The availability of efficiency estimation software freely distributed via the internet and relatively easy to use recently inflated the number of corresponding applications. The resulting efficiency estimates are used without a critical assessment with respect to the literature on theoretical consistency, flexibility and the choice of the appropriate functional form. The robustness of policy suggestions based on inferences from efficiency measures nevertheless crucially depends on theoretically well-founded estimates. This paper addresses stochastic efficiency measurement by critically reviewing the theoretical consistency of recently published technical efficiency estimates with respect to economic development. The results confirm the need for a... |

This research contributes to the ongoing discussion on functional flexibility and theoretical consistency by comparing the empirical performance of two second order flexible functional forms - the Symmetric Generalized McFadden and the Transcendental Logarithmic. It proposes an estimation procedure to enhance the domain of applicability for the Translog by a combination of matrix decomposition, classical non-linear estimation techniques as well as bootstrapping based resampling. The validity of the proposed procedure is exemplified by applying it to a sample of small-scale farmers. The results show that the range of theoretical consistency can be crucially enhanced for the Translog functional form by maintaining its flexibility and statistical... |

Drawing on Nahapiet and Ghoshal's (1998) distinction between the structural, relational, and cognitive dimensions of social capital, this paper analyses the performance of Water Communities (WCs) in the Bregalnica region of the Republic of Macedonia. WCs are farmer-managed local irrigation systems which are critical to livelihoods in Bregalnica. Data on the performance of the WCs and role of social capital was collected via in-depth interviews and a farm survey (n=249) of both members and non-members. Results highlight the importance of social capital in explaining the decision to join a WC, the satisfaction of members with their WC, and payment behaviour. |

While mergers, both horizontal and vertical, have been shaping the landscape of the agri-food industry in Europe, the implications of the changing market structure on the level of innovation has not been studied yet. In this paper we deal with the link between innovation and market structure using the empirical example of the Danish agri-food industry. The purpose of this paper is two-fold. First we test for the importance of vertical integration on innovation. While there exist several studies on this linkage, to our knowledge, this is the first that deals with the agri-food industry. Secondly, we examine both product proliferation and innovation. To our knowledge, there are no other similar studies that examine both aspects using the same data set. We... |

Drawing on survey data, this paper identifies the determinants of variations in farm gate milk prices for three CIS countries (Armenia, Moldova and Ukraine). We apply a multi-level modeling approach, specifically a bootstrapped and selectivity bias corrected mixed-effects linear regression model. The analysis suggests three main strategies for farmers to improve the price received for their output: consolidation, cooperation and stable supply chain relationships. While selling through a marketing cooperative has a significant and positive effect on farm gate milk prices, the majority of non-members are reluctant to join. The size of dairy operations, trust and contracting also impact positively on the prices received by farmers. Policy implications are... |

This research aims at shedding empirical light on the relative efficiency of small-scale maize producers in Romania. Farmers in transition countries still face heavily distorted price systems resulting from imperfect market conditions and socioeconomic and institutional constraints. To capture such distortions we formulate a stochastic shadow-cost frontier model to investigate the systematic input-specific allocative inefficiency. We further adjust the underlying cost frontier by incorporating shadow price corrections and subsequently reveal evidence on farm specific technical inefficiency. Different models are estimated due to the imposition of curvature correctness and the effects on the individual efficiency estimates are shown. The empirical results... |
