Stochastic simulation of the economic viability of feedlot finishing steers slaughtered at different weights in southern Brazil

open access: yesBioscience Journal, 2017
The objective of this study was to evaluate the use of stochastic simulations in decision-making regarding the economic viability of feedlot finishing Charolais steers slaughtered at different weights (420, 460 or 500 kg live weight).

Stochastic Dominance and Omega Ratio: Measures to Examine Market Efficiency, Arbitrage Opportunity, and Anomaly

open access: yesEconomies, 2017
Both stochastic dominance and Omegaratio can be used to examine whether the market is efficient, whether there is any arbitrage opportunity in the market and whether there is any anomaly in the market.

Life cycle versus balanced funds: An emerging market perspective

open access: yesSouth African Journal of Economic and Management Sciences, 2017
Background: Inadequate retirement savings is an international challenge. Additionally, individuals are not cognisant of how asset allocation choices ultimately impact retirement savings.

Stochastic Programs with First-Order Dominance Constraints Induced by Mixed-Integer Linear Recourse [PDF]

open access: yesSIAM Journal on Optimization, 2008
We propose a new class of stochastic integer programs whose special features are dominance constraints induced by mixed-integer linear recourse. For these models, we establish closedness of the constraint set mapping with the underlying probability measure as a parameter.

Anomaly in decision making under risk: Violation of stochastic dominance among farmers in Gujarat, India

open access: yesIIMB Management Review, 2018
We investigate farmers’ decision making under risk by eliciting their willingness to pay for hypothetical risky income distributions. We also investigate whether farmers behave differently to price and yield risk.

Long-term X-Ray Outburst in the TeV-detected Blazar Mrk 501 in 2021–2022: Further Clues for the Emission and Unstable Processes

open access: yesThe Astrophysical Journal Supplement Series, 2023
This paper presents the results of a detailed X-ray timing and spectral analysis of Mrk 501, which are based mainly on the Swift data obtained during 2021 February–2022 December. The source showed strongly enhanced X-ray activity, characterized by a long-

Comment on “A Model of Probabilistic Choice Satisfying First-Order Stochastic Dominance” by Pavlo Blavatskyy [PDF]

open access: yesManagement Science, 2014
We present examples of existing evidence that lead us to be cautious about claims made in the original paper [Blavatskyy PR (2011) A model of probabilistic choice satisfying first-order stochastic dominance. Management Sci. 57(3):542–548] that the proposed model provides a better fit to experimental data than do existing models.

RSD: An R package to calculate stochastic dominance

open access: yesSoftwareX
Stochastic dominance is a classical method for comparing two random variables using their probability distribution functions. As for all stochastic orders, stochastic dominance does not always establish an order between the random variables, and almost ...

On the existence of certainty equivalents of various relevant types

open access: yesJournal of Applied Mathematics, 2003
We tackle the problem of associating certainty equivalents with preferences over stochastic situations, which arises in a number of different fields (e.g., the theory of risk attitudes or the analysis of stochastic cooperative games).
