The city gas sector in Seoul, the capital of South Korea, consists five locally monopolized companies. As penetration reaches 98% and as cooking fuel heating is being converted to electricity district system, respectively, need redefine role raised. In this respect, study aims analyze economies scale using translog variable cost function model over period 2008–2020 compute minimum efficient sca...

Abstract Background Farm productivity on smallholder family-owned crop farms remains low despite several interventions to transform agriculture especially in developing countries. Farmers rural areas face serious constraints that impede their productive capacities for the principal dietary staple, notably maize. Smallholder farmers have access unprofitable markets turn make enterprises less pro...

Based on stochastic frontier analysis and translog input distance function, this paper examines the total factor energy efficiency of China’s industry using input-output data of 30 subindustries from 2002 to 2014, and decomposes the changes in estimated total factor energy efficiency into the effects of technical change, technical efficiency change, scale efficiency change and inputmix effect. ...

Two econometric issues arise in the estimation of complete systems of producer or consumer demands when many non-negativity constraints are binding for a large share of observations, as frequently occurs with micro-level data. The rst is computational. The econometric model is essentially an endogenous switching regimes model which requires the evaluation of multivariate probability integrals. ...

This paper explores the link between trade liberalization and firms’ performance in Egypt combining macro micro data. Using Economic Census of 2013, we examine association tariffs non‐tariffs measures (NTM) imposed on intermediate input sand total factor productivity (TFP). In a first step TFP is estimated as residual Cobb‐Douglas/Translog production function thesecond, regressed weighted NTM i...

Introduction The increasing population growth and the need for more agricultural products on the one hand, and on the other hand, the limitations of agricultural development are problems that human beings have always tried to solve. Due to the limited resources and inputs of production, it seems that further production growth is possible through advanced technologies. In fact, technology is so...

iran is one of the most energy-rich countries subsidizing energy carriers, especially in the agricultural sector, to the extent that the resulting growth is at the expense of the environment. this study tries to investigate the potential impacts of energy price reform on the agro-environment, based on the marginal abatement costs (macs) of emissions. firstly, the energy demand function of the a...
