Nonparametric Estimation of Multiproduct and Product-Specific Economies of Scale

The Impact of Scale Economies and Product Variety on Forieng Trade and the Study of the Causality Relationship Between Them: The Case Study of Iran’s Manufacturing Industries

In this research, the impact of scale economies and product variety on the foreign trade of Iranchr('39')s manufacturing industries with its major trading partners is examined. While using the data of Iranchr('39')s manufacturing sector at two digit level, a translog production function was used to evaluate the economies of scale in this sector. The data covered the period between 2001 to 2015....

New evidence on returns to scale and product mix among U.S. commercial banks ¬リニ

This paper presents new estimates of scale and product mix economies for U.S. commercial banks. We compare estimates derived from fitting a translog function to bank costs with estimates derived from nonparametric methods. We refine measures of scale and product mix economies introduced by Berger et al. (J. Monet. Econ. 20 (1987) 501) to accommodate nonparametric estimation, and estimate confid...

Nonparametric Estimation of Spatial Risk for a Mean Nonstationary Random Field}

The common methods for spatial risk estimation are investigated for a stationary random field. Because of simplifying, lets distribution is known, and parametric variogram for the random field are considered. In this paper, we study a nonparametric spatial method for spatial risk. In this method, we model the random field trend by a local linear estimator, and through bias-corrected residuals, ...

استفاده از مدل ناپارامتریک تصادفی فراگیر داده‌ها (StoNED) برای محاسبه کارایی انرژی تولید گندم در استان مازندران

In current research, energy efficiency and technical efficiency of wheat farmers were calculated in Mazandaran province. To estimate technical efficiency the Stochastic Nonparametric Envelopment of Data (StoNED) was used. The model incorporating nonparametric data envelopment analysis model which contain the smoothness and concavity constraints with stochastic frontier analysis model. The requi...
