To a Mathematical Model of Economy and Environment Interaction //Mathematical modelling. 2003. V.15. No.4. P.107-121.
Demberel S.; Olenev, Nicholas; Pospelov, Igor - EconWPA - 2003
This paper presents new results of mathematical modeling of economy and environment interaction. A model of mutual interaction of livestock farming - one in a two main agricultural branches - and natural pastures that are the essential part of livestock farming forage reserve is proposed....

Multiple-Output Production With Undesirable Outputs: An Application to Nitrogen Surplus in Agriculture
Fernandez, Carmen; Koop, Gary; Steel, Mark F.J. - EconWPA - 2002
Many production processes yield both good outputs and undesirable ones (e.g. pollutants). In this paper, we develop a generalization of a stochastic frontier model which is appropriate for such technologies. We discuss efficiency analysis and, in particular, define technical and environmental...

Crop Yield and Price Distributional Effects on Revenue Hedging
Tirupattur, Viswanath; Hauser, Robert J.; Chaherli, Nabil M. - EconWPA - 1996
draw four major conclusions from the results. First, hedging effectiveness using the new crop yield contract depends … using either of the two alone. Third, hedging using price and crop yield futures has a potential to offer benefits larger …

Evaluating the Hedging Potential of the Lean Hog Futures Contract
Ditsch, Mark W.; Leuthold, Raymond M. - EconWPA - 1996
hog futures price, this paper compares the hedging effectiveness of the live hog futures contract to the hedging potential … hedging instrument for Omaha cash hogs and cash loins. The strongest evidence of this is for the short-term hedging of cash … hogs. For the other three meats, no futures contract demonstrated a clear hedging advantage. …

Bayesian Methods for Improving Credit Scoring Models
Posch Peter N.; Gunter, Loeffler; Christiane, Schoene - EconWPA - 2005
We propose a Bayesian methodology that enables banks to improve their credit scoring models by imposing prior information. As prior information, we use coefficients from credit scoring models estimated on other data sets. Through simulations, we explore the default prediction power of three...

Bayesian Semiparametric Regression for Autoregressive Models with Possible Unit Roots
Silva, Ricardo Gonçalves - EconWPA - 2004
In this paper we consider bayesian semiparametric regression within the generalized linear model framework. Specifically, we study a class of autoregressive time series where the time trend is incorporated in a nonparametrically way. Estimation and inference where performed through Markov Chain...

Statistical Inference as a Bargaining Game
Ley, Eduardo - EconWPA - 2001
This paper extends the analogy previously established by Leamer (1978a), between a Bayesian inference problem and an economics allocation problem, and shows that posterior modes can be interpreted as optimal outcomes of a bargaining game. This bargaining game, over a parameter value, is played...

Agricultural Applications of Value-at-Risk Analysis: A Perspective
Manfredo, Mark R.; Leuthold, Raymond M. - EconWPA - 1998
Value-at-Risk (VaR) determines the probability of a portfolio of assets losing a certain amount in a given time period due to adverse market conditions with a particular level of confidence. Value-at-Risk has received considerable attention from financial economists and financial practitioners...

An interaction model for livestock farming and steppe ecosystem // “Mathematical Modeling of Ecological Systems” Almaty: Daik-Press, 2003. – 160 p. Abstracts. P.26.
Demberel S.; Olenev, Nicholas; Pospelov, Igor - EconWPA - 2003
This work builds a macro model for livestock farming based on aggregation of initial micro description for rational control of total number of vintage livestock (age cohorts). All variety of animal kinds is reduced to one by given recount coefficients. An optimal problem on co-hort total number...
