Portfolio Blender : Blending Qualitative Expectations in Portfolio Optimization

Susinno, Gabriele - 2014

This note presents the Blender, a concept that was developed at Unigestion by the Quantitative Research Hedge Fund Team. In the context of portfolio optimization we propose Blended portfolios as an alternative to efficient portfolios.Albeit Blended portfolios are sub-optimal in the mean-variance...

Augmented AI-Knowledge Driven Intelligent Systems for Adversarial-Dynamic Uncertainty and Complexity

Malhotra, Yogesh - 2023

Goal: ISO 31000 Risk Management (RM) recently re-defined risk as the effect of uncertainty on an organization's ability to meet the objectives. Earlier, it defined risk as a combination of the probability and scope of the (predicted) consequences. The revised ISO Risk advances beyond a static...

More powerful cluster randomized control trials

McConnell, Brendon; Vera-Hernández, Marcos - 2022

Balanced experimental designs, in which the number of treatment and control units are the same, do not maximize power subject to a cost constraint when treat-ment units are more expensive than control ones. Despite this, such balanced designs are the norm in economics. This paper describes...

Focusing on the Focusing Illusion...

Beja, Edsel Jr. - Volkswirtschaftliche Fakultät, … - 2013

The paper presents evidence that validate the focusing illusion. Specifically, the forecasted impact of a basketball championship on students’ subjective well-being was exaggerated because of their intense focus on the event. However, the self-reported states of being for life domains not...

Predicting Compliance : Leveraging Chat Data for Supervised Classification in Experimental Research

Hausladen, Carina Ines; Fochmann, Martin; Mohr, Peter - 2023

Many experimental research designs offer participants the opportunity to chat with each other. While experimental research has traditionally treated text as process data, this paper proposes a novel approach to interpret and use chat data in a structured supervised classification task....

An experiment on partnership protocols for bilateral trade with incomplete information

Sopher, Barry; Sopher, Revan - 2012

We study experimentally partnership protocols of the sort proposed by Kalai and Kalai (2010), for bilateral trade games with incomplete information. We utilize the familiar game analyzed by Chatterjee and Samuelson (1983) and Myerson and Sattherwaite (1983), with a buyer and seller with value...

Tax me if you can: An artefactual field experiment on dishonesty

Jacobsen, Catrine; Piovesan, Marco - Institut for Fødevare- og Ressourceøkonomi, … - 2015

In this paper, we test whether increased salience of a tax charge increases dishonesty using a version of the die-under-cup paradigm. Participants earn money in proportion to the outcome reported and, thus, have an incentive to over-report. We find a significant increase in high outcomes in the...

Discerning Efficiency Shortfalls Without Knowing Valuations

Harstad, Ronald M. - Economics Department, University of Missouri - 2014

Laboratory experiments employing an induced-values methodology often report on allocative efficiencies observed. That … methodology requires experimenters know subjects' motivations, questionable in laboratory experiments, impossible in field … experiments. Allocative efficiency implies a hypothetical costless aftermarket would be inactive. An allocation mechanism …

Testing for Differences across Genders: A Replication of Ultimatum Game at International Islamic University, Islamabad

HASAN, HAMID; EJAZ, NAUMAN - Volkswirtschaftliche Fakultät, … - 2013

The paper attempts to test the following hypotheses: (i) Are people generally self interested, (ii) If people tend to be generous, what is the motive, i.e., either they fear rejection or do they have a preference for fairness, and (iii) Is there any behavioral difference in bargaining between...

Egocentric framing - one way people may fail in a switch dilemma: Evidence from excessive lane switching

Navon, David; Kaplan, Todd; Kasten, Ronen - Volkswirtschaftliche Fakultät, … - 2013

To study switching behavior, an experiment mimicking the state of a driver on the road was conducted. In each trial participants were given a chance to switch lanes. Despite the fact that lane switching had no sound rational basis, participants often switched lanes when the speed of driving in...
