Rice production structures in Sri Lanka: The normalized translog profit function approach

Asian Journal of Agriculture and Rural Development, 2016
This study attempts to estimate the output supply and input demand elasticities of rice production using the restricted normalized translog profit function for the four major paddy producing districts; Anuradhapura, Hambantota, Kurunegala and Polonnaruwa in Sri Lanka. In addition, elasticities of substitution between inputs are also estimated.

Deterministic vs. Stochastic Methods for Frontier Estimation: Update and Illustration [PDF]

Operations Research and Decisions
We estimate and compare a deterministic production frontier to a production frontier estimated using stochastic methods. This comparison is illustrated by estimating the Lerner index of monopoly power for a public sector producer.

Is Technological Heterogeneity the Key to Sustainable Coffee Production Efficiency?: A Latent Class Frontier Analysis in the Traditional Coffee Region of Colombia

Journal of Agricultural Economics, EarlyView.
ABSTRACT Coffee producers deal with uncertainty due to high volatility in coffee prices. To navigate these challenges, producers must balance the tradeoff between higher yield and better quality utilising heterogeneous technologies, such as intensive production methods and environmental management practices.

Determinants of technical efficiency in duck production in southwest Nigeria

Agricultura Tropica et Subtropica, 2018
The need to complement the supply of animal products with other sources of poultry necessitates exploring the potentials of domestic duck production. Studies conducted on indigenous ducks in Nigeria have paid less attention to the resource requirements ...

Food, Affluence and the Consumption Basket*

Economic Papers: A journal of applied economics and policy, EarlyView.
There are significant disparities across nations in incomes and spending. For example, consumers in the poorest countries spend more than half of their income on food, while in the richest, this is one‐tenth or less. We use data from the International Comparison Program for 176 countries to estimate cross‐country demand equations focusing on food and ...
