A solution for forecasting pet chips prices for both short-term and long-term price forcasting, using genetic programming

Fazli, Mojtaba Sedigh; Lebraty, Jean-Fabrice - HAL - 2013

Nowadays, forecasting what will happen in economic environments plays a crucial role. We showed that in PET market how a neuro-fuzzy hybrid model can assist the managers in decision-making. In this research, the target is to forecast the same item through another intelligent tool which obeys the...

A new approach for estimation of long-run relationships in economic analysis using Engle-Granger and artificial intelligence methods

Amiri, Arshia; Gerdtham, Ulf-G; Ventelou, Bruno - HAL - 2012

In time series analysis, most estimation of relationships and tests are typically based on linear estimators and most classical co-integration methods and causality tests are based on OLS regresses. However the linear functional specification is not necessarily the most appropriate form. This...

Forecasting exchange rates better than the random walk thanks to machine learning techniques

Amat, Christophe; Michalski, Tomasz; Stoltz, Gilles - HAL - 2014

Using methods from machine learning - adaptive sequential ridge regression with discount factors - that prevent overfitting in-sample for better and more stable forecasting performance out-of-sample we show that fundamentals from the PPP, UIRP and monetary models consistently improve the...

Decision making over imprecise lotteries

Rébillé, Yann - HAL - 2005

Since von Neuman and Morgenstern's (1944) contribution to game theory, the expected utility criterion has become the standard functional to evaluate risky prospects. Risky prospects are understood to be lotteries on a set of prizes. In which case a decision maker will receive a precise prize...

Monetary incentives in the loss domain and behavior toward risk: An experimental comparison of three reward schemes including real losses

Etchart-Vincent, Nathalie; L'Haridon, Olivier - HAL - 2011

In the loss domain, both practical and ethical considerations rule out the systematic use of an incentive-compatible procedure involving real losses. The experimental study presented here aims at investigating whether some easier-to-implement procedure could be adequately used. For that purpose,...
