Accounting for Heterogeneity in Performance Evaluation of Norwegian Dairy and Crop-Producing Farms
Alem, Habtamu (Peer reviewed; Journal article, 2023-01-03)It is critical to analyze the performance of enterprises to achieve sustainable agricultural development. Several studies have been conducted to assess farm performance. However, the studies have been criticized for failing ... -
Are diversification and structural change good policy? An empirical analysis of Norwegian agriculture
Alem, Habtamu; Lien, Gudbrand; Kumbhakar, Subal Chandra; Hardaker, J. Brian (Journal article; Peer reviewed, 2018-06-29)We investigated whether diversification and/or structural change would improve Norwegian agriculture. Using a flexible technology approach to account for different technologies, we assessed economies of scope and scale of ... -

Economic performance and efficiency determinants of crop-producing farms in Norway
Alem, Habtamu; Lien, Gudbrand; Hardaker, J. Brian (Journal article; Peer reviewed, 2018)Purpose – The purpose of this paper is to explore the economic performance of Norwegian crop farms using a stochastic frontier analysis. Design/methodology/approach – The analysis was based on a translog cost function and ... -
Effects of model specification, short-run, and long-run inefficiency: an empirical analysis of stochastic frontier models
Alem, Habtamu (Journal article; Peer reviewed, 2018-11-21)This paper examines the recent advances in stochastic frontier models and its implications for the performance of the Norwegian crop producing farms. Unlike the previous studies, we used a cost function in multiple ... -
Endogeneity, heterogeneity, and determinants of inefficiency in Norwegian crop-producing farms
Lien, Gudbrand; Kumbhakar, Subal Chandra; Alem, Habtamu (Journal article; Peer reviewed, 2018-04-27)This paper addresses the endogeneity of inputs and output (which is mostly ignored in the stochastic frontier (SF) literature) in the SF panel data model under the behavioural assumption that firms maximize returns to the ... -
Measuring dynamic and static eco-efficiency in Norwegian dairy farms: A parametric approach
Alem, Habtamu (Peer reviewed; Journal article, 2023-07-18)Eco-efficiency is gaining popularity as a way to measure the agricultural system's economic and environmental performance. In this study, the dynamic eco-efficiency of the agricultural system is assessed using a parametric ... -
Measuring technology and performance differentials among the Norwegian dairy farms
Alem, Habtamu (Peer reviewed; Journal article, 2021-04-30)Purpose The study measures the technology gap and performance of the Norwegian dairy farms accounting for farm heterogeneity. Design/methodology/approach The analysis was based on a meta-frontier and unbalanced farm-level ... -
Melding om årsveksten 2012. Normalårsavlinger og registrerte avlinger
