Technical change and the extent to which commodity supplies and input demands are interrelated in Sri Lankan peasant agriculture are explored in this paper. Using a multiple-product dual model, a seemingly unrelated system of product supply and input demand equations is estimated for four crops...

A nonparametric approach to short-run production analysis from a cost and profit perspectives is developed in the context of an adjustment-cost model. The adjustment-cost hypothesis is incorporated in the theoretical framework in the form of the properties of the firm's technology with respect...

This paper examined cost efficiency differences between rural hospitals participating in the Critical Access Hospital (CAH) Program and a group of non-converting, prospectively paid rural hospitals using both a two-stage semi-parametric approach as well as stochastic frontier analysis (SFA)....

This study examines cost minimizing behavior and efficiency measures for a sample of Kansas wheat producers, using nonparametric methods. As such, it verifies the applicability of nonparametrics within a production economic framework.

Seafood consumption in the U.S. has increased over the period 1990 to 2003. A large percentage of the seafood consumed in the U.S. is imported. The most important seafood products imported to the U.S. are shrimp, Atlantic salmon, tilapia, catfish, crayfish, mussels and a mixture of mollusks. In...

A dynamic bio-economic model is used to show that, without technological and policy intervention, soil nutrient balances, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise from a very low base by more than 50%...

Development is a human problem and is aimed at changing man and his economic, social, ecological environment. Throughout history, man has acquired new knowledge to shape his future. As human needs multiplied and became more complex, science and technology – processes of systematic inquiry for...

This paper demonstrates the existence of a unique solution of the PMP problem when both observed output quantities and limiting input prices are taken as calibrating benchmarks. This version of PMP avoids the use of a user-determined small positive number ε originally introduced for...

The productivity is a key issue in economics as it is one of the factors affecting the economic prosperity. An analysis of the agricultural production has a special place in economics of agriculture due to its high dependency on many factors. Therefore, many authors try to define what and to...
