the main aim of the current paper is the formulating and validation of suitable indices to analyze spatial agricultural development inequalities in fars province. the study was carried out in two phases. in phase one with a review of literature, regarding agricultural development, spatial inequality, along with its indicators, 92 agricultural development indicators were identified. these indice...

This paper discusses the implications of the decomposition property of the Theil index in sequences of nested and hierarchic grouping structures, formalizing general results applicable to a generic sequence of grouping structures. A specific application to data on wages and employment by industrial classification to measure the evolution of wage inequality through time will be explored, analyzi...

Tornqvist-Theil indexes of outputs and inputs are constructed. These data are used to construct indexes of productivity growth over the postwar period. The productivity indexes can be derived from a flexible multioutput-multifactor representation of the structure of production constrained to constant returns to scale. Total factor productivity grew at an average annual rate of 1.75%, compared w...

In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-produc...

This paper investigates bundle pricing under imperfect competition. In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-product generalizations of the Herfindahl-Hirschmann index (GHHI) capturing cross-market effects of imperfect competition on bundle pricing. The GHHI model is applied to pr...

ABSTRACT Faced with the transition in global energy structure shift consumption of fossil fuels to renewable and clean sources, there has been an increase demand for forest biomass purposes, especially wood pellets, imports have grown recent years. Therefore, this study analyzed world concentration pellet from 2012 2018. Data on were obtained Food Agriculture Organization United Nations (FAO), ...

Changes in vegetation activity are driven by multiple natural and anthropogenic factors, which can be reflected by Normalized Difference Vegetation Index (NDVI) derived from satellites. In this paper, NDVI trends from 1982 to 2012 are first estimated by the Theil–Sen median slope method to explore their spatial and temporal patterns. Then, the impact of climate variables and human activity on t...
