wheat is the dominant cereal crop constituting the first staple food in iran. this paper studies the energy consumption patterns and the relationship between energy inputs and yield for wheat production in iranian agriculture during the period 1986 – 2008. the results indicated that total energy inputs in irrigated and dryland wheat production increased from 29.01 and 9.81 gj ha-1 in 1986 to 44...

A bank′s capital charge computation is a widely discussed topic with new approaches emerging continuously. Each bank is computing this figure using internal methodologies in order to reflect its capital adequacy; however, a more homogeneous model is recommended by the Basel committee to enable judging the situation of these financial institutions and comparing different banks among each other. ...

In this paper we systematically review and develop nonparametric estimation and testing techniques in the context of econometric models. The results are discussed under the settings of regression model and kernel estimation, although as indicated in the paper these results can go through for other econometric models and for the nearest neighbor estimation. A nontechnical survey of the asymptoti...

the objective of this paper is econometric analysis of iranian agricultural products markets (case study ofpotatoes) by using equilibrium and disequilibrium techniques. sections i and ii proceeds by classification of disequilibrium econometric literature and supply and demand analysis for agriculural products, respectively. in the other parts ofpaper potato market lif iran was hypothesized and ...

One of the fastest growing areas in empirical finance, and also one of the least rigorously analyzed, especially from a financial econometrics perspective, is the econometric analysis of financial derivatives, which are typically complicated and difficult to analyze. The purpose of this special issue of the Journal of Econometrics on “Econometric Analysis of Financial Derivatives” is to highlig...

In this paper we endogenously group 311 U.S. cities by using dynamic clustering techniques. Then, we try to determine what the economic determinants of clustering are. In so doing, we use a spatial econometric model that disentangles the effect of intercity interactions operating through the input-output matrix from the effect of all others interactions. Preliminary incomplete version Do not ci...
