We compare single factor Markov-functional and multi factor market models for hedging performance of Bermudan swaptions. We show that hedging performance of both models is comparable, thereby supporting the claim that Bermudan swaptions can be adequately riskmanaged with single factor models....

Over the last years, it has become increasingly important for companies to create strategic business alignment (SBA), i.e., the degree to which employees understand, support, and are able to execute the companies’ strategic initiatives. This study provides insights into the way companies can...

The Net Present Value (NPV) approach is considered to be the right approach to study inventory and production systems. But, approximate average cost (AC) approach is widely used in both practice and theory. However, the opportunity cost interpretation of AC framework is not that straightforward...

Sustainable supply chain management (SSCM) is a rather new phenomenon in the Operations Management/Operations Research literature. In the design of Sustainable Supply Chains the increase of transparency across the chain is essential and can be obtained through identification and traceability....

This paper analyzes the properties of multivariate tests of purchasing power parity (PPP) that fail to take heterogeneity in the speed of mean reversion across real exchange rates into account. We compare the performance of homogeneous and heterogeneous unit root testing methodologies. The...

We will firstly outline the rationale of a public good game and explain the distinction between a continuous public good game and a threshold public good game. As a vast majority of experimental research in social psychology on public good games has used threshold public good games, we will then...

Fundamental changes in the competitive landscape triggered many firms to leverage and build competencies by focusing on transition processes towards internal network forms of organizing. These forms ameliorate exploration through knowledge creation and transfer. Internal networks are...

In this paper, we describe an extension of the methodology for explanation generation in financial knowledge-based systems, offering the possibility to automatically generate explanations and diagnostics to support business decision tasks. The central goal is the identification of specific...

This study proposes a test for mean-variance efficiency of a given portfolio under general linear investment restrictions. We introduce a new definition of pricing error or “alpha” and as an efficiency measure we propose to use the largest positive alpha for any vertex of the portfolio...

The debate on globalization has long been characterized by theses of institutional convergence and divergence. The emergence of Anglo-Saxon shareholder capitalism as the dominant paradigm since the start of the 1990s is associated with the pursuit of global strategies by Multinational...
