Economists often estimate a subset of their model parameters outside the model and let the decision-makers inside the model treat these point estimates as-if they are correct. This practice ignores model ambiguity, opens the door for misspecification of the decision problem, and leads to...

Economists often estimate economic models on data and use the point estimates as a stand-in for the truth when studying the model’s implications for optimal decision-making. This practice ignores model ambiguity, exposes the decision problem to misspecification, and ultimately leads to...

This paper studies the behavior of two firms after a new investment opportunity arises. Examples of such an investment are technology adoption or market entry. Firms either invest immediately or wait until market uncertainty is resolved. Two types of separating equilibrium are possible when...

Aus Sicht von Keynes hängt das Erfolgspotenzial der Marktwirtschaft nicht nur von der staatlichen Wirtschaftspolitik ab, sondern ebenso vom Wirken vorausschauender Unternehmer:innen. Diese sollen sich seiner Meinung nach dadurch auszeichnen, dass sie trotz allgegenwärtiger Unsicherheit...

Uncertain future development presents a significant challenge during the distribution strategy planning process. Traditional planning approaches, reliant on creating potential scenarios and assigning probabilities, often struggle due to future developments' inherent unpredictability, which can...

We present a general classification of the conditions under which cognitive science, concerned e.g. with decision making, requires the use of quantum theoretical notions. The analysis is done in the frame of the mathematical approach based on the theory of quantum measurements. We stress that...

Quantum decision theory (QDT) is a recently developed theory of decision making based on the mathematics of Hilbert spaces, a framework known in physics for its application to quantum mechanics. This framework formalizes the concept of uncertainty and other effects that are particularly manifest...
