| In 1944, Marschak and Andrews published a seminal paper on how to obtain consistent estimates of a production technology. The original formulation of the econometric model regarded the joint estimation of the production function together with the first-order necessary conditions for profit-maximizing behavior. In the seventies, with the advent of econometric duality, the preference seemed to have shifted to a dual approach. Recently, however, Mundlak resurrected the primal-versus-dual debate with a provocative paper titled “Production Function Estimation: Reviving the Primal.” In that paper, the author asserts that the dual estimator, unlike the primal approach, is not efficient because it fails to utilize all the available information. In this paper we... |

| In a recent paper, Mundlak assumes that the price-taking, risk-neutral and profit-maximizing entrepreneur makes his decisions on the basis of a planning model that maximizes expected profit using expected prices. In the same paper, the author asserts that when there is no sample price variation across competitive firms, it is impossible to estimate the supply and factor demand functions from cross-section data using a dual approach. In a famous paper, titled “To Dual or not to Dual,” Pope asserted a similar opinion. This paper shows that, using Mundlak’s assumption about planning decisions based upon expected profit, it is possible to use a dual estimator to estimate supply and factor demand functions. This objective is achieved by using Mundlak’s... |

| Energy inputs and yield relationship in cassava production was investigated to establish correlation between inputs and output in cassava production in Nigeria. Production data of energy inputs and crop yields were collected from 54 cassava farms in twelve cassava producing villages through site visits, interaction with the farmers and physical measurements for three production seasons (2013-2016). The data were analyzed statistically. Amount of inputs per hectare were calculated and multiplied by coefficients of energy equivalents. Total energy inputs in cassava production in this study was 36,482.8 MJha-1 while average output of cassava tubers was 32, 022.6 kgha-1. Energy use ratio, energy productivity and specific energy of the surveyed farms were 4.9,... |
