The paper introduces a notion of complementarity (substitutability) of two signals which requires that in all decision problems each signal becomes more (less) valuable when the other signal becomes available. We provide a general characterization which relates complementarity and...

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 considers the problem of changing prices over time to maximize expected revenues in the presence of unknown demand distribution parameters. It provides and compares several methods that use the sequence of past prices and observed demands to set price in the current period. A Taylor...

In the current paper, we quantify the effect that fuel prices have on vehicle prices' responsiveness to fuel economy. We apply a hedonic price model to the German automobile market by using data on detailed technical specifications of high-sales vehicles of three sequential model years. In the...

The aim of this paper is to analyze the factors that explain the industrial leadership of a Brazilian bus bodywork manufacturer (Marcopolo). From a methodological point of view, the paper was a case study based on bibliographic review and on in-depth interviews. The underlying hypothesis is...

We experimentally explore individual and interactive decision making ina sequential search task and test whether generally accepted principles ofbounded rationality (aspiration formation, satisficing, and aspiration adjustment)adequately explain the observed search behavior. Subjects can, at...

Bargaining under uncertainty is modeled by the assumption that thereare several possible states of nature, each of which is identied with abargaining problem...

This paper provides an analysis of individual and social decision criteria foralternatives that are composed of several attributes. We derive additive and multiplicativecriteria for individual decision-making with new axioms and apply these criteria toobtain new justications of known social...

The influence of risk aversion on the decision to become self-employed is a much discussedtopic in the entrepreneurial literature. Conventional wisdom asserts that the role model of anentrepreneur requires to make risky decisions in uncertain environments and hence thatmore risk-averse...

This study validates a survey-based measure of general risk attitude by an incentivecompatible experiment among more than 900 participants in rural Thailand. The surveymeasure of self-assessed risk attitude provides a useful approximation of the experimentallyderived risk attitude. This holds...
