only closely related to utility theory but also relevant to statistical model uncertainty. The main result is that the only risk measures that satisfy a set of economic axioms...

Researchers and practitioners who use Data Envelopment Analysis often want to incorporate several inputs and outputs in their model to consider as much relevant information as possible. However, too many inputs and outputs can result in the well-known dimensionality problem referred to as the...

This study develops and validates an ex-ante measure of firm-specific overall tax risk. We define tax risk as the potential that current actions or activities, or the failure to take actions or pursue activities, will lead to future tax outcomes that are different from expectations. Tax risk...

We examine whether internal auditing provides value to organizations by reducing risk. We compare the changes in risks between audited business units and matched non-audited units within the same company. This design allows us to isolate the importance of an internal audit while holding constant...

We examine companies' risk disclosure compliance with IFRS risk disclosure rules for the first fiscal year following the year 2007. For a sample of 383 firms from 20 European countries we find that average risk disclosure compliance is 62 percent only. Countries' enforcement strength is...

This paper examines the liquidity, Tobin's Q, and cost of equity effects from voluntary and mandatory IFRS adoption. In contrast to prior work, we focus on the firm level heterogeneity in the economic consequences, recognising that the level of uncertainty avoidance (UAI) in a country will...
