The Unaffordable Price Of Static Decision Making Models

The Unaffordable Price of Static Decision-making Models

At the 15th Viennese Workshop on Optimal Control and Dynamic Games, held in July 2022, experts in economics and the management sciences identified a concerning trend: static decision-making models, while less effective than dynamic ones, are becoming increasingly prevalent. This book aims to address the economic and social costs associated with reliance on static models and to demonstrate the advantages of applying dynamic approaches. Static models may be easier to formulate, but they often overlook the long-term consequences of decisions, promoting myopic practices that can lead to poor outcomes. In contrast, dynamic models foster a more comprehensive perspective, enabling foresight in decision-making – which is crucial for issues involving stock variables, such as pollution, reputation, and inventory. The book explores the limitations of static models, including their inability to capture long-term outcomes, history-dependent solutions, and the impact of abrupt contextual changes. It also highlights recent advances in dynamic modeling techniques that can enhance accuracy and help adapt to complex decision-making environments. By promoting the shift from static to dynamic models, this book aspires to open new research opportunities and provide valuable insights for researchers, students, policymakers, and managers in the fields of economics and the management sciences.

Price and Product-Mix Decisions Under Different Cost Systems

Philipp Plank analyses the question, what drives the quality of cost-systems and is the quality of cost-systems directly and at best positively related to the firms’ performance. In other words, is it worth investing in complex cost allocation systems or are there environmental and/or production settings in which less enhanced systems perform adequately. Using simulations, a benchmark firm (first-best solution) perfectly allocating cost to products is compared to firms implementing heuristic cost-allocation schemes (second-best solution) to identify the profit gap resulting from decisions based on limited information. Into this discussion, the idea of cost-stickiness is integrated, thereby indicating a new planning approach.
