PRODUCTION INTERRELATIONSHIPS IN SRI LANKAN PEASANT AGRICULTURE

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 and four variable inputs. Restrictions based on competitive behaviour and a twice continuously-differentiable production function are maintained in the non-linear least squares estimation. A number of important interrelationships in individual product supplies and input demands are identified, further documenting the need to account for intercommodity production relationships in econometric and simulation studies and in policy formulation. Non-joint production and Hicksneutral technical change are both rejected.     

Comparative Analysis of Ownership Transformation and Performance Relationship among Major and Regional Banks in Australia

This article attempts to clarify existing doubts with respect to the performance of private and privatised banks versus public banks; that is, it is an attempt to clarify the ownership–performance relationship. The analysis takes explicit account of the privatisation transformation, including its intermediary stage, and the status of the economy. The ownership–performance model is estimated using cross‐sectional time‐series data and is used to test the influence of ownership changes on performance. Alternative performance measures are considered. The empirical findings show that ownership transformation in the case of regional banks has resulted in improved performance, whilst the benefits in the case of major banks were not significant, even though these banks have become more competitive.     

PRODUCTION TECHNOLOGY AND INPUT ALLOCATIONS IN SRI LANKAN MULTICROP FARMING

A primal production analysis is conducted of 182 farm households producing multiple outputs in the Sri Lankan dry zone. The approach involves systems estimation of the production functions with first-order equations for variable inputs and permits recovery of the production technology for each crop. Land and family labour are regarded as constraining inputs. Shadow prices are computed for the constraining inputs and yield important implications for increasing household profits. Evidence of global homotheticity in a subset of three inputs is found for three of the crops. Weak separability is rejected in all tested subsets except for fertiliser and chemicals used in the production of vegetables. Input demand elasticities are computed for allocations satisfying necessary and sufficient conditions for profit maximisation. Highly elastic conditional input demands and output supplies are implied.
